I have a Quadro FX1800 video card, i try to output 10-bit color on Display Port,
and also i have a 10bit 1080p video capture to measure it.
My test pattern is 0 to 1023 grayscale, when i wrote a code to test, its range
has some problems, the levels of 1020, 1021, 1022 and 1023 are all mapped to 1020
on my video capture. I also tested the same situation on FX4800, but i got the same
In my case, i use glPixelReads to read frame buffer, and its range is okay.
Please help me to solve its, thanks!
