Correct. Hisense International's decision making about 120Hz and HDMI 2.1 decision for international units is stupid. But what can you do.

On the other hand, 120Hz is not really necessary. 60Hz panels that can handle 24 fps have been around since the early days of 720p LCD TVs, which is some 15 years ago. 120Hz panel makes the process of smoothing the judder a little easier. Basically, the world didn't go blind or mad with 60Hz panels.

Gamers who play competitively online know that, at least with current GPU/CPU capability, they can't have the 120Hz 4K experience with all the texture details. 120Hz in 4K with low details, that's possible. It's like gaming in 720p vs 1080p in 2006.

Meanwhile, at CES 2022 Hisense announced some interesting stuff. The new TV models won't arrive until May or June this year.  If Hisense International is predictable, only North America will get the best models with the best tech and the best prices.

Nope. You can't play at 120Hz at 4K. This is a similar situation back in 2006 with PS3 displaying games at 720p and upconverted them to 10800p while the PC version displays it natively at 1080p. Except that most games on PCs can't do 120Hz in 4K and show high level of details and apply ray tracing anyway. If you intend to play competitively at 120Hz, get a 120Hz monitor.

MEMC stands for Motion Estimation, Motion Compensation. Most TV are shot in 24, 25 or 30 fps. Most films are shot in 24 fps. The U7G, and probably most other mid- and low-end TVs, have native 60Hz panels. MEMC creates frames in between the gaps of 24 fps into 60fps. They are not actual frames from the original content, just an estimation and compensation. The MEMC chip can create fake frames at 120Hz but the U7G panel can only display half of them.

You do not want to enable MEMC if you want to play well on the PS5 as it creates lag. Creating fake frames is not the fastest operation. Best set the U7G in Game Mode and ALLM, and play at 60Hz.

Couch coop TV requirement is to get the biggest TV within your budget. PS5 Doom in 120 fps would be nice but not with the U7G, at least the international version.

If you have the budget for a 65" X90J, then go for that.

Hisense 2021 lineup is not for the high-end 4K market. They left that to go with 8K TVs and I don't know if that strategy is working for them. The U7G is for the mid-end market, for people who want quantum dot, FALD panels but not pay through the nose for it.

Many professional reviewers have said that X90J have better color accuracy out of the box. For average users, they won't know the difference. Most TVs sold at retail, including the big brands, are set at the Dynamic mode as their retail mode. Most users who set their TVs at home seem to prefer the garish dynamic look.

The X90J has better color accuracy. It doesn't have the quantum dot filter, which means it doesn't have a wider color gamut, for forever. You can't retrofit the quantum dot filter to it. The U7G has WCG out of the box. You can get the U7G professionally calibrated but...

Most people don't know that calibrated TVs are meant to be watched in dim rooms, something not practiced in most living rooms. They also don't know that it's not a one-time thing. In professional settings, TVs and monitors for film/TV production work are meant to be re-calibrated every 3-6 months. If  professional equipment needs recalibrating, consumer grade equipment needs them too.

So what does this all mean? If you label yourself as demanding color accuracy, you need to tinker with your TV. Get a colorimeter - they usually come with the proper software -, find out your TV's secret menu and calibrate according to the schedule. If you are just an average user, you can use the AVS HD 709 videos and a blue filter to calibrate your TV.

If you just care about brands and models, then a mid-end Chinese brand is definitely not for you.
