BenQ's sharp-looking new 4K projectors promise HDMI 2.1 with ultra-low lag for gaming, plus great streaming and connectivity options

• BenQ launches two new projectors with 4K and HDR
• 3,000 ANSI lumens, up to 150-inch image sizes
• 5ms latency promised for gaming

BenQ have announced two new smart 4K home projectors, the TK705i and TK705Sti. With 3,000 ANSI lumens of brightness they're bright enough for use in everyday lighting, so you won't need to draw the blinds for your Netflix binge or gaming marathon – and they're set up for both of these things.

As with previous TK series projectors, the STi label identifies the shorter throw model. They're otherwise pretty much identical with Ultra HD resolution, screen sizes of up to 150 inches, the same brightness, and the same color accuracy.

The only other significant difference is that the TK705i has motorized optical zoom and the STi model doesn't.

BenQ TK705 Series: key features

Both projectors feature BenQ's Cinematic Color and HDR-PRO tech to deliver a claimed 98% Rec.709 color accuracy. They have low-lag HDMI 2.1 connections with ALLM for gaming (5ms latency at 4K 60Hz) and feature Bluetooth 5.2 as well as USB-C with 30W power delivery.

The projectors are designed for plug and play setup, with an 8-way Smart Image Adaptation system that BenQ says aligns big screens in seconds by adjusting the zoom, 2K keystone, focus and other key settings automatically.

Google TV provides built-in streaming support, with the usual high-profile streaming apps including Netflix, Prime Video and YouTube.

The one thing we don't know yet is how much these will cost: until we do, we won't know how competitive these projectors will be with the best 4K projectors. We'll keep you posted.
