Switch OLED. Original issue was docking at 480p. Changed pi3usb

Nintendo Questions Switch OLED

Basically. I think I bought some useless pi3usb chips from AliExpress. I’ve connected them all pretty cleanly. No bridges. No shorts. I dock it and get no display. Dock light stays green.

I have a donor board, so might rob that of its pi3usb/P13usb, or put the original back on.

For my original issue though, it only docking at 480p, changing that chip was the right move?

The pi3usb is a muxer chip which is only switching DP signals to USB C. No retimeing/redriving to HDMI. This is done by the docking station as requested by the settings of the Switch.

Did the Switch output FHD before?

It did, yes.

I could reboot and get it docking in 1080 occasionally, but if I put it to sleep, it would never display until I undocked it again.
