| Win7 thinks I have 3 monitors! When I go into the Screen Resolutions (Display Settings) in Win7, and press "Detect", it shows two extra monitors! (see picture below) The second monitor is only 350 pixels high, and I can actually move the cursor from the first monitor, onto the "invisible" monitor if the cursor is within the 350 pixels. Device Manager also shows three monitors...  If I go into Device Manager and "Scan For New Hardware", the screen cuts out and comes back, and now only shows one Monitor! (which also happens when I enter the nVidia Control Panel)  Sometimes when Win7 boots, I get no signal. I have to disconnect and reconnect the DVI cable to get the signal back. Win7 RTM Pro 64bit Benq FP222W 22" LCD, DVI GeForce GTX260 Ive tried five different forcewares, 186.18, 190.38, 190.56, 190.62, even 191.03 beta Ive also tried different Benq monitor drivers, even WindowsUpdate installed newer Benq drivers. I also tried the other DVI port. I also tried WindowsUpdate. It doesn't happen in XP. All to no avail. Whats going on?

| Re: Win7 thinks I have 3 monitors! ...Did some googleing and I think the problem is fixed. I just updated the GTX260 nVidia BIOS from Gigabyte, now it only detects one monitor no matter what I do  VGA BIOS changelog if ur interested.. NVIDIA Source BIOS Version: 62.00.4C.00.01 ECLK/MCLK is 630/1356/1000MHz HYNIX memory over clocking，modify nvclk/hotclk/mclk to 630/1356/1000MHz Fix certain of monitor compatible issue.
