Hi Sir,

My customer try to test HDMI output from ADV7535 bridge in imx8qxp-mek board. We use command "modetest -c" and get log as below

I set mode "56:1920x1080-60" can get color bar in the monitor , but monitor can't show color bar when change resolution to 1280x720-60 or 1024x768-60.

Why we can get EDID modes but can't show color bar?

BSP version : Yocto BSP 4.14.78

monitor: 

DELL -> P2415Q6

ACER -> CB280HK

log :
id encoder status name size (mm) modes encoders
56 0 connected HDMI-A-1 620x340 35 55
modes:
