If it works on VGA then what is the benefit in HDMI? Projectors don't tend to have high resolution, particularly ones that are old enough to be out of warranty. I was under the impression that quality at high resolution was the main benefit that people get from using HDMI? From my own experience using projectors it seems very rare to have any quality problems that aren't directly related to low resolution, poor focus, ambient light, or a poor projection surface. As an aside I've finally got DVI working. After years of using VGA to drive monitors which are DVI capable and a couple of months of owning a monitor which can only be driven at full resolution with DVI or HDMI I have finally bought a video card that has DVI (I got the silent 5450 - thanks Craig and others). It took me a couple of months because 2048*something on my 2560*1440 monitor looked so much better than anything I'd experienced that I didn't feel an immediate need to make it even better. As an aside, I've seen adverts for a digital video camera with a built in projector. Has anyone tried one of them? Obviously such a projector wouldn't compare to the quality you get from something attached to the ceiling. But I was wondering if you could put a VGA resolution video on one of those and project it such that text is readable. Technically it shouldn't be that difficult to make a VGA resolution video of lecture slides and then use pause/play to control moving between slides. This could be used as a backup for when we have problems with something like a LUV meeting and also for informal talks. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/
