Crazy Display

While on my HP Pavilion 6620 F the screen momentarily went blank then the monitor had "No Signal" for about 2 seconds then everything came back but at a different display size. Going to settings and resolution it now has only 3 choices and it gave me 1024 X 768 (Recommended). That's way bigger than normal for my 22" monitor. Changing it doesn't work out either. It's either much bigger or smaller. I've done all windows updates, checked for updates on my video card VIA the device manager. What I did do to get it back for a short time (1 hour) was to do a system restore. When it failed again, I did another system restore and it failed in about 20 seconds. Everything is there on the screen but just much larger (wider only). Am I losing my video card or missing something else? I've also ran System Mechanic, Malwarebytes and windows defender all to no avail.

I've tried that. This is what happens: I go to the location for HP Video check and when I click on it I get a pop up saying "This app has been blocked for your protection" "An administrator has blocked you from running this app, for more information contact the administrator." The thing is I am the administrator. Clicking on the properties for the video check and giving myself full control under the security tab makes no difference. Who, in this case, is the administrator that's stopping me? I really think I got hit with some malware or a virus and I don't know how to get rid of it.

From the device manager, I do have the latest drivers. From HP, even as administrator it says I'm blocked by another administrator. HP sends me to the HP support assistant which still won't let me download anything because it's blocked. I even restarted and signed on as administrator and tried it that way. It doesn't block me but it just says it doesn't work. I have no clue other than I have a virus and I can't find it nor get it out.

Hey friend.

Looks like everyone is having this exact same problem. It happened to me too.

The fix is simple, just roll back drivers in device manager for the Display Adapter

Where the block is for rolling back the drivers, it's not backlit. It's only written faintly in the background. Under driver details it says no driver files are required or have been loaded. Should I disable the device? It's ATI Radeon HD 4200.

What I can say for sure is I had this problem at 7:30 this morning and it took me until 3 PM to figure this out. I must have deleted/uninstalled the device 3-4 x throughout the day. So try it.

I think the other poster is right, you need administrator privileges. At least try uninstalling the display adapter and restarting the system, then look to see if it's no longer greyed out. Good luck.

Right now the adapter is disabled. Restarted and no change. I'm willing to try to uninstalling it but if that doesn't work, can it be reinstalled and if so, how?

Well in my experience Windows will assign a generic name to the device when it boots after the driver is uninstalled or sometimes it just reappears as its same name. You can rest assured it will still be there, hopefully. It will probably automatically reinstall the same driver protocol as before until you mange to roll it back.

There's a AMD utility as well that cleans all their software off your computer. Forget what it's called but it should be in the AMD or ATI program file if you have one. Use that, delete the drivers, uninstall the device, etc. The main thing is to figure out how to click that roll back button.
