So I just received my new monitor today. It powers on, is detected by computer but nothing displays. I can see the backlight so I know its on but it displays nothing. Even the OSD menu doesn't display.
List of things I've done so far:
Tested several Displayport Cables -fail
Tested 2 different HDMI cables -failed. All cables work fine on my other 2 monitors
Tried a different PC - failed
Tried different ports on GPU- failed
Downloaded monitor drivers and installed
Physical inspection - No sign of damage to screen or packaging
Purchased brand new.
It cost me a small fortune ($400+) and a whole month to ship it here so unless someone's paying, sending it back is not on my list of options.
Any help would be appreciated. Maybe something I missed?

Confirmed. Light is Orange once no signal from PC.
Once PC is turned on, Light is White. Monitor is detected by windows and even shows up in display settings. Only issue is nothing displays.
Monitor is directly connected to GPU. no adapters. I have tried both HDMI and DisplayPort cables.
Pressing the menu buttons on the monitor shows nothing either. :(

Any updates on this?
I've had mine for a little over 6 months now and today I got the exact problem you're having.

Unfortunately no from my end. I've been told to return it for repair, but it would cost me more than the monitor just to ship. So it's pretty much money out the window for me. Sadly.

Bumping this in case anyone else has any info. This just happened to me today. Windows is able to identify the monitor and you can see the backlight but no picture. Really annoying that this monitor died after only 3 years.
