A short-throw 4K UHD gaming projector with an LED light source and 2 x 6 W Harman Kardon speakers. It is rated at 2,000 ANSI lumens (ProjectorCentral measured 1,657 in its brightest mode), and ProjectorCentral measured 18 ms input lag at 4K/60. It has no smart TV system and no lens shift.
Is the ViewSonic X2-4K right for you?
Good for
- Console gaming at 4K/60: 18 ms measured by ProjectorCentral
- High-refresh gaming at 1080p/240 (5 ms measured) or 1440p/120 (9 ms measured)
- Small rooms: a 0.69–0.83:1 short-throw lens
- Built-in sound: 2 x 6 W Harman Kardon speakers, plus Wi-Fi, Bluetooth and screen mirroring
What to plan for
- Rated at 2,000 ANSI lumens (1,657 measured): plan on a dim or dark room
- No full smart TV system: streaming relies on screen mirroring or a streaming stick
- HDMI 2.0 only: 4K is limited to 60 Hz, and 240 Hz works at 1080p only
- No lens shift and a fixed offset, so the mount or table height has to be right
- Audio out is 3.5 mm or Bluetooth; no ARC or eARC
