Thank you for your reply, I have a XPS15 with 4K display, it works just fine, and I had some concern about scaling as well. The reason I want a 24 inch is because I personally play a lot of FPS games(csgo pubg), which 24 inch is perfect, and I think 27 or 28 will just be too big for gaming. In terms of scaling, I’ve read through some reviews and they all say the scaling works better than other 4K monitors so I think I can deal with it.
