A:AnswerNot natively. PS5 does not (as of July '22) support 1440p, nor does it support 144Hz, and Sony have announced no plans for either. They might get around to 1440p but I doubt it. 144Hz, no chance.
A:AnswerI watched a video on it on YouTube and the guy said that this monitor will allow you to play at 120fps at 1440p so yes you will be able to play this at 120fps at 1440p
A:AnswerYou can, but the quality of the picture is going to be a bit worse. Theyre going to need to fill the extra 1440p pixels by making the 1080p output pixels larger
A:AnswerYes. 1440p 120hz plus monitors are gonna be nice to get decent picture quality and that high refresh rate to compliment the series x. HDMI 2.1 monitors are what's needed to get that 4K 120fps potential and the confirmed one from Acer for example is over $1000.
