The Sony X90J fixes that, with some game-focused spec that even outstrips its pricier Sony sets. Powered by the Google TV operating system, the Sony X90J comes complete with two HDMI 2.1 ports, VRR, and ALLM — a sure-fire combo for a fluid, reactive, lag-free gaming experience. The TV would overheat with HDR content, too. There was a period of time where the LED light would flash red, and a notification pop up signalling the TV was overheating. It happened across a range of apps, and while it did occur during the year’s hottest days, the window was open and the area well ventilated. I’m not sure heat is a great excuse considering nothing else was affected. is a fancy way of saying ultra-high definition. A 4K TV display has at least 8 million active pixels. With a standardised resolution of 3,840 x 2,160, it has four times the resolution of the HD standard of 1080p. Top branded TVs also upscale regular HD and SD content so it looks as polished as possible. Do you need a 4K TV for gaming?

The TCL weighs less and looks a little less bulky from behind. The IR receiver/LED indicator below the TV logo blinks to confirm remote control presses or flashes red when the TV encounters an issue, to name but two potential occurrences. When it comes to 4K, bigger is indeed better. And why not? A bigger screen makes sense when you're looking to get the most out of the 4K quality — and to set these TVs apart from smartphones and small devices, which we increasingly use to watch HD content. The smallest size in 4K is usually 48 inches, going up to 55, 65, 75, and even 80+ inch screens. Screen size is measured diagonally, from corner to corner. What is low input lag?While TVs come with multiple HDMI ports, not all ports will be HDMI 2.1 (2.0 is often included as standard — anything under 2.0 won’t be able to handle 4K resolution at anything higher than 30 frames a second). Fortunately, most of the latest crop of 4K TVs will include at least one HDMI 2.1, which is all you need. This is unless you want to have both a PS5 and Xbox Series X plugged in at once. The PS4 and the last Xbox will happily make do with HDMI 2.0 — as will the Nintendo Switch. What does 120Hz mean?

There’s support for AirPlay 2 and HomeKit, if you’re in the iOS ecosystem and want to either share video/audio content or add the TV to your list of smart devices. Alexa and Google digital assistants are covered but support isn’t native – you’ll need an external device to get either of them going.If there’s a silver lining to the 5-Series’ performance, it’s that it only has 11ms of lag and has a game mode that will turn on automatically when you turn on a video game. Combined, these two features certainly help games feel more responsive – something we can attest to after playing several hours of intense UFC 3 matches on the 5-Series – but without HDMI 2.1 and/or 120Hz support, it’s really not a great fit for the Xbox Series X or PS5. Whites are crisply and purely defined, and with 4K SDR content – such as Netflix’s Sense8 – concerns about how punchy and vibrant the TV can be dissipate. Turn to a stream of The Crown on Netflix in Dolby Vision HDR, though, and those issues rear their head again. Complexions of the royal family take on a pallid tone, with the image less expressive.

Panasonic’s mid-range TVs have always rated very highly among the experts, though as recently as last year they were missing key tech for up-to-the-minute gaming. The Panasonic JX940 is a literal game-changer though, thanks to what it calls “Game Mode Extreme”. This adds 4K at 120Hz, VRR, and two HDMI 2.1 ports. That all combines with ALLM and AMD FreeSync Premium for an all-round smooth, lifelike gaming experience.
