I already have a decent surround sound system in the room, but I probably will use the screen money for better seating. ...power went off again... Watched ALADDIN and WATCHMEN last night, and I have to say I enjoyed seeing ALADDIN more on a big screen. Little things about the animation really stand out, and the escape scene from the cave of wonders was a lot of fun to watch. One thing I haven't done yet, and I don't know why, is play some video games using the projector. Unfortunately, with the power out, it doesn't look like I'll be doing that today. It's a good the the Virtual Boy can run off of batteries.
Check with the manufacturer or online FAQs regarding your unit; it is all digital, so there should be LESS of a chance of this, but the issue with older style projectors and video games is that the persistent elements of the interface (the HUD, the score, the lifebar, whatever) may result in screen-burn-in, where they permanently leave a ghost impression.
