What's the display limit on running a screen off USB 3.2 v. 2x2? Concur that 4k x3 isn't the most sensible gaming option for a laptop at present; though I'd be hard pressed to ever go without 4k anymore. I can see why the slide-out option will be falling out of favor soon. Laptop segment is trickle-down from smartphone segment. And the current "new hotness" that smartphones are trying to work out, is folding displays. I think this is where laptops will be headed--although they may not simply "fold flat". Perhaps something like a roller-shade that can be externally plugged into a laptop chassis (sans screen).
