I'm currently looking for a projector and have found myself a little overwhelmed with the choices available. There are many options for resolution on the ones I've been looking at. They start at 800x600 and go all the way up to full HD 1920x1080. Obviously, price climbs as resolution increases. I'm thinking 1024x768 or 1280x800 would cover my needs (mostly Powerpoint presentations). Looking through the specs on some of the units, they list a native resolution of 1280x800, but then go on to list that the maximum resolution is 1600x1200. Can anyone explain how this works? I'm used to seeing the native resolution listed for an LCD monitor and you cannot go any higher than this. How do the projectors handle this? Are there any brands to avoid with projectors? I've been looking at Epson and Viewsonic. Newegg seems to have quite a large selection. Are there any other stores/websites I should be looking at? Thanks in advance for any help you may offer!
