It’s important to preface this by saying that we’ve not reviewed many Sharp TVs at What Hi-Fi? over recent years and all the advice we have to offer is based purely on specs, design, on-paper features and our vast experience in the TV sector. These terms refer to the number of pixels that make up the image on the screen. So, 4K screens offer four times more pixels than HD screens, with 8.3 million pixels working across the screen. This makes for more detailed and accurate images. Here's a list of the most common ones when looking for the best 50-inch smart TVs.

Many smart TVs come with a feature called something similar to ‘Screen Mirror’ or ‘Wireless Display’. This pairs with a smartphone via an installed app. This then shows your phone screen on the TV, which is great for viewing photos, videos or video chats. This is an important app for anyone who loves any one of the plethoras of YouTube personalities, gamers or influencers. Much like the smartphone app, this smart TV app will allow unlimited and free access to countless hours of independent entertainment. YouTube does offer a subscription service, known as YouTube Premium, but this doesn’t restrict free access to a vast selection of content. Spotify The most obvious feature that sets the former What Hi-Fi? Awards-winning Philips 48OLED807 apart from the other sets in this list is the inclusion of Philips’ Ambilight technology.Of these two 'dynamic' HDR formats, Dolby Vision is by far the most prevalent, both in terms of TVs and content, and if you have to choose between one and the other, that's the one we'd recommend. That said, you can now buy TVs from the likes of Philips and Panasonic that support both Dolby Vision and HDR10+.

The latest model is no different. To put it plainly, there’s no better-specified TV available at this size. While neither MLAnor QD-OLEDtechnology has made it below 55 inches yet, the C3 uses the best 48-inch OLED panel currently available from sister company LG Display, and it's crisp and well-defined, producing an image that’s really solid and has a three-dimensional feel. In fact, the increased pixel density of having a 4K resolution squeezed into a 48-inch space means this smaller C3 looks significantly sharper than its 65-inch C3 sibling.The key TV battleground right now is gaming specs, and the 48-inch C3 very much has the high ground here too.Unlike the TV from Asda, the Sharp set is powered by Android TV, which is developed by Google and is compatible with a huge number of streaming apps and games. Featuring Dolby Vision HDR for cinematic detail and Smart TV by Roku, the Sharp 50FJ2K has a top spec at a bargain price. Dolby Vision HDR performance was also dazzling when we played Thor: Love and Thunder, with the set retaining detail in the brightest parts of the picture. No Time to Die delivered equally great results in HDR10, with the picture remaining crisp and bright throughout the movie.

HDR10+ is a rival format to Dolby Vision. Created by Samsung, it also uses dynamic metadata but, whereas Dolby Vision is licensed, HDR10+ is a free, open format that any company can deploy as it sees fit. They're currently only available as open-box models but that brings some possibilities of real bargains. That said, it’s worth bearing in mind that to upgrade to the 4K models is only a matter of a few dollars at the 50in size and - a relatively small price to pay for four times the pixels and HDR support. Costco UK's other Sharp TV looks a little more promising. At the other end of the size scale, the Sharp LC-24DHG6131 TV/DVD player combo appears a good match for the set above at Currys but at a more favourable price. VerdictIf you are 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 it's likely that doing so will save you a lot of cash. Should you buy a 4K or Full HD TV? While a certain type of AV fan will always be drawn to the greater light stability and pixel-level light control you get with OLED TVs, the Samsung QE50QN90B’s combination of higher HDR-friendly brightness, peerless (by LCD standards) light controls and impressive image flexibility ensures it has more than enough charm of its own to make a convincing case for itself. Especially for people looking for a TV able to take on a bright room environment.
