Q: I am asking specifically about the 75" 75R646. Which HDMI ports are capable of 4k @120? Which HDMI ports supports eARC?

A: The HDMI 1 & 2 ports support 4k/120 (HDMI 2.1), one of which also features eARC. Hope this helps! Thank you, TCL Customer Support

Q: Is it true the the pair of stands have two installation options: narrow spacing and wide spacing? For each option, what is the distance between the pair of stands? Note: i have a small TV table about 40 inches long but this TV is 66 inches wide. Thanks!

A: For this 75 inch TCL TV, there are actually 2 different options for feet placement. At the wider position, the feet spacing to fit on a stand is 51.7 inches. At the more narrow position, the feet spacing to fit on a stand is 18.1 inches. You would simply choose whichever option would best fit your home setup. Hope this helps!

A: TCL proudly uses high performance VA Panels on all of our sets to deliver the striking contrast our sets are known for. In fact, being vertically integrated means that not only are the VA panels ours, but nearly everything on the set is TCL, ensuring great quality and performance! Hope this helps!

Q: When will this model be released?

A: I reached out to Best Buy support on October 5 or 6 and they said 3-4 weeks according to their system.

Q: When will this be available and does this have full array back light dimming like the 2020 model?

Completely Blown Away by this picture.
So there was something about this TV on the end cap that grabbed my attention. The aesthetic of how thick it was and the fact that it's the only mini LED TV on display at Best Buy where you can't see blooming from the backlight. Now with all that being said I'm coming from a 2015 LG OLED so I'm used to the best picture but I did want to go bigger and felt confident that TCL has come a long way. And my God turning this TV on, I was shocked at how close to OLED black this TV gets. The color is incredible, HDR looks great, and the brights are so bright that the maximum that I can put this TV on is maybe 34. I'm a big fan of Google TV and the picture options on this are really great but there is a reason I gave it 4 stars. That reason being the software itself is very buggy, there needs to be some software updates because there are several options in the menu that just simply don't work. Such as CEC HDMI control. The moment I plugged my HDMI sound bar into the arc Port which my $1,000 Sony HT nt5 Soundbar supports, the TV's sound came out through my soundbar but with CEC enabled on the soundbar, when you raise the volume you're only raising the TV's volume and not the Soundbar itself. It's also not controlling or moving anything on my Xbox PS3 or Blu-ray player, again CEC is enabled on all of these. The other part of the software that is surprising is if you're playing HDR or Dolby Vision video and try to press the settings button, it just lags and everything freezes and it takes forever. This is odd because the settings for the television should be completely separate from the Google interface that you're streaming from, but it almost feels like it's all one and that's not good. Now, I may be using an external Source such as my Xbox for media content but I really shouldn't have to, so hopefully future updates take care of this lag and CEC issue. On another note, hbo max WILL NOT play any Dolby Vision content, it completely freezes. Also if your watching TV & use the built in guide, there are options to use green & yellow buttons, which ARE NOT present on the remote itself. I do see that some people have gotten bad panels here and believe me, that's a thing with every single brand but I got lucky getting this open box and having a completely white screen, no clouding issues and perfect blacks... as perfect as they're going to get on an LED. If you're curious about the capabilities of mini led, this is the TV to get.

Near OLED at a fraction of the cost!
Okay, I have to write this as there are very few reviews right now and they seem skewed. I will admit that the Google OS takes some getting used to, but let's just talk about the TV itself. If you hate the OS, buy a Roku or Apple TV. Boom, problem solved. But let's just talk about the picture. Look, I'm aware this isn't an OLED. I'm also aware that this was literally 1/3 the cost of one at the time of this review... So let's be clear and keep these reviews in check, shall we. Even at 1/3 the cost, this feels like it could be on display at Costco and it would make you stop and go oooohhhhh! The picture is absolutely phenomenal. My PS5 shines, anything narrated by David Atenborough will make you want to pause and take pictures and send them to your friends to brag, the blacks are inky black. Yes, a (very) little light bleed here and there, but unless you get an OLED that's inevitable. In most cases its even better than what my natural eyes see anyway. No color or gray/black uniformity issues as others have mentioned. Pictures look nearly 3D and the depth of every picture is enhanced 3X more than I've had in my home before. I know roku has a hit or miss track record, but I own 3 from multiple years and have had nothing but great experiences with them. Give it some time. Tweak the settings. Set local dimming to low and turn off all motion controls. Just let the TV do the work that you bought it for. Turn off all the bells and whistles and Up's balloons will plaster your room in colors before throwing you into a dark storm. Contrary to an OLED, I had to turn my brightness way down. 60 out of 100. Adjustable brightness sensors help... But there will be no issues showcasing this in a bright room! Pictures taken by a phone can never do justice to what you see with your eyes, but here's a few anyway... I would easily buy this again and can firmly recommend it!

Great TV, OS still a work in progress
First of all I want to mention the picture. I have not calibrated this tv, have no skill in such things, and have just used presets with minor tweaks to my taste and must say that it looks fantastic. Also there are a smart settings where it will automatically pick the best settings based on content and in room lighting that seem to work pretty well. I'm coming to this from a 8 year old Panasonic Plasma and the black levels on this get closer to that than I ever would have imagined. I can't compare to OLED as I've never owned one. After a few days of owning this TV I began to notice the dirty screen effect in 5 or 6 vertical stripes crossing the TV. This was only noticeable sitting off angle a bit and not very much when viewing directly in front. I loosened the screws to the mounting bracket and also a few other screws in the back of the TV. I didn't notice any difference immediately but over the course of a week I realized I was not seeing the dirty screen effect anymore or at least enough for me to notice or even pay attention to it. I'm not sure if it was the screws loosening or just the picture settings I'm using, but I am no longer worried or bothered by the dirty screen effect as I no longer notice it while viewing. I included a couple pictures with the dirty screen effect and then after when it seems fixed. I am now very satisfied with the overall picture quality, however the Google TV operating system is still a work in progress. All of the issues I've experienced with it have happened while using the quick start option. When not using that option I have not noticed any issues with the Google TV. I've had the menus freeze so I can no longer do anything, lag, apps struggle to launch. Pretty much everything others have already described. I feel like the Google TV does not have enough memory or processing power to handle things or it just cannot clear its cache of information and becomes overloaded until it eventually crashes. Once again this is easily avoided for me by disabling the quick start option and just have the TV do its long startup. It's not as convenient or fast as the quick start but avoids any issues. There was an update a few days ago (week of 12/22/21 so the Wi-Fi no longer drops after quick start, but it's still freezing and crashing if the quick start option is used. I'll update if a software update ever fixes this. So is this TV worth it? That depends if you are able to get rid of the dirty screen effect and don't mind the long startup time by disabling quick start. To me those are the two major drawbacks. If my dirty screen effect was as severe now as I when I first got it I probably would have returned this television by now since once you see it, it's hard to unsee, and would have annoyed me every time I watch something. However, having that resolved, I would say it's a great value for the money for a 75 inch screen and I have enjoyed my time using it. I've watched a variety of different content and played a handful of video games on it and have had a good experience across the board. If you want to a very large screen for a much lower price than the name brands give this a try. If you decide it's not for you Best Buy has a very consumer friendly return policy which makes it easy to refund or swap it out for something else.
