Description

Full specifications Compare alternatives

Dedicated RPG, FPS and Sports game picture modes are tuned for different genres without sacrificing true 4K UHD detail, and input lag is rated at 16.7ms at both 1080p and 4K, dropping to 4.2ms at 1080p/240Hz for fast competitive play. HDR10 and HLG support add extra contrast and colour range for supported content.

Dual HDMI 2.0b inputs with eARC, a 5W speaker chamber and auto 2D keystone correction make the TK700ST simple to set up for console gaming and movie nights alike, in rooms too small for a standard-throw projector.

Planning from a real wall? Use the projector screen size calculator to upload a photo, preview the image to scale and find projectors that fit within your maximum available space. Replacing an existing projector? The projector replacement calculator checks whether this lens covers the ratio your current mount needs.

Distances are lens-to-screen, calculated from the manufacturer's stated throw ratio; allow for lens shift and mounting hardware. Always confirm against the manufacturer's installation guide before fixing mounts.
