This is a used Sharp PG-F310X Projector is a XGA Projector. It's in good working order, but has not seen much use lately, so we're selling it. I just let it run for an hour to make sure it's still performing well, see third image. This lamp based projector is capable of displaying 3,000 Lumens at its brightest setting with a native resolution of 1024x768 . The internal DLP technology touts higher contrast, less visible pixels and more portability.
