Yes
Worst - global dimming
Ok only - local dimming
Not bad - full array
Best - oled

You can throw away global dimming tv.

No of course not, some mid range TV can do decent too .  The primary factors of HDR performance of TV are mostly the following :

brightness ratings across different APL ,
the local dimming system
the color performance ( coverage and volume )
native contrast ( black levels performance in particularly )
With the technology we have today , as long as it ticks 3 out of the 4 , it should be considered as a good HDR experience.

Hi Guys,

Between Sony Z9D (65") and X8500E (65"), which would be a better choice given that the X8500E is 2017 product vs Z9D being a 2016 product. Any downside to Z9D in terms of technology? Have a friend offering to offload his good condition Z9D close to the X8500E price, so seems like a good deal on retail price itself.

TIA.

I wouldn't call X900F a mid range models , because of the pricing and size availability in MY, which is a shame because it is a really good TV.
Rumor is that Sony is planning to release the successor of A1E and Z9D within the year , again the price will probably shoot through the roof and remain out of reach for typical consumers .
Regardless , I do have a few Mid-range models in mind .
Since you specifically mentioned HDR , I will only emphasize on the VA Panels because of the contrast advantage .
Samsung NU 8000

Base on the pricing and models , this is my personal pick for the best mid range 55/65 VA panels in MY at the moment.

It has all the features you need for a decent HDR performance .
From Local Dimming ( edge-lit , not very good but better than nothing ) , Wide Color Gamut , excellent SDR brightness , above average HDR Brightness , good at showing brief bright highlights , 120 fps motion interpolation ( except the 49 inches which use the 60 hz panel )

For its price , its hard to find major flaws on this TV

the 2018 QLED brothers :

Samsung Q6FN
Entry level QLED , comparable with NU8000, except it has better coverage of colors because of the Quantum Dot panel and thus , excellent color volumes as well ( can show wider range of colors across different levels of brightness) just like all of its bigger brothers.

Samsung Q7FN
This little bad ass is quite a buy if you can afford it . An upgrade in almost everything from Q6FN . Especially with that 2000 Nits  brightness .

Samsung Q8C
Samsung MY 's 2018  "new" model . I think the 55 inches have dropped below 10k now  . This model was actually released last year (2017) in US / UK . I  don't know why Samsung MY is rebranding it as a new 2018 TV , but their PR wouldn't tell us much . Unlike its other 2018 Q8FN counterpart , this TV doesn't has Full Array Local Dimming.
Something worth noting , these Samsung models supports Variable Refresh Rates , a.k.a FreeSync , which is nice if you plan to play PC games and Xbox games on these TVs.

Sony XF83
a relatively new Sony mid range VA model for 2018 . I don't know very much about it yet , but I know it is an android TV , doesn't has a local dimming system , has WCG, great motion features like most Sony TVs , probably the same brightness rating as last year's x8000e/x8500e , which is not impressive .

There's another notable mention , the Panasonic FX750K , which is another great VA TV. Sadly it isn't available in 65 inches .

LG 's 2018 models of the same range are all IPS panels .

Just buy HDMI 2.1 avr can dy

Just buy HDMI 2.1 avr can dy

You know this or next year got HDMI 2.1. so buying now is wrong timing

I have had similar issues with Samsung TVs before , PS4 struggling to output at YUV444 with handshake problems.
PS4 pro downgrade the Full RGB HDR to YUV 422 HDR, still having the HDMI handshake problems even after a cable exchange.

MY 3 LG TV seems to do fine with it . My friend's Samsung Q8c don't seem to have the problems , so yea I am not sure if its due to bandwidth limits or TV defective ports . There is a very length discussion thread on Sony's forum which makes me believe my problem isn't an isolated case . Outputting YUV422 shouldn't require HDMI 2.1 either.
If your TV watching habits are not too extreme , do consider an OLED . You should be safe from the Burn In risks as long as you take care of the TV.
No other TVs can come close to the picture quality of OLEDs

LG OLEDs from 2018 does come with a new logo dimming features in additional to Picture Shifting and Pixel Refresher  .

It turns down the brightness of static logos by roughly 20%. This will probably slightly reduce the chance of getting BI , still the 20% is nothing much since these 2018 panels are quite damn bright.
LG and some retailers also provide warranty for "burn marks" ( according to them ) for the first few years , so you shouldn't need to worry too much about burn in issues , at least not for the first few years within the warranty period.

With that being said , if your family watch channels with static logos , that can problematic in the long term .

I won't say it is competely safe , everything come with a risk . It is whether if the Picture Quality offered by OLED worth trading the risk of getting BI  . For me and many of the OLED owners around here  , it is worth every penny I have spent on it , so much that I am a proud owner of 3 OLEDs right now
The important thing here is to understand why is the screen is vulnerable to BI , because of the uneven aging of the OLED pixels .
Static logos tend to be bright , colorful . The brightest candle also burn out the fastest , the same logic applies here.

So the key to avoid Burn Ins ,  is to vary the purpose you used TV for . Playing games for awhile , watching sport channels of 2 hours , use it as display gallery for 30 minutes , back to watching HDR shows on Netflix etc etc
There also a massive flaw on these OLED TVs .  Once you get used to owning one , you will not want to go to cinema , because you will keep staring at the black portion of the Cinema screen and wondering , why does her hair looks like gray

what about LG 65 UK7500 vs Sony 65 X7500f?

Is Panasonic 65FX600K model good ? Aeon now selling at RM3699.

My budget range around 4K, any better recommendation ? Noob at TV updates.

Thanks.

No worries, i decided to increase my budget, lets say around 5-6K.

What model should i look for if i unable to find the 65NU8000 ?

Thanks.

Something to consider: It's an IPS panel. Its native contrast ratio won't be as good as the Samsung's VA panel. In a dark room, black will appear like dark grey. Lighter than what a Samsung VA panel would be.

Another thing to consider would be the brightness and panel refresh rate. For good HDR, you need to go for a panel that is capable of more than 600 nits on top of having wide colour gamut. a 120Hz native refresh rate would be also ideal if you're into watching fast-moving sport scenes like football. It helps smooth out the picture a bit.

The Samsung NU8000 ticks all these boxes.

i see.. becos now i actually watch movie 42inch also okay-ish.. 65inch kinda overkill for bedroom    plus 1.5m if 65inch, really too big to play ps4 with it. oled can only afford 55inch..

Based on This chart I got to go 85 inches for 12 feet le. For 4k tv

For the calibration we need professional calibrator ? Can we do manual calibration ourself based on screen instruction or eyeball calibration ?
