OK, so unnecessary and arbitrary restrictions on screen numbers, once again.
There is really no reason you couldn't drive four (or more) lower resolution (4k) screens, given the array of ports.
In case anyone is wondering, the use-case here is a triple-monitor configuration at a desk with a much larger "TV" positioned, or hung, elsewhere in the room.
- wtallis 2y agoUSB PHYs aren't the same thing as display controller IP blocks. It's obviously possible to design a chip with more of the former than latter. At the hardware level, nothing is actually an arbitrarily-subdividible budget of display bandwidth.
- kalleboo 2y agoThe SoC needs to have a hardware display controller for each display, and Apple only put 3 of them on their chip. You can add as many extra displays as you want using DisplayLink which runs as a standard USB device and doesn't use the built-in controllers, but has worse performance, probably good enough for a "TV" though.
