It seems this TV is permanently on sale ever since the new generation came out and the new price is fantastic. Bright colors and very inky blacks for a non-oled TV. HDMI 2.1 is perfect for using this for gaming if that's what you want. I don't have much to say about the built in speakers because I have my own stereo setup but I feel most people spending over $500 on their TV will buy a soundbar or stereo anyways but the little I did use them they sounded alright. The 120hz is fantastic and there is little smearing however light does bleed around bright objects on dark backgrounds but thats to be expected on a TV from this proce range, along with the meh upscaling. The TV does get slow after a while and that can be fixed by turning off fast start or whatever it's called because by default, instead of fully turning off, the TV only goes into a sleep mode which eventually fills up it's system memory. Hoelwevr turning off fast start the TV fully turns off which clears it's RAM and it runs like new each time it's turned on. I've only had the TV for almost a month so not long enough for a super comprehensive review but those are my thoughts.

I did a lot of research before picking this Tv a few things that surprised me , Reflection handling isn't as good as Rtings reviews say.. Yeah it defuses light but it makes this weird star effect when doing so.. (pic below) The viewing angles are much better than in the Rtings reviews say.. I'd say even at around 50-60 degrees still watchable.. The processing.. I really wasn't looking for this when I picked it.. But surprised me on the 5 series lots of old low res content was basically so ugly it was unwatchable.. This Tv does a good job cleaning it up and removing pixellation.. This is a must have if you like to watch old TV shows from the 90's like I do... HDR pop ,3D effect is great once you get the Tv settling dialed in.. but I expected that... since it has good brightness and miniled. I got this as an upgrade from a TCL 5 series from the same year (s546).. The choices were this , u7k , TCL Q7 or the OLED LG A2. I went with this mainly because it was the cheaper option out of all of these. but also because all the other Tv's have some major weakness I couldn't look past. The TCL Q7 has great constant but it brightness and color volume is very similar to the 5 series so not a good upgrade. The OLED A2 was 50% more money.plus it's a very dimm Tv that's bad at handling glare.. Also a deal braker for me since I need a Tv for daytime viewing. The U7k was the closest but it has banding issues.. weak native contrast but better contrast with local dimming.. Plus cost more money.. The R646 was the only one that had good everything across the board.. So while it may lose to the other Tv here and there . (even loses to my old 5 series in terms of contrast alone) Overall it's a better overall Tv. You really can't get a better overall Tv without paying at least x2 as much...

I have seen test results that show the TLC 6 Series/R646 2021 as the fourth-best TV TLC has produced. I used what I learned from those results and bought the TCL (R646) brand new from Best Buy for $399. The information I received from those test results was spot on. The information I got rated it an 8.0 for mixed usage, an 8.7 for gaming, an 8.4 for PC use, and an 8.1 for HDR movies. A rating of 7.5 or above is good to excellent. The picture colors and contrast are great with Dolby Vision, and the sound is immersive with Dolby Atmos. The dark contrast is excellent for a non-OLED TV, and there is no worrying about image burn-in. This TV has advanced gaming features like variable refresh rate (VRR) support and two HDMI 2.1 bandwidth inputs. It's designed to take full advantage of the Xbox Series X and PS5. The HDMI 2.1 bandwidth for 4K @ 120Hz is perfect for gaming with low input lag. Lastly, watching HDR content is impressive because it displays a wide color gamut and gets bright enough to make highlights pop. The price was 20%- 40% cheaper than anything I found, with specs and image quality close to those I just described. BEST DEAL FOR THE PRICE. Best Buy even refunded me $30 when I found a cheaper price online. I have had it for 15 months with no problems and am very happy with my choice. Thank you, Best Buy

Awesome TV couldn't have asked for anything better for a TV. It is very impressive with good brightness contrast sharpness and clarity. I'm not sure what other people are complaining about the OS not being responsive or glitchy but it's really fast I downloaded the update right out of the box and it has been working smooth for me. Not broken screen or DOA. The TV is impressive for the price. I've seen TVs with OLED as well as I own a phone with OLED. With this TCL model you can't really tell it's not an OLED. It tricked me very good that's how good it looks. The blacks are, black. A plus for the mini LED technology and I would say awesome Dolby vision. The only issues I had with it so far is connecting my laptop to the TV it via HDMI 2.0. I tried to connect and disconnect various times to no avail. This happens randomly. To where I'm playing steam games. And signal gets lost. I hope it's not a faulty TV. But I'm suspecting it might be the TV input. Or it can be a faulty HDMI cable that I have? I ordered a HDMI 2.1 cable to see if this resolves the problem. That is my only gripe with this TV out of the box. It worked for a while then it stopped. Unless it's my laptop? Frustrating. Otherwise a good TV.

Had the TV for around half a month and I am impress and amazed. Probably one of the best TV on this price at the $400 deal. Google OS is not that bad as review make it be and is convenient. Being someone that is tech savvy, I really didn't care about the OS and I just wanted the Panel for my PC and PS5. But the fact that I don't have to use my Amazon stick or keep PC on to use steaming apps is a plus. The colors are great out of the box and it looks fantastic compared to my 10 years old 1080P 32 inch TV. Then again it looks better it also looks better than my IPS 40 inch 3440x1440p monitor. When the scene is dark... it really looks dark. MiniLED is the best option aside from OLED without the burning risk and the higher price tag. Due to location of of TV I hardly ever use it above 40% brightness and mostly stays around 28-30%. Can't imagine how bright i can actually get. The 120hz and VRR support were great for the $400 price tag it had. TV barely fits my stand but it does great. Also Had to buy a TV stand as I needed the to be able to swivel it as well as to get a bit space under for the Soundbar. My only grime is that it only has 2 hdmi 2.1 with 4k 120hz support and one of them is for ARC too. Had to hook the sound bar with optical instead as I didn't mind having to use two controllers but didn't wanted to loose the other port. I had to go like through 12 HDMI 2.1 cable to find one that worked as intended ($20 per 10ft cable... -_-... don't cheap out on cables) Also I had and issue with VRR which was fixed. Using VRR would make screen stutter when trying to output higher than 60hz and then loose signal. Same on PC as screen would flicker on an on until change to 60hz. This happen the next day after testing and using it perfectly. Seem like update mess up the settings . I reach out to TCL about it they provided some steps to test and fix the issue. I just couldn't had imagen removing all cables and Powe cycling fixed. I Powe cycle everything but the TV as it had been installed just the day before Since then I haven't had this issue anymore.
