I have an old Proxima Lightbook LB 20 projector. The projector works fine but when I connect the projector to a Windows 7 laptop with a VGA cable, I get an error message on the laptop saying something like: "cannot connect to the projector - no projector detected"

Does anyone have any ideas for connecting this projector? Do I need a "legacy" video driver? Is it possible to make this work? Are there alternatives or workarounds to use this projector with a laptop?
Any advice is greatly appreciated.

While this should work, it's more likely that the video board may be bad on that projector. By the looks of it, that projector could be 15+ years old and is worth well under $50. It's just not up to the task anymore and not worth spending ten minutes trying to make it work.

There are projectors which sell for $100 on eBay which are terrible, but still much better than that.

If it was working, then great, but if it's not, then don't bother. Look elsewhere for a projection solution. There are some great options out there.

The projector displays on the wall just fine. The menus display on the wall, etc. It's only the connection to the laptop that is not working. I was thinking that it was a problem with Windows 7 not having the correct driver to recognize that projector.

Generally speaking, computers don't need drivers to utilize a VGA connection. VGA is not a data connection which needs drivers like USB is. VGA is a video connection. It carries standard video signals across it. This means that every VGA device in the world should work with every single VGA display in the world as long as the source supports the resolution of the display.

Most displays use very standard resolutions, including the one you have.

If the rest of it works, then check the menus to ensure the VGA connection is set for a computer input. Try a different computer if you can. Some computers only will allow a connection if proper EDID is shown. There are ways on laptops and computers to force certain resolutions to be used on the output, regardless of whether or not the laptop claims to see a display connected to it.

I haven't run into this type of issue in the past, but some laptops require a bit of work to get them to do what they are supposed to do automatically.

If using a laptop - Right click on the desktop, then click 'screen resoltuion'. A page will come up and it should say 'connect to a proejctor'. It should have a pop-up that allows you to choose 'Duplicate' or 'Extend' - I would choose 'Extend' - but you can pick either one.

Now the laptop is putting out video through the VGA port.

If you don't see it on screen, and you are sure the projector is on the VGA connection, then the VGA input on the projector may be broken.

Try a different source, and try a different VGA cable to confirm.

Thank you very much for the advice. I think I will take your first advice and buy a newer projector. Maybe I will find a deal at the Black Friday sales coming up soon.
