Brand new U2414H here connected through HDMI to an NVIDIA card. Latest NVIDIA drivers, Windows 8.1 OS.
Everything seems to work like it should except this strange issue when I can't access any of the OSD controls after the screen goes to "sleep" ("turn off the display after 1 hour"). OSD buttons work no problem from a cold boot (fully powered off screen) and continue to function as long as the screen doesn't go to sleep. i can lock and unlock it without any issue too and adjust settings through DELL Display Manager.
Once I wake it up from sleep with the mouse none of the buttons seem to respond, including Power button. I can press, slide, hold them without any effect until I completely power off the screen by unplugging the power cord. After powering it back on, the buttons work flawlessly.
I've never encountered such behavior before and I'm puzzled what might be causing this. Any suggestions are welcomed.
