I am sorry to hear about this. Have you tried a different display port cable?
Are you able to try a different device connected to the display port? Do the HDMI ports work correctly? Have you tried a factory reset on the monitor?
I tried pluging my laptop. No joy with the DP. But both HDMIs work fine. But they only give 30hz refresh rate even with HDMI 2 cable. I reseted setting from the menu but not sure if I did factory reset. How is it done?
Please send the full model and serial numbers to this PM Link.
