(which is the general-purpose solution), or to
ATI CCC: pixel format: RGB 4:4:4 (Full RGB)
madvr: RGB output leves: TV levels (16-235)
(which is probably the preferred solution if you care only about your videos displaying correctly - be warned: anything other than madVR will display incorrectly, with clipped colors).

In your current setup, madVR squeezes the 0-255 RGB data into the 16-235 range, and later, your video driver squeezes that 16-235 data, which it thinks is 0-255 data, into 16-235 again!
The only way to get the tv to display this jpg picture below correctly is to set pixel format 4:4:4 limited (16-235). So I dont think Full RGB is correct for desktop usage either.


If the pixel format in CCC is 4:4:4 full (0-255) I only see 14 of the black boxes. When pixel format in CCC is 4:4:4 limited (16-235) I see atleast 27 boxes

Also using totalmedia theater i can see 17-25 in the calibration video flash when CCC is set to pixel format limited.. If I set CCC to full pixel format I see no flashing in the calibration video.

And with CCC pixel format set to limited and madvr to tv 16-235 I can also see the blinking. If CCC pixel format is set to limited and madvr to pc 0-255 I cannot see the blinking.

Therefore I conclude that the following must be correct fort the VT50 using a hdmi cable from the 280x:

ATI CCC: pixel format: RGB 4:4:4 (Limited RGB)
ATI CCC: Video: Dymanic range not selected
LAV Video Decoder: RGB output leves: untouched
madvr: RGB output leves: TV levels (16-235)
