Windows 10: 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.

Crazy turn around with Lumia 930 display

Yep, see if it settles, but I wouldn't hesitate to bring it back if needed.

Good luck with your new 930!

 

Press the Win key+X and choose Device Manager. Expand Display, if there is a yellow flag next to the Video device, or if it has the Microsoft Default driver, then you need to download a driver
Go to the HP Drivers site. HP Software and Driver Downloads for HP Printers, Laptops, Desktops and More | HP® Customer Support Type in your Full Model #, (ie) Pavilion 6620 Fxxx Choose your Windows 10 version (ie) 32bit or 64bit, and download the Display/Video driver for your computer.

 

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.

 

No one said to go to HP Video check?!
Follow the instructions in Post #2 and download the driver.
The driver downloads as a Zipped file, when you click on it, it unzips to C:\swsetup\ or some such, take note of where it unzips. If the Driver fails to install, browse to this folder, open it and Right click Setup.exe and choose to Run As Administrator. If the driver is for an older version of Windows, (ie) Windows 7 then Right click Setup.exe choose Properties/Compatibility and make it compatible with that OS.

 

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.

 

I just spent 3 days trying to fix this exact issue on my wife;s HP.

It's the latest WIn 10 update that's erased your old driver and is preventing you from rolling back/updating it.

Once we rolled back Win to the last version, we had no problem getting it to reinstall the proper Radeon driver instead of their generic PnP driver

 

This problem started on 11/23. I've done a system restore back to 11/24 (earliest it will let me). No help. I have no updates to windows between 9/13 to 11/24. Still can't get things to work. Noticed also that when I go to start/power-there are now only two choices. The sleep is missing. Still can't get to the Radeon driver to turn it back. That option just isn't there to click on. (It's there in the background though) I'm at a loss.

 

Dach, first thing, go to HP website, download your Software/Driver as a Save, remember what SP number it is. in device manager, uninstall it there, then in Programs and Features, uninstall it there. reboot, after it settles down from doing what ever it does.. go to your download folder, and open the files, follow the directions, then after it finishes, you might have to reboot again.
