Black picture on media player is not black on TV ?

Hell everybody !

I have a strange problem with my GeForce2 MX/MX 400 on Windows 2000:
when I play movies with MS Media player (or BS player) picture is
perfectly okay when it's not dark. But when it's black or dark, I can
see gray squares on TV which sometimes make movie totaly unwatchable.

I'm pretty sure that TV out driver is causing this because picture on
the monitor is okay. I would probably just need to adjust a setting or
two, but I don't know which ones

I'm using latest drivers from nvidia (53.03 from December 2003) and
DirectX 9 on my machine.

Big thnx for any suggestions, best regards and happy new year !

Try full screen video adjustments.

This is in fact normal. Normally your monitor is not gamma adjusted by
the material it plays. Newer cards like the FX5900 and others can in
games, but not generally in 2d. A TV is an automatically gamma tuned
analog device. It does so by a circuit to determine the mid tones of a
picture.

Also NTSC colors are known for their problems in reproducing accurate
colors (NTSC also known as 'Never The Same Color' twice). It's just the
way the standard works. You can try loading an Adobe Gamma profile if
you've got Adobe Gamma Loader from Photoshop and a ICM for your monitor.
This can correct your screen for inconsistencies.

The absolute best solution is to take whatever material you're using and
crop it instead of encoding the black areas (when full screened it will
still play back at the proper aspect ratio) - for example crop a 720x480
DVD to 720x352 or such. The problem is the black gets encoded and all
low frenquency data becomes 'macro-blocked'.
