I have a 1920x1080 monitor, if I connect it to a PC, everything looks nice and sharp.
But if I connect it to a laptop (also 1920x1080 internal screen), everything looks slightly blurry, like if every pixel shifted a bit. It happened with multiple laptops.
I also have the left of the external monitor cut off since updating to 6.5, it was fine before. Setting overscan to 40% brings back the panel, but then everything so blurry, it’s uncomfortable to use.
