The BenQ TK705i is a 4K HDR DLP home projector with a native resolution of 3840 x 2160, a quoted 3000 ANSI lumens, Google TV built in and a listed input lag of 5 ms at 4K/60Hz over HDMI 2.1. It sits eighth in this guide, at £1,198.98.

Its listing is the one that leaves the contrast figure out altogether: the spec table says "High" where a number should be, so there is nothing here to set beside the contrast claims quoted elsewhere in this guide. The same table gives a maximum throw distance of 13.33 Feet and a minimum of "1.0" with no unit at all, lists 127.22 Volts, and pairs a 300-inch maximum image size with a first bullet that headlines a 150-inch screen. The star breakdown printed alongside the 4.4 rating totals 100 entries, while the advert states 32 ratings. Everything on this page is taken from the Amazon advert for this model — we have not measured the projector ourselves.
