Hello:

1、UH949 (encoder) and UH948 (deserializer) have the following registers set. Can the screen testpattern be displayed? The power on timing of the screen is already correct (the screen can enter self-test mode)

2、This is the screen parameter,Does the configuration of 0x03 to 0x0c 1a to 0x02 comply with the CLK frequency?

3、The following are the registers configured according to the screen specifications parameters,0x1c reads as 0x3b
