Wall things bright and beautiful

If you want a really big telly, you don't want a telly at all - just a large blank surface to point one of these fine projectors at

BenQ GP520

What's the story? Relax: 'GP520' might sound like the name of a scary AI doctor, but this is another model in BenQ's wide range of wall-beamers.

On paper it's a fantastic all-rounder. With 2600 lumens of brightness in a native 4K projector, the picture should hold up in any conditions. Three integrated sensors can read the environment based on ambient light, screen distance and even wall colour, optimising the image accordingly.

The GP520 also throws in autofocus, keystone correction, screen fit and obstacle avoidance, so moving and setting up between rooms is no faff. And for user-friendliness, there's Google TV and its streaming apps.

Its audio specs aren't too shoddy either, with twin 12W speakers powered by Dolby Atmos-plus a Bluetooth button for hooking up to a speaker or headphones.

Gamers are covered thanks to HDMI 2.1 ports and ALLM, which minimises lag for smoother gameplay, and there's passthrough power for charging other devices via USB-C.

Is it any good?

The GP520 impresses right out of the gate. Whether dealing with 4K or Full HD video, it makes colours pop with vibrancy, and images have crystal clarity.

Colour accuracy is on the money, movement is handled well, and contrast is decent, though not quite class-leading.

There are a few minor niggles: the remote feels light and flimsy, while the projector itself is mostly scratchy plastic. Plus, unsurprisingly given its compact dimensions, the audio output lacks the thumping bass response of a bigger projector.
