TCL 6-Collection 2020 Roku TV assessment: Mini-LED makes a giant distinction

The brand new TCL 6-Collection Roku TV has huge sneakers to fill. For 2 years operating it has been my favourite TV for on a regular basis consumers, with glorious picture high quality, class-leading smarts and an inexpensive value. The 2020 model provides a brand new backlight system powered by mini-LED, improved gaming options and a 75-inch dimension, but retains the price inexpensive. The result’s the most effective image high quality for the cash I’ve examined this 12 months.

These mini-LEDs maximize brightness, main to raised photos in brilliant rooms and with HDR.

And players will admire the brand new THX Licensed sport mode, which serves up quick response time with minimal lag and glorious picture high quality.

TCL 6-Collection Roku TV assessment: Brighter and higher than…


In comparison with the 2019 6-Collection, which remains to be a wonderful TV if you’ll find one in inventory, the 2020 model is healthier in just about each means and price an additional $100 or so on the 65-inch dimension. The brand new 6-Collection is not pretty much as good because the 2019 TCL 8-Collection, nevertheless, which has a fair brighter picture and higher native dimming. Usually there is a huge value hole between the 2 however when the 8-Collection is on sale — because it typically appears to be — video high quality snobs who do not wish to spring for OLED ought to most likely select the Eight as a substitute.

I will replace this assessment when I’ve the prospect to check out extra 2020 TVs — coming quickly — however going into the vacation season the TCL 6-Collection is already robust to beat, particularly as soon as the standard November value drops kick in.

TCL’s midrange TVs have a way more polished look than their funds units and the brand new 6-Collection is not any exception. The slim body across the picture and thicker backside edge are darkish grey textured steel, with refined TCL and Roku logos. Not-so-subtle is the large accent gentle under the central brand — it turns off while you activate the TV, fortunately, however I want there was a method to disable it completely. (Replace: You’ll be able to! Go to Settings > System > Energy and switch off the Standby LED. Due to commenter chazzsubscribe.)

New for 2019 is a dual-position stand leg association on the 65- and 75-inch sizes that allows you to place the legs both out towards the sting of the panel, as seen within the photos right here, or extra towards the middle. Each additionally embrace a cable cozy within the legs that allow you to kinda cover HDMI, energy and different connectors.

Howdy, Roku (now with Peacock); goodbye, HBO Max

I am a fan of Roku TV, for causes I’ve documented extensively in earlier opinions. Here is the brief listing why:

Frequent updates and have improvementsSimple menus with full customization, together with enter namingInputs on the identical house web page as TV appsMore apps (and 4K HDR apps) than another sensible TV systemCross-platform search covers many companies and permits value comparisons

Like different Roku gadgets, the TCL 6-Collection is at the moment lacking an app for HBO Max. HBO subscribers can nonetheless watch HBO exhibits utilizing the usual HBO app, however will not get entry to Max-specific exhibits akin to Buddies or Love Life. The TV does now have a Peacock app, nevertheless.

In a difficulty first dropped at my consideration by a reader, the 635’s Amazon app does not but ship HDR. TCL says Roku is conscious of the difficulty and dealing on a repair with Amazon. I will replace this part when that occurs.

Later this 12 months the 6-Collection, together with different 4K Roku TVs and streamers, will add help for Apple’s AirPlay system, which is already out there on competing TVs from Vizio, LG, Sony and Samsung.

The 6-Collection contains the easy Roku distant with built-in voice management. Roku’s voice perform is not practically as strong as Amazon Alexa, discovered on Fireplace Version TVs, for instance, nevertheless it labored wonderful for searches, app launching, switching inputs and tuning to an antenna channel. If the TV is off, a voice command akin to “Launch Netflix” will flip it on and launch the app.

Mini-LED leads a giant listing of options

Mini-LEDs are, as you might need guessed, smaller than normal LEDs, permitting them to be grouped into extra native dimming zones. Full-array native dimming is one of the best ways to enhance image high quality on LCD TVs. It permits the backlight — the half behind the LCD display screen that gives illumination — to dim and illuminate totally different areas concurrently. Smaller areas, or extra dimming zones, imply extra exact illumination, which in the end will increase distinction, a very powerful ingredient in an excellent image.

TCL remains to be the one TV maker to make use of mini-LED know-how, first within the 8-Collection and now within the 6-Collection, however specs on the 6-Collection aren’t practically as spectacular. The cheaper 6 has round 1,000 LEDs and 240 zones on the 75-inch dimension, whereas the dearer Eight has 10,000 mini-LEDs and 1,000 zones. That is probably the largest purpose the 6-Collection did not carry out in addition to the 8-Collection in my exams.

The 2020 Vizio P-Collection might be the brand new 6-Collection’ closest competitor and it truly has extra native dimming zones than the TCL — 200 on the 65-inch dimension. The Hisense H9G matches the TCL with 160 zones on the 65-inch dimension, whereas different TV makers like Sony and Samsung do not specify variety of zones. 

One other enchancment over the 2019 6-Collection is a real 120Hz refresh charge on all sizes within the collection, which ends up in higher movement efficiency. Like most TVs in its class at this time the 6-Collection makes use of quantum dots that assist enhance colour in comparison with non-QD-equipped TVs. And naturally it helps each Dolby Imaginative and prescient and HDR10 excessive dynamic vary codecs. Nowadays principally the one producer that does not is Samsung.

Inputs are ample:

The 2020 6-Collection helps Auto Sport Mode that engages the brand new THX Licensed sport mode robotically when related to a suitable gadget. New for this 12 months it additionally has variable refresh charge and the power to just accept body charges as much as 120Hz. The latter are each essential capabilities of the upcoming PS5 and Xbox consoles, however hardcore players ought to word that the 6-Collection lacks the power to do 4K decision 120Hz with HDR, as a substitute maxing out at 1440p decision. The Vizio P-Collection and Sony X900H, in the meantime, can deal with 4K/120 with HDR. I am undecided how huge a distinction it would make however I plan to check the brand new TVs with these consoles after they come out.

Whereas the TCL 6-Collection put out a wonderful picture, I am unable to say but the way it competes in opposition to the 2020 Vizio and Hisense units talked about above, since I have not reviewed them but. In opposition to the TVs I’ve reviewed, nevertheless, its total image is healthier than another set that earned an Eight on this class — but not fairly worthy of the 9 I gave the brighter and dearer 8-Collection and Vizio PX from final 12 months, not to mention OLED fashions just like the CX that earned a 10. The brand new 6-Collection nails the fundamentals and appears nice for gaming, however some points with dimming in choose scenes held it again a little bit.

Dim lighting: With normal Blu-ray and different SDR content material calibrated for a darkish room, the TVs appeared very related, and any variations can be robust to tell apart exterior of a side-by-side comparability. Total the Sony confirmed barely lighter black ranges than the TCLs, for a barely much less impactful and contrasty picture, and between the three TCLs the 8-Collection appeared finest by a nostril.

Watching 1917 on Blu-ray, for instance, after the soldier awakens in chapter 13 (1:06:38), the 635’s letterbox bars and shadows appeared more true and extra inky than the Sony’s, whereas I may discern extra of the folds of his uniform and partitions within the background than on the 625. In the meantime the 635 and the 8-Collection have been closest of all, with the one actual distinction being barely higher shadow element on the 8-Collection.

Through the extraordinarily darkish assault on Hogwarts from Harry Potter and the Deathly Hallows, the 635 once more appeared finest apart from the 8-Collection. In comparison with the 625 from 2019 its black ranges have been very barely worse however shadow element was considerably higher, and all three TCLs maintained black ranges higher than the Sony. 

In content material liable to blooming, for instance once I introduced up the playback controls throughout a black display screen, the TCLs all did a greater job controlling the stray illumination than the Sony, which lit up bigger parts of the picture. The 635 did present blooming extra with brighter content material, nevertheless, together with HDR (see under).

Shiny lighting: The TCL 6-Collection is the brightest TV I’ve ever measured at this value. Brighter TVs just like the 8-Collection and the Vizio PX price much more — as do quite a few dimmer examples just like the Sony X900H.

The TCL’s brightest settings, “TV Brightness: brighter” and “Image mode: Vivid,” (or “Shiny HDR” for HDR content material) are terribly inaccurate. An correct bright-room image is laudably straightforward to realize, nevertheless. Simply change the mode to “Film” or “Darkish HDR” mode, which reduces gentle output however delivers a a lot better picture. 

Beneath brilliant lighting the 2020 6-Collection’ TCL’s display screen carried out a bit higher than final 12 months’s mannequin, in addition to the Sony, at mitigating reflections and preserving black ranges and distinction. Total its bright-room picture is simply as spectacular for the value as its house theater image.

Shade accuracy: In response to my measurements the TCL 635’s colour was glorious earlier than calibration in Film mode and even higher afterward. Watching 1917, for essentially the most half I might name its colour glorious as nicely, as indicated by the numbers. It did seem barely much less saturated than the opposite three at instances, for instance, within the faces of the troopers or the reddish glow of the firelight. Usually the distinction was minimal, nevertheless, and in different scenes it was a lot much less seen.

Video processing: The 6-Collection is a 120Hz native TV with loads of choices for dealing with movement. The obvious is Motion Smoothing which has 4 settings. In Off the TV delivers appropriate 1080p/24 movie cadence however within the different settings, Low and better, it causes the TV to have the buttery smoothness of the cleaning soap opera impact.

These different settings, “Motion Readability” and “LED Movement Readability,” have an effect on movement decision and work together with each other. The excellent news is that attaining most movement decision does not require SOE. Once I toggled LED Movement Readability on, participating black body insertion, and cranked Motion Readability to Excessive, I measured a wholesome 1,080 strains of decision — superb, albeit inferior to the Sony or another 120Hz TVs I’ve examined. Turning LED Movement Readability off reduces decision out at 600 strains. I most popular to go away AC on Excessive and switch LED Movement Readability off as a result of the latter dims the picture barely and launched some flicker. Viewers very averse to blur may wish to depart it on, nevertheless.

In comparison with final 12 months the 2020 6-Collection added a pair milliseconds of gaming enter lag, clocking in at round 18/19ms for each 1080p and 4K HDR in sport mode. Twitch players may discover, however no person else will. That mentioned, the possibilities of noticing lag go means up for anyone who does not use sport mode in 4K HDR: I measured 134ms (!) in 4K with sport mode turned off.

“Sport mode” is definitely one other complicated setting on the 2020 6-Collection. You’ll be able to apply it to any image mode (akin to Film) or select the precise “Gaming”https://www.cnet.com/”Gaming HDR” image mode, which invokes THX’s particular sauce. In each circumstances enter lag was principally the identical.

Uniformity: With take a look at patterns the 2020 6-Collection was stable with out an excessive amount of brightness variation throughout the display screen: barely higher alongside the perimeters than the 2019 6-Collection and higher within the center than the Sony. One blemish on my assessment pattern was a pair of very barely darker spots within the center proper. They have been fairly refined: I solely observed them on take a look at patterns and demanding materials like hockey. From off-angle the 65R635 preserved extra black degree constancy than the 625 and the Sony, whereas off-angle colour was much like the opposite TCLs and worse than the Sony.

HDR and 4K video: As common with brilliant, contrasty HDR materials I noticed extra variations than with SDR. To get a baseline I began with the video montage from the Spears and Munsil 4K HDR benchmark disc, and the 635’s benefits stood out over the Sony and the 2019 6-Collection. Within the cityscape scenes just like the Ferris wheel at night time (4:49), the 635’s highlights appeared brighter than the opposite TCL, whereas the black ranges of the sky and shadows have been considerably darker than the Sony. In the meantime the 8-series appeared better of all, with blacks as darkish because the 635 and brighter highlights.

In troublesome scenes with objects in opposition to black backgrounds all three TCLs confirmed related inky black ranges however the highlights have been fairly visibly totally different. The 635 was persistently brighter than both the Sony or the 625 (the pen at 4:12 was an excellent instance) and dimmer than the 8-Collection. In largely white scenes, just like the mountains and the horses grazing within the snowfield, the 2020 635 once more measured the brightest apart from the 8-Collection.

As with SDR the 635’s colour did seem barely much less impactful and saturated at instances, significantly orange just like the sunsets or the wings of a monarch butterfly at 3:51. And identical to with SDR the distinction was refined and the type of factor I would not discover exterior of a side-by-side comparability. And in different scenes, just like the crimson, inexperienced and yellow of the tulip subject, the 635 appeared simply as vibrant and punchy as the opposite three. 

Shifting on to the 1917 4K Blu-ray disc it was largely the identical story, however in a few blended brilliant and darkish scenes that actually take a look at native dimming, the 635 stumbled. When the troopers meet the overall within the bunker (5:20), the 635 confirmed extra blooming and stray illumination within the troopers silhouettes, the shadows and letterbox bars than the others. I attempted decreasing the brightness setting from Brighter (which I like to recommend for HDR on this TV on the whole) to Regular (which put it at roughly the identical total gentle output because the 2019 TCL) and or Darker (the dimmest possibility and far dimmer than both one). If I had to decide on between the Sony’s lighter black ranges and the 635’s blooming, I might nonetheless take the 635, however each of the opposite TCLs dealt with this scene higher.

And as common the impact diverse fairly a bit. Within the subsequent darkish bunker scene, round 25:45, the 635’s blooming was a lot much less noticeable, maybe due to the best way the flashlights and digicam moved by the rooms. Alternatively within the Chapter 13 awakening scene the TCL 635 was principally unwatchable: its dimming kicked in aggressively to crush nearly all of the shadow element within the scene, the uniform and background have been invisible and blooming rampant. Altering the image mode to Shiny HDR reclaimed a lot of the element however made different points of the picture look worse, particularly in brighter scenes. The 625 appeared a bit higher (however not nice) throughout this scene, the 8-Collection appeared considerably higher, whereas the Sony appeared the most effective regardless of its lighter black ranges, displaying minimal native dimming results.

HDR colour throughout 1917 confirmed the Sony because the palest and least saturated of the three on this pale and unsaturated film, and to my eye the 635 and 8-Collection appeared essentially the most balanced. HDR colour accuracy measurements gave the Sony the benefit over the 635.

4K HDR gaming: For this take a look at I performed The Final of Us Half 2 on a PS4 Professional within the TVs’ varied Sport modes: Gaming HDR (aka THX-certified Sport Mode) for the 635, Darkish HDR/Brighter/”Sport mode” toggle on for the opposite two TCLs and Sport mode on the Sony. In my comparability THX Sport mode did a wonderful job of balancing picture high quality and low enter lag.

In these settings the 635 had the most effective distinction, brightest highlights and most punch of the bunch — the opposite three appeared extra washed-out. While you’re crawling round a darkish constructing looking zombies, nevertheless, shadow element is extra essential than black degree and distinction, as a result of it means that you can peer into darkish recesses to identify enemies. By that measure the Sony was higher than the 635, delivering each ounce of element within the darkest shadows whereas the 635 was a bit extra shrouded, albeit nonetheless higher than the opposite two. If I needed most zombie-spot potential on I might set the sport’s Distinction slider a bit decrease.

Shifting out into the day-lit Seattle streets the 635 once more appeared finest total because of superior distinction, which as common helped colours pop. After all you possibly can reclaim the native distinction of the opposite TCLs by turning off the Sport mode toggle however the trade-off is excessive enter lag  — which was insupportable as I performed the sport.
