The 2013 PS4 Standard cannot do 4K 3840x2160 60Hz. The 2016 PS4 Pro added that 4K ability. The S2722QC will not automatically sense the PS4 and drop its resolution down to 1920x1080 60Hz.
I'm not very computer savvy, so this may be a silly question, but is it possible to connect a PS to a S2722QC monitor? I tried connecting with an HDMI cable, however, the S2722QC failed to recognize any input signal. Not sure if it's relevant, but I typically use my M1, 2020 MacBook Air with my S2722QC.  Thanks!
S2722QC, PS4 connection?
