Hi team, I've had this monitor for a couple months and have been using it at 4k resolution with no issues whatsoever. I rearranged my office and disconnected/reconnected my monitors. When everything was finished, I noticed this monitor is now defaulting to 1080p in Windows. I verified it was the HDMI same cable.

Things I tried:
* Verify it was the same cable
* Disconnect power, HDMI, and reconnect
* Plugged a different computer into DisplayPort and verified 4k works
* Download LG Driver for this monitor and update driver in Windows
* Installed latest Radeon RX 480 Software (v19)
* Searched online
* Bang my head on everything except the monitor
* Update Windows
* Restart many times

How can I get back the 4k resolution on my monitor?

    Oh wow... so it was the same cable, but I had it swapped to the wrong monitor. 

    One cable that I have only works up to 1080p while another works up to 4k :D  I hooked it up to this monitor and everything is normal now.

    Looks like this monitor is very cable sensitive and one of my cables is an older HDMI version.

    mannyfresh, thanks for the update. As you have found the monitor cannot display anything higher that what the HDMI cable provides.
