One of the PlayStation 5 barriers is the lack of support for the 1440p (2560x1440) resolution, which is shocking. The list of supported resolutions include 720p, 1080i, 1080p, 2160p (4K UHD), and consequently, 8K. It’s certainly confusing that Sony would skip the 1440p resolution yet support lower resolutions, such as 720p. The PlayStation 5 pushes refresh rates up to 120 Hz in compatible games. Sadly, the PlayStation 5 won’t natively support 1440p, and Sony didn’t explain why or hint if a future update will enable 1440p gaming. One more barrier is that PS5 games are only playable if they’re installed on the SSD. This will be a big problem for those who pick up the Digital Edition since the PlayStation 5’s SSD is only 825GB, and the actual usable space is even less when you factor in the operating system. To tackle this limitation, Sony is currently exploring the prospect of allowing players to store (but mind you, not play) PS5 games on an external USB drive. If that were to happen, Sony would deliver the functionality in a future update. But here’s the kicker: you can store and play PS4 games from a USB drive just fine.
