I see, so this U2412M still has problem with Nvidia graphic cards? All of them?
as long you dont use HDMI or Display Port connectors, youre fine (U2412 only have 1 VGA, DVI and DP)there are ways to fix it though, manually

An Nvidia GTX 780 was used on our test system and we tested both DisplayPort and HDMI – with interesting results. When using either DisplayPort or HDMI the GPU sent out the wrong colour signal (‘Limited Range RGB 16-235’ instead of ‘Full Range RGB 0-255’). This reduced gamma, skewed white point, hugely impacted contrast and simply gave everything a washed out look. We are quite used to seeing this with Nvidia GPUs connected via HDMI as that is their default behaviour – treat the connected device as an HDTV. But we aren’t used to seeing this over DisplayPort which is currently a PC-only output. We tested the ‘MiniDP’ port as well as the full sized DP port using both DP 1.1 and DP 1.2. The screenshot below shows that the native resolution of the monitor (1920 x 1080) is listed under ‘Ultra HD, HD, SD’ as ‘1080p, 1920 x 1080 (native)’ when connected by DisplayPort. This list of resolutions is designed for output in RGB 16-235 to devices such HDTVs.
This can be rectified for both DisplayPort and HDMI by creating a custom resolution with a 59.999Hz refresh rate. This will be treated by any application* as 60Hz but uses the correct Full Range RGB 0-255 colour signal. The process for setting this up is shown in the video below.
*Some games seem to ignore custom resolutions and will instead revert to using the default Limited Range RGB 16-235. That is why a preferred method for correcting the colour signal over HDMI is to use this utility. You just run the .exe file included in the .zip and click the button at the top right which is labelled ‘Set Full Range (0-255)’. You then simply restart your computer. You don’t have to re-run the tool every time the computer starts up, only if you ‘clean install’ a new graphics driver or replace your OS.
Unfortunately this utility doesn’t do anything to the DisplayPort signal. We only had one U2414H with us for testing, but suspect that running them in ‘Surround’ using the MST/Daisy Chain capability of the monitor will use the correct signal as well because the resolution used (5760 x 1080) is PC only. If not a solution would be to use HDMI ports (or DVI ports using a DVI to HDMI cable) on the GPU(s). We simply used the HDMI connection and the utility to correct the colour signal (universally – even for games that ignore custom resolutions) and the difference in gamma, colour depth and contrast compared to an uncorrected signal was remarkable. AMD GPU users don’t have to worry about this and should be able to use DisplayPort or HDMI quite happily.

what made it more than another 1000 bucks more expensive than U2713HM? 
will post with some movies and games screenshots in it 
later will upload some unboxing photo.. poor phone camera though
