I have 2 Toshiba Sat Pro A120 laptops here and they've both developed a similar problem with projectors.
The one doesn't seem to have any VGA output at all, I've tried every display setting I can find, updated drivers and different cables. I tested the projector on my laptop and it's fine. I've tried the A120 on other projectors and it doesn't work at all. It doesn't even display the boot-up screens, so I reckon it's a hardware issue...Any thoughts on that?
The second one is a bit more of a puzzle. It doesn't display on a specific projector (the one the teacher uses most often). As far as I can see there's nothing wrong with the settings, and when I took it to a different projector it works fine. My laptop also works fine on the said projector. It appears the projector and laptop just don't get along! Any ideas?
