Lately I've been experimenting with my Sanyo PLV-Z5 projector. I was about to sell it but gave up that idea and I'm pretty sure that was a good decision. I read the online manual and stumbled across the section in the manual that said the Z5 would accept a 1080p input via HDMI. I quickly ordered a 16 foot DVD to HDMI cable to run from the PC to the projector. My question is whether or not there is supposed to be better image quality using a 1080p source or sticking with native 720 resolution. The reason I ask this is because I've been building a budget gaming PC in my bedroom where I use the projector for late night gaming in bed with a 92" wide Grayhawk screen.(Naturally I don't fill the full screen. I use about 60" widescreen) I wouldn't even be asking about whether their is supposed to be a difference in image quality for video sources because it is simple to just use 1080p just in case because framerate is not a issue.. The thing with real-time 3D rendering is that 1080p will require twice the video horsepower to get rendered. I tried out an older game in Unreal 2 and that looked amazing set at 1080p with FSAA and all other filtering like Anisotropic filtering maxed out with an X1950 Pro ATI graphics card.. How does this 1080p compatibility work? When you switch from 720p to 1080p it sure seems like an increase in resolution. To 1080p or not, tis the question.
