Beautiful picture! Excellent TV!
||Posted .Owned for 1 month when reviewed.This TV looks and works great. It upscales HD & 4K to 8K seamlessly. There are 8k YouTube videos available that blow my mind with the color and clarity. It also has some of the deepest blacks I’ve seen on a TV. I’ve recently cut cable, so the integrated Roku app fills the gap for my streaming services. My one real (yet minor) complaint is that the remote is IR-based so the remote needs line-of-sight to the receiver where most Roku remotes use Wi-Fi. It also works with my Xbox One with almost every video setting maxed out. I say almost because I had to disable “allow variable refresh rate” on the Xbox due to flickering issues. Other than that, it looks and plays beautifully at 120hz in HDR or HDR10. It also looks and plays beautifully in Dolby Vision.

Go Buy It!!!!
||Posted .Owned for less than 1 week when reviewed.I bought this on sale for $2699 after reading many reviews and researching information about it on YouTube. This TV is incredibly awesome during all viewing activity especially gaming. I wish my local Best Buy had one on display because they’d sell twice as many of these over Samsungs 8k. TCL continues to step up their game.

High Quality. Well worth the price.
Posted .Excellent picture. Upgraded from a Samsung UHD curved tv. Picture quailing is the same as the Samsung 8k that we saw in the store. Very happy. Love the Roku. Only bad is it is heavy, about 85 lbs. but still well worth it. Like the picture adjustments for movie, sports, etc. you can see the sweat on football players. Excellent tv.

a disappointing tv
||Posted .Owned for 2 weeks when reviewed.I had a bad experience with the TV I was using it as a monitor to play in 8k with an rtx3090, when I entered a game to play in 8k the image started flickering and I restarted the TV I made a different setting I could never run the 8k stable in game and the TV must be viewed from the front because the image when viewed from the side loses quality of focus, very noticeable, I had to return it.

Value for money but as great as expected.
||Posted .Disappointed that I was asked to take credit card option before purchase to avail 10% discount then price match caused further problems. None of the options worked. Value for money but 8K innovation is not matched with other brands. Looks like old technology in the TV as Roku contract is no more available. Somehow I liked 4K mini-led QLED in same 6 series is better with Google TV. Dolby Atmos speakers and in built woofer was not really good.

This compares WELL to our OLED
||Posted .Owned for 4 months when reviewed.This an amazing 8k tv for the price. We have two LG OLED TVs in addition to several other TVs which are actually 4K and non-OLED . This is easily the best TV picture quality wise next to the OLED especially with the 8K outside of the infinite contrast ratio for OLED it does get close but it certainly can’t match an OLED. THE 8k upscaling is awesome!! We have watched plenty of movies and games on it and compared it to the OLED as well as the other TVs this is definitely our go to.

Q: QuestionWrong price?
Asked by Wisealma.
- A:Answer So TCL in their own posts show Best Buy is “KNOWINGLY” cheating customers by charging $1000 over the Suggested Retail Price on this 75” TV. They are overcharging by $400 on the 65” version as well. Pretty Pathetic Best Buy! I’ll also bet BB won’t allow this answer to be posted.
Answered by GetReal
