OK guys, I need some help or guidance on a projector that I bought:
EMP GP70 Portable 1200 Lumens Full HD LED
As soon as I install my video card graphic drivers, the imagine disappears and I get an "invalid format" error. I have tried changing the resolutions and non of them work. Out of the 5 PCs that I'm using, I only get this error on the PC that needs to use the projector. On the other PCs, it is working normally with all resolution. On the PC that it is not working with, it works until I install the drivers for my HD Radeon 7770.
