I purchased the CAC-1010-A (HDCP off) Dual-Link DVI to DisplayPort converter to connect my 30″ Apple Cinema HD Display to my Windows 11 PC which has an Intel Arc A750 graphics card. The monitor connected and is displaying at 1080 x 800 resolution, but it doesn’t provide any options above this (in particular the 2560 x 1600 that I’m wanting to use). The only options available for me are 800 x 600, 1024 x 768, 1280 x 600, 1280 x 720, 1280 x 768, and 1280 x 800.
I have the USB cable connected and confirmed it’s working because I tried unplugging the USB and the display went black. I’ve made sure that everything is up to date through Windows Updates, and tried the Intel Arc Control to manage the resolution, but it just uses the native Windows display management (which I was already using, with the options listed above).
I’ve tried emailing [email protected] about this, but haven’t had any response after two days, so I thought I’d try here too.
If anyone has any suggestions, it would be greatly appreciated.
