BenQ X500i

“Here is the first problem I noticed. Between the BenQ TK700Sti and X500i, those are short throw projectors that will give you around 180"-200" with about the 10 feet of space you have. Unless you want to ceiling mount or place on a coffee table, but you have kids from what I recall, so wall mounting is best which will allow you to adjust the distance to a degree. As far as the X500i, I don't recommend it. It doesn't have enough brightness for gaming. Colors where frequently off. However, it does have great input lag. Out of the box it's a great projector, but after a week or so you'll notice the flaws. Biggest one being color accuracy. The TK700Sti, I owned it some years ago and thought it was great. Also a great gaming projector, but uses a bulb which you'll have to replace and can get dim overtime. I do like BenQs, but I feel there are better options. I've owned about 12 - 15 projectors and the one that gave me the most joy was the Dangbei Mars Pro. The picture is absolutely stunning!!! Great color accuracy and great picture that allows for lights on viewing due to its laser capabilities!!!! You don't need a projector screen at all, but if you do, I can recommend a gray screen that helps with lights on viewing even more for under $50. The Dangbei originally retailed for over $2,000, but with discounts from Amazon, I got mine for $1,200. The dangbei also has MEMC/Frame Interpolation Technology that gives you that extra clear and smooth video play. You're not going to get that from 90% of BenQ projectors. The Dangb Mars Pro also allows blows out any dust collected in the projector with a push of a button from the home screen. Something I've never seen before. Definitely go with the Dangbei Mars Pro and Amazon will give you a 30 day return window if you don't like it. Forgot to mention, the Dangbei is trash as a smart projector, so for the sound and smart capabilities, I have the Roku streambar pro hooked up to mine. Beautiful amazing sound and picture!!!”
