There are no new OLED TVs at that price , the best you can find is Panasonic's two years old 55" FZ950K on Lazada 's Chup Dulu for RM4999.

Which one would you choose?

65" Samsung RU8000 or 55" Samsung Q80T?

Both have same price now.

Should i go for Q80T and sacrifice on the size?

Usage is for gaming (current PS4 and future PS5) and movies.
Comparison are as link below

Here telling you the reason - https://www.rtings.com/tv/reviews/best/by-type/oled

C9 is color accuracy out of the box. B9 you need to calibrate it.
The scores given by rtings on accuracy is 7.6 (C9) v/s 4.9 (B9)

Beside this C9 had better HDR than B9. Scores given by rtings is 7.3 (C9) v/s 6.4 (B9).

Comparison - https://www.rtings.com/tv/tools/compare/lg-...4&threshold=0.1

Most reviewer is recommended C9 over B9 except rtings, probably due to it is must cheaper and rtings is a calibrator pro.

Show room 99.99% is loaded with vivid or standard mode. You cannot use it as benchmark.

Panasonic OLED is well known freaking accurate in colour as well but in show room is as vivid as others as well because show room always on with demo mode which is maximum vivid mode.

IF you are movie purist , want to get best color accuracy out of box. Get both hdr 10 + & dolby vison format . got best quality of low-bit video streaming content playback performance,  you should chose GZ1000.  If you are heavy gamer, need hdmi 2.1 feature , better chose c9.  I won't choose Sony  a8g  because  Sony dolby vison using  low latency version  not as good as panasonic & LG which had dedicated chips for dolby vison. some more, A8G  only equip with  old  4K HDR Processor X1™ Extreme , not flagship  Processor X1™ultimate. So only HDMI ports 2 & 3 support the full bandwidth of HDMI 2.0.  Unlike the X950G and A9G.

Food for thought; get a C9 and hire a calibrator to calibrate it. It'll still be cheaper than a GZ1000 and you'll get much better color accuracy as well.

Not easy to find calibrators? 
Join the HT MY club on FB. Plenty there.

As for price, isn't it selling RM11,999 on Senheng? The C9 65" is only RM8888 at Best Denki.....

kkthen already reply you with great answer. but I think GZ1000 is some how too expensive. I still prefer C9.

touristking For your another two question.

Sound, get a decent sound system. Most TV sound is not very good even mentioned support Dolby Atmos.

HDR10+ title is very little and no any streaming platform support it.

Any Android based tv have google cast built-in

If you have specific models that you've been eyeing, guess you can chrck the spec also

I rarely do that, but if needed, you just use phone to type in, get the result, and cast to TV. For example in Youtube.

i am always on cinema or cinema home mode. Vivid mode is very eye candy to my eyes, but i felt tiring after watching it for sometimes. is like feeding u sweets until u sugar rush over rush lol.

Actually for the moment, not Android OS TV can at least received cast of YouTube and Netflix from your phone over.
This is working for my LG C9 using webOS and also Panasonic EX600K using FireFox TV OS (My Home Screen).

All Panasonic TV run Firefox TV OS (My Home Screen) except otherwise mentioned as Android TV. So far GX650K is the only android TV release by Panasonic if not wrong.

I didn't use that,  local Netflix I already can't finish watch. For me it is unnecessary.

I read most people set at router.

Use routers capable of policy-based routing to route your TV traffic over VPN while letting other users/devices connect to the Internet directly, or via another VPN.

I used that to connect my infamous Turkey Netflix account to the USA servers on my nvidia Shield while the the rest of the house connects directly to the Internet.

whats the point of these high nits videos (tech demos, test videos, etc)? yes, you can repeat watching these tech demo videos...but in reality, ppl buy good TVs to watch 4K UHD movies, 4K streaming, TV shows, etc, right

no doubt Samsung TVs looks very good..but sometimes overly vivid (which kinda...fake)

Haha its ok la, I still prefer Samsung as the TV stand is higher so i can fit a soundbar. LG one too low.
