I've never been able to get Windows 11 working with four monitors (2x4k at 60 and 120Hz, 2x1080p at 180 and 144Hz) on my ROG RTX 4090, regardless of refresh rate and resolution. When I select "extend desktop to this display" (see https://i.imgur.com/Xq7SmnG.png), it just fails without a message. It works with any three monitors in all configurations. Oddly enough, it works just fine on Ubuntu. Does anyone have any ideas?
Any combination of three monitors works. Whenever I try to add a fourth, it just fails on Windows at least.
