Best TVs 2026: Which 4K Smart TV Should You Buy?

Television has quietly become the best-value technology you can buy. A £279 set today looks better than a £1,500 one from a decade ago, and the gap between mid-range and flagship is now visible mainly in a darkened room. That reframes the question: not "which is the best TV?" but "how little do I need to spend before the difference stops mattering?" These are the best TVs to buy in 2026, with UK prices checked on Amazon UK on 15 July 2026 — confirm the current figure before buying.

The Short Version

  • Best overall — LG OLED C5 (55-inch). The picture to beat, with perfect blacks, at £998.97.
  • Best value OLED — LG OLED B6 (55-inch). Most of the OLED magic for £250 less, at £749.00.
  • Best value overall — TCL 55C6K QD-Mini LED. 1,000 nits of brightness for half the OLED money, at £499.00.
  • Best for gaming — Hisense 55U7QTUK Mini LED. A 144Hz panel built for consoles and PCs, at £506.00.
  • Best budget — Hisense 55E6QTUK. A genuinely good 4K set for £279.00.

Best Overall: LG OLED C5 (55-inch)

If you want the best picture, the LG OLED C5 at £998.97 is still the one. OLED switches off individual pixels, so blacks are absolute and contrast is something no backlit TV quite matches — watch a film in a dark room and the difference is obvious. LG's α9 processor handles upscaling well, and it is superb for gaming too, with 144Hz support and the full set of HDMI 2.1 features. It is a lot of money for a 55-inch screen, and it earns it — but read the buyer section before you assume you need one. Check the price on Amazon

Best Value OLED: LG OLED B6 (55-inch)

The LG OLED B6 at £749.00 is the sensible way into OLED. It uses the same self-lighting panel technology as the C-series — so the same perfect blacks and superb contrast — with a slightly less powerful processor and marginally lower peak brightness. In a normal living room, watching normal content, most people would struggle to tell the two apart. Saving £250 for differences you will notice only in a side-by-side comparison is an easy call.

Best Value Overall: TCL 55C6K QD-Mini LED

Here is the pick most people should actually buy: the TCL 55C6K at £499.00. Mini LED backlighting with quantum dots gets you around 1,000 nits of peak brightness — considerably brighter than an OLED, which matters far more in a sunny living room than perfect blacks do. Contrast is not OLED-level, and you may spot some blooming around bright objects on dark scenes, but for daytime telly, sport and streaming it delivers perhaps 85% of the flagship experience for half the price.

Best for Gaming: Hisense 55U7QTUK Mini LED

Console and PC gamers should look at the Hisense 55U7QTUK at £506.00. Its Mini LED panel runs at 144Hz, so it handles a PS5 or Xbox at 120Hz with room to spare and suits a gaming PC pushing higher frame rates, with low input lag and variable refresh rate to keep motion clean. Brightness is strong for HDR games, and picture quality holds up for films too. For the money, it is the most complete gaming television here. Check the price on Amazon

Best Budget: Hisense 55E6QTUK

At £279.00, the Hisense 55E6QTUK is remarkable. It is a 55-inch 4K set with decent HDR handling, a full smart platform and picture quality that would have cost four figures a few years ago. It is dimmer than the pricier sets, motion is less assured and it will not thrill you in a dark room with a film — but for a bedroom, a spare room, a first flat or anyone who mainly watches daytime TV and streaming, it is all the television most people need.

Who Should Buy Which?

Be honest about your room and your habits. If you watch films in a darkened room and care about picture quality, an OLED is genuinely worth it — the C5 if budget allows, the B6 if you would rather keep £250. But for most households, the TCL Mini LED at £499.00 is the smarter buy: in a bright living room its extra brightness beats OLED's perfect blacks, and nobody has ever regretted spending less on a telly. Gamers should take the 144Hz Hisense, and on a budget the £279 Hisense is honestly fine. Two more things: ignore 8K entirely, as there is essentially nothing to watch on it, and remember every flat TV has weak speakers — a soundbar from our best soundbars guide improves your viewing more than doubling your TV budget will.

How to Choose a TV

A few things decide the right TV. Panel type is the big one: OLED lights each pixel individually for perfect blacks and the best contrast, while Mini LED and QLED use a backlight and win on sheer brightness — OLED for dark rooms and film nights, Mini LED for bright living rooms. Brightness is measured in nits, and around 1,000 nits is where HDR starts to look genuinely punchy in daylight. Size matters more than specs: 55 inches suits most living rooms, 65 inches is better if you sit further back, and 83-inch sets exist if the room is huge. Stick to 4K and ignore 8K — there is no content, and it will not look better. For gaming, look for 120Hz or 144Hz, HDMI 2.1 and variable refresh rate. Finally, do not trust the audio: built-in speakers run from about 20W to 60W and all sound thin, so budget for a soundbar — our best soundbars under £200 guide covers the affordable end.
