U4919DW, no OSD, blank screen
My Dell U4919DW turns on (white indicator light) and has a blank screen. There is no OSD or ability to press source buttons. Tried unplugging everything and turning all off/on to consistent results. Same problem with Display port and HDMI
-GPU is working, using an old monitor to type this. Windows display setting detects the Dell U4919DW
-Tried new display port cables
-Dell U4919DW doesn't work on second computer, same blank screen (USB upstream works)
-Uninstalled all Intel onboard drivers
-Randomly, the U4919DW does work after an hour or two powered down

U4919DW started working again after a solid hour of power down, then powering up PC, then U4919DW.
Everything functioning well again!Nope. problem is now back. Able to replicate the whole turn off for ages and it works... now just to not turn it off ever again.
