A:AnswerIt will work great. I tired it on my ps5 and on my Pc. It works great with dp port really. Due to hdmi only pushing 60hz with 1080p only because hdmi can’t handle it.
A:AnswerIt depends on which PS4 you own. If you own the original PS4, then it will downscale to 1080p since that is the max resolution supported. If you own the PS4 Pro, then it will support the full resolution of the monitor (2560x1440p).
