I'm trying to use a 4K monitor with a Raspi 4 B rev 1.2, so far I was able to find out that I need to use the pixel doubling in --> Preferences: Raspberry Pi Configuration: Pixel Doubling Once that setting is applied the UI and specially the mouse starts showing some heavy lagging. Is this something...

Try (on the Raspbian Desktop) the following setting:

Preferences: Raspberry Pi Configuration: Pixel Doubling = Enabled?

I've used this setting to be able to see anything but now the mouse is laggy, anyone with the same issue?
