View Full Version : Video too bright!

Hey all,

First of all, nice to be here, i am glad i finally found this nice forum.

I got a small problem, which is , whenever i try to play any video using WMP11 or Media player classic (my favorite) it is way too bright.

I am running on the following:

1) AMD X2 3800+
2) 2xXFX nVIDIA GeForce 8600GT (SLi mode activated) nVIDIA Forceware 162.18
3) 2GB Kingston RAM
4) Windows XP w/SP2 with latest updates

I read alot about this problem and its a gamma correction issue but it wouldnt work with me cause when i adjust gamma in the color correction tab, it affects all the display, which is not what i am aiming for. i just want the video to run normally not adjust all my display. any ideas?

Sounds like the VMR9 colour range bug. I still don't understand why it has not been fixed after all this time (I first came across it when I had my 9800pro). If you are on windows XP there is an easy way to fix it. Follow the instructions bellow.

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\Contr ol\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

A word to note. The options are backwards (don't ask me why, I don't know) but to get the correct colour range, use 0x3 rather than 0x1.

I've been experiencing similar problems with video playback, and that regedit cleared everything right up. Everything's looking quite fantastic now. :thumbsup:
