Hello, & Welcome to Tom's Hardware!
Yes your monitor will work with Win-7. It's max resolution is 1280x1024 4:3 aspect ratio. It has a VGA plug on it, so if you use the same video card you are using, no problem. If you upgrade to a higher end video card that has doesn't have the VGA adapter on it, you may have to purchase for a couple dollars a DVI to VGA adapter plug. Most modern cards have both VGA and DVI, possibly an HDMI plug on the back.
