BenQ X500i vs BenQ TK700ST 4K Short Throw Projector

Both are 4K DLP short-throw gaming projectors from BenQ, but they solve different problems. The X500i uses a 4LED light source rated up to 30,000 hours, covers 84% of DCI-P3, and reaches 4.2 ms input lag at 1080p 240Hz, so it suits dark rooms and long-term owners who never want to change a lamp. The TK700ST is brighter at 3000 ANSI lumens, uses a lamp, and hits 16.7 ms at 4K/60Hz, so it holds up better with some ambient light and costs less to step into. Reviewers praise both for sharp 4K and low lag; owners of lamp units accept bulb swaps, while LED owners pay more upfront for the lifespan.

• Choose the BenQ X500i if you have a dark or dim room, want the wider DCI-P3 color and 240Hz low-lag gaming, and prefer a light source you will not replace.
• Choose the BenQ TK700ST if you need more brightness for a room with some ambient light and want solid 4K/60Hz gaming without paying for an LED light engine.
