Hello Bluelions. I have the same monitor and the PS5 and my computer connected. Very good quality and I am extremely satisfied. The resolution is FullHD, not 4k (which needs 3840 / 2160 pixels). At 4.5 kilograms, you can mount this on the wall without any problems. 27 inches is enough for me, as I also have the PS5 connected to the TV (in case I ever want a bigger picture).
For the price, there is nothing to complain about. Hope the information helps you.
