“The thing is blazing fast. My chief complaint in the past used to be jittery video rendering, especially 4K “
Your screen can’t display 4k!
“Your screen can’t display 4k!”
True, but even at its native res which is similar to qhd (2560x1440) the rendering is flawless. None of my previous mobile devices were this good. And besides, with a simple usb -c cable you can add a true 4k desktop monitor to the ipad.
That device has a Thunderbolt 4 connector. With that, you can display on most 4k screens now on the market. (Thunderbolt 3 or 4 will accept USB-c cables, and will talk USB-c to whatever device is on the other side.)
A MacBook screen may not be 4K, but the video source may be 4K and rendering it live to a MacBook’s massive pixel count still requires computing power many notebooks don’t have.
