Spec, translated

The '240Hz and 4.2ms' spec means that at 1080p resolution, the projector has monitor-grade responsiveness, making it ideal for competitive gaming. This performance is not available when running at 4K.

Lab notes

The observations that actually change the buying decision.

The 4.2ms input lag is its primary selling point, but this is only achievable at 1080p resolution with a 240Hz signal. Expect higher lag at 4K.

The light source is laser phosphor, rated for 20,000+ hours. This eliminates the cost and maintenance of traditional lamp replacements, a significant long-term value.

4K resolution is produced by a DLP chip using XPR pixel-shifting. It's a convincing facsimile for gaming and movies, but it is not native 4K.

The projector lacks optical lens shift. Setup flexibility depends on digital keystone and corner correction, which sacrifice image resolution and can introduce artifacts.

Why you should buy

Gamers who prioritize input lag and refresh rate above all else will find this a compelling option. The bright laser source also makes it suitable for mixed-use entertainment in rooms with some ambient light.

Why you should skip

Home cinema purists seeking perfect black levels, wide color gamut, and true native 4K resolution should invest in a dedicated theater projector. Anyone with an awkward room layout will miss the flexibility of optical lens shift.
