Quoted from Drenden:Because you aren’t going to get 4K resolution or graphics out of the onboard video on the motherboard and they aren’t going to put a $600 gpu in each game which are now impossible to get. 4K gaming is still very expensive in the pc world and you’re not going to see the difference on the types of animations on pinball machines anyway.
Also the smallest digital signage platform in 4K is 40” because of pixel density.
I didn't understand the comment this was replying to. Is there an expectation that pinball displays should be 4k? This makes no sense due to the size of the display, and how far away you are, and the fact that nobody spends much time looking at it.
Now the P3 games - I do think they would benefit from the playfield display being 4K. I'd definitely upgrade if they provided one. Even better, an OLED display! (even at 1080p that would be incredible) For 4k even that display is quite small
