The latest computer challenge

Illustration for article titled The latest computer challenge

I’ve installed the 27" HP medical monitor I purchased a few weeks back. I use an HDMI switch to connect my four main computers to my primary monitor, with my old VGA KVM handling the USB connections.

I connected up the gaming rig first, using the GTX 1080 to drive the display. No problem - it easily allowed me to run at the native resolution of 2560x1440. Then I hooked up to the workstation which is running a FirePro W7000 video card. For whatever reason I couldn’t get it to go higher than 1920x1200, the native resolution of the previous monitor.

The W7000 has four DisplayPort connections and nothing else. I noticed that I was going from DP to DVI, then another adapter to go from DVI to HDMI. I simplified that to just one adapter, DP to HDMI. Same problem - can’t go higher than 1920x1200. I tried a different adapter and a different HDMI cable - same problem.

If I go DP to DP, I can get the full, native resolution on the workstation. Yes, it’s a solution, but not an ideal one in my book since I then have to switch inputs on the display instead of the switchbox. I’ve tried updating and reinstalling drivers for the monitor and the video card, but the problem remains. I thought I’d try using a DP-HDMI cable, but as it turns out I don’t have any, much to my surprise. I suspect that, even if I bought such a cable, the problem would remain. I can grab one at Micro Center tomorrow, but I don’t know if it’s worth the hassle.

So, any idea why the W7000 won’t let me run 2560x1440 over HDMI? It doesn’t make a lot of sense that I should be forbidden to do that since HDMI is capable of handling higher resolutions (4K anyone?)

As always, thanks in advance for any insight into this problem.
