Re: Acer Laptop problem with LCD Projectors

I have the same model of Acer and it worked in all of my classroom LCD with powerpoint lectures and with a SONY TV at home. Try right-clicking your screen to view the NVIDIA control panel. Configure "dual" multiple display (costumize to "dual" configuration or "forced-detect."

My laptop is telling me that my Windows Vista program is a counterfeit copy, this laptop is 1 1/2 years old and has worked fine till now

Windows genuine advantage checks the product key from time to time. Usually during an update. There are a lot of false positives reported. If you believe this is the case call microsoft. If you can prove you own the software weather purchased separately or preinstalled with laptop purchase they will fix it.

Make preinstalled vista

If not, the guys who sold yhe pc should install it for you, since a part of the computers price is for the OS, or at least they should provide you a recovery DVD.
