Interfacing (DSI, CSI, I2C, etc.) • Re: Screen duplication artifacts with DSI interface

I opened this second thread since the first thread is around getting the ICN6211 up and running. Usually forums like to stick to 1 thread = 1 topic so since this more on the panel timings of display, I broke it off.

Thanks for the feedback on the character limit! I've updated it to the following:

Code:

dtoverlay=vc4-kms-dsi-generic,one-lane,clock-frequency=26700000dtparam=hactive=800,hfp=48,hsync=8,hbp=48dtparam=vactive=480,vfp=8,vsync=4,vbp=8dtparam=width-mm=95,height-mm=54
I didn't include vactive originally because the default of 480 is what I need but I've added it now for completeness. Same with color format RGB888 is what I need.

I've played around with the panel timings provided by my supplier:

The best I came up with was close but still some horizontal line artifacts, this was using the maximum values on the horizonal back and front porches.
