Hello,

I have a problem with black level when playing video in MP. I attached 2 screens, which show it (grabbed from 4:3 video and sized-down a bit, side bars black is ok). When playing video in MPC-HC, everything is fine. Codecs used to play are the same in MPC and MP (CCCP), only using "resize" in ffdshow, no other settings are checked. Thanks for any advices.

Try adjusting the brightness for video playback (not desktop) in the ATI catalyst control centre.

I'm having the same issue. Works perfect outside MP. So why should the brightness level be changed in ati?

Make sure you have fullrange 0-255 set under the CCC\Nvidia display settings, this can be controlled by application or the graphics setting, mine are all controlled by the graphics card setting, so get the same visual colours, whichever application I'm running.

This option only appears in the CCC control panel if a HDMI dongle is used with these cards. Otherwise, a contrast/brightness hack is required. I used the AVS HD calibration video available at AVS Forums.

I should mention that I did have the same problem as you back when I was calibrating. However, I do not remember what the cause of the issue was so I can't help .

And where is that under ATI?

What do you mean by a HDMI dongle? I'm just using a std. HDMI cable from my motherboard to the tv.

I have also TV connected using HDMI cable and since new ATI drivers (maybe since 9.1-9.2) the video is no more expanded to full range but in video standard 16-235 range (blacks are grey) and I found no tweak to change it. The only way is to overcome this is to select Color Pixel Format to "RGB 4:4:4 pixel format PC standard (full RGB)" in CCC and on TV you have to select standard 16-235 range - on Samsung TV it's "HDMI black level" option, which must be set to "Normal".

Anyway I would like to expand it back to full range as it would be consistent with other applications. Or it would be nice if ATI drivers would not "double compensate" the range if pixel format RGB 4:4:4 limited range or YBrCr is selected.

WOW this is a big bug in mediaportal !! When the refresh rate changes, blacks are grey !! My TV does not support FULL levels ! When I set CCC to full levels, the screen is very black.. It is not an ATI problem but MediaPortal problem !! It has something to do with the internal refreshrate changer I guess

Most TV's only support 16-235 !!!!

Sometime I do, sometimes I don't...

extra bug: 24HZ => internal RR change sets video card to 60HZ
