The X80s doesn't have local dimming. The 90s have local dimming. 65" X90J costs RM7,000. Both models are Android based.

It depends on your requirements - space, budget, features. The Hisense U8G and U800QF are the best 65" model for the features at RM5,000 price level - full array local dimming, 1000+ nits brightness, Quantum Dot with wide color gamut, VA panel and Dolby Vision. You do need to fork out RM220-RM700 for an Android player - Tivo 4K or NVidia Shield - for all the Android features you want.

If Hisense Malaysia had competitively priced the U7G and the U8G, these TVs would be a big hit. If the models could be changed to Android, it would be a really big hit.

I've compared how Hisense Thai do their marketing on Facebook vs how Hisense Malaysia is doing theirs. Clearly they know how to sell while the Malaysian one is slowly opening a Hisense Museum.

To frustratingly reiterate my point, Hisense Thailand has an 8.8 sale of RM3,247 for the 65" U7G and RM4,325 for the 65" U8G. Feature for feature, you can't beat that price.

Well to be fair to Hisense Malaysia on this particular point, the blame for VIDAA is solely on Hisense HQ. North American models come with Android. They should have made the 2021 U series all Android worldwide.

If 65" is too big, then you've locked down one requirement.

The next is the budget and features. Unless you can import the 55" U8G, you won't be getting 1000+ nits brightness from I think most TVs out there at that price point. So then you're working with 700-900 nit brightness TVs.

Sony X90J: Android. FALD. Dolby Vision. VA Panel. 120 Hz panel.
Sony X80J: Android. Dolby Vision. ADS IPS Panel. 60 Hz panel.
Hisense U7G: FALD. Quantum Dot. Dolby Vision. Va Panel. 120 Hz panel.

Once you choose what features that's important, you'll find your TV. Hopefully it'll fit your budget.

HDMI 2.0 can do eARC and VRR. HDMI 2.1 can do 8K, 4K 120 Hz with HDR and ALLM. If your use case needs HDMI 2.1, then you need to do another research. Otherwise, HDMI 2.0 is good enough.
