As with all other OLED TV , you want to switch to the right mode and tune down the brightness at first .
This is crucial because a large majority of the content you will be watching are SDR .

Therefore they don't require you to blast the brightness all the way up to 300 - 400 cd/m2 .

Expert - dark room is the more accurate mode . 
OLED light of 20-35 is recommended for dark room , with gamma to BT.1886 OR 2.4 .
40+ for bright living room and gamma to 2.2 . 

Ideally 65" CX1 if you can stretch it.

2.5m is perfectly reasonable for a 65 " 4k screen.
I also have a 55 " A9F which is used exclusively for running test pattern and movies , they are roughly 1.5m away from my seat .
The closer you are to the screen , the larger your vision angles are being stretched leading to a more cinematic experience .
The golden ratio for a 55 " is approximately 1.7m away from the screen , at 36 - 40  degree.  This translates to 2.0m for a 65" .

For gaming and other purposes  , I would add 0.5m to the gap to prevent motion sickness .
I usually recommend people to sit slightly closer to OLEDs than typical LCD because you can actually see how amazing the contrast on self emissive screens are , each perfectly lit-up pixel just makes the experience so much more immersive .
My new favorite Passengers look unbelievable on OLED screen . Lotsa dark scenes with a bunch of small highlights  , my new go-to for Test stressing the PQ of TVs.

Interested with 55” CX
Mind to share where you get the deals from?

I'm torn between 65' X85J and 55' X90J.

Is there any major difference in picture with Full Array LED in X90J compared to X85J?

Yup agree, my 65x90j coming next week😄

Th tv current position is about 3 feet away from bed end. But I sit 2-3 feet while gaming. If movie I will lay back which is about 4-5 feet.

I don’t want to add anymore budget I was trying to get 5k LG C1 if possible.

I went senheng to ask around possible to get x90j for 4.9k

I don’t mind 48 really. 55 I might find it too big for 2-3 feet range.

If you are rich UMNO guy and money no object, A90J (best overall) and G1 (best gaming) are the best

Mine is C1 48, so far no such issue with PS5. (my PC is the one having issues LOL)

I think -1 means 4:2:2 chroma subsampling, not 8-bit.

If it's 4:2:2, then it's quite okay. Our eyes cannot notice the difference during gaming and show.

Well it's not the end of the world haha

4:2:2 is near-impossible to notice in a blind test for gaming and movies.

When I set Ratchet Clank to output 40FPS, it was changed to 4:2:2. Still cantek.

games on PS5 are mastered in 4:2:0.
Perhaps Sony saw no reason to give users to enable 4:4:4 anyway because it makes no difference at the end of the day.

So I was browsing for some cheap tv. I dont mind lack of HDMI 2.1 bcoz my eys are old man one so didn't matter if it was 120Hz all I see was same 60Hz. Is this good enough? Since it got Dolby Vision so its good for my Series X too I think
Hisense 4K ULED Smart TV (55") 55U7G

IPS screen , sadly .
Samsung is really dropping the ball .

Unless it is the 85" , all of them are IPS .

It has been proven beyond a doubt , screen-scanned by me and by our fellow forum mates as well .

Your shop guy probably went online and checked from rtings , and saw the TV with the same models and thought they found the answer .

The QN90A of US is the same line up as QN95A in Uk / Europe , which is not available in Malaysia .

If you want a good (relatively) budget HDR TV for PS5, the Hisense U7G has good enough HDR performance and attractive price point

Note: cannot do 4K 120hz properly

You can definitely tell the difference in very specific scenes .
The problem gets worse when you consider that  Hisense TV does not come with any smooth-gradation features .
This caused some movies filmed with grainy effects a  lot " noisier " than usual due to the lack of " grades " to progress from one to another .
You can get a X90J 55 " for less than 4k during one of these xx / xx  sales , saving 1000 going for U7G just to have sub-par picture quality and inferior FALD system sounds a little absurd to me .

Hisense has also fallen far behind other brands when it comes to picture processing and upscaling .
I hate to tell people they don't have much of a choice here but that is just the fact with the MY TV market .
