Projector cuts out when hooked to laptop

Gateway T-1628 notebook

Specs: Windows Vista
I have a Gateway T-series laptop that when
hooked up to a projector the video cuts out
and keeps refreshing on both the projector and
the laptop after about 15 minutes. I've tried
what I think is everything to adjust resolutions
and refresh rates, but it keeps happening. Is it
the laptop video card getting too hot or
something else? If it is the video card being
too small to run the projector and the laptop,
what would be the best laptop to run
projections without any problems?

If the projector connects via a USB connection...

USB devices may not work correctly when they're connected to certain USB ports e.g. ports in a hub or on the front of a desktop case. If you have a desktop computer, you may have an IRQ sharing problem you need to fix, or your power supply may be starting to fail.
See response 3 in this:

Also - if you are using a USB extension cable, some of them have inadequate wiring and will not work properly with some USB devices.

"Is it the laptop video card getting too hot or

The term CARD is frequently mis-used. If it's something that's built into the mboard, that cannot be removed, IT'S NOT A CARD ! Most laptops, except some much more expensive high end ones, have onboard video - video built into the mboard - it's a video adapter but it's NOT a card !
Most laptop onboard video adapters do not have a separate fan to cool it.
It's a lot more likely your cpu - processor - is overheating.

Make sure you're not obstructing openings in the laptop's base where air enters and leaves the base. It may be a good to elevate the base of the laptop when you're using the projector so there's more more airspace below it.

Check the current cpu temp in the bios Setup when you're having problems with it when the projector is connected.
Tell us what it is.
It that's higher than it should be, you may need to replace the cpu fan, or whatever it's called for your laptop, and/or you may have too much mung - dust, lint, etc. - inside the passages in the laptop's base or in openings near where the air enters and leaves the base.
I haven't looked up many Gateway laptops. You may be able to download a service manual for your model or model series from the Gateway web site, from somewhere related to the support and downloads for your model, which will show you how to open up the base properly, what the fan looks like and where it's located, etc.
