Monitor IDs all wrong: 2-pc monitor and 1-tv

Hi there,

since I got my new GeForce GTX 460 my monitor became monitor number 2 and my tv is now monitor number 1.

Now when switching between screens, by pressing WindowsKey+P on the keyboard, the "Only Computer" icon switches TV screen on and the PC monitor off. When "Only Projector" is selected, it turns my PC monitor on and my TV screen off. Obviously it meant to be vice versa.



Also, when booting my computer, my PC monitor remains OFF until the Win7 login screen. All info is displayed on my TV at which point is off, so I don't see nothing.

When I go to WindowsKey+P and select "Only Projector" my monitor becomes monitor number 1. When switched to the tv only (the "Only Computer" option) the tv is also number 1. When switched to the "Extended" option my PC monitor is 2 and a tv is 1.

It can be very annoying not seeing what's going on when my pc is booting up.

Certain apps display stuff on the screen 1, which usually is the main screen and in my case it is a TV.

Does anybody know what is wrong? I've searched the net and there was few people having the same issue, but I found no fix for it.

I was wondering what is responsible for displaying the booting process on the TV and not on the PC screen.

Can it be bios related? GPU specific property?

Try setting your monitor to "Make this my main display" by doing the following: right-click desktop, choose resolution, should show both your display and your tv. display setting (5th row): (set it to your monitor instead of your TV) you will now see the startup on your monitor.

Multiple displays (4th row): choose "extend desktop to this display" for both monitor and tv if needed.

For Nvidia cards I use "Nvidia control panel" app. found in additional software here:

NVIDIA Control Panel

Additional Driver and software - Download NVIDIA Drivers

Hope this helps.

Hey guys,
I'm still having this problem ever since I installed windows 7. It has nothing to do with graphic drivers, what card you're using, because I had both Nvidia gtx 460, 580 and now ati hd6990. The problem occurs as soon as you connect you tv/amp via HDMI output.

Nvidia control panel and Catalyc Control Center are saying that my monitor is a number 1 and my tv number 2, but this is not the case in windows 7 display settings. It says vice versa. My monitor is a number 2 and my tv is a number 1. My monitor is a projector and my tv is a monitor.

It's not so much an inconvenience, but it is frustrating...

Any ideas anybody?

Start the nVidia Control panel -> Setup Multiple displays....now drag the monitors to the correct orientaion that you want and click "apply" in the lower right corner, the apply/cancel buttons appear after you change a setting on the screen. Hope this helps you.

What bobtran said ought to do the trick for you.

If you're like me, and the actual numbers bug you, uninstall all the monitors except the one you want to be #1 in Device Manager, then unplug them (except for #1, of course). Reboot. Once the computer is running again, plug in the monitor you want to be #2. Then do the same procedure for #3.

You might also look into a program like DisplayFusion, which gives you far more control over such things than Windows does. :)

Right. I'm not sure whether I found a fix or is it a fix just for me, but I recently upgraded my monitor and instead of connecting it via DVI cable I connected it via DisplayPort cable. I usually had my main monitor connected to the first avalable DVI port on my graphics card. This DVI port was the closest to the motherboard. Somebody before told me that it matters. The next 4 ports are miniDP. My TV/AMP was always connected to the second port, first miniDP port, it's connected via miniDP-HDMI adapter. So when I got my new monitor, I connected it to the third port, in my case it is a second miniDP port, at which point I discovered that my TV became a number 2 monitor in display settings and it also becase a "Projector" and my monitor becase a monitor number 1 and a "Monitor".

I've left it like this. I didn't even check if connecting the monitor to the DVI port #1 will change anything, I just left it and it is ok now. Woo-Hoo!

All the above did not do anything to help, but thanks for your suggestions. My suggestion would be to check all your ports on your graphics card.
