single monitor stuck in dual monitor setting

i have only one monitor, and somehow it is being treat as though its the secondary monitor in a dual monitor set up.

i cannot view my start menu, or view any programs being opened, as when i try to open them, they presumeably open on the phantom primary monitor.

even when i try to open display settings, i cannot see the box.

i am able to move my mouse to the left border of the screen and move it off into oblivion, and occasionally drag random folders and short cuts over to view.

if anyone can walk me through how to fix this (im not very good with computers, beyond playing games :( it would be appreciated.

im on my gf's mac right now to write this post, as my pc cant do anything at the moment.

thanks

just wanted to add, when i go into safemode to try to change the settings from there, there is no monitor alternative to choose, and it is stuck in default. ive read here and there, that safe mode is where need to go to change this back to a single monitor, or at least choose your monitor as the primary, but i dont know if there are no options
 

My Computer

why was this moved to graphics card? this has nothing to do with graphics cards. i am unable to open anything on my computer, as it opens on a non existent moniter, as indicated in my OP and post name.

i need advice on how to deactivate the dual monitor function on my comp, not check the registry (which i would be unable to do in my current problem, as it would open on a screen that doesent exist.)

Is the task bar on the bit of the screen you can see?
I will presume so for the sake of this tutorial.
Click on the application you want to move to the part of the screen you can see and make sure it is selected on the task bar (I would recommend Control Panel to fix this problem).
Press alt+space, then press M.
Now use the arrow keys to move that Window from where you can't see it to where you can.
In CP search for 'adjust screen resolution' and click on the appropriate result.
Does it say that you still have 2 monitors connected?
Fiddle around with the settings on this page and post back soon(if possible with a screen shot).

Hope this is of some use.

negative, the task bar is not visible. i have tried the alt+space and M, and then arrow keys, but i have no way of knowing if the box is actually moving towards my view. i am able to right click on the desktop background, and then choose personalize, but when i click on display settings, nothing pops up. im only assuming its appearing on the phantom primary screen. but, no, the task bar unobtainable, unless i randomly click on it when ive put my cursor off the screen

i will attempt the "Adjust Screen Resolution" search, but im worried, that that box will open on the hidden side as well.

thanks for the advice, hope it works :)

i wish there was a hard command to switch monitors. this problem seems like such a simple boneheaded mistake, that there should an easy fix to swap my view...
 

My Computer

Can you right click onto the desktop?

If so, try this...

Right Click > Personalize > Display Settings > Check the box "This is my main monitor." uncheck "Extend desktop onto this monitor."

and do you have an Acer Laptop?


ADD: Try to connect the computer to 2 monitors. and see if you can see your task bar. It seems like this is whats going on...

i do not have two monitors, nor am i using a laptop. the only other comp i have access to in that location, is my GF's mac, which i do not think would be compatible if i tried to have it recognized as the other monitor.

like i said, when i try to open "display settings", it assumedly opens on the phantom other monitor, so i am unable to alter any of the settings.

I'm sure a Mac monitor would work with that computer. A monitor is a monitor. The computer just needs to have the proper jack for it to plug in.

hrm i dont know...im not sure that a Mac laptop would be able to hook into a PC... and what would happen to all my girlfriends laptop contents?

i wish i knew more about computers. i think half of my issue here is in not being able to articulate the problem correctly.

Just as a last resort open up your PC and remove the VGA/DVI connectio to the Mother Board/ GPU temporarily. Try this but make sure your PC is turned off while doing this, please use common sense while doing this.

while i certainly think the way this sounds effective, i have to admit i have no idea what you mean.

this is a bit beyond my skill level. would this initiate some kind of reset for my settings? at this point, should i hand my tower off to a shop for a pro to do up. i have no doubt that someone who actually knows their way around a comp could prolly fix this in a matter of seconds. i was hoping this would be one of those impenetrable obstacles that would end up raising the bar for my personal know-how and experience, but, unless i figure out, at the general arena of search, i think im going to have to pay someone to fixer up.

if your above advice is simpler than im taking it to be (ie somthing a crosseyed baby monkey could do) i think its best if i keep my grubby paws away from my motherboard/GPU/inside of my computer.

This sort of thing really relies on you being cofident enough to take the case off your PC (which can be a challenge in its self) and remove and put back a couple of fairly bulky components.
I will warn you that opening up your PC may void it's waranty if it still has one.
The first time I took a PC apart I couldn't get the floppy drive back in (no big loss really ;) ).

I have been in similar circumstances to you when my laptop's screen shattered, it still recognised it even though nothing ever happened on it; in the end I disected my laptop and unplugged the internal VGA connection; it now runs on my TV.

Depending on how well designed your PC's inerds are it's usually fairly easy to locate the wire that goes from the VGA/DVI ports on the back to the GPU/MB inside.
This DOES NOT require you to remove your GPU/MB just a wire or two connected to it.

So as a round up all you have to do is:
remove case;
trace wire from unused VGA/DVI to source on MB/GPU;
unplug wire,
turn on PC (after putting case back on for safety reasons),
see what happens

please post with any queries before trying this if you intend to do so.

PS Just one last thought, try plugging your current monitor into the othe VGA/DVI port on the back of your PC.

i appreciate the suggestion, but im not altogether sure what the objective would be, let alone what wires go to what.

i think im gonna have to take it into the shop. ive been all through my CP, and any promising leads just seem to open on the other screen (if they are opening at all, even task manager wont open in my view) though there are some boxes that WILL open, like the box to change my wallpaper. i find this strange and suspicious, as though it could all be some virus, but i tend to think all of my comp difficulties are viruses, just in case. i have norton 2010 running, so i honestly dont think its a virus...but you never know.

if i can make heads or tales of what the comp shop people say if/when they fix it, ill try to post it here accurately.

ty for all the support. thanks especially for patience with my grinding inability to articulate anything :o

Hi,

I think the best thing to do would be to download a Linux Live CD. This will show us if it is a problem with the hardware or software/drivers. I would not recommend changing any wires on the inside of you PC. This will not solve the problem, will have a similar effect as putting the VGA cable into the other port, will almost certainly go wrong, and your computer may not boot because severing the link to the primary graphics output will be counted as a serious hardware defect.

EDIT: This will also allow you to back up data if it works, which I assume it will.

Damn why didn't I think of that, thanks Niemiro.
To download a Linux live CD go to Download Ubuntu | Ubuntu and follow the instructions it gives you (if you are doing this on a MacBook the easiest way to do this is to download the the ISO and mount it on your desktop by double clicking on it. Now go into disk utilities and highlight the ISO on the left of the Window, now click the big burn button at the top of the window and follow what it says to do).

Once you have burnt it to a CD, pop it in the drive; go into boot options while your PC is starting up (this varies from PC to PC but is most likely accessed by pressing F8 or delete during startup) and select the Live CD.
You will be faced with some self explanatory screens after the CD loads, YOU DO NOT WANT TO INSTALL but instead just fun Linux from the CD.
After this you will be shown the Linux Live CDs desktop. Search around through the menus at the top until you find something that looks like it will tell you about your systems hardware (sorry this is rather vague haven't used live CD in a while).

Please post back with your results.

@Niemiro just to clarify I did not mean to rewire anything, I simply meant to unplug and replug the connection to make sure it was making complete contact etc. in hind site this sounds like a much better and safer idea though.
When I said " Just one last thought, try plugging your current monitor into the othe VGA/DVI port on the back of your PC." I actually meant on the ports on the back of the PC not the internal connections.

This was moved to graphics card, because a traditional dual montor setup requires a dual monitor graphics card, and for your computer to even have a dual monitor option, you need a dual monitor graphics card (the graphics card with 2 vga/dvi/hdmi/s ports.

hi , if you havnt solved the problem ty this,
boot into safemode, download and install this driver cleaner
Guru3D - Driver Sweeper (Setup) download from Guru3D.com
then uninstall the video card, use the tool and reboot, it should remove the drivers and settings. reboot and reinstall up to date drivers for the card.

Hello oldwing,
If this is still not fixed, can you please provide your system specs for the faulty machine, thanks.
I cant believe we are trying to fix something and we don't even know what it is. :rolleyes:
