Dell U2711 and Lightroom

Hi all,
Just bought 27 inch monitor with max resolution on ~2500 *1450.  (Previously used a dell 1900*1080 Dell monitor)
I am now unable to see any photos in library or see new photos that are loaded in, but lightroom tells me they are there.
Photos load into CS5 with the same monitor and are visible OK.
Would be grateful for any advice

Hi All,
Calibrated the screen set at "custom colour" , all photos now visible- most peculiar

  • Using Wide Gamut (Dell u2711) With Lightroom

    I have just completed an upgrade of my computer system to include 2 Dell U2711 27" monitors.  I am using LR 3.5.  My system is running with Windows 7 64 bit and a ATI Firepro graphics card running the displays. 
    Before purchasing these, and listening to the chatter on various forums I was led to belive that I was going to get garish coloration on all applications except Adobe LR and CS5.  This does not seem to be the case.  LR and CS5 are fine and the other applications IE and Windows Office seem to be OK as well.
    These displays are calibrated at the factory.
    Does anyone have any experience with these and can share any "gotchas" with me.
    Henry

    Well I am glad that I am taking my time on this calibration process.  I thought I had it understood correctly.  I am making my dialog with Dell a part of this message so you can see the exchange I had with their 2nd level of support and I am also a document from Dell engineering.  Please take a look at these and I will call Dell again if necessary.
    Sorry For The Long Post

    FROM MY EXCHANGE WITH DELL:
    It would be excellent if I could use a calibrated “custom” present on the monitor for LR and CS5 and simply select one of the presets (sRGB or Adobe RGB) when I am not using LR and CS5.   I am not running with any monitor profile and a generic PNP driver now and I am getting much better results than I expected.  I would just un-select the profile when I did not want to use the calibrated “custom” preset. 
    Based on the data engineering provided me in  the document I sent that is correct( Yes).

    David, Please just say yes or no to this:
    Are you telling me that ONLY the “custom” preset will be altered and that the other presets will remain at the “factory” settings. 
    Yes or No, believe me it is very important and will increase sales of this monitor if this statement gets passed along as true.  Is this worth a  conversation between you and engineering to verify?  It would be to me and the rest of us photographers.  Sorry, but this statement in the documentation is not the way I used to word my writings as an electrical engineer back in the day.

    David,
    I still need clarification here.
    “My personal suggestion is that since you are doing custom photo/video work that these LCD are being used for, I would calibrate them for your business purposes and  leave as such. With the enhanced video settings normal internet browsing and  such will have better clarity.”
    Are you telling me that ONLY the “custom” preset will be altered and that the other presets will remain at the “factory” settings.  This is an important question for all of us who want to use this monitor for photographic work.  If we photographers can have one of the presets, namely, “custom” calibrated, and the others left as shipped then we can choose the customer preset for our work and switch back to sRGB or Adobe RGB for routine office and billing functions.   If this is true, and the photography world learns of this, Dell will sell a lot of U2711s, especially considering that the U2711 is an excellent price performer. an
    I have been doing research on this for myself and to share with a number of user forums on photography.  I want to get right for my own use and for sharing with the photography community.

    Henry,
    Per the documents  as with any calibration you must be careful and  aware of settings you change. Use the setting CUSTOM COLOR if you want to calibrate using your own equipment as per document.
    In regards to your question on your video card as the manufacture /forums recommends you should disable any color managements since you are using your own color/video calibration tools.
    My personal suggestion is that since you are doing custom photo/video work that these LCD are being used for, I would calibrate them for your business purposes and  leave as such. With the enhanced video settings normal internet browsing and  such will have better clarity.
    Have a good  day.

    Good Evening David,
    Thank you for taking the time to discuss color management for my recently acquired U2711 monitors.
    According to what we discussed when I use calibration hardware and software you mentioned that I should use only the “custom” setting and that once I calibrated the monitor “all”  factory setting would be overwritten and cannot be restored.  When I read the word document you sent me I believe I am seeing something that needs clarification:
    Question 7 from the word document:
    7.         Is it possible to revert to factory pre-tuned settings after I color calibrated my unit with my equipment?
    The customer should not re-calibrate and save your result in sRGB and AdobeRGB preset modes.  Once overwritten, it is not possible to revert back to factory pre-tuned setting.  The customer is advised to use the "Custom Color" preset mode to do their own calibrations.
    Does this mean that only the “custom” preset is altered from the factory setting to store the results of my calibration?   Does this mean that if I use the “custom” preset only for calibration that sRGB and AdobeRGP will not be changed from the factory setting?  Does this mean that each of the U2711 presets have its own LUT table?  Can you please clarify?
    If this turns out  to be the case I can use the sRGB preset, with no profile as it is now, for routine processing with non-color aware applications, and then select the newly calibrated “custom” preset when doing photo processing.  Is this the case?  After reading the attachment I believe I have to be very careful not to negatively affect my monitors as they cannot be reverted to factory settings. 
    I have done some additional research that includes the relationship between monitors and some high end graphics cards such as the ATI Firepro V5800 card I am using.  This research indicates that I should disable any efforts by the graphics card to do color management lest I interfere with the efforts to calibrate the monitors.
    I am probably being a bit picky but having more than 50 years in the technical end of computers I have been burned more than once having two elements of a computing system fight each other.
    Again, thank you for your help on this.

    FROM THE ENGINEERING DOCUMENT: (SEE QUESTION 7)
    Service & Support:
    1.         Can I request Dell to re-calibrate my monitor during the warranty period?
    Calibration is done for only new monitors shipped from factory.
    Each unit is factory-calibrated as part of the production process.
    Dell will not be able to re-calibrate the monitor during warranty
    Period as calibration is done only for new units.
    2.         Can I request Dell to provide another Color Calibration Factory Report in the event of the loss of or damage to the report?
    Each Color Calibration Factory Report is unique to each Dell monitor and cannot be reprinted.
    We would recommend that the customer takes care to retain the Color Calibration Factory Report if required.
    3.         Is there a specification for color accuracy? If so, how do I check if my monitor meets the specification?
    Dell calibrates the U2410/U2711 according to the DeltaE(1931) standard using equipment that can accurately measure high color gamut panels.
    4.         Will Dell guarantee all replacement units are also color calibrated?
    The color calibration is only done for new units shipped from factory; thus, replacement units will not be color-calibrated.
    5.         In the event of warranty exchange, will the replacement unit come with a similar Color Calibration report?
    Dell does not do the color calibration on the replacement units, as such, there will not be a Color Calibration Factory Report or similar attached to replacement units.
    In cases where a brand new unit from factory needs to be shipped as a replacement unit, a Color Calibrated Factory Report will be shipped with it.
    6.         Why does Dell only provide the Color Calibration Factory Report for new factory units of U2410/U2711?
    The color calibration is done at factory to ensure color is accurate for each unit of U2410/U2711 when it reaches the customer.
    7.         Is it possible to revert to factory pre-tuned settings after I color calibrated my unit with my equipment?
    The customer should not re-calibrate and save your result in sRGB and AdobeRGB preset modes.  Once overwritten, it is not possible to revert back to factory pre-tuned setting.  The customer is advised to use the "Custom Color" preset mode to do their own calibrations.
    8.         How do I use this Color Calibration Factory Report?
    The Color Calibration Factory Report is provided for customer’s reference that Dell does color-calibration on the U2410/U2711 to ensure color accuracy and consistency for each unit of U2410/U2711 shipped.
    9.         My own measurements of sRGB, gamma or AdobeRGB are not meeting the values stated in the report. Why is this so and can I get an exchange?
    One of the reasons could be the different type of color calibration equipment used. There are many types of color calibration equipment in the market.
    Dell ensures Color Accuracy based on the Dell approved Color-Calibration equipment at Dell’s factory.

  • Request - ICC profile for the combination - w520 and Dell u2711

    Greetings,
    Due to the lack of a colorimeter, I come to you with a humble request for few calibrated ICC profiles for the DELL u2711 and the quadro 2000m w520. Probably tftcentral's review might be a well guidance for setting up a ICC profile http://www.tftcentral.co.uk/reviews/dell_u2711.htm
    Thanks in advance,

  • Is it posible to connect dell u2711 with display port to thunderbolt display.

    I want to buy a macbook pro 15 2011 and thunderbolt display.
    But I got a dell u2711 and I want to use this screen.
    my question. Can I connect macbook pro to thunderbolt to dell u2711. for dual 27 screen

    Yes, you can.
    I have a similar configuration : same monitor but my macbook pro is late 2013. use a displayport cable for best results. you will be able to get 2560 x 1440 resolution.

  • Resolution issue with macbook pro 13 (late 2013) and dell u2711

    I have a Dell U2711 (native resolution 2560x1440) that I use without issue with a macbook pro late 2007 (running 10.10.x), various iMacs and Macbook air 2011 running 10.10. When I say without issue, the display works at its native resolution.
    Last week we got a MacBook Pro 13in, late 2013 model.
    If I connect this macbook via either thunderbolt connection to the u2711 using either DVI port on the dell, the maximum resolution that I can use is 1920x1080. I am using apple mini displayport to DVI adaptors (I have tried 2 different ones and 2 different DVI cables, with no improvement). Clicking option + scaled in sys prefs does not give the native resolution as an option.
    However, I just discovered that if I use a DVI to HDMI adaptor and I connect the macbook to the display I get the full native resolution without issue (2560x1440).
    I have zapped the pram, powered down the display etc etc etc and it made no difference.
    I would prefer to use the mini DIsplayPort to DVI adaptor rather than HDMI, any suggestions appreciated.
    TIA.

  • Weird Colour Saturation issues with MBA and Dell U2711

    Hey all,
    Just picked up a new Dell U2711 for use with my MBAir and my PC Workstation. I have the MBA hooked up to the monitor via the DVI imput with the official Apple Mini DisplayPort to Dual-Link DVI Adapter. What i'm experiencing is some bizzare colour saturation discrepancies. I've attached two screenshots to illustrate the issue...
    For some reason, icons in the dock and in Launchpad are displaying WAY more saturated than their icons when displayed in a regular finder window.
    Has anyone else seen anything like this? Any ideas where I could start looking to find a solution?
    Thanks!

    Just updated the post with a new screenshot that better illustrates the problem. I origainly had a firefox issue as well, but that was fixed by changing the colour correction settings in that application.

  • Lenovo ThinkPad X1 and Dell U2711 / HDMI?

    Hello, 
    I plan to purchase the Dell U2711 monitor, it has a resolution of 2560 x 1440. 
    Will my Lenovo ThinkPad X1 handle this over the HDMI port?
    Thanks in advance,

    Not thru HDMI, but it will thru the mini-display port. You simply need a mini-display port to full size display port cable, something like this.

  • Advice needed on monitor for Photoshop and Lightroom use

    Hi. I am aserious amature photographer wishing to move to the next level and sell some of my work.
    I just had a custom pc built to work with the new copies of Photoshop CS5 and Lightroom 3 I bought (lots or RAM and HD space, ssd, etc....)
    The last piece of my system is to purchase a monitor. I want to be somewhere in the better then Best Buy but less than NEC/Eizo range in price, or between $500 - $900. I have worked with cameras since the early 80's and moved to digital several years ago but the only post processing I have done is with Photoshop Elements.  I would be doing mostly prints to sell but also need to have a web site to do so. Will also use the pc for daily net surfing... but do not game or watch a lot of video on the pc.
    Being really new to this whole process I have a few questions.
    The first thing I need to decide is whether I need to look for a wide gamut display or not.
    I realize the whole chain must be 10 bit (Adobe -OS - graphics driver - graphics card - display port.
    I have Adobe Photoshop CS5 and Lightroom 3, Win7 64 bit, Zotac ZT 50701 10M video card (which uses GeForce GTX 560  fermi and an nvidia chipset. It does have displayport). I am having a hard time determining whether my video card actually supports wide gamut (10bit).
    Standard vs Wide Gamut? Is wide gamut important enough to deal with the issues it brings (calibration, viewing things other than PS and LR or color managed, which appear to be rare?) Is sRGB good enough for most prints (don't do fine art, mostly nature and portraits but starting to do some HRD things). If wide gamut is the way to go I have no problem with that and have the time to learn about calibration, color management, etc... But I also want to make sure the juice is worth the squeeze.
    24" vs 27"? Is there any advantage to one or the other when editing photos?
    IPS vs PLS? I realize they are similar but are there differences worth noting?
    Glossy vs Matte Anti-Glare? seems to be a lot of comments regarding the anti-glare coating, mostly poor. Yet I can see issues using a glossy screen in my study with a window to my back.
    One manufacturer vs another? I realize Eizo, NEC and LaCie are at the top of the heap. But with my budget, after upgrading my pc and camera equipment, I can't make that work now. So I need to choose from the next group down (Dell, HP, Samsung, Asus...)
    One or two monitors? It looks like many (mid-grade) wide gamut monitors do a lousy job of displaying anything but color managed sites. Is that necessarily true of all the mid-grades? Or can some be used for graphics but as well for routine net surfing, MS Office, etc...? Or am I better off getting two monitors, one for graphics and one for the rest? That would pretty much limit me to 24" or less given my budget (used to using a Dell 21" TN monitor that oddly crapped out just as my new pc was done).
    The more I read reviews the more confusing it gets. There seems to be a difference of opinion even among pros on whether to go wide gamut or stick with an easier sRGB. Realizing a standard gamut monitor would be cheaper, I do want to make the right decision up front, given my budget.
    The one thing I have found astounding is that there is nowhere to actually see many of the monitors I am considering. We live in Nashville TN but my wife is from Atlanta Ga so we drove there a few weeks ago to visit family and for me to visit monitor shops. Even the largest ones there (Fry's and Microcenter) had minimal IPS monitors, a few Dells and HP's. The knowledge of their sales folks was so poor I finally gave up. Felt bad about this until I posted this on another board and got a reply from a guy in LA (second largest city in the US) that he wanted to see a particular monitor and there was no place even there to do so.
    Anyhow, here is what I have considered:
    24" Wide Gamut: Dell U2410 and Asus PA246Q. Dells appear to be good IF you get a good one. The Asus appears to be a clone of the Dell that gets a lot of good press.
    27" Wide Gamut: Dell U2711 that also gets a ton of good reviews
    24: Standard Gamut: Dell U2412 and HP ZR2440.
    27" Standard Gamut: Samsung S27A850D and Apple Cinema- The Samsung uses PLS technology versus IPS while the Apple is a glossy screen that will work with a pc.
    Sorry for the long post. Any comments are greatly appreciated.

    Not trying to talk you out of setting up a 10 bit pipeline, but it's still not very mature, and it really isn't a necessity to get a good editing experience.
    Personally I find advantage in using two 4:3 ratio monitors for Photoshop work.  All my panels are on the right monitor, while pretty much the entire left one shows the Photoshop main window and the working canvas space.  My desktop is 3200 x 1200 pixels overall, and I find having the panels remain visible all the time is important.
    Regarding whether a wide gamut is important...  Will you be printing to devices that deliver a wide gamut?  What other things will you be doing with your system?
    It's not a no-brainer whether a wider gamut monitor is always "better" for everything, since it can accentuate the differences between the output from color-managed and non-color-managed applications, and it's definitely true that not everything is color-managed.  With a monitor that's close to sRGB, for example, you might find Internet Explorer output acceptable, while using a wide gamut monitor will result in garishly oversaturated IE displays.  On the other hand, FireFox (with a settings tweak) seems to get color management right, so there is an alternative.
    I think, as John has implied above, you should work to get your head completely around how color-management works, soup to nuts.  If you don't, there will always be things that are a mystery or which surprise you at the wrong times.  Being able to order a print and have it come back with the expected color can be very important, as you might imagine.

  • Considering a Dell U2711 for MacMini Server

    Hi All,
    I am planning to buy a MacMini Server to go with my Dell U2711 Display.
    I am a bit confused regarding the means of connecting the Display to MacMini for running at 2560 x 1440 resolution.
    Apple tells on MacMini specifications page, that output through HDMI is limited to 1920-by-1200.
    That said, I am left with the "Thunderbolt" way to achive the native resolution of 2560 x 1440, right?
    So, what cable should I use to connect the display through thunderbolt port?
    Some articles suggest using the so called "Mini DisplayPort to Dual Link DVI" Cable to do that, but then isn't is a misleading naming for a thunderbolt cable?
    I would expect something like a "Thunderbolt to Dual Link DVI" cable.
    Thanks!

    Iam buying this model, have tou tried 1080p videos external monitors anf full hd flash videos from vimeo?
    please let me know

    Just though I should fill in a bit here, as I have now bought this laptop and running Arch 64bit on it. So if any other users are considering this laptop, here are a few lines about it:
    I have it up and running with LUKS disk encryption, everything works fine so far. I'm running XFCE with just a minor problem that the bottom panel is kinda blinking 3 or 4 times right after boot. Havn't tested webcam nor bluetooth, but sound and everything else seems to work fine.
    Two of my biggest problems were to get the wifi up and running and to get an acceptable performance when viewing videos in full screen. As for the wifi; just me not understanding that I needed a kernel module AND a firmware.. (If someone wants to fill me in on why we need a firmware AND a kernel module/ driver, I'd be glad.) I installed the iwlwifi-5000-ucode without knowing I also needed the iwlagn module too. After that was fixed, I am now using network manager with no problems.
    I have also had some problem with the Radeon 3670. The performance was bad in full screen videos when I used the xf86-video-radeonhd. (I followed arch wiki). It didn't help to use vide-ati neither, and no settings in the xorg.conf did fix my problem. I also noticed that DRI was failing in xorg.log. After alot of trying I decided to try the git-versions which are found in the AUR. I'm happy to say that I can now watch 720 (the only video resolution I have tried yet) with acceptable quality
    All in all, I'm quite happy with the computer so far. A bit warm maybe. Oh,  and the screen (full HD version) is SOO nice :-)

  • Dell U2711 black screen when connected to Mac via DisplayPort

    I currently have a Dell U2711 27" monitor connected to my Mac Mini through DVI (it uses a DVI to mini-DVI adapter at the PC end). However, I cannot get the full resolution of the monitor 1920 x 1080 maximum is offered were the monitors maximum resolution is 2560 x 1440.
    I did some Googling and seemed it required DisplayPort connection to achieve this. No dramas. I ordered a Mini-DisplayPort to DisplayPort cable.
    I plugged this in and all I get on the Dell is a black screen. The monitor doesn't go into power save mode or anything like that, just displays nothing - an illuminated black screen.
    I pulled out my MacBook and connected the cable to that, same deal. The Mac recognises that the cable has been connected (as the laptops LCD goes blue for a second or two while it detects the new monitor).
    Any ideas?
    I also had a DisplayPort to DisplayPort cable here which was included with the monitor from Dell, which I will test aswell when my miniDisplayPort to DisplayPort adapter arrived.

    Yes, that is one means, but...
    However, HDMI 1.3 can also carry resolutions higher than 1920 x 1080 - check out http://en.wikipedia.org/wiki/HDMI - not really an option on the Dell monitor though, as it only supports up to 1080p on the HDMI connection. However, there is a thread elsewhere on the internet of a user who forced his Windows laptop to use 2560 x 1440 resolution via the HDMI output and the Dell monitor accepted it!
    In addition, so can DisplayPort - as per my original post.
    The Apple Dual-Link DVI adapter is plagued with issues and has a lot of faults, so I'd rather avoid it. It is also significantly higher priced than the above option of DP.

  • External Monitor (Dell u2711) problems

    Hi all,
    I'm an editor and just bought a Dell u2711 to hook up to my MacBook Pro (2.53 GHz, 4GB Ram, NVIDIA GeForce 9400M). The DVI would only support up to 1920x1280 so I bought a mini DisplayPort to DisplayPort adapter and that got me up to my full resolution for the monitor.
    HOWEVER... my computer seems to be too slow or the graphics card isn't good enough to support such a monitor. Is this true? When I use the external monitor as extra desk space and put all my FCP windows in it I get this banding on my subjects when they move. It just looks like very slight glitches and the movement isn't displayed so smoothly. I'm working with 1080p ProRes 422.
    When I try and use the Dell u2711 as an external video monitor (display all frames) it lags pretty bad and the motion is stuttery and not showing in smooth motion.
    Please help. Would I have been better off with the 27" Cinema display? I thought they were pretty similar monitors. Is my laptop or graphics card not up to the task? Just last Nov. or so I got this laptop with what I thought was the best available graphics card Apple had at the time for this laptop.

    Go to your Audio / Video Settings >> A/V Devices tab and turn of "Mirror on desktop" for Playback ... this will reduce the load on your system as it will not be trying to decode the video for two separate (and different) playback streams simultaneously ie when using Digital Cinema Desktop Preview to display All Frames then you will not see playback in the Canvas window as well, just on the external preview monitor.
    And/Or you could also try setting FCP's System Preferences >> Playback Control >> Gamma Correction to "Approximate" ... according to the manual this can offer a little performance boost (but to be honest I haven't ever tested this).
    Choosing Real-Time Playback Gamma Correction Options
    Whenever you watch your video on a computer display (such as video displayed in the Canvas, the Viewer, or via Digital Cinema Desktop Preview), Final Cut Pro applies gamma correction to the video to more closely approximate the way it would appear on a video monitor.
    Note: Gamma correction is not applied to external video outputs such as DV or third-party interfaces because this correction is inherently applied by external video monitors.
    If your computer’s graphics card supports gamma correction, Final Cut Pro automatically uses the card for accurate gamma correction. If your computer has an older graphics card that does not support gamma correction, you have two gamma correction options in the Playback Control tab of the System Settings window.
    Accurate: High-quality gamma correction. This option is the most accurate but also requires the most processing power.
    Approximate: Lower-quality gamma correction. This option leaves more processing power available for real-time effects but results in less accurate color and brightness rendition.
    Tip: If your real-time performance is limited, try changing the gamma correction setting to Approximate (if available).
    Hope it helps

  • WIll my MP drive a dell U2711

    I ordered a Dell U2711 as I'm tired of waiting for Apple's new monitor offerings and I never checked if my MP will drive it ok. It has the ATI 4890 HD and the Dell the following inputs : VGA, DVI, Composite, Component, HDMI, DisplayPort.
    I believe the Apple card has a mini display port and dvi out but whcih input to the Dell is used ? Will the DVI work or must I get a mini displayport to displayport cable ?
    Anyone provide comments on this monitor..anyone here using it ?
    Thanks

    Another option is to get a mini display port to display port adapter from monoprice.com for about $10 and you can use the mini display port to drive the monitor if you need the DVI for something else on the card.

  • Problem with Dell U2711

    Hi there
    I just took delivery of a new Dell 27" monitor and there's something wrong with the image at 2560x1440
    I have it connected to my ATI Radeon HD 3870 Graphics card via a DVI cable
    The image is all pixelated
    Can anyone help?
    Dell support is useless and keep asking me for a number that is not on the monitor
    Thanks
    Rob

    Robert.  I am in the process of procuring my first iMac.  Stron preference toward the 27" iMac as it has teh dual Thunderboly ports.  I already have 2 Dell U2711 monitors which I will connect to my iMac to give me a 3 screen setup, but the show stopper is the resolution being limited on the Dell U2711's.  Did you manage to solve the resolution limitation with the screens being limited to 1920x1080 or did you manage to get them to run at 2560x1440?

  • How to Dual Display with Dell U2711

    Hi,
    I am looking to connect my iMac (late 2013) to a Dell U2711 in a dual display configuration. I'd like to be able to use all 2560x1440 pixels of the Dell.
    the Dell has DVI-D (dual channel), Displayport (not mini displayport), HDMI and VGA.
    which port will give me the cleanest picture and best performance and what cable do I need to buy ? (obviously thunderbolt to something...)
    thanks !

I'm not entirely sure what I should be partitioning the C: into, I've done partitions before, just not for Arch and then I'm not sure whether to use GRUB or syslinux, or if I even need those. Or if I need to use GPT or MBR?
    Your disk is already partitionned so you don’t have to choose between GPT or MBR, the choice is already made.
    You don’t partition “C:”, that is the name of a Windows partition. You partition a drive.
    Grub or syslinux, use whatever the beginners guide tells you to. Personally I think syslinux is simpler which is why I’m using it (but I’m not dual-booting, if that matters).
    You’re not saying what your problem is with partitionning, so it’s hard to help.
    Thanks for getting back to me, I'm not sure if I just create one large partition for Archlinux or if I have to create multiple? Where I'm also confused is with the Creating Filesystems part of the guide. I don't understand how I'd do this in Windows, or what /dev/sda1 is referring to.
    As for the bootloader part, the Beginner's Guide gives you a choice between syslinux and grub, what I'm not sure about is which to use considering I'm dualbooting. How it will affect my windows bootloader, do I disregard that and use GRUB now? I'm unclear on how that works.
    I'm also aware I need to disable Secure Boot, I just searched my BIOS options and couldn't find anything remotely relating to that, so I'm assuming it's not an issue since this computer was originally on Windows 7 anyway?
    Thanks again, Expi.
