BenQ TH671ST vs BenQ X500i

The BenQ X500i is much more expensive than the BenQ TH671ST, but it also outperforms it in every way. They're short-throw projectors with an identical throw ratio, meaning that they can both be placed at the same distance from the wall or screen. Still, the X500i is a bit brighter, has better contrast, and is more accurate out-of-the-box. The X500i also has more features for gamers and comes with the advanced QS02 dongle, giving it a well-rounded set of streaming/wireless features. In comparison, the TH671ST doesn't come with a dongle and doesn't have any wireless features or a smart OS as a result.
