Its pictures really do jump off the screen with an intensity far beyond anything else we have seen at anything like the same price. In fact, they leave the vast majority of much more expensive mid-range and even a few really premium TVs looking dull by comparison. Including, as TCL would want it to, OLED models, with even the latestMLAandQD-OLEDsets falling some way short of the sort of brightness the C845K can achieve.

Testing a TV is a long and complex process because a modern TV simply does so much. Not only does it need to handle a variety of content resolutions – standard-definition, 1080p, 4K and sometimes 8K – and both standard dynamic range and high dynamic range (the latter in a number of formats), all of which need to be specifically tested, is also has a sound system with various advanced settings and a full smart platform. A TV is an all-in-one device in the best sense, but that also makes it a challenging review proposition. The 65-inch take on LG's C3 earned just the four stars, but that was for a very good reason: it wasn't a big improvement on the C2. This allowed rivals such as the Sony A80L to gain ground. But if it's gaming we're talking about, LG's effort is the better bet. The most widely used panels are those with 6, 8, and 10 bits for each of the RGB components of the pixel. They provide 18-, 24-, and 30-bit color, respectively.We have state-of-the-art testing facilities in London and Reading, where our team of expert reviewers do all of our testing. This gives us complete control over the testing process, ensuring consistency.What's more, all review verdicts are agreed upon by the team as a whole rather than an individual reviewer, again helping to ensure consistency and avoid any personal preference.

The percentage of the approximate area, taken by the active part of the screen, to the total front area. If you're a gamer, it's also worth considering the next-gen gaming features of your prospective new TV. Xbox Series X and PS5 gamers can gain a competitive advantage on certain games if their TV supports 4K 120Hz, while VRR support can result in a smoother gameplay experience. ALLM, meanwhile, simply ensures that you automatically get the best visual experience from both games and movies / TV shows. If you are a more casual gamer or not a gamer at all, you can pretty much disregard these features, and doing so will likely save you a lot of cash. How we test How we test TVs The Sony A80L is the TV surprise of the year. It's based on 'traditional' OLED technology (i.e. it's not a QD-OLED or MLA model) so we broadly thought we knew what to expect, but it stunned us during our extensive test by offering a picture performance with a near-perfect balance of the spectacular and the subtle. It sounds good by TV standards, too, and the feature set will be strong enough for all but the most hardcore of gamers. The What Hi-Fi? team has more than 100 years of experience reviewing, testing, and writing about consumer electronics. The C845K delivers outstanding sharpness and clarity with native 4K sources, and while its motion handling with 24p sources isn’t quite as refined and natural with or without processing active as the best rivals, it is fairly free from unwanted side effects and still looks natural enough to leave you immersed in what you are watching.The ratio between the horizontal and the vertical side of the display. Some of the standard and widely used aspect ratios are 4:3, 5:4, 16:9 and 16:10.
