The TCL QM6K Sequence is our favourite finances 4K TV as it combines the core LCD applied sciences we search for in any nice LCD TV (reminiscent of mini-LED backlighting, native dimming, and quantum-dot shade) with our favourite good platform (Google TV), whilst additionally including some surprising enhancements (the next refresh charge and higher audio efficiency) that distinguish it from different in a similar fashion priced TVs.
It has what each LCD TV value purchasing wishes: an ideal backlight. As videophiles and cinephiles know, OLED TVs glance so nice as a result of they don’t want backlights: Their pixels are self-emissive. Despite the fact that video processing and shade accuracy are vital, an LCD TV’s backlight is what makes or breaks it in any case, and the QM6K is provided with one of the vital easiest backlights amongst TVs in its worth vary.
What makes a nice backlight? A mix of energy and keep an eye on. The QM6K will get decently vivid with excessive dynamic vary video (600 nits or extra in its Dolby Imaginative and prescient IQ mode), and it pairs that brightness with deep black ranges (averaging round 0.002 nit, a virtually inconceivable point of shadow intensity for a budget-oriented LCD TV). This makes for fetching, high-contrast scenes. As an example, the flare scene in The Batman wishes realistically darkish shadows along ample brightness that it in reality looks as if a highway flare, and the QM6K pulls that off.
Attaining simultaneous excessive brightness and deep darkness is inconceivable in an LCD TV with no procedure referred to as native dimming, through which the backlight is divided into zones that may function independently of each other. In 2025 TCL has carried out two proprietary applied sciences for this procedure; I received’t pass into the corporate’s professional phrases right here, however the finish function is a finely tuned set of rules addressing each how intelligently the QM6K’s dimming zones turn on and the way briefly the ones zones function.
Each TV era makes trade-offs, and the issues with native dimming are associated with “bloom” (when a vivid object bleeds into the encompassing darkish spaces) and “trailing” (when backlight zones take too lengthy to dim as a vivid object strikes throughout them, so it sort of feels to go away a ghostly path of sunshine at the back of). The QM6K isn’t easiest in both regard, but it surely does a a lot better process than competition on this worth vary. Maximum finances LCD TVs don’t have native dimming in any respect.
This TV delivers shiny colours, particularly for the fee. Quantum dots are microscopic nanocrystals that react to blue mild, massively expanding the perceptible saturation of reds and vegetables in a TV. It’s a era that used to be prior to now reserved for higher-end TVs however now seems in more-affordable fashions. Alternatively, there’s been some hubbub in recent times about using quantum dots in finances TVs, with some corporations — together with TCL — being accused of saying “quantum shade” with out in reality enforcing the vital micro-crystals.
I confess that I haven’t cracked open the QM6K to test whether or not it in reality has a quantum-dot layer. However I will no less than ascertain that its shade presentation is nice ample for what you’re paying for it. My measurements confirmed that the TV can reproduce 98.5% of the Rec 709 shade house (for same old HD content material), round 83% of the DCI-P3 house (for present UltraHD content material), and a hair beneath 60% of the huge Rec 2020 shade house (the function for long term Extremely HD content material).
When put next with the colour features of top rate TVs, the ones effects are admittedly middling. Alternatively, you’re not going to understand the colours as middling until you’ve downgraded from a significantly dearer TV or are looking at this type in a reference viewing surroundings. I’ve observed the flare in The Batman glance extra red-orange and extra wholly saturated at the $4,000 TVs I on occasion have the excitement to check, however the QM6K’s rendition is lots shiny, particularly when that flare is nestled among a surrounding surroundings of convincingly darkish shadows. In the event you’re upgrading from a TV (even a dear one) that used to be manufactured ahead of quantum dots turned into mainstream, the QM6K may also blow their own horns extra spectacular colours than you’re used to.
Lengthy tale brief: Except you’re a discriminating videophile, you’re prone to be glad via the QM6K’s shade efficiency.

The QM6K has the chops to offer cast 4K HDR efficiency. The above two components — backlight talent and shade vary — are about 80% of the equation for cast HDR efficiency, with the remainder 20% associated with layout compatibility and viewing surroundings.
The QM6K absolutely helps HDR10, HDR10+, Dolby Imaginative and prescient, and HLG, so you’ll be able to music in to the codecs that use dynamic metadata (Dolby Imaginative and prescient and HDR10+) to maximise your HDR revel in. I will ascertain that during my exams 4K Blu-ray discs graded for Dolby Imaginative and prescient appeared terrific. And with good-enough Wi-Fi, streamed HDR10+ content material appeared nearly as nice — however if you’re making plans to basically circulation dynamic HDR content material fairly than play it from a disc, you may wish to run an Ethernet cable to the QM6K to make sure a constant bandwidth.
One very last thing to notice is height brightness: The QM6K’s height HDR brightness is round 600 nits, which is nice however no longer nice. It received’t knock your socks off when it’s competing with a room filled with lighting or glare from home windows. As with maximum finances TVs, you will have to keep an eye on your room lighting fixtures to a point. If you need a TV that delivers shiny HDR regardless of the situation of the room you’re looking at in, you’ll need to spend extra money.
It provides sufficient movement and video processing. Maximum finances 4K TVs are restricted to a 60 Hz refresh charge, which makes motion-related artifacts like judder and blurring extra visual. The QM6K has a local 144 Hz refresh charge, and its basic video processing is slightly nice, making maximum content material glance easy — or, no less than, easy ample. Like a large number of finances TVs, or even many pricier ones, the QM6K struggles somewhat to care for readability when complicated content material (reminiscent of a map, with many strains of more than a few thicknesses) strikes briefly around the display, which can lead to judder, with content material seeming to leap somewhat because it strikes.
That mentioned, sensitivity to movement artifacts differs from individual to individual, and finances TVs like this type have a tendency to showcase movement blur extra regularly than no longer. So should you’re in particular delicate to the impact, you could wish to spend extra for a pricier TV with higher total movement efficiency.
For the fee, this TV is a brilliant selection for players. In reality, gaming could also be the QM6K’s stable swimsuit: Its local 144 Hz refresh charge is, so far as I’m mindful, one thing you merely may no longer to find in the cheap TV till the previous yr or so. With this TV, players the use of an Xbox Sequence X|S, a PlayStation 5, or a PS5 Professional can take complete good thing about the ones consoles’ talent to render video games in 4K decision at a 120 Hz refresh charge. PC players with strong-enough rigs can rise up to 144 frames in line with 2d whilst gaming in 4K, or as much as 288 fps at a 1080p decision.
I used our Leo Bodnar input-lag tester to measure the TV’s 4K 60 Hz sign and located about 14 milliseconds of lag, because of this round 7 ms at 120 Hz or even much less at 144 Hz. So enter lag shouldn’t be an issue. Whilst enjoying on a PS5, then again, I realized some judder throughout some panning sequences, and I discovered that turning off the TV’s Adaptive Brightness atmosphere (in order that it wasn’t repeatedly looking to assess how vivid the TV and my room had been) helped reduce one of the most video-processing difficulties.
The QM6K isn’t as easy to recreation on as, say, an OLED TV, however until you wish to have overall perfection, it is very good for its worth. As Samsung and LG do on their top rate gaming TVs, TCL features a gaming submenu (on this case referred to as Recreation Grasp) that depends on ALLM to kick in when it detects gaming content material. It additionally supplies at-a-glance specifications so you’ll be able to simply resolve whether or not HDR and VRR are enabled and what refresh charge you’re getting.
Finally, should you personal multiple next-gen console, and you need to make use of them with this TV, word that you wish to have to plug them into the right kind HDMI inputs, as best two of the QM6K’s 4 HDMI inputs give a boost to HDMI 2.1 (the opposite two are HDMI 2.0, with certainly one of them reserved for eARC). However two is best than one — if, like me, you personal each an Xbox Sequence X and a PS5 and ceaselessly switch between them, you received’t wish to stay plugging and unplugging cords.

This isn’t the most productive rendition of Google TV I’ve used, but it surely’s higher than the contest. Google TV is our favourite good TV platform on account of its content material agnosticism, cross-app seek options, and basic customizability compared to the packed-in platforms from corporations like Samsung (Tizen OS) and LG (webOS). However this TV is more or less sluggish about it.
Like many TVs on this worth vary, the QM6K doesn’t have the processing energy besides briefly into the Google TV house web page, to briefly and simply switch HDMI inputs, or to go back seek effects as all of a sudden as pricier fashions. Even supposing I desire the structure of Google TV, I’d fairly use Samsung’s Tizen OS on that corporate’s flagship OLED TV as it simply works so a lot more responsively.
Deficient responsiveness is all the time onerous to swallow, as a result of over the years — with reminiscence and onboard-storage bloat — the QM6K will more than likely best get extra slow. Nevertheless it’s additionally some other level of comparability that many consumers aren’t prone to have: I to find this TV’s platform somewhat sluggish out of the gate as a result of I’m evaluating it towards the ones of TVs costing 1000’s of bucks, while should you’re changing a TV that’s 5 to seven years previous, you’ll more than likely to find it delightfully snappy and legitimately tough.
The primary takeaway isn’t to be expecting smartphone- or tablet-level pace from the QM6K’s Google TV platform. Deal with it with somewhat extra persistence than you do your telephone, and also you’ll get to what you need to observe briefly ample. You’ll additionally upload an exterior media participant for a quicker revel in.
One justifiable criticism I’ve is that leaping from the Google TV homepage to some other enter is slower than I would really like. It kind of feels as though the TV rather a lot all of its apps and Google knowledge ahead of “loading” the HDMI inputs, and looking to alternate inputs once I boot it up is on occasion pathetically sluggish. However in TCL’s protection, the QM6K’s far off keep an eye on no less than has an enter button, one thing that different TV makers are regrettably ditching this yr. And you’ll be able to arrange the TV to all the time boot up into the last-used enter.
This TV’s audio high quality is definitely above moderate for its worth vary. Normally, finances TVs supply a two-speaker stereo machine through which each and every speaker has about 10 watts of energy, leading to a somewhat compressed soundstage that lacks nice bass and will make discussion tough to listen to.
The QM6K brings extra to the desk: This TV employs a 2.1-channel machine designed via Onkyo that comes with the standard 10-watt audio system but additionally provides an onboard 20-watt subwoofer, with rear radiators for higher low-end and lower-midrange sound.
I discovered myself appreciating the bump in audio high quality throughout motion pictures and video video games, however it may possibly’t change a nice soundbar.
Flaws however no longer dealbreakers
It’s easiest to sit down entrance and middle with this TV. Because of the QM6K’s aggregate of a standard vertical alignment (VA) LCD panel and the serious dimming and boosting of its backlight, this TV does no longer ship nice off-angle viewing. Discerning audience sitting a number of levels off-center may also understand the backlight operation extra obviously than those that are seated entrance and middle.
A linked factor is the TV’s shiny display: In contrast to pricer TCL TVs, the QM6K has a run-of-the-mill display, so it displays home windows and lighting fixtures, and the ones distractions display up particularly neatly when darker content material is showing at the display, probably shattering the sense of immersion.
To forestall those gloss-related reflections from mucking up your film, in moderation imagine the place you put the TV in terms of home windows and lighting fixtures.
Older and low-resolution content material merely doesn’t glance nice. That can sound evident — sure, sub-4K and particularly sub-1080p content material doesn’t glance nice on a contemporary 4K TV. However the impact is even worse right here compared to top rate TVs.
Something that makes dear TVs dear is they’re fitted with clever upscaling algorithms which were tuned, regularly over a few years, to higher re-create and sharpen guessed-at pixels in content material that isn’t natively 4K. TVs additionally wish to make guesses about shade high quality when upscaling content material designed the use of an older shade house right into a machine in keeping with a more recent one. Dear TVs price that a lot partially as a result of they’re kitted with the vital tech to do this layering skillfully.
The QM6K doesn’t have the ones complicated upscaling skills, so DVDs, elementary YouTube movies, and equivalent lower-quality movies simply don’t glance superb. You’ll nonetheless watch them, however that is some other efficiency house through which observant audience could be all “Egads.”
This TV has typically deficient out-of-the-box calibration. One more reason people are keen to pay extra for TVs considerations shade calibration: Does the film or TV display you’re looking at glance find it irresistible is meant to, because the colorist or director supposed it on the studio? With dear TVs, it typically does. With finances TVs like this one, it typically doesn’t.
You’ll pass into the menus and use dear meters to tweak the very base layer of a TV’s efficiency to succeed in a extra correct symbol (a procedure referred to as TV calibration), however nobody who’s purchasing a $500 TV needs to do this, and I don’t blame them.
Numerous inexpensive TVs skirt the issue via together with an image mode referred to as Filmmaker Mode, and this yr TCL in any case added Filmmaker Mode to its extra reasonably priced fashions, together with the QM6K. Filmmaker Mode is going some distance towards making the image glance “proper” via turning off movement smoothing, atmosphere a hotter shade temperature, and lowering synthetic processes reminiscent of polishing and video-noise aid.
The QM6K’s Filmmaker Mode is via some distance this TV’s maximum correct image mode, however the implementation fails to fulfill the error-tolerance ranges of Filmmaker Mode as dearer TVs make use of it. This mode additionally significantly lowers the TV’s same old SDR brightness, right down to round 130 nits, so if you wish to watch a correct, cinematic image, be ready to dim the room lighting.
Really helpful settings
The QM6K appears to be like maximum correct (learn our TV purchasing information to look what we imply via “correct”) within the Filmmaker Mode, however whilst you’re looking at in SDR, that mode is meant for both midnight viewing or a extremely managed surroundings with little to no competing lighting. If you wish to punch up the brightness and shade saturation throughout sunlight hours viewing, I like to recommend switching to Clever Mode, which forces content material right into a closer-to-HDR point of brightness and shade. It’s no longer as correct, but it surely nonetheless appears to be like nice.
For HDR viewing, we suggest the Dolby Imaginative and prescient IQ mode (when to be had), because it attracts a nice steadiness, maxing out the brightness and shade with out utterly ditching makes an attempt to be correct (à los angeles Bright or Dynamic image modes).
All the way through preliminary setup, you’ll see a advised to activate Computerized Content material Reputation (ACR). Google TV typically calls this “personalised commercials.” You’ll to find this atmosphere later in Settings > About > Prison Data, and there you’ll be able to flip off personalised commercials. In the event you’d fairly see an outline of your knowledge on your whole Google merchandise, you’ll be able to pass see this data on-line thru Google’s My Advert Heart.
