Two of the Duo’s Asus stablemates are worth a look, too, both built around Intel’s new Alder Lake Core i7 processor.

The Blade 17 range starts at £2,899 but the top end 4K model is the same price as the 4K Duo 16 £4,499. The Blade 17 is also beautifully made, very powerful and its sound system is excellent. It may have only one screen but it’s large at 17.3in and sharp, too, at 3,840 x 2,160. One obvious choice is the latest Razer Blade 17.

All this trickery doesn’t come cheap but then Duo laptops were never intended to be affordable.

Internally, the new Duo 16 also gets the latest Nvidia mobile graphics – up to a GeForce RTX 3080Ti GPU – and the latest 6000-series AMD CPUs, including the eight-core AMD Ryzen 9 6900HX, which is unlocked if you fancy a bit of cheeky overclocking. The mechanism behind the innovative second-screen has also been modified in a significant way. Despite the larger screen the Duo 16 is actually fractionally smaller than the Duo 15 and only 100g heavier. Out goes the 15’s 15.6in 16:9 panel to be replaced by a 16in 16:10 affair. The main difference between the Zephyrus Duo 15 and 16 is, surprise surprise, the size of the main screen. Asus ROG Zephyrus Duo 16 review: What you need to know
