Added a link to this recent comment from jjref comparing C8 motion performance to Sony's: https://www.avsforum.com/forum/40-ole...l#post55946904

Seems LG still has a noticable gap to close...

Also quite a few 4k TVs support native 120Hz input at 1080p, and some even support it at 1440p.

It's very rare to find TV's that support 4K 120Hz 4:2:0 8Bit. Most TV SOC's simply don't allow it. It's not a matter of just meeting the bandwidth limits of HDMI 2.0 but also insuring the TV SOC has support for it without locking the user out completely.

As for 120Hz 1080p and some (rare) 1440p numbers I've seen they all go over 8.33ms. There is still room for improvement!

Now if people are happy with 120Hz 1080p on their sets that's fine, but I want full fat 4K 120Hz 10Bit native inputs with support for VRR which HDMI 2.1 will allow along with the new SOC's Mediatek and other vendors are working on for mass rollout in high end sets next year.

Some of these features like VRR, etc can be implemented in current HDMI spec the new Samsung is rolling it out, however I sadly doubt most other manufacturers will enable it in a future firmware update...I hope so though since Manufacturers should do everything in their power to deliver the best exp to the buyer and after purchase support. An area I can point to where many owners have felt let down in the past.

I'm hoping a lot of these "hopes and dreams" become reality next year, but being in the high end display game for so long I know it might take a few more years before we even see everything I'm requesting. Progress is slow till one day it meets your needs and you move on to something else to attain.

I suspect there are many EF9500 and C6P owners like me, eager to upgrade to 'fully-baked' HDR but not feeling any urgency.

This is not an open-ended 'which year will be the best year to buy' thread but a focused discussion of C8P deficiencies that may be addresed by the C9P and whether those hoped-for improvements justify holding off until CES 2019 before making a decision.

I could obviously held off on starting this thread until more reviews and early-owner feedback on the C8P are available but since my preliminary thoughts were already clear based on what I've seen from jjref and imagic over the past week and since the thread can always be revived later if it slips into the ether due to being premature, I decided to go ahead and get it started now...

Would welcome any constructive input you may have but if you feel that is waste of time this 'early' in the 2018 cycle, NP...
Well if you want to buy in November of this year, then you won't have a clue what the C9P will be like since it won't be shown until CES in January, and even then details are likely to be missing until March.

Separate anti-banding/posterization (smooth gradation) and noise reduction options (currently it's combined into MPEG noise reduction, which some don't like).

If it turns out to be a problem, try to eliminate noise/whine/buzz from TV in some situations.

Produce panels in such a way that there isn't a calibration square burnt into some of them.

Get some of Samsung's magic anti-reflection material.

An ATSC 3.0 compliant tuner so the TV can receive over the air (OTA) broadcasting of 4k signals. Since Korea is the first country to actively broadcast 4k signals using the ATSC 3.0 standard, this shouldn't be a problem.

And, it's a requirement for any new TV I buy. So no new TV for me this year. But maybe a c9, yes LG?

Ooh, and hardware AV1 decoding... which probably won't be ready until 2020 models, unfortunately.

When I first saw the thread title, I thought.... this has to be an April Fools joke. Sadly it wasn't.

Early C8 owners have discovered that BFI improves near-black uniformity (but at the cost of some visible flicker).

A 240Hz panel offers a few benefits in the area of motion-performance, but it is now clear that it could also deliver improved near-black uniformity without flicker.

Since improved near-black uniformity seems to be rhe most important feature for those WOLED owners mulling an upgrade to C8 versus a 2019 WOLED, I updated the lead post and used the second post to explain how BFI improves near-black uniformity of WOLED and hw a 240Hz refresh would allow that improvement to be delivered without introducing visible flicker: https://www.avsforum.com/forum/40-ole...l#post55943228

Typing up that last post made me think of an interesting question:

For those EF9500 & B/C/E6P owners mulling an upgrade to a 77C8P or C9P, if the C9P only comes in 75" but delivers significantly-improved near-black uniformity, would you give up 2" of diagonal to get that improvement in near-black uniformity or would you want to jump on the 77C8 while 77" WOLEDs are still available?
