Question BenQ HDMI 1080p monitor shows as a "digital display" connected via DVI and only goes up to 768p in the settings

Kinda a mouthful for the title, but originally one of my monitors which is a GL2250 wasn't working at all yesterday. I managed to get it working and now in Windows I can't changed the res above 768p despite it being a 1080p monitor. In Nvidia Control Panel it doesn't have a name for it, only "Digital Display". It also says its connected via DVI despite it being HDMI connected fully and the resolution goes no higher than 768p.

I've tried swapping power cables and HDMI cables around to no avail. My other BenQ monitor works completely fine still.
