Hi there,
I've had a Surface 2 Pro for a month or so. Haven't done anything funky with the display that I know of but recently I noticed some really bad things going on in the dark areas of images on the screen. This is a big deal to me as I use this computer for work in visual effects and photography.
There is severe banding in the dark areas of the image and more worryingly, the display does not seem to be showing any pixels with a brightness darker than 14 out of 255 in the sRGB scale. It just comes out black on the screen. That's 5% of the brightness range gone.
The most basic demonstration of this effect is to go to this page:
http://www.lagom.nl/lcd-test/black.php
For me, all the swatches from 1 to 13, instead of being many shades of grey, are all 100% jet black even with the screen on maximum brightness.
It is certain that the colours are there in the image itself. This can be demonstrated by plugging the signal from the Surface into a separate Dell monitor via HDMI. Presto - you can see all the shades of grey again. But on the screen of the Surface
I've tried fixing the problem by applying different ICC profiles etc. The sRGB IEC61966-2.1 profile gives the best image, but the best image is horrible as described above. There is severe banding when displaying this image (http://www.lagom.nl/lcd-test/gradient.php)
The most interesting fact is this. My workmate also has a Surface 2 Pro, bought months earlier at a different store. I asked him to check his display using the same web pages and he sees exactly the same errors as me. Lots of banding. All greys darker than 14 are crushed to black. Is this a systemic problem with the display driver? A LUT applied by the bios?
Problem might be the same as mentioned here http://www.surfaceforums.net/forum/microsoft-surface-pro-2/7270-recent-update-killed-video-quality.html
I have applied all Microsoft's recommended updates including the most recent one.
Look forward to any tips, hints, fixes, etc. Cheers,
Stuart

Hi again all,
After rebooting my Surface, I noticed that all the banding is gone and my gradients look perfect again.
I believe the problem was that the display driver had crashed and somehow put the display into 16-bit color. Has anyone tried rebooting and checking the gradient again?
Talked to support and tried a bunch of stuff and nothing worked. Am I asking for too much? When I try to watch videos, especially if it's a darker scene I can see the darker pigments trying to figure out what to do. Sometimes even if I pause it these pigments
keep moving around even though the rest is stopped. Really weird. I have a few days left to return my device but I really like it other than this issue. The person at Bestbuy tried convincing me it is normal but I don't think so. Here's a few more examples
of what I am seeing. Again these are screenshots taken using one note so if these look fine to you then I know there is definitely a problem
I am getting the exact same thing. The dark scenes in movies have terrible pixilation. Is this a hardware issue?

I have tried every one of these steps and nothing seems to help at all. I have done all the updates and tried to update my intel(R) HD Graphics Family driver and it says I have the most recent one. It's driver date is 3/7/2014. Version 10.18.10.3496. Is
there really no newer driver after 8 months? Here are a few examples of what it looks like. I took it as a screenshot so it's possible your monitor may not see any problems, I'm not honestly sure how that works.
