I have an HP Compaq 6000 Pro All in one desktop computer. I have an older InFocus projector. Now because of the difference in age I had to get a few adaptors in order to try and resolve using the projector for presentations. However two adapters later, I cant seem to make the connection between the two. HELP...I have a Digital port to HDMI connnected to an HDMI to VGA (RGB) that runs from desktop to the projector. Its the only way ive been able to link the two but i cant seem the get it to work. What gives?
