DS90UB941AS-Q1: How to configure 941 and 928 for HV mode display?

Hi team，

As shown in the block diagram below,
1. When the 941-928-DE Mode screen is on, the screen can work normally at this time, and the register export is shown below. (OK.txt)
2. When the 941-928HV Mode screen is on, the screen cannot work normally at this time, and the register export is shown below. (NG.txt)
3. When I83-927-928 HVMode screen, the screen can work normally at this time.
From the above several tests, it seems that the HV mode screen needs to be configured accordingly when used with the HV mode screen. Any suggestions are appreciated.

Hi Yu,

What is HV Mode and DE Mode? I am not sure what you are referring to.

Hi Michael,

This is the mode of the display. For the HV mode screen, if the HS/VS signal is wrong, it cannot be displayed. DE mode only needs DE signal.

Hi Yu,

I am confused, If the HS/VS signals are wrong the image will not be displayed on the display. Most displays require HS and VS that is correct, Why are you sending it the wrong signals? What does your full system look like? is there a des connected to port 1?

Regards,

Michael W.
