@mitu Have never tried it, but as boot/config.txt options can be set per display-port (0/1) and at least if kms is used instead of fkms display_hdmi_rotate should be worth a try - but I am not sure what's nowadays status is in regards of retropie & kms as the video driver.

@hopwon said in Using official RP 5" DTS IPS Screen for hotkeys, box art etc.:

My question do you think the RPi4 handle the additional screen?

Yes, it should work fine.

Not looking like it from what I can find, I'll have to go with the autodetect on boot script, that will have to be good enough.
