External monitor blurry image rMBP 2012

Hey guys!
I have 2012 rMPB which works perfectly and i am connecting it to my 22" Benq monitor via MiniDisplayPort to VGA connector (monitor only has VGA).
Image on the external monitor is really bad, it looks blurry, not sharp enough and brightness is very low.I tried calibrating it, no luck
Monitor is working properly (tested on Win laptop) and resolution is set to native FullHD so i dont know what could be the problem...
Any suggestions?

Hi,
I'm facing the same problem. The fonts on an external monitor are very blurry. Graphics and icons are displayed crystal sharp. I can rule out any issue with the monitor or cable (mini DisplayPort to DVI) whatsoever, because if I run Ubuntu in VirtualBox, then within the VM the fonts are displayed sharp. Also no font issues on the notebook display itself.
So it all comes down to a font issue on external displays, as can be read in several forums. The font smoothing tweaks didn't show an effect.
Macbook Air 13" mid-2012
OS X 10.8.2 Mountain Lion (10.8 pre-installed)
External Display: Benq G2222HDL connected via miniDisplayPort to DVI Adapter on the Thunderbolt connection
Can anyone reproduce the correct font display in a virtual machine?
Thanks,
sal_manilla

  • Macbook Pro Retina External Monitor Blurry

    Just got a new macbook pro retina and got it home. After getting everything transferred over from my old toshiba I connected it to my 1 month old HP external monitor and the display is blurry. I have read on many sites that this is a common problem however I can not find a solution. I am hook up from HDMI to HDMI. O don't really want to go through trial and error of different adapter for the lightning port if that will not work. I have tried different HDMI cables to no success. Any Ideas?

    Hi AO1 James,
    If I understand correctly, the external monitor was blurry from the moment you plugged it into your MacBook Pro with Retina display. I would first check the resolution settings for the monitor with the "How do I select additional resolutions on my display?" section of the following article:
    Apple computers: Troubleshooting issues with video on internal or external displays
    If it remains blurry after selecting your monitors optimal resolution, I would use the steps under the "Reset the system" section of the article to help troubleshoot the issue.
    Thank you for using Apple Support Communities.
    All the best,
    Sterling

  • External Monitor blurry with MacBook Pro

    Good day, I have searched the forums but have not found a solution to my problem...
    I recently purchased a Dell 2005FWP External Monitor and plugged it in (DVI to VGA) to my MacBook Pro. It automatically adjusted to a 800x600 resolution which of course is not ideal. The menu gives a long list of display resolutions but most of them are "not available" when I click on them. I have tried switching the docks and the monitors to the opposite sides on "Arrangement" of displays but I still don't get a different menu. I can't seem to find the menu of resolutions for the MacBook Pro either.
    Please let me know what I am doing wrong...Sorry, I know I am clueless!!
    Thank you!

    I have a ViewSonic VX2035wm display connected to my MacBook Pro - the image on the external monitor shows ghosting and double images like we used to see on old tube TVs.
    Here is a post from MacFixIt.com that details my problem.

    Late-2008 MacBooks: Image problems on external displays with mini-DisplayPort converters
    The new MacBooks and MacBook Pros come with a Mini-DisplayPort adaptor for external video, and Apple supplies various adaptors (DP to DVI, and DP to VGA) to accommodate current monitors. Some users are having difficulties with their adaptors when connected to certain monitors.
    Apple Discussions poster Ocell writes:
    "I have the exact same problem with my Viewsonic VG2030wm 20" LCD. I've ruled out bad DVI cables. The Macbook Pro works with my 12" Cintiq's display, and the Viewsonic works with my Intel iMac, so the video out/mini displayport adaptor/dvi cable/viewsonic display are all operational. It's just the specific combination of the Macbook Pro and Viewsonic that doesn't work."
    This problem has been found to frequently occur with DVI adaptors attached to their computers, however it has also happened with users connecting to the VGA adaptors. In these cases, unlike the DVI situation where no signal gets through, users have noticed the screen blinking or shutting off at random times. While drivers may definitely be suspect, the problem appears to be hardware-related since users have experienced the issue both in Mac OS X as well as in Windows via Boot Camp.
    The DisplayPort connections used on the new MacBooks have slight differences in their protocols than other connection types, which allows for expanded functions in smaller connectors, but also can run users into difficulties, especially when older connetion types are used. While there could be software involvement in this problem, it sounds like there's most likely a firmware-related problem that hopefully can be patched by Apple, or at least be accommodated for in a driver update.
    Things to Try
    Reset the monitor to defaults If there is a method for fully resetting the monitor, try doing that first. Most have a menu option to reset to factory defaults, but in addition there may be a way to fully reset the device such as unplugging it for an extended period of time. This information may be available on the manufacturer's website, or users can just try unplugging the device for an extended period such as 20-30 minutes.
    Toggle various monitor setups In the "Displays" system preferences, toggle desktop mirroring on and off to see if the monitor is not just extending the desktop to the second monitor. Especially if users have black wallpaper on their desktops, secondary monitors that are just serving as extended desktops may appear to be off when connected. Alternatively users can try dragging documents off the sides of their main monitor to see if they go over to the second monitor.
    Reset the computer Users might try resetting the computer's PRAM (which does contain some graphics parameters) by holding the options, command, P, and R keys down at bootup until the computer resets and makes the boot chimes again. Release the keys and allow the computer to boot normally. Additionally, users might try resetting the computer's system management controller. Here is an Apple Support article on how to do that.
    Use a different monitor Unfortunately, with hardware problems such as this users will not be able to do much, so if another monitor is available that works then users should switch to that.
    Try another adaptor Many monitors support both VGA and DVI inputs, and there is potential for users to get things working by using another connection type. Additionally, while it may be a long shot, users might also try chaining together various adaptors. For instance, users might try going from displayport to DVI, and then using a DVI to VGA adaptor as the next connection, to see if that somehow sends a proper signal to the monitor.

  • External monitor resizing image from timeline

    Hi Good Folks
    I'm using an 800 x 600 output from FCP and trying to get my VGA external monitor to show me the canvas. I have tried all the permutations of A/V device output - here's what happens: my canvas is playing a clip which is 800 x 466 in origin. I moved to the bottom of the screen as needed and when it is not playing back, the image on my external monitor is correctly seen. When I hit playback, it shrinks vertically about 50% or so... can't figure out why! The external monitor is set to 800 x 600. This worked before with a different version of FCP.
    Any advice appreciated!
    John

    Mr. T-Cat
    Thanks for replying. I understand you read and respond to many many posts... I am doing a video art installation in a large gallery and I "map" my video parts onto walls or areas which need to be tweaked with distort parameters or other modifications while in place. I hook up a video projector via VGA to my laptop and finish the video in the gallery. My video projectors work fine at 800 x 600. For video projection 800 x 600 is a standard video resolution. This is a problem with FCS3 as I have used this technique last year w/ FCP6. Motion 4 outputs the correct image and does QT7 & 10. I must have screwed up my sequence settings somehow? I followed another's advice and made an 800 x 600 ProRes422 seq. setting. When I drag a clip into the timeline a pop up window implies that External Video is not optimized, asks Yes or No - advice was No. FCP still says clip doesn't match my sequence settings and crushes the vertical height when playing back even if I drag a full 800 x 600 ProRes clip into my sequence, or say Yes change the seq settings to match.
    Thanks
    btw, I will the program Isadora outputting 3 video streams (AIC @ 800x600) through a Matrox TH2Go into the three projectors each set at 800x600. The Matrox only does a 2400 x 600 output on my MBP thus the resolution.

  • Graphics performance - external monitor

    Hello everybody.
    I've run into a problem..
    When I add an external monitor to my rMBP 15", the graphics performance is reduced by quite a bit. Example: when I play League of Legends on my built in monitor, it runs smoothly at 60fps with almost the highest graphic settings. But when I play it on the external monitor, with the lid closed, it's going at 30fps with the lowest graphic settings.
    Here's the twist..
    I bootcamped it, just to test if there'd be any difference. And surely, there was. Suddenly I could play with the highest graphic settings at 60fps on my external monitor.
    Here's my setup:
    MacBook Pro Retina 15", mid 2012.
    Asus VE278Q
    The monitor is connected with a HDMI cable.

    I have the same hardware, a rMBP with the quad 2.6, 16 gigs of ram and the NVidia 650.  I don't have the problems you are describing but I play different games - mostly borderlands, so perhaps that makes a difference.
    The first thing I would suggest is to use something other than an HDMI cable.  I can't remember the details but I recall reading that the throughput of the HDMI is limited, especially compared to thunderbolt, so I would try switching first.  Of course you are roughly quadripling the pixels you are pushing when you go from 1440x900 (native retina) to 2880x1800 .... so that could be it, and I would also try to scale the external monitor 1440x900 ... and see what happens.
    Lastly, most games run a lot faster under windows than OSX.  Sad but true.  I sometimes run the same game on my server ( a proliant with a Xeon quad @ 3.3 ghz with either a decidedly low end GT630 video card.  It smokes the retina MBP, badly for whichever game I have ever tried. They look better, they run much faster.  That said, I still like to game on the Mac and only use the Server when I need a third machine when my daughter comes to kick my butt.  I personally will take the ease and elegance over the speed, since the rMBP is fast enough.

  • Photoshop color problem on external monitor

    I'm using MacBook w/ OS X Snow Leopard, NEC LCD2490 monitor attached, both displays calibrated.  I found at some point that colors in Photoshop were WAY off on the NEC.  Images looked "correct" in Lightroom on the NEC, but when opened in PS I had massive color shift and desaturation, e.g. purple flowers became dull gray-blue.  I could drag the same image to the laptop and it appeared "correct" in both LR and PS.  I checked color settings, etc. and couldn't find a problem, but presumably that would render the image incorrectly on both monitors.  Most significantly, the image appears "correct" even on the NEC monitor when the laptop display is off (clam shell mode).  Summary:  Dual monitors:  LR/PS correct on laptop display, LR correct on NEC but PS is WAY off.  Using external monitor only:  image displays correctly in both LR/PS.  I suspect this is a hardware/firmware/OS problem vs. PS.  Anybody else have this problem?

    Snow Leopard has some known problems with color managing external monitors.  We've been looking into it and notified Apple (as have a few other color management experts).

  • External monitor "No Signal" message

    MacBookPro mid 2010 with 250GB solid state drive. W80183G9AGZ
    Two problems, they may be related
    Randomly for some time the computer restarts with the message “Your computer has restarted because of a problem”
    This generates a crash report which I always send to Apple.
    (Unfortunately this computer does not support Apple Hardware Test nor Apple Diagnostics).
    Today the computer will not send a signal to the external monitor, ( a Samsung TV).
    I have carried out the following fault finding.
    DVI-HDMI cable plugged and unplugged several times in different order before and after -
    Restart
    Shutdown and then Restart
    Reset PRAM
    Reset SMC
    The same when using a VGA cable.
    With HDMI there is a “No Signal” message, with VGA the screen just stays black.
    Both HDMI and VGA previously worked flawlessly.
    Checked that the GPUs are switching correctly from the integrated Intel HD graphics to the NVIDEA GForce 330M. Previously, as soon as this happened, the external monitor desktop image would appear immediately.
    The presence of the external monitor is not being sensed, in “Displays” in System preferences no second display options are present.
    Questions
    Is the video problem definitely the NVIDEA GPU or could it be the computer crashing problem just getting worse?
    Is it possible to replace the NVIDEA GPU if it is faulty?
    Although the problem seems to be the same with both HDMI and VGA could it still be a problem with the HDMI cable?

  • How many external monitors can I support with 13" rMBP (late 2012)?

    Device has two DisplayPorts and each is powering an external display properly. It also has an HDMI port. Can I connect a third monitor here?

    I got my new 13" Retina in the other day (late 2013 model ME865LL/A)
    I was all excited to see if the two Thunderbolt 2 outputs and the HDMI output would work together, but plugging in the HDMI output knocked out one of the Thunderbolt outputs, so what I read was right, the 13" model will only power two external monitors.  Before I got this I kept reading over and over how it wasn't possible, but that was dealing with the Late '12 or the Early '13 models, I was hoping that the upgraded video card on the newest Haswell versions may be different, but alas, not to be.... 
    But I did implement a work around as I have a Matrox Triple Head 2 Go DP Edition for my old Macbook and what that does is make my two Lenovo 22" widescreens look like one big 3840x1200 monitor to it's host (tricking the MB to thinking "hey, this is one monitor"), so this allows me to use one Thunderbolt output to power these two monitors and then I am using an HDMI --> DVI cable to power an HP 23" widescreen monitor I also have running at full resolution, all this in addition to the Laptop display as well:
    Here is a quick 20 second video of all monitors playing video....   the one on the left in the middle row was staggering but that is more a problem with AMC's website more than anything, I never get good stream speeds from their site

  • 3 external monitors for rMBP - hoping

    I read this article http://www.theverge.com/2012/6/20/3104640/macbook-pro-retina-display-three-exter nal-monitors that declared that rMBP could natively run 3 external monitors (2 thunderbolt, 1 hdmi).
    Mine only runs 2 - either 1 TB and 1 HDMI, or 2 TB. Does this mean something is wrong with my computer, or is there some special trick I need to do?
    Thanks! Mark

    *Update*
    I now have 4 monitors running on my 2009 17" mid-2009 MBP. The MBP, 2 17" Dell monitors and a 24" Dell monitor. Mavericks allows multiple displays as seperate working environments.
    As you can see in the image (excuse the clutter..cable management is under the desk and its a WIP at the moment)I have the upper left monitor working in excel, the middle larger monitor in iTunes, the left monitor is browsing via Firefox and I'm in Safari in this forum on the MBP.
    I have run Photoshop, Protools, Safari and Dreamweaver in this set up over the last few hours also.
    The only issues I'm working through now is trying to have my dock on all displays and keeping the display setting after the MBP is put to sleep. Any suggestions are helpful.
    At this time I haven't put the MBP in my Bookendz docking station, but I just updgraded to a 250GB Samsung SSD, 8GBRAM and replaced the superdrive with the old 500GB HDD. I also store most of my audio and graphic files on an external HDD and iCloud.

  • Connecting Mid 2012 MBPro to External Monitor

    I've recently purchased a Mini Display Port to Display Port cable to connect my Mid 2012 MacBook Pro (Non Retina) to a 23" Asus PA238Q IPS Monitor, when I connect it It displays an image ok, it sometimes flickers but the main problem is it won't display an image in any other resolution other than the MacBook Pros native resolution.
    The main reason I wanted to use an external monitor from time to time is for photography related work and using an IPS Monitor with a resolution of 1920x1080 would be hugely beneficial, not to mention the fact it's 23" not 15"
    Is there a way I can get my MBPro to display the image properly at 1920x1080?
    Huge thanks in advance for any help!

    Can you post a screen shot of your Displays preference pane -> http://support.apple.com/kb/PH4391?
    Should look something like this:

  • Dull/Burry Image on External Monitor

    I connected a MBP (9600M GT) using a DVI-D to HDMI cable to a 24" LCD monitor (1920x1200 native) and am getting a very dull/blurry picture (entire screen - pictures, video, text etc.), but when I connect the same monitor to a windows XP desktop via VGA-VGA with shared graphics I'm getting a crisp picture. Shouldn't I be getting a superior image via the mac with superior cable connection and graphics card? In fact, the picture is so bad from mac that its not worth using. I have tried different resolution settings w/o success. Is there anything else I could do to fix the problem?

    Hi hhog: Are you running the external in Extended Desktop or Mirror mode? If mirror it will not be crisp. To get maximum clarity and detail you need to operate the external monitor in its native resolution (1920X1080). To accomplish that you need to be operating in Extended Desktop mode.
    Hope this helps
