Sharing two monitors off of one RGB output

I have an nVidia PCIe graphics card capable of handling two monitors (one via DVI and one via RGB). I currently have a 17" DVI monitor hooked up, as well as a 15" analog/RGB monitor. I recently purchased a 32" LCD HDTV, which has an input for RGB and can be used as a monitor.

I have three monitors, with only two outputs. The 15" monitor and the 32" TV are in different locations, so I would use them for different things.

To easily switch between the two monitors without losing much quality. I need to be able to output 1366x768 @ 60 Hz to the LCD TV. I don't want to switch the cables to the output all the time. There MUST be some sort of inexpensive switch out there which will accomplish this task.

Though by RGB do you mean SVGA or Composite? You'll need to know which you have before you can get the proper device.

Anyway, what you want is a basic A/B switch, and your best bet at finding one would probably be your local Radio Shack. I would strongly recommend getting one that has manual buttons to push in order to switch outputs.

You could probably also use a KVM switch to do this as well. Just ignoring the keyboard and mouse hookups. Though a KVM switch is likely only to work with SVGA. If you need Composite, you'll have to go to Radio Shack or a similar sort of electronics parts store.

It's an SVGA output.

It wouldn't be VGA, but all of those tend to get lumped under the VGA name.

You'll want to be careful if you're going to be switching between letterbox and widescreen resolutions however. That could have some unintended consequences. There's no way I'm aware of to automatically adjust those, though there are tools that can help make it a bit easier.

Hmm... is it bad that I don't fully understand what you are talking about with regard to widescreen vs. letterbox resolutions?

I figured the video card and software could just figure it out.

As far as 'unintended consequences' - anything permanent??

I don't mean to step in on your thread here, but I think I know what the other post was trying to get at. When you try to send the signal from your computer's SVGA from your monitor which is most like a letterbox format (4:3 ratio) to a wide screen TV (16:8) you would have to go into your graphic settings manually and change your settings every time you switch between the two sources. Or you would have to leave the resolution as the wide screen format on your standard monitor which would not work very well I imagine (unless you already have a wide screen monitor). I don't think you need to worry about any permanent damage, it is more of a matter of convenience. If this is something you are going to use a lot, you may want to consider investing in a different video card, that has an S-video out (or other output compatible with your tv), or perhaps adding a secondary video card to run your TV or second monitor.
