Talking to a Projector
-
Hi! I am trying to figure out how the video card talks to a projector. I am trying to code a small device that will be able to display images on the projector. I plan to expand this project, but before I even begin I need to know how I can talk to the projector. I tried Google, Bing, and CodeProject but couldn't find the answer. I don't necessarily need the code, just a guide, or a paper explaining what happens behind the scenes and what data is exactly sent by the video card. Thanks!

A video card sends exactly the same signals to a projector as it does to a monitor. It could be VGA/SVGA/XGA/**GA or HDMI or component RGB or just about any other video standard (even composite video X| ). A projector, after all, is just a monitor built funny. Cheers, Peter
