What’s the resolution you associate with PS5 and PS4 games? On the latter, 1080p has generally been the standard, pushing up as high as 4K on the PS4 Pro. And the former format has generally targeted 2160p where possible, with a few noteworthy examples using checkerboard or reconstruction techniques to boost their final image quality.
