[W540] Miracast and WiDI

Hi
I have a laptop Lenovo W540. I installed on it Windows 8.1 and Ubuntu, I have tried to use Miracast and Intel Wireless Display but I cannot find "Add a wireless display" in a Project menu. In addition, AirServer which uses Miracast can't start it.
I have installed the newst drivers from Lenowo website and my laptop is compatibile with the technology. When I run Intel WiDi I only have a window with instruction how to use WiDi.
Where can be a problem?
Solved!

I found a solution. The problem was VirtualBox which uses WiFi card to connect to the internet. When I disabled in WiFi card connection for virtualbox it started work.

W540 - Sound and Display in Linux

Hey dear supporter/user/reader!
After calming down due to the vast loss in quality of the new Lenovo ThinkPads (2.2k€ for such a plastic toy - rly?) I started installing a Debian sid with XFCE d/e. There were a couple of problems to solve, especially this rattly one-click-fits-all clickpad needed a lot of caring and compiling. And not to forget the first two days of my odyssey trying to boot up the machine with my OCZ Vertex 2 SSD installed with any format, partition table protocol or whatever firmware loaded - which was a sobering and vain experience. I ended up taking another SSD from my studio desktop which isn't only half the size but slower, too. 2.2k€ for a machine unable to boot a regular SSD - rly? Whatever, posting my whole snaggling-list would go far beyond the scope of this thread and we all know how capitalism and "consulting" works - so let's look forward.
There are lots of problems left but some of the major ones are:
Bad sound in Linux
Bad color reproduction from the 3k display in Linux
Sound:
In Windows the sound is quite nice. I know that it's a problem of alsa/pulseaudio drivers and that the community has to create appropriate drivers first. But there's no information around by now about the capabilities of the installed sound chip to create some usable workarounds:
Is there a subwoofer built in?
Or other channels/speakers I can route some signals to?
How is this full, brilliant and wide sound achieved in Windows?
Because just using the stereo speakers at the front edge of the notebook sounds really crappy. Routing the signal through an equalizer gets back some of the highs and the "bass" and eliminates some of the bugging mids around 1.5k but it is still far from the sound experience in Windows. And it brings in some problems because I have to setup a dirty workaround via DBus to select different presets in the e/q depending on the selected output device (speakers or headphone jack) which introduces more and more problems with muted channels after plugging a headphone aso.
Display:
The colors look quite okay in Windows, in Linux it's a yellowish-green mess. Since I read about the pretty poor quality of the built-in colorimeter before I ordered this device I didn't buy it in anticipation of the tutorials about using the Windows color profiles in Linux. Unfortunatley copying the profiles from the Windows HDD (C:\WINDOWS\System32\spool\drivers\color) and loading any of them via xicc, xcalib or any other tool handling color profiles does nothing to the color reproduction of the display. I found a profile made by a helpful person somewhere on the internet (notebookcheck? Unfortunately I don't remember) which makes this display kind of usable but it's far from being correct since it introduces a greenish inking at the lower end and a rose red one in the middle of the spectrum. Additionally the overall gamma curve doesn't fit that well. But at least it draws white as white and eliminates the overall lime style of the device.
Résumé:
Maybe I'm just an idiot, too dumb to correctly copy and apply color profiles or to use alsa/pulseaudio the correct way. If so I would be very happy about anyone who would lead me in the right direction. Perhaps someone stumbled over the same problems and has some fixes or at least ideas where to look at. Perhaps someone calibrated his 3k display with a professional colorimeter and is willing to share the results.
If someone is interested in e.g. my Xorg config, the amd64 DEB package for getting a usable clickpad, the slightly working color profile or other informations I'm able to share, please let me know.
Disclaimer:
I can understand if anyone is deterred by this rant in a way that she or he avoids to talk to such a poor goof, but perhaps someone understands my vast disappointment after spending a huge amount of money and a lot of time for a brand which is (was?) well known under (Linux-) enthusiasts for the outstanding build quality, the overwhelming compatibility and the ubergood hardware which was built into ThinkPad machines in the past. I owned, sold, recommended and installed lots of these notebooks before, my own last two machines were two t61p which I would call the peak in quality of this brand. But those times definetly seem to be over.
Thankful for every hint to make this thing more usable, best, Markus.

Here's another profile I stumbled upon. It was made for the T540p shipped with the same display. It is a little more even, so less different colours in the overall grayscale and it has a better gamma curve. But it has an overall greenish touch just like the display without any profile but considerably less.

And to prevent users from searching I upped the profile from my last post to my blog, too:
http://mein-neues-blog.de/files/LEN40B5.icm
BTW I'm actually hacking a GTK application for manipulating the ramps of a LUT profile in realtime since those profiles are not that bad but need a little tweaking to fit my own display.

I just updated my 4S with iOS 8.1.1 and now my screens are not proportioned correctly - just a bit to long and wide. Is there a way to adjust? Or go back to 8.1?

lisan1234,
I am sorry to hear about the screen issues. To clarify, do you only notice the screen proportion difference when in a certain application? By to long or wide are you stating that parts of the screen images are cut off? Please provide details

Tool was resized, buttons huge and wide???

My firefox toolbar and navigation buttons appear 10X larger and wider than normal. As do all internet pages I visit! I tried the zoom in/out option, but that only resizes the pages I visit to smaller font they still appear wider than normal. I tried the right clicking the toolbar and customizing, but once again the buttons still stay much too wide, I'm going crazy, everything looks out of whack all stretched out wide!

Are you using Windows 7 64-bit?
I ask because maybe Lnvolcd.exe is 32-bit (note the date of July 22, 2009) and will not run properly on a 64-bit OS?

Help with colour profiles and wide gamut monitor

Hi there,
I know this issue must crop up a lot due to its confusing nature but I would really appreciate it if someone could explain what settings I should be using in Photoshop to get accurate colours. I had a look around and couldn't find any other discussions that answered this exactly.
My set up is a Dell 2408WFP monitor which is wide-gamut. I have calibrated this using a huey Pro calibrator (therefore have an accurate system colour profile). My photos are in Canon sRGB space, set by Digital Photo Professional (obviously easily changed if need be).
What I would like is to be able to preview what my photos will look like on a standard sRGB display. When I open a photo in Photoshop with all the settings on their default it looks extremely washed out, very low contrast and saturation. This is nothing like what the photos look like outside of Photoshop, and also not what the photos look like on other (normal gamut) displays. I have tried using the "proof colours" settings. When I have "proof setup" set to Internet Standard sRGB the colours look dreadful, oranges become blood-red, definitely not what I am getting when I view the image on a standard monitor. If I have it set to Monitor RGB then I get colours that look like my monitor outside of Photoshop -- this is the closest out of the three to the result I am actually getting on standard gamut displays. However I know it is not accurate because I know my monitor is wide gamut and therefore more has more contrast (and this is the case).
So what combination of photo colour space, proof colour space, and proof colours settings should I be using? My main priority is just the Joe Average using his TN panel monitor on facebook, I accept that on my monitor they will look slightly different. Settings for print don't concern me at the moment.
Thanks for the help. To anyone who will suggest that I read up on colour profiles... I have, and I understand them to an extent, but there are so many variables here that I am getting lost (monitor profile, photo profile, photoshop settings, DPP settings, faststone viewer's settings, browser's lack of awareness...)

You have no idea.
What I'm reading is that you want Photoshop, with its color management enabled, to display your sRGB photos as they would be seen on a true sRGB monitor - i.e., accurately.
Something to always keep in mind, when everything's set right and working properly: Your sRGB image displayed on your wide gamut monitor without color management (e.g., by Internet Explorer) will look bolder and brighter (more color-saturated) than the same image displayed in Photoshop with color-management. There is no getting around this, because the sRGB profile is not equivalent to the monitor profile. Do not expect them to look the same.
It's hard, without being there and seeing what you're seeing, to judge whether your sRGB images are undersaturated compared to what's seen on other monitors. I do know, as one with sRGB monitors myself, that images can look quite vibrant and alive in the sRGB color space.
What we can't know is whether your judgment that your color-managed sRGB images are undersaturated is correct in an absolute sense, or whether you're just feeling the difference between seeing them on your monitor in non-color-managed apps and Photoshop.
Photoshop normally does its color management like this: It combines the information from the color profile in your document with the color profile of the monitor, which it retrieves from a standard place in Windows, and creates a transform used to display the colors.
To have it do this you would NOT want the Proof Colors setting enabled. It is the default behavior.
-Noel
P.S., I don't recall whether DPP is color-managed, but you might consider using Photoshop's raw converter, which definitely shows color-managed output, per the settings I described above.
P.P.S., Your calibrator/profiler should have put the monitor profile in the proper place and set all the proper stuff up in Windows. Is it specifically listed as compatible with the version of Windows you're running?

ThinkPad Twist and WiDi

Can anyone confirm if I purhcase the Twist with i7, Intel HD 4000 and Intel Centrino 2200 BGN WiFi (Not the Lenovo ABGN), I'll be able to use WiDi?
No where in the specs do they mention WiDi at all.

Lightroom and wide monitors

Hi
I just changed monitors and now have a widescreen LCD (a Samsung 215TW). However, images loaded in Lightroom (or Elements) appear too wide and changing width of the application doesn't help. Do I have to run LR in 4:3 mode?
Jay

I use a samsung 244T, everything is fine here -
check your systems display resolution settings, make sure they are displaying at the monitors native resolution, 1680x1050 i believe....

Working with ProRez and wide screen 16x9

So I am trying to edit HD down to SD using ProRez. FinalCut won't let me edit my sequence in real time unless I have it set to 720x480 with the Anamorphic check box clicked. The problem with this is that when I export out to quicktime and open it anywhere the video is now squished because quicktime is not recognizing that it's a wide screen file.
If I make my sequence 853x480 it will export just fine but FCP makes me render every clip to have it play in the time line. Anyone else having an experience like this?
I would love to be able to either edit with Square pixels at 853x480 or just have the widescreen work in 720.

LR and Wide Screen Monitors

Probably a simple question so kindly bear with me on this one. I have the opportunity of picking up a wide screen monitor in the next couple of days at a reasonable price - 19" 1440 x 900. My question, how will LR appear on this size monitor - will it fill the screen or will I experience black banding at the top and bottom? I like the idea of the further width to increase the panels but hate banding even on TV

Hi Alan
I have the Dell 2407 monitor (1920 x 1200) which has the same aspect ratio (1:1.6) as your proposed monitor. I find this monitor "perfect" for LR - it looks like LR was designed with this aspect ratio in mind (consider that most digital cameras have a 1:1.5 aspect ratio).
If you hide the left and right panels then you will only have a small "black band" on the left and right of the image. In all other situations this screen will be well utilized.

AE, ICC color profiles, QuickTime player and wide gamut displays

Hey there!
I was inspired by @AdobeAE 's recent tweet about color management to look further into the subject. We've historically not bothered with it, but are keen to enter the color managed world!
I started in Photoshop, doing tests with working spaces and destination spaces to get my head around how the whole thing works. One thing I quickly gathered was that our Monitors (Eizo S2243W) are wide gamut, which can create problems. For example, if you make an image in the sRGB space in PS, then save it out as a jpeg without embedding the profile, the colours become over-saturated, as any viewing application won't know how to translate the colors. Images created in the Adobe 1998 did not display the same shift when saved 'untagged' - I assume because the gamut of the monitor is closer to Adobe 1998, so even if no transformation occurs the colours are perceptually similar.
For still images all this is fine though, as you can always embed the profile so the viewing app knows how to translate the colours for your particular display.
The problem comes with video. It seems as though it is not possible to embed a color profile with, say, a ProRes QuickTime. If you create a comp in AE using the sRGB colour space, then export the movie you'll potentially have the same over saturated colour problem when viewing the resulting file on a wide gamut display.
So how is one supposed to overcome this, except for turning colour management off?
Any help greatly apprecaited!
Cheers, sCam

Not too many people will be watching your movie on a wide-gamut screen. You'd be better off working in an SRGB mode, if your monitor allows. Colour magement is a poisened chalice, wether you are working with still images or movies. The internet is not colour-managed and everything wide gamut will look oversaturated and garish.

W540 Wireless and Bluetooth for Windows 7 x64 [SOLVED]

I have purchased a W540 with the 'Intel® Dual Band Wireless-AC 7260 (2x2, 802.11ac/a/b/g/n) with Bluetooth® 4.0' option.
As per usual I am doing a fresh install of Windows 7 but I can't figure out how to get bluetooth working?
I've installed the 'Intel Wireless Bluetooth 4.0 Adapter Software for Windows 8 (64-bit), 7 (32-bit, 64-bit) - ThinkPad' (filename giww08ww.exe) however I'm not sure what to do next. I see no bluetooth in device manager or control panel, or icon in the taskbar.
Additionally the device manager shows no misconfigured (!) devices.
What is supposed to happen or where am I supposed to go from here?

Hi,
Installation of hotkeys let you enable Bluetooth through the soft switch. So I doubt hotkey features is something which cannot be avoided.
Nice to hear that your issue got fixed. Please feel free to post back in Lenovo Community Forums if you have any
further query.
Cheers!

Flash and wide-gamut monitors

hello, I'm French, sorry if I write bad English.
there is a big problem flash when displayed on a monitors
"wide gamut".
for example, a photo gallery directed with flash in Adobe
Lightroom, colors are saturated, especially red.
the problem appears in Internet Explorer, this is normal, but
also in Firefox with enabled the management of color profiles.
it seems that the Adobe Flash player is unable to display
exactly colors on monitors types wide-gamut, despite the
calibration of the display and management profiles. ccc in Firefox.
Excuse me for my bad English ;)

up please

15" MBP and Wide Gamut monitor

Does anyone know if the late 2008 MBP 15" (with dual graphics cards) will support one of the newer wide gamut displays at 10 or 12 bits of color?
If not, is it a limitation of this particular hardware, or would any high-end Mac have the same problem.
Thanks
nwmtnguy

Mac users are running wide-gamut displays successfully but there are apparently some tricky issues.

OS X does not yet appear to be savvy about anything above "Millions" of colors. I suspect some update will allow for "Billions" of colors, but that hasn't happened yet.
I don't think that advice really covers it. As I said, Mac users are using those displays already and have written about them. nwmtnguy, I think you would have much better luck with answers if you asked your question on a forum with high-end color Mac users.

C language and 'wide' chars handling crashes

We are internationalizing our product and have run into an issue that I hope someone will have some ideas about. The problem is that when we are using foreign keyboards with our internationalized app, some of the keys (e.g. Cedilla on French keyboard) cause our app to crash. I have debugged the issue to a call to C toupper() and verified that its only an issue with 64 bit opteron (not 32 sparc). Upon doing some research it turns out that towupper() should be used instead to deal with these 'wide' characters. Since changing this and the many libc family calls (e.g. strlen, strcat, strstr, isalpha, isalnum) in our codebase would be a rather large task with some potential unintended side-effects for the stateful returns, we are hoping there is another approach. Anyone out there have any suggestions before I start a mass find & replace & fix.
Thanks,
Mike

Automate an action for tall and wide web images

Can you automate an action to make a web image a certain size whether it's wide or tall? If it's a wide image and I want it 850 pixels isn't a problem but, if it's a tall image and it makes it 850 pixels wide the image gets huge. I need an action to check to see if it's height is bigger than it's width and if so make the height 642 pixels and the auto fill the width and if the image is wider than it is tall, make the width 850 pixels and auto fill the height. I have over 20,000 images I need to convert over for our new web site so if I can automate this it would be a big relief.
Thanks,
Mark

Use the image processor script (under File > Scripts). You'll also need to create a new action which makes the canvas 850 by 850 (with the anchor in the middle) -- choosing your desired canvas extension color. Then just run the image processor script resizing to fit 850 and 850, and be sure to call your newly recorded action to fill out the canvas.
On re-reading your post it looks like you just need to run the image processor script (if you're not looking to fill out the canvases to have images all 850 x 850).
