[tde-users] Raspbian Buster resolution problem

Hello all, I've been testing a Raspi 4. Works well with the Raspbian Desktop (it's running Raspbian Buster, latest update, with kernel 5.10.63 and TDE 14.0.12 (PSB). The problem is I can only get 1024x768. I've set the pi to 1920x1080 with raspi-config, then 1920x1080 does appear in Trinity Control Center, but choosing it results in a black screen. All this works with a Pi 3B+ (although I have not updated the distribution). Anyone running TDE on a Pi 4? Thierry
