Dual Monitor Problem on Windows 7

My pc is running windows 7 with nvidia geforce gt220 video card at dual monitor mode with extended display.

I have an LCD monitor (primary) connected to the dvi output and an LCD TV (secondary) connected to the vga output.

I turn the LCD TV off and turn it back on, it automatically switches to single monitor with the LCD monitor disabled. When I open the "Screen Resolution" at the control panel, only 1 display is detected (the LCD TV). But when I open the nvidia control panel (without doing anything else), the LCD monitor is automatically enabled and set back as the primary monitor.

How can I fix this?

Yes, I have the latest driver installed.

If you turn off the LCD TV it should be indeed going to 1 screen. When you turn the LCD TV on again (after a few minutes) will the system detects the LCD TV?

Yes, it did detect the LCD TV. But it disables the LCD monitor. I would have to open the nvidia control panel and it would return to both displays without changing anything.

Also, I'm not really sure it detected that it was turned off. The screen resolution page still shows 2 displays and the monitor is still extended.

And there is now option in the nvidia control panel to 'remember' the setting?

Maybe you can try a Vista driver. This may could help.

It uses the same driver (installer) for both win 7 and vista

Try an older version to see if it's helping. It can be a bug in the drivers.
