Dear Sir,
1) Does this noise sparkle? spots flicker on and off?
-> Yes, the noise sparkle.
separately tested R/G/B input signal (4K X2K YCbCr 422):
R range below (228,0,0) : No noise
R range above (228,0,0) to (255, 0,0) : Spot flicking noise occurred
G full range (0,255,0) : No noise
B range below (0,0,228) : No noise
B range above (0,0,228) to (0, 0,255) : Spot flicking noise occurred
3) Can you duplicate this problem on one of our evaluation boards?
-> The customer didn't test this issue via ADI EVB right now. We can lend a set of ADI EVB ADV7619MEBZ to them, but there is not HDMI output interface on the board. It is not able to check the display quality via the EVB directly.
4) Is this image set for deep color?
-> OVERRIDE_DEEP_COLOR_MODE, Addr 68 (HDMI), Address 0x40[6]->0 (default)
DEEP_COLOR_MODE_USER[1:0], Addr 68 (HDMI), Address 0x40[5:4] -> 00 8 bits per channel
Best Regards,
Jane
