Dreams in Digital
At 5 feet away from a 4K TV, the difference in Horizon: Zero Dawn and Days Gone was stunning. At 10 feet, they still looked noticeably better. Admittedly, I have 20/20 eyesight and review products for a living, but it was enough to make me consider trading in my existing PS4 for a PS4 Pro.
And even on a standard HDTV, one with a 1920x1080p resolution, the checkerboard technique (combined with supersampling, where a game is rendered at a higher resolution and then shrunk down to a lower one) greatly improved the quality. Lara Croft's hair, and the tree branches around her, didn't shimmer nearly as much. Old PS4 games looked like they'd been remastered once checkerboard rendering and supersampling were turned on.
