We test all-in-one PCs more thoroughly than any other organisation

We've put hundreds of PCs through our independent lab test. We check the screen and sound quality to make sure you’ll get the most from films and TV; we measure colour accuracy and brightness for the screen, plus frequency response from the built-in speakers. 

We also test the bundled keyboard and mouse that come with the PC - are they wired or wireless models? Does the keyboard feature an irregular key layout or size, plus is the mouse comfortable to use for long periods of time? We're sure to leave no stone unturned.
