Hey everyone! Important notes: This TV is currently over-brightening content and TCL is not only aware, but working on a fix. If you look at the Calman charts, the color temp in greyscale is fine, and the colors hit their coordinate targets fine, but the issues are in the luminance, where they are brighter than the target. Thanks to a tip from Classy, I was able to confirm the TV does not do this in Game mode. Furthermore, turning off local dimming corrects all luminance errors. I have the fix for the luminance shift bug I showed in hand, and will be reporting the fixes once completed. The good news in all of this is that the hardware is fully capable of accuracy, the new AIPQ processor used here just needs to be updated to target accuracy if that’s what TCL wants. That the Tv simply overbrightens beyond spec is not the worst thing in the world, as it just comes off more vivid, but without white balance or colors looking off. Still, for $20K, it needs to have one accurate mode outside of Game mode, and that’s what I hope to see.

I built my dedicated room around the LG 97 G2 and have been absolutely loving it. If this was released at the same time I would have seriously considered it though. What a time to be alive!

THANK YOU!! Putting that 65” tv in front really shows the scale of this tv. AMAZING!!!

[Spealer]

10:12 You really made that 65 Inch TV look like a 27 inch monitor lol

Im an electrical enginieer and can help you with the heat question: It's totally easy for any TV, or any electrical device for that matter. Near ANY electrical power you put into it from your wall outlet ends up as heat in your room (minus the light energy that goes out the windows, but that's not much). So you can just buy a cheap energy-messuring socket and take that value (W for the power (energy-stream) or kWh for the total amount of engery for the entire movie (if you reset that value to 0 before staring it).

The 115" QM8 is $20, 000 - the 98" QM8 is $5, 000 ...

[Kurtiscott]

The liability issues you pointed out (limitations of low res content on such a huge display) was such a valuable insight! Very much appreciated sir

[LeezahB]

Thanks for a thoughtful, honest, yet enthusiastic review!

[jb]

Thank god it's $19, 999 and not $20, 000. I can buy 2 of them now.

"...laying down your credit card." More like calling your bank to wire the money over! 😂

[emziemann]

Might have to get this for the bathroom!

On the topic of how much heat it puts out, the objective metric would be to talk about how much power this TV consumes while watching content, and compare that to the power of a smaller TV. Power consumed is mostly converted to heat, and some is converted to light and sound.

I remember in 2013 I bought a 55 inch tv for my apartment and thought how massive it was. Boy was I mistaken. 70 inch TVs today are the old 55 inch TVs.

That’s exactly how good my R635 from 2020 (TCL) has been. Thanks to you because I bought it because of you.

Size = cinematic immersion. Always choose size over everything else. I had quite a size journey myself: for years used projectors and had wonderful 100", then got jealous of TV features and moved to a 77" OLED, and then realized how much I missed the big size, so now I'm at 83" OLED but still feel deprived of a few inches. :)

For a large part of the country these heat concerns are ridiculous. If I spend a little more on air conditioning I save a little more on heating in winter.
Besides, when I used to watch the yule log channel on my 50 inch Sony plasma it FELT like a fire place too ! Now that's realistic.

[Pete.across.the.street]

I wish they would just leave the speakers out and knock a couple grand off the price. Most people use an AVR and much better speakers anywways.

[roco]

Depending on its price, the Hisense 110” UX I think that’d be the better option at least on paper 🤔 5” smaller but 2x the dimming zones

[aread]

I think for crappy or old content, you should be able to scale the image down to 1080p's worth of pixels, and have a MASIVE black border.

When I saw TCL 115 in the description for your video I got excited. I have two TCL 75 inch tv's that are about 3 years old and thought. Well, it's 40 inches bigger so maybe it will be around the $3000 mark as my 75 inch tv's were incredibly well priced. That was a HUGE whoops for me lol. Looks great though.
