Keep in mind Steam has over 125m (old figure) users . Between native 4K users, Surround users, 1080p/1440 120hz users etc...not to mention those that have their PC connected to their 4K TV's not as a main display, millions already have the capability to drive higher resolutions to a 4K TV.
PS4 Pro is just a 4K upscaler for all intents and purposes.
1800 checkerboard is not 4K. That's like saying 720p/1080i is 1080p.
