8. 1440p Monitor, VRR & ALLM Support
Easily one of the most disappointing things revealed shortly before the PS5's release was its lack of 1440p monitor support, reportedly because Sony wants to "prioritise support for TVs."
As gorgeous as the PS5 looks on a shiny 4K TV, a significant number of gamers use 1440p monitors, and given that the Xbox Series X supports them right out of the box, it's certainly a ding against the PS5.
Sony has at least confirmed they're listening to players on the issue, so fingers are crossed they may implement 1440p support in the future by way of a firmware patch.
Elsewhere Sony also needs to enable Variable Refresh Rate (VRR) and Auto Low Latency Mode (ALLM), image-enhancing features designed for HDMI 2.1-compatible TVs.
Both of these features were promised pre-launch yet haven't been made available to date, though much like 1440p support they're likely to be added via a patch.
Even so, given that the Xbox Series X had all of these features ready to go at launch, the PS5 is lagging decidedly in this area.
