The TCL C7K is a very good, feature-packed mini-LED TV that's held back from greatness by a few flaws

TCL C7K review: Two minute review

The TCL C7K has an impressive list of features and delivers solid performance. It will have a tough battle in the market against the best TVs, but it’s still great value for money.

With its dynamic and vibrant colors, surprisingly rich black levels and contrast, realistic textures and minimal blooming, the C7K’s overall picture outperforms its price tag. The C7K’s motion settings will benefit from tweaking, but once that’s adjusted, it's good for sports as well. Unfortunately, the C7K is held back from being truly great due to screen uniformity issues, but these are mostly noticeable with black and white movies.

The C7K’s audio performance is decent, with clear dialogue, punchy overall sound and good connection with the onscreen action. Its bass and soundstage are a mixed bag, however, lacking the impact and immersion you’d expect from a 6.2.2-channel system. Cinema fans will want to invest in one of the best soundbars for the C7K.

The C7K plays it safe with a functional design that’s lightweight yet sturdy, and an adjustable pedestal stand that can make space for a soundbar. Its Google TV smart TV platform is responsive and has plenty of settings, although the large banner ad on the homescreen is an eyesore.

Gamers will be pleased with the C7K’s performance, and its gaming features are up there with the best gaming TVs, especially in the mid-range category. Gaming feels snappy, smooth and responsive, especially for an affordable TV.

With discounts already happening across its many sizes only weeks after release, the C7K is an excellent value for a TV with this level of performance and features. It really does put itself in contention with the best mini-LED TVs.

TCL C7K review: Prices & release date

• Release date: May 2025
• 50-inch: £799
• 55-inch: £999
• 65-inch: £1,399
• 75-inch: £1,799
• 85-inch: £2,199

The C7K is the mid-range model in TCL’s 2025 C-series mini-LED TV lineup. It sits above the TCL C6K and below the flagship TCL C8K. There are also TCL C9K and X11K flagship models, but the company currently has no plans to bring these to the UK from Europe.

Since its launch in May 2025, C7K prices have already dropped for most sizes. The 65-inch model I tested is now available for £1,099 and the 75-inch model is down to £1,349. These will likely be the normal prices going forward. There is currently no price for the 115-inch model.

TCL C7K review: Features

• Dolby Vision & HDR10+ HDR support
• CrystGlow HVA panel
• 4K 144Hz, VRR and Dolby Vision for gaming

The TCL C7K uses a mini-LED backlight with varying numbers of local dimming zones depending on size (the 65-inch I tested has 1,008 local dimming zones). It also has a new CrystGlow HVA panel that's designed to improve viewing angles and minimize screen reflections. The C7K also introduces ‘Halo Control’ technology, which aims to reduce backlight blooming.

There is full HDR support on offer, including both Dolby Vision and HDR10+ formats. There is also support for IMAX Enhanced and, for the first time in TCL TVs, a Filmmaker Mode picture mode.

For audio, the C7K has a Bang & Olufsen built-in 6.2.2-channel speaker array with 60W total power. There is support for Dolby Atmos & DTS:X soundtracks, a number of preset sound modes and an equaliser where bass and treble can be adjusted.

The C7K has a substantial list of gaming features including 4K 144Hz, VRR (AMD FreeSync Premium Pro), ALLM and Dolby Vision gaming. There is also a Game Master mode with Game Board for adjustable settings such as Aim Assist. As usual with TCL TVs, it only has two HDMI 2.1 ports.

For its smart TV platform, the C7K uses Google TV, which has access to the usual streaming apps like Netflix, plus UK-specific apps such as BBC iPlayer and ITVX. There are several settings for picture and sound adjustment, an Ambient Mode for when the TV is in standby, and support for multiple user profiles for greater customisation of apps and recommendations.

TCL C7K review: Picture quality

• Vibrant color
• High brightness for a mid-range TV
• Screen uniformity could be better

The C7K hit impressive brightness levels for a mid-range mini-LED TV in my measurements. In Filmmaker Mode, it yielded 1,790 nits peak brightness (measured on a 10% white HDR window pattern) and 578 nits fullscreen brightness (measured on a 100% white HDR window pattern). And in Standard picture mode, it hit 2,784 nits peak brightness and 678 nits fullscreen brightness on the same HDR window patterns.

This puts the C7K in a similar region to the Samsung QN90D, the brand’s flagship 2024 mini-LED TV, which hit 2,192 nits peak brightness and 735 nits fullscreen brightness in Filmmaker Mode when I measured it.

Measuring the C7K’s HDR color gamut, it hit 97.1% of the UHDA-P3 colour space and 78.4% of the BT.2020 colour space in Filmmaker Mode. These are excellent results for a TV of this price range.

The C7K does a solid job upscaling lower-resolution sources, with an HD stream of Fight Club showing improved textures. For 480p and below sources, the C7K still does a decent enough job, though textures are unsurprisingly fuzzy.

For my testing, I generally used Filmmaker Mode, but those who want a brighter picture could use Movie Mode. I found setting gamma to 2.4 improved contrast, although the default 2.2 looked good as well. Luminance levels can be adjusted in the setup menu, and I found High-light to be the most consistent setting, though Standard also worked well.

Colour is one of the C7K’s strengths. A 4K Blu-ray of Wicked in Dolby Vision Dark mode revealed spectacularly bright and vivid colors in the pink flowers, blue details and Elphaba’s green skin in the Wizard & I scene. The same held for a 4K Dolby Vision stream of Elemental, with Ember’s glass-making showcasing shimmering, vibrant, and deep oranges and reds.

I was also impressed with the C7K’s black levels and contrast. In both Alien: Romulus and The Batman, shots with lamplight cutting through dark hallways not only showcased the C7K’s contrast chops, but also the benefits of its new ‘Halo Control’ feature, which drastically reduced backlight blooming compared to what I’ve seen on other mid-range mini-LED TVs such as the Hisense U7N.

Textures and details throughout my viewing were lifelike and natural. The C7K’s strong contrast also added depth to textures, creating a 3D-like effect.

It wasn’t all smooth sailing for the C7K during my viewing, however. Watching the black and white scenes in Oppenheimer revealed screen uniformity issues, with brown tones seen along the edges of the black, widescreen bars – something I didn’t notice in color movies.

Although viewing angles are pretty good for a mid-range mini-LED, the C7K’s picture still loses contrast and color saturation when viewed from off-centre seats – something to note if you plan to watch with big groups.

I also found on occasion that areas with dense textures, such as a bunch of leaves on a tree, would sometimes lose clarity and look ‘muddied’ although this happened very rarely.

For motion, I found that sports were best viewed in Sports or Standard mode (Sports had significantly brighter colors). Watching a stream of a football match, either using the default Medium motion clarity setting or setting judder reduction to the middle point, and blur reduction to 2 or 3, resulted in a clearer picture.

The same was true for movies. A panning shot of a rocky landscape in No Time to Die revealed high levels of judder and strongly benefited from some motion interpolation. But when using the above settings, the same scene looked smooth without being overprocessed.

• Picture quality score: 4/5

TCL C7K review: Sound quality

• Good placement and positioning
• Mixed bass performance
• Narrow soundstage

The C7K’s Bang & Olufsen 6.2.2 channel, 60W sound system is a significant upgrade over the 2.1 Onkyo system found in the step-down TCL C6K. The C7K features the usual slew of preset sound modes, and I found myself sticking with the Movie mode throughout.

During the Batmobile/Penguin chase scene in The Batman, the C7K’s speakers delivered a convincing connection with the onscreen action, with screeching tyres and crunching crashes all realistically placed. In Wicked, vocals throughout were delivered with real clarity and there was a good balance between the score and the background effects.

I experienced mixed results with bass. The Batmobile’s engine felt impactful in The Batman, but I didn’t hear the same rumble I’m used to getting with the best TVs for sound. The C7K’s soundstage could also feel narrow and contained to the confines of the TV itself. For example, Wicked’s rousing soundtrack never felt fully fleshed out, and the Dolby Atmos effects weren’t very audible.

While most users will be pleased with the C7K’s overall sound quality for day-to-day viewing, those wanting a cinematic experience will want to invest in a soundbar.

• Sound quality score: 4/5

TCL C7K review: Design

• Lightweight but sturdy build
• Functional, practical design
• Pedestal stand

The C7K’s design isn’t going to turn heads, but it is functional and does the job. The TV itself is surprisingly lightweight, but it feels solid when attached to its pedestal stand.

The stand itself is made of a dark plastic and feels a little on the cheap side. It’s a little fiddly to put together, but it can be adjusted for height to compensate for a soundbar.

The included remote is longer and now has a black, metallic finish (as opposed to the silver in the TCL C855), which gives it a more ‘premium’ look. It is still light and feels a little flimsy, but it is not different from the remotes that come with TVs in the same price range.

• Design score: 4/5

TCL C7K review: Smart TV & menus

• Google TV
• Large banner ads on the homescreen
• A good number of picture settings

Google TV provides access to a large number of apps, including Netflix and Disney Plus as well as UK-based apps such as BBC iPlayer and ITVX, and it feels responsive and smooth during navigation on the C7K. A Google login (which is required to access the full range of apps) provides customized content recommendations on the homescreen.

One thing that is tough to ignore is Google TV’s large banner ads at the top of the homescreen, which take up large amounts of space, pushing recommendations and apps further down the screen.

Menus are easy to navigate and there are plenty of picture settings to tweak, including white balance adjustments for picture calibration as well as brightness, colour, clarity and motion. There are also sound adjustments, including an equaliser.

• Smart TV & menus score: 4/5

TCL C7K review: Gaming

• 4K 144Hz, FreeSync Premium Pro and Dolby Vision gaming
• 13.5ms input lag time
• Only two HDMI 2.1 ports

The C7K’s gaming features include 4K 144Hz, VRR (AMD FreeSync Premium Pro), Dolby Vision gaming and ALLM, as well as a Game Board for settings adjustments. This is a stacked list for a TV of this price range.

Gaming performance is very good on the C7K. Playing Battlefield V on Xbox Series X, battle sequences were well handled and targeting and combat felt responsive and reactive to my input. The C7K measured a 13.5ms input lag time, a respectable result that is under the 15ms threshold most gamers look for.

The C7K only has two HDMI 2.1 ports, whereas TVs from brands other than LG and Samsung TVs are starting to catch up on that front. The new Hisense U8QG has three HDMI 2.1 ports, for example.

• Gaming score: 4.5/5

TCL C7K review: Value

• Excellent features for the money
• Fairly priced for the performance
• Better mini-LED TVs will cost more

The C7K is reasonably priced considering its stock of features and overall picture performance. The 65-inch model I tested is now widely available for £1,099, and its closest specced competitor, the Samsung QN80F, costs £1,699. We haven't tested that TV yet, but it’ll have a mountain to climb to justify the £600 price gap.

If you’re looking for a more budget option, the C6K is TCL’s entry-level mini-LED, with its 65-inch costing £799, though you’re sacrificing features, audio and local dimming zones.

The Step-up C8K will cost you £1,599 (though this is likely to drop). Here, you’re getting improved performance and more features and local dimming zones, but you’re paying quite a bit more for it. The C7K does prove itself to be the sweet spot in the C-series range.

How I tested the TCL C7K

• Subjective viewing tests made using HDR and SDR sources
• Tested in TechRadar's testing room for over a week
• Measurements made using Portrait Displays' Calman color calibration software

I spent the first portion of my testing by doing some casual viewing to establish the C7K's most accurate picture modes, landing on Filmmaker Mode for SDR and HDR sources and Dolby Vision Dark for Dolby Vision content. Movie and Dolby Vision IQ were also good alternatives.

I conducted my subjective viewing tests using both SDR (HD and low-resolution) and HDR (4K Blu-ray and streaming) to analyse the C7K's picture quality, focusing on colour, black levels and contrast, detail, motion handling and upscaling.

I used these same reference discs to analyse the C7K's built-in sound quality as well.

For objective measurements, I used a test pattern generator and colorimeter and recorded the measurements with Portrait Displays' Calman colour calibration software.

I analysed the C7K's brightness using SDR and HDR white window patterns from 1-100% in size, focusing on 10% (peak brightness) and 100% (fullscreen brightness) in particular.

I also analysed the C7K's SDR grayscale and colour accuracy, averaging out the Delta-E values (the margin for error between the test pattern and what's shown on screen) for both.

I measured HDR colour gamut coverage for the UHDA-P3 and BT.2020 colour spaces, which reveals how well a TV can display the extended colour range in HDR sources.

Finally, I analysed the C7K's input lag time using a Leo Bodnar 4K HDMI Input lag Tester.
