When I connect the PC's VGA output to ADV7441A, the resolution is 1920*1080@60Hz, ADV7441A can't measure it rightly, it thinks the input is YPbPr HD 1080P. When I remove the VGA cable from ADV7441A, then connect the cable to ADV7441A again, it can measure the input rosolution rightly. Why?
I force the firmware to do a double check when ADV7441A thinks the input resolution is HD 1080P at first time, but the second time's measurement is still wrong.
I test this with 3 pcs of different PC(desktop and notebook), my three kinds of LCD monitor can display them rightly, but ADV7441A can't display them rightly.
I program Auto graphics mode to ADV7441A.
Please give me hlep, thanks!
