TCL 6-Series (R655) TV review: dangerously good

While we reviewed the 65-inch 65R655 model, our review also applies to the 55-inch and 75-inch models.

TCL didn’t need to tweak its winning formula for the 6-Series for this latest version to be a big success, but it made a few welcome changes and additions anyway.

The most obvious visual change is the stand. For the R655, TCL has moved away from the feet found on the R646 and R635 from previous years in favor of a center pedestal. I prefer the look and the functionality, at least for now. Eventually, I’ll probably get tired of this look, too. But for now, the center stand is in.

TCL continues to give cable management due attention by placing cutouts at the top and bottom of a removable plastic backing plate, allowing you to funnel cables and wires down through the pedestal and out of sight behind the TV. The only problem I experienced when trying to do just that came when I tried to use a supplied cable clip underneath the backing plate — and it snapped off. The cable clip appears to have been affixed with glue, and perhaps the glue on my review sample had grown weak or was otherwise compromised. Still, I was disappointed that something on a relatively expensive piece of gear snapped off in my hand.

If there are other visual changes, they are so slight as to be virtually unnoticeable. The R655 remains an attractive TV, although, to be fair, it isn’t trying to win any beauty pageants.

Most other changes aren’t visible until you use the TV. The mini-LED backlight system has been optimized for better performance. The local dimming algorithm seems improved. The panel can now serve gamers with refresh rates up to 144Hz. There probably are other tweaks at play under the hood, but TCL isn’t dishing out that kind of detailed information and, really, it doesn’t matter unless the picture quality benefits. And, as I’ll soon discuss, it does.

Anyone who has read my previous TCL Roku TV reviews will find the following criticism a familiar refrain, but this time I’m singing a little bit louder.

Lest you think I’m being apathetic to video enthusiasts who are refused the opportunity to get their hands dirty in the TCL R655’s settings menu, understand that I am one of those enthusiasts myself. I’m the person who, upon setting up the TCL 6-Series at home, will immediately try to customize and maximize the TV’s picture quality. That’s Caleb the consumer, and he’s frustrated. But Caleb the TV reviewer? Well, he’s also frustrated, but he’s got this gem of perspective to share: the overwhelming majority of folks who buy this TV won’t care.

Now that I’m done referring to myself in the third person, let me clarify my point. I understand that the TCL 6-Series is something of a darling among TV enthusiasts on a budget, and those enthusiasts are well within their rights to want more control. But we can’t necessarily get mad at TCL — some of this probably is the fault of the Roku TV platform. And maybe if Roku weren’t so damn popular, and TCL’s Google TVs weren’t so damn buggy their first time around, we wouldn’t have this problem. But we do. And it’s our cross to bear because TCL and Roku are giving the vast majority of the folks that will buy this TV exactly what they want: exciting picture quality and a hassle-free experience, right out of the box.

We, the vocal minority, are sure to be heard, and maybe things will be different next year. But for now, we’ll just have to live with the TCL 6-Series only reaching, say, 95% of its potential.

Fortunately, 95% of its potential looks really freaking fantastic.

The TCL 6-Series (R655) is the brightest 6-Series TV model yet, with impressive black levels, minimal blooming, and dazzling color. Picture processing looks great with decent-quality content, especially in the area of motion resolution. Most folks who purchase this TV will be thrilled with the picture quality.

The R655’s punchy brightness delivers impressive HDR images with bright highlights and arrestingly vivid color. For HDR, peak brightness was right under 1,500 nits, and it was stable at 1,100 nits with the 10% window test. This tells us that its average picture level in HDR can be pretty high — just over the 1,000 nit level if you max everything out — and that HDR highlights will top out around 1,500 nits.  I consider that really good for a TV in the R655’s price range. Are there brighter TVs out there? Yes, there are. But we’ll get to the bright room TV discussion in a moment. 

I measured 515 nits in SDR, but my eyes tell me the TV gets much brighter than that. It can work for daytime viewing, but it doesn’t have much in the way of anti-glare treatment. While this does have the advantage of giving you velvety blacks, the drawback is that it doesn’t do much to handle reflections. If you’re someone who does a lot of TV watching in a sun-drenched room during the day, you’ll need to do some tweaking to your picture presets in order to juice up the image for a bright room, and you’ll have to contend with some glare.

This TV performs extremely well for its price point. It offers solid HDR specular highlights and the local dimming is outstanding for a TV at this price, so you get incredibly deep blacks — albeit with a slight hit to really dark shadow details at times, though nothing to get upset about. Blooming is extremely well mitigated; I would happily put this TV in my bedroom or a dedicated, light-controlled viewing room. The color looks outstanding, rich when it needs to be, and vivid when it needs to be.

I  know a lot of video enthusiasts on a budget want the TCL 6-Series to be the slam-dunk choice of the year, and to be honest, it still is the best choice for them. The frustrations I’ve expressed about the R655’s lack of adjustability come from knowing it has locked-up potential, and that enthusiasts will be equally frustrated there’s no key for that lock. However, for the vast majority of folks looking for a high-performance TV at a reasonable price, the choice is clear: there’s no better TV in this price class than the TCL 6-Series.
