Hard fact first: You won’t find any of the best 120Hz 4K TVs regularly inhabiting the bargain aisles - but if you’re into gaming, then investing in a 4K flatscreen that offers HDMI v2.1 connectivity makes a lot of sense right now. Only HDMI v2.1 ports have the bandwidth (40Gbps) to accommodate a 4K 120 frames per second video output, and while the numbers of titles available that actually take advantage of this are limited, we predict you’ll see an explosion in these as more and more studios explore the true potential of the PS5 and Xbox Series X.
120Hz HDMI ports can be found on both 4K UHD TVs and high-end 8K models, where they may be listed simply as an 8K input. Of course, there’s next to no 8K content to be viewed or played right now, but ensuring you have that valuable port is what you need for high frame rate gameplay, so always make sure you see the term 'HDMI 2.1' in the specs list.
Helpfully, all of the best 120Hz 4K TVs also come with other game-facing tech, like VRR (Variable Refresh Rate) and ALLM (Auto Low Latency). The latter automatically puts a TV in Game Mode, for the lowest possible input lag, while the former eliminates judder and tearing artefacts. In short, both are very nice things to have.
As a last point on value, now that even the latest models of 120Hz 4K TVs have been available for a few months, and we head toward the chaos of the end-of-year sales, it'll pay to do some research around the upcoming Black Friday PS5 TV deals to know what to expect as 120Hz TVs will undoubtedly be on sale, and also be some of the picks of the whole period.
So which is the best 120Hz 4K TV to partner with your next-gen games console or gaming PC? Read on for our top buys...
The best 120Hz 4K TVs
The Q80T is a formidable frag-friendly flatscreen that’s fantastic value (even though it's now superseded by 2021's NeoQLED panels, this has aided its value offering!). Its image quality is excellent, with dynamic HDR, superb colour fidelity, and razor-sharp detail. This is actually the cheapest Samsung QLED TV to offer a full array backlight, which means this 120Hz 4K TV will give you better HDR and contrast, too.
Feature attractions are many and various. In addition to 4K 120fps support, there’s VRR and ALLM, plus FreeSync support for PC gamers. We also love its OST (Object Sound TrackIng) audio system, which positions speakers both top and bottom of the set, offering a different edge to the best 120Hz 4K TV.
Samsung’s Tizen-connected smart TV platform is one of the best out there, too. It doesn’t just offer copious streaming apps and catch-up TV players, but there are various smart functions to enjoy, too, like Ambient Mode and Mobile Multi-View twin-screen mode, which is handy for gamers who want to sync their play with someone streaming on Twitch.
The icing on the cake is a two-speed Game Mode. Game Motion Plus keeps some picture processing turned on, for maximum eye candy, while hardcore Game mode just improves input lag, to an astonishing 8.7ms (1080/60). All things considered, this really is the best 120Hz 4K TV, pound for pound, that you can buy.
Positioned just above LG’s cheaper BX range (see more on that below), the CX pulls rank through its use of the brand’s premium Alpha 9 processor, which powers a whole bunch of AI-enhanced sound and vision enhancements. And what enhancements, they are: picture quality is as good as it currently gets with this LG OLED. There's an excellent level of detail, with effective HDR dynamics and brilliant colour fidelity, which make the CX a treat to stare at. And it comes with a full quartet of HDMI 2.1 inputs making it perfect for multi-device setups and making it supremely well-equipped for the next generation of gaming. That’s more 120Hz 4K support than any of us will probably need for quite some time.
Other niceties include VRR and ALLM modes, plus G-Sync and AMD FreeSync compatibility for PC gamers. LG’s webOS smart platform, navigated with the brand’s Magic remote control, offers plenty of streaming entertainment too, including Amazon Prime Video, Netflix, Apple TV+ and Disney TV+.
Taking its already-brilliant QLED panel tech and going even further with it, Samsung's 2021 range of TVs come in no better form than the QN90A/QN95A. This has Mini-LED-powered 4K flagship has deep blacks, terrific quality, vibrant colours and contrasts, and exquisite HDR management.
Image quality is superb, thanks to an advanced AI-powered Neo Quantum 4K processor, while an Intelligent Mode optimises all sources, making it an easy screen to live with, whatever you watch, and whatever you prefer.
The television comes with one of Samsung's One Connect Boxes which connects to the set via a fibre optic cable, while an extra unit to factor into the setup, this does allow for four HDMI 2.1 connections meaning anyone with a multi-gaming-device setup is surely catered for well. Smart connectivity is provided by Tizen, Samsung’s smart TV platform and there’s a wide range of apps available, including Netflix, Prime Video, Apple TV+, Disney+, and Now, plus all the usual catch-up TV services.
New on the QN95A is the Game Bar, a dedicated interface for tweaks and adjustments. Latency is very good: we measured input lag at 10.1ms (1080/60), in standard Game mode. When it comes to HDR, HDR10, HLG, and HDR10+ Adaptive are all supported, but there’s no Dolby Vision compatibility, which is a shame - but still doesn't impact the overall performance of the TV.
Even the TV sound system is nicely improved and very good, thanks to Samsung’s OTS+ sound system. Overall, a stunning high-end TV option, and if you want the absolute best 4K QLED screen Samsung makes, then the Neo QLED QN95A is it. File under expensive, but ridiculously good.
For information, this television is referred to as the QN90A in the US, while in the UK and Europe is called the QN95A. There are only the mildest of actual differences between the two and they are, in essence, the same panel.

The brand-new model in LG's premium OLED range, the G1 is already one of the best 120Hz 4K TVs going in 2021. It offers the latest in excellent TV-bound gaming features, with beautiful design, and leads LG's charge on the gaming front this year. If you're after the very latest LG OLED TV then this is the one to go for with gaming in mind.
However, the big caveat to get out of the way is that the G1 is specifically designed to be a wall-mounted screen - it doesn't even come with a stand or feet (even in the year 2021). You'll have to pay more for these, but if you're going for one of the best, you're likely to be OK with that to get the perfect setup for you.
Cutting right to it, the big news is that the G1 uses LG's brand new Evo panel and it provides the best HDR performance yet from LG. Teamed with the brand’s latest 4th Gen Alpha 9 image processor, and throw in some AI picture enhancement technologies, and the results are stupendous: incredible pictures, wonderful detail, and top-notch motion handling. The G1 supports ALLM (Auto Low Latency Mode), VRR (Variable Refresh Rate), VRR G-Sync, and VRR AMD Freesync, so it has proper gaming credentials, including, of course, HDMI 2.1 - of which all four ports are of the latest high-speed version.
The icing on the cake, gaming-wise, is the new Game Optimizer interface that allows in-depth tuning, including game genre selection, based on game style. An absolute banger of a 120Hz 4K TV.

The C1 is the 120Hz 4K TV every new-gen gamer is going to want this year. Cutting to the chase, the TV's four 4K 120Hz-capable HDMI inputs, plus a dedicated Game Optimizer control panel, means it's as ready for gaming as a TV can be, and it'll be great for those who'll have multi-new-gen devices to plug in.
The premium image quality on offer, which leans more heavily on AI smarts than we’ve seen to date, is spectacular, both with native 4K and up-scaled HD; offering deep blacks, vibrant hues, and almost three-dimensional levels of details, this is an OLED 4K 120Hz TV to be ogled.
Motion handling has also had a tweak from earlier series: TruMotion Smooth is still around if you like a slick interpolated look, but there’s also a Cinematic Movement option that does something clever with frame merging, so movies always look filmic - and it works well. HDR performance is also extremely good. The C1 supports Dolby Vision, HDR10, HGiG, and HLG. There’s no support for HDR10+ though.
The set is available in a wide range of screen sizes, beginning at 48-inches (although this offers no appreciable cost saving over the step-up 55-incher), and boasts a powerful new processor, in the shape of LG’s 4th Gen Alpha 9 chipset. AI plays a role on the audio front too. AI Sound Pro upscales stereo and 5.1, and there’s a Dolby Atmos decoder on-board. Streaming services and catch-up support are extensive.
If you’re looking to take home a top 120Hz 4K TV from this year already, the LG C1 is the obvious front runner.

The X90J represents the biggest update to Sony’s mid-range 4K HDR range in years. The brand has been treading water somewhat and has been particularly slow to roll out the kind of High Frame Rate HDMI functionality next-gen gamers have been demanding. The X90J sets out to fix that.
Two of its four HDMI inputs support 4K 120fps so that'll have you covered with any of the new-gen consoles, but, rather cutely, the TV will optimise picture parameters automatically for PlayStation 5 HDR, and automatically register whether the PS5 is playing video content or a game. Neat.
Picture clarity is outstanding, thanks largely to Sony’s new Cognitive XR Processor. This takes a rather different approach to picture processing than rivals and aims to replicate how people see objects in real life, by concentrating on natural focal points in the image. The screen is divided into zones and employs AI to determine where the ‘focal point’ is in the picture. It then concentrates its image processing on those parts of the picture. The only feature-based caveat is that we’re still waiting for a promised firmware update that will enable VRR (Variable Refresh Rate).
The X90J uses a Full-Array local dimming backlight system, which is precise enough to deliver deep blacks and plenty of dimensional shadow detail. There’s support for Dolby Vision too, but not HDR10+. Still, it does warrant IMAX Enhanced certification, which can’t be bad. The Cognitive Processor XR also handles audio, analysing the sound position within a signal to match what’s on the screen, and upconverting where necessary. This works well with Sony’s Acoustic Multi Audio System. Speaker drivers have been placed around the minimal frame, resulting in a larger, more involving soundstage.
Overall, we rate the X90J a winner and a great choice for a top 120Hz 4K TV - particularly if you have a PS5.
Undercutting its CX stablemate, the LG BX warrants serious attention if you don’t want to totally bust your display budget. Behind the glass is a third-generation Alpha 7 image processor, while the rest of the LG OLED range use the more advanced Alpha 9 chip, but we doubt you’ll feel short-changed. Pictures are crisp, colour rich, and dynamic., and combined with its price point, the BX is easily one of the best 120Hz 4K TVs going.
It’s well equipped on the smarts side, thanks to ThinQ AI and webOS, but there’s some cost-cutting on HDMI inputs. Only two of the four provided support 4K@120Hz; the remaining two are regular 8-bit 4K/60Hz inputs. This shouldn’t be a problem for most, as you’ll be still able to connect both a PS5 and Xbox Series X for high frame rate gaming. For PC gamers there’s NVIDIA G-SYNC compatibility, plus VRR (Variable Refresh rate) and ALLM (Auto Low Latency Mode) compliance which is a good bonus
On the debit side, there’s no Freeview HD which means catch-up TV players are AWOL - but who has time for regular telly these days anyway? Netflix, Twitch, Prime Video, and Disney+ are just a few of the heavy-hitting streaming apps on-board.
This is the best Sony LED LCD TV you can buy today if you're looking for one of the best 120Hz 4K TVs from the very makers of the PS5.
The XH90 is the only TV in Sony’s current line-up that currently supports 4K @ 120Hz, making it uniquely appealing to PS5 and Xbox Series X owners. There’s support for ALLM and VRR (promised via a firmware update) too. And the best news is that it’s available in a huge range of screen sizes, specifically 55-, 65-, 75- and 85-inches (KD-55XH9005, KD-65XH9005, KD-75XH9005, KD-85XH9005). In the US, the set is known as the XBR-55X900H, XBR-65X900H, XBR-75X900H, XBR-85X900H.
The TV runs Sony’s tried and tested X1 processor, with 4K X-Reality PRO enhancement and Object-based HDR remastering, making it particularly great at upscaling.
A full array backlight also helps maximise its HDR performance. There’s support for Dolby Vision, as well as regular HDR10 and HLG. The Game mode is also pretty sprightly, enabling just 17ms input lag.
Editors note: When one of the GR+ hardware team was testing this TV for review, they found it was great for gaming but was a bit disappointing with the native Netflix app. It struggled with dark scenes with lots of blocky image artifacting (this never happens when gaming). Pop a Fire TV stick in though and problem solved.
More likely than LG’s OLEDs to benefit from serious price-cutting, this 9-series Nanocell set is well worth keeping on your watch list if you're ever on the hunt for a bargain when scouting the best 120Hz TVs. Like other LED LCD TVs, it’s immune to image burn, and full array dimming makes the most of its HDR talents, which include Dolby Vision and HLG.
The set has two high-bandwidth 120Hz HDMI inputs, for 4K 120 frames per second gaming, as well as VRR and ALLM.
The set’s smart game is strong too, thanks to LG’s versatile webOS platform, with key streaming apps (Netflix, Prime Video, Disney+) on-board. This is one to watch (in every sense) and would make a prime candidate for those who can't quite stretch the budget to an OLED or Samsung QLed television.
Looking for a 4K QLED bargain? The Q70T is the cheapest Samsung QLED to contend for best 120Hz 4K TV in 2021, and it’s a bit of a steal. There’s a catch though: just one of its four HDMI inputs (numero 4) is an HDMI 2.1 port - the rest max out at 4K 60Hz. This shouldn’t be a problem if you’re loyal to a single next-gen games console, of course. The set also lacks local dimming, which limits HDR precision and contrast. The good news is, during real-world watching, and certainly during fast-paced gameplay, this isn’t likely to be that noticeable (although you might spot some blooming when dungeon crawling). In other respects, the Q70T offers excellent colour vibrancy and fine detail.
As with other Samsung’s QLEDs, you get two Game Modes - Game Motion Plus and regular Game. Input lag is 20ms and 9ms (1080p/60) respectively, which is good going, too, which rounds of a great package when looking to get a proper QLED 120Hz 4K TV.
Do most 4K TVs support 120Hz?
Because the two terms and specs ('4K' and '120Hz', respectively) are becoming more and more intertwined, this is an increasingly common question. But the answer is a clear 'no' - for now. As it stands, it's still the minority of 4K TVs that genuinely offer 120Hz capability, but much like all TV panel tech, it is beginning to become more prevalent and 'trickle down' through the tiers of televisions.
Thus, by default, not all 4K TVs have the refresh rate of 120Hz offered by HDMI 2.1 ports - you'll have to look out for these features specifically when you're browsing for TVs.
