A:AnswerHDMI 2.0 is adequate for 1080p 120fps it probably would work well with the ps5 and that’s what I’m buying it for unless it doesn’t have an HDMI 2.0 port
A:AnswerYes this monitor works for the ps4, although i wouldn't recommend this monitor as this is a 1080p 144Hz monitor getting a 60Hz monitor would do you more good in price.
A:AnswerWhich monitor you choose will depend on what your needs are and the features you are looking for. Please see the link to compare available specifications for both units. ^Daphane https://www.lg.com/us/compare?bizType=B2C
A:AnswerA standard Display Port cable will work for any Display Port configuration including the new capabilities enabled by Display Port 1.2- 4K and multi-stream capabilities. All standard Display Port cables support RBR, HBR (High Bit Rate), and HBR2 (High Bit Rate 2), which can support 4K at 60Hz, or up to four 1080p displays using multi-stream. ^Daphane
A:AnswerThis can mount. I have mine mounted. You have to take off the back plate off though. I also had to use different screws for my mount. And to answer the second question, it should work but you can’t take it to its max potential. It will be stuck at 60hz.
