Off topic, but maybe good to know
The recent video driver of Nvidia has a new feature/bug! I have my TFT as well as my PJ attached to DVI connectors. Since I have been upgrading my
video driver I notice crushed video VMR9 levels on my calibrated PJ. My first thought was, ok a bad edited DVD. But, I double checked then with well known flics, unfortunately, same result.
Nvidia mentions a work around for their very cool "new detection feature"
http://download.nvidia.com/Windows/84.2 ... _Notes.pdf--------------------------------------------------------------------------------
Video color-space range for DVI-only1 outputs is erroneously set to standard mode (16-235) instead of extended mode (0-255).
A new detection feature to apply Standard CSC mode to TV outputs (including NTSC, PAL, 480i, and 576i), included DVI-only outputs by mistake.
Note: The driver correctly applies extended mode to analog outputs, and standard mode to TV outputs (including NTSC, PAL, 480i, and 576i).
A future driver release will correct this and apply the extended-mode color space to DVI-only outputs.
You can work around this issue by forcing either standard or extended mode as follows:
1 Launch regedit and determine the current primary display card by looking in
HKey_Local_Machine\Hardware\DeviceMap\Video
and note the GUID (global unique identifier assigned by Windows), which is the long string in brackets { } at the end of the entry "\device\video0".
2 Look in HKey_Local_Machine\SYSTEM\CurrentControlSet\Control\Video\{GUID}\0000 where {GUID} is the number derived from the previous step.
3 Open the "0000" directory and create a new DWORD called VMRCCCSStatus and give it a value of
0x3 - to force use of the standard YUV range of 16-235
0x1 - to force use of the extended YUV range of 0-255
--------------------------------------------------------------------------------------------
So, I did apply VMRCCCSStatus=1 for both DVI heads and after a reboot all went back to full PC-Level range!
