isn't there an option to have the Pro output 4K, so your TV won't upscale anything? isn't that the whole point of "checkerboard rendering" and such?Yeah, you would think, but the ps4pro UC4 is rendering at 1440p. It's gotta be downsampled to play on any TV (cuz 1440p is not available on TVs). So for me it's downsampling then upscaling I guess. I dunno.
edit:
For those with a 4K display, Uncharted 4’s story can be played on PS4 Pro at 1440p resolution, up from 1080p on PS4. Multiplayer’s fluid, high-framerate gameplay remains the same, but the resolution has also been increased to a full 1080p on PS4 Pro, up from 900p on PS4. The Last of Us Remastered, on the other hand, allows you to choose whether you want to play in the game’s original target framerate of 30 frames per second at 2160p or at a high targeted 60 frames per second at 1800p.
However, those using PS4 Pro with a standard high-definition (1080p) display will also benefit. Both Uncharted 4 and The Last of Us Remastered will render at the highest resolution and downscale the super-sampled image to 1080p, resulting in noticeably crisp and smooth graphics.
