There are four things you need to know about the BenQ TH535 right off the bat. First, it's a DLP projector that costs just £500. Second, while pitched as a home entertainment projector, it's also got a Presentation preset. Third, it's a Full HD model with no 4K or HDR capabilities. And, finally, it's really bright – a claimed 3,500 Lumens bright, to be precise.
