TCL C6KS (also known as C69KS and Q6CS) is a television that on paper promised to be a hit in the "value for money" category. Indeed, in many respects, it is a successful piece of equipment: thanks to Mini-LED backlighting, we get good blacks and brightness that competes with more expensive models. In fact, it is identical to the slightly pricier C6K model that we have already tested for you. Additionally, it features the same excellent Google TV system and surprisingly rich gaming features that make it enjoyable to play even with a 60 Hz panel. Unfortunately, the overall impression is tarnished by the performance of the panel used. The television struggles with noticeable motion blur, and aggressive dithering (digital grain) causes the image to often appear unnatural and artificial – as if it were being overly sharpened. Ultimately, the biggest problem with the C6KS is not its flaws, but its sibling, the C6K. At its current price, this model finds itself in a strange "middle ground." It costs almost the same (or slightly less) as the fully-fledged TCL C6K, which offers a significantly better 120 Hz panel and is simply a complete construction without those annoying errors. The C6KS is a compromise model that will only become attractive under one condition – if its price drops drastically. For the moment, a significantly safer and better option remains paying a (often nominal) premium for the C6K model. One could cynically state that the letter "S" in the name indeed stands for "Slim." Only it does not refer to an exceptionally slim chassis, but to how much this model has been "trimmed" in terms of features compared to the full-fledged C6K.
The idea behind The One has hardly changed over the years and with the Philips PQS9001 this is both a strength and its biggest drawback. You still get a versatile mid-range television whose main distinguishing feature is Ambilight. The light that follows the picture can change the atmosphere of an evening viewing and for many people will be the main reason to buy it. It's easy to see why: once you like that effect, you often don't want to go back to watching without it. The picture quality itself is good, but a very similar level has been seen in this series in previous years. The VA panel delivers decent blacks, colours are nicely saturated and the brightness is sufficient for comfortable viewing in a typical living room. It's a pity, though, that Philips didn't take another step and at least implement some form of local dimming. In a dark room you can see a navy-black rather than true black, and HDR, though noticeable, is less impressive as a result. After so many years of The One on the market we'd expect more.
There is a clear step forward in Titan OS. Compared with last year, and especially the version from two years ago, the system has become much more pleasant to use. A few apps have been added, many small functions improved and the annoying bugs we complained about before have been fixed. Overall it runs respectably, although we're again bothered by a remote that has to be pointed at the television. Philips stubbornly sticks with infrared for basic control, even though voice control uses radio connectivity. That makes it harder to understand why radio wasn't also used for menu navigation. The One also has a lot to offer gamers. Four HDMI 2.1 ports and extensive features are one thing, but what impressed us most was the panel's response time. Our unit showed virtually no smearing, even on dark backgrounds, which is rare for LCD TVs with a VA panel. That deserves considerable praise. The ability to play in 4K at 144 Hz or in Full HD at 240 Hz further encourages connecting a PC. Unfortunately there's an unfinished element here too: Dolby Vision when gaming on Xbox incurs very high input lag.
The PQS9000 therefore leaves mixed impressions. It can surprise with excellent motion handling and shows that Philips has worked on the system, but the image quality lacks a similar step forward. This is a television we can recommend primarily to Ambilight fans. If that lighting is what convinces you to choose Philips, buying The One makes a lot of sense. It's worth checking, though, whether you can't find a Mini LED model with good local dimming at a similar price, which would offer deeper blacks and more striking HDR. Then you need to decide what matters more to you: the ambience created by Ambilight or better image quality itself.
