Screen door isn't totally a resolution issue.
You can affect SDE good or bad based on pixel density, which I believe the consumer release versions improved on this part and was a focus. Each pixel can fill with a color, but there is a black (screen door) grid around each pixel as well. If you make the pixels larger and the black space smaller on the panel, that also reduces SDE considerably.
Another possibility is 4k or in general higher rez panels but running games at lower rez on those panels to maintain needed performance. If you have a quality scaler you can have say 1080p rez running in a 4k panel. You can do that today with whatever monitor as well, you don't have to run at native resolution. The problem with running lower rez than native on most monitors is the scalers built in those suck and blow and blurriness happens. But common thinking is 4k panels need 4k rez games which means gobs of power to maintain performance. You could have 4k panels to reduce screen door and run say something like 1080P or 1440P rez games on those panels to keep frames high, if you have quality scaling.
So scalers and pixel density are ways around SDE. Razer's VR unit they are using a pixel blending technique to further reduce SDE.
