It does turn on, it does go into sleep mode, but it just isn't recognized by either of the computers that I've tried it on.

Is it most likely dead? My setup was dual ASUS VS2248s.

I've tried...
A fresh HDMI cable.

Swapping the HDMI's with the working one.

Uninstalling and reinstalling my graphics drivers.

PC restart, obviously.

Connecting it to my laptop's HDMI out port, same 'not recognized' issue.


The only recent change is that I've started occasionally running a long HDMI to my TV, usually run as three clones. I wouldn't think this would be related.

Possibly noteworthy that I have an Oculus Rift. But it still doesn't work from my laptop HDMI, so at least directly I don't think that it is causing the problem.

In a surprising turn of events, I found a solution. I ran DVI from the graphics card and DVI into the monitor and now it's working.

Perhaps the HDMI port is damaged.

I hope this helps anyone else who runs into a similar issue.

The twists and turns keep coming.

I reinstalled the previously faulty monitor onto the duel stand, and now the other monitor isn't even powering on.

I've tried multiple power cables, including the one that is working on what will hereby be named Monitor 1, the one that wasn't working in my original post.

This isn't making sense.

Can anyone add this up?
