XPS 8700, U2913WM, loss of higher resolution
I have a Windows 10 XPS 8700 desktop which I am trying to survive with until I can get a new Windows 11. In the meantime I may have a dud dual ink cable from my Monitor U2913WM to PC. So whilst waiting on a replacement I thought I'd try the HDMI cable with a USB StarTech external adapter USB32HD2 to see if I can continue to run both my monitors. My other monitor is a S2340L which currently connects in this way just fine. However when I rebooted up the U2913WM is only availbale on 1920x1080 not in its higher resultions which I normally used 2560x1080. Why?
Is this a limitation of the HDMI connection? If so would a different type of connection restore the higher resolution cabaility? I crossed checked that the StarTech is USB 3.0 to Dual HDMI Adapter - 1x 4K 30Hz & 1x 1080p and it says its 4K port supports ultrawide displays up to 2560x1080 (https://www.startech.com/en-gb/audio-video-products/usb32hd2)
Advise please.
Thanks

@redxps630 Thanks.
Any thoughts on how else to get connected at 2560x1080 in the meantime?

A friend just suggested I try another USB 3 slot on my PC. And one works just fine, now back at 2560x1080.
I've no idea why this works! Any ideas?
But at least I can keep working until my replacement DVI cable arrives.
