Hi team,

I am use DS90UB954 connect DS90UB913 and DS90UB953.

flashscreen happened when 913 and 953 were switched. I don't know what caused it.

What are the possible causes of this phenomenon?

thanks.

Yes, if your system setting is not correct, it would have flickering issue, some causes:
1. 913 and 953 resolution are same? what is the SOC?
2. the flickering happened just in the switching?
3. pls check the 913/953 sch., and layout. and 954's reg., to check whether it is link design issue. you can visit www.ti.com/fpd-link to get more technical support on how to create one robust link.

you can read the 954 register to check whether error is detected. also you can check the SoC whether it has some error detections, these are helpful to further analysis.

Steven
