Each model features dual HDMI inputs for cabling up to a games console, set-top box, laptop, Blu-ray player and so on. And there’s an enhanced gaming mode that’s said to get input lag down to just 4.2 milliseconds for 1080p gaming, while boasting a maximum refresh rate of 240 Hz. Thrown image size can get up to 300 diagonal inches.

The projectors can also be used to watch movies and shows at up to 4K UHD (3,840 x 2,160), and are capable of receiving and displaying HDR10 and Hybrid Log Gamma high definition content for a more lifelike viewing experience. There’s support for the Rec.709 color gamut too, and for movie content shot at 24 frames per second for cinema-like viewing “exactly as the director intended.” Deep blacks shouldn’t be a problem either thanks to the 1,000,000:1 contrast ratio.

There’s no need to redecorate in projector-friendly white when you buy either of these new models, as the Wall Color setting adjusts the thrown image based on the color of the wall – which can compensate for six different background colors, including yellow, pink and light green.

Elsewhere, the units feature manual zoom and keystone correction, each rocks a 10-W integrated speaker – but there are also analog and digital audio outputs for connecting to bigger and better audio systems – and there’s a USB Type A port for plugging in a Chromecast, Roku or other smart entertainment dongles. The lamp light source is good for between 4,000 hours in full brightness and 10,000 hours in eco mode.

The UHD38 gaming projector is available in the UK now for £1,099, while the UHD35 comes in at £999 (that’s about US$1,500 and $1,360 respectively, though there’s no word at the moment on a US release). Each unit comes with a backlit remote.
