Screen Resolution Help

renthor · 02 Jan 2009

Ok, something's gone wrong with my Windows 7. I was playing a game in window mode, told it to go full screen. The game worked, played it for a little bit, then I quit. Now my screen will not go back to the windows desktop, it just stays black.

I tried safe mode and system restore and cannot get it to work. I know windows is still working because I can hear the logon sound when it starts up, just a black screen. The monitor never shuts off or goes into standby mode, it just stays black - no cursor even, so I don't think its activation related.

Can someone please do me a huge favor and figure out what the key strokes are to change the screen resolution? My plan is to right-click and then go from there with the keyboard. Maybe changing the resolution to anything else will force it out of whatever mode it is currently stuck in.

Thanks in advance.

Right click on Desktop, press letter C, then hold ALT key and press letter R, then up and down arrows move the resolution up and down - I assume you want to take it to the top resolution allowed, especially if you are using LCDs, because Windows has a good habit of *usually* limiting resolutions to what your monitor can handle....

Any other things you need?

Also, have you tried a different monitor? Perhaps the game that you played stressed the monitor out and eventually broke it when you quit....

An alternate video card would be handy to test as well...

Finally, the default checking all connections and making sure the card is seated properly (make sure to do this when the computer is off) is a requisite for troubleshooting this issue as well...

Hm, thanks for the instructions, but they don't appear to do anything for me. The screen doesn't flicker or even so much as register that I've made a resolution change. Usually when I do something like that my screen will go into "auto-config" mode and adjust itself.

Acer AL2016W if that helps.

And I know it is not the screen or graphics card because I dual-boot with Vista, and I am currently using that right now to post this.

Is there anything I can try in safe mode? I tried changing the resolution from there, but that only effects the current session's resolution, not your normal resolution.. hmmm

You *could* try driver sweeper in Safe Mode and ...

feh - you have to install it first and then load it ins safe mode....

I haven't installed it yet here, though, and since the box seems to be working, I suspect it may not be a "resolution" issue so much as a refresh rate issue. If that is the case, we have two options - I can try to guide you through setting the refresh rate back to 59/60 or I can try to walk you through installing Driver Sweeper so that once it is installed, you can go into safe mode and wipe your video card drivers out....

I suggest we try refresh rate first.

Ok, yeah refresh rate sounds the easiest, hopefully. Installing programs on a blank screen just does not sound fun at all. 60 will probably be the best bet, I've tried 59 other times and I get hit or miss results with that.

If this doesn't work, do you think just uninstalling or rolling back the driver in safe mode would work? Might not be as clean as driver sweeper, but I could always install and run that if it got my screen to come back up.

Unfortunately, I am having to find an alternate method as the Advanced properties is only opening via a link at this moment....

I may have found *how* to get to it, but there is a larger problem - the box will have numerous listings and may still cause you problems.

Let's try it though - I suspect I can get ti working in a couple of steps:

Right click
press C
press the Tab key *6* times
hit the Space Bar
hold ALT and press L
use the up arrow *twice* - hopefully that should get to a resolution that will be usable
press ENTER
press Alt A - if the screen flickers, press the left arrow then press Space bar

if the screen is viewable, you can exit out - if not, repeat starting with Step 5.

If you do the up arrow only once, then it may not catch it, as I suspect the system is still looking for another ALT key combination....and if you use the *down* arrow, then it will take 3 to four presses to actually move the selection box - hence the up arrow is the best way to go

I'm wondering if there isn't something else going on, because nothing I seem to try is working. The monitor still isn't even registering that I'm trying to change any settings.

Unfortunately at this point I think I'll have to reinstall Windows. Unless you or anyone else can think of something else to try.

Thank you though for all of your help.

To me it sounds like the game has hijacked your display settings and is now not allowing you to fix it. Let me try to install Driver Sweeper and see if it is relatively easy to install - because Driver Sweeper works in Safe Mode, at the very least you'll be able to get rid of your graphics accelerator's driver and that will force W7 to load a default (and ugly looking) VGA driver and from there you should be able to reinstall your driver.

BTW - what game?

johngalt · 02 Jan 2009

UPDATE - I had forgotten about this - they have the pure binaries available so you don't have to install it - is you run Safe mode with Networking support, then you should be able to download and extract and run DS from directly within Safe Mode....

THANK YOU! This did the trick. Running Win7 right now. Now just to reinstall the drivers.

Again, thanks. Saved me from a new install..Oh, and the game was Doom.
