Question ASUS VG245 monitor turns on but no inputs work

[bmac98]

I have an Asus VG245 monitor. It turns on fine , and I can change inputs on the screen but both HDMI inputs aren't working. I know my PC works fine because I tested it with another monitor.
It was working fine 2 weeks ago.
Any ideas?

Tried another cable?
