Now, the monitor can dispaly when the resolution of input is 1024*768 or 720P in the ways of AD9889B HDMI mode.
But it cannot display when the resolution of input is 1280*1024, but I can see someting output in TMDS PINS as 720P with oscilloscope.
So I read some register and find that there is difference about register 0x9E.
when resolution is 1024*768 or 720P, the value of Reg0x9E is 0x12.
when resolution is 1280x1024, the value of Reg0x9E is 0x14, sometimes it will becoming 0x16.
what does this mean ?
Need your help, thanks!
