The amount of quality and features this Hisense Roku TV (or R50B7120 to give it its more boring name) gives you for under £400 beggars belief. For starters, its 4K pictures are remarkably good for its price. Surprisingly, it uses a direct LED lighting system, rather than an edge-lit one, helping it deliver an unusually respectable contrast performance. It also provides a handy selection of HDR picture modes that let you choose your preferred balance between peak and ‘average’ brightness. Such HDR flexibility is essential, really, on budget TVs – but precious few rival models offer it. Similarly, while the Hisense Roku TV can’t deliver a wide range of colours, those it can look consistently natural by budget TV standards. What really seals the deal, though, is the R50B7120’s Roku smart system. This offers a mountain of apps, all accessible within a no-nonsense, easy to use and impressively slick operating system.
