Lost all video after mistakenly selecting second monitor

Hello Eight Forums:


I'm in dire straits here. I have a Dell Venue 8 Pro (Tablet) with Windows 8.1. I was trying to get my Widi to interact with my TV so I could stream a movie...and it was not communicating. So like the knuckle head that I am...I started choosing each display option (dual monitors, extended display and then second monitor only). Well, when I selected "second Monitor only" and since I had no second monitor to extend to...I completely lost video functionality...now I can't tell if my tablet is on, off, what screen it is on, etc. I don't even know if it is working. I tried all the function keys with a wireless keyboard that I have, tried control/alt/delete to reboot, tried to turn off and reboot but nothing...can't even tell if its on or off. This all started last evening. I plugged in to charge overnight and hoped maybe it would reset or something...but no dice. Same thing now. At one point last night after I lost video functionality and after pressing way too many buttons on the keyboard...I did hear some commands coming from the speaker like some sort of disability assist but then it went away and I have nothing again. I was hoping there would be a key combination like FN F4 or something I could press to toggle back to PC only. I tried the Windows button and P....but nothing happened. Any help would greatly be appreciated. Thanks.

Hi there 'dgskas1', welcome to Windows EightForums!

Try:
:winkey: + p + down arrow then press Enter and wait a few seconds;
if you get nothing, do it again til you get your screen back.
