Technically it doesn't need full HDMI 2.1 as that is for 12 Bit Panels I believe and 8K but not fully sure on that one. I would hope it can fully utilise full VRR still though as HDMI 2.0 can't

Was set on a CX now I’m wondering if I should go C9 !
Same 😒,. Though surely the CX can't be a downgrade surely? As the LG representative stated, they used the resources elsewhere for better optimization or something in the lines of that?

yeah makes me more undecided now though.

Anyone know if peter Tyson are good for ordering TVs from or Richer Sounds, unsure which one offers best after care support?

I got a 65 inch GZ950 from Richer sounds and after 6 weeks it developer a fault a vertical line of dead pixels. Got on the phone to them the guy asked me to take a picture emailed it to them and 5 minutes later he phoned back said he'd send a new tv out straight away and take the faulty one back with no problems.

Could Steve or someone please clarify what this even means? Does it mean that the 2020 range is better optimised? Or that they have 'downgraded' the port in some way and what does this mean for the future?
I'm not sure to be honest. As others have pointed out, you certainly don't need 48Gbps for anything other than 8K and maybe 12-bit. So from a practical perspective it won't make any difference. LG's rationale sounds strange, seems more like a cost-cutting measure to me. All I can say is that along with the lack of UK TV catch-up services, it definitely makes more sense to buy a 9 Series instead at the moment (as I said in the review).

Its a strange decision, but from what Johns articles says, 8K panels are at least covered with 2 full fat while the 4K panels wont require full bandwidth, so only issue is 12bit sources, but as the panel is only 10 bit anyway, will it make a difference??
You have to assume (and we all know we shouldn't) LG have tested this and know what they are doing. Its a shame they didn't reveal this at launch as now it looks suspicious, people may interpret this as the X series is not real hdmi2.1 (although factually correct), when it will actually work with all devices coming out soon.

While I look forward to the next gen console launch, I really hope the 9 series > will not have any issues with the hdmi2.1 consoles.

Edit, I see Samsung have done the same on their Q80T - hdmi 4 is limited like the LG’s, 4K 120Hz 10 bit 4:4:4 according to Vincent, so maybe all manufacturers will do the same going forward ..

How do companies like LG get away with such daylight smudggery !

More reason to get a Samsung this year me thinks! ;)

Maybe the 9 series was just a little ahead of its time...

The 9's had a more, custom solution. Presumably that was expensive and unnecessary for 4k, 10bit panels with an upto 120hz.
I'd guess they have switched to externally available chipsets now.

I was always a little sceptical about what the 9's solution might actually mean for certain content types later on down the line. Hopefully this is the end of the story.

I'll be really suprised if the Q800T /Q900ts or Q950ts didnt have full HDMI 2.1 . Samsung in their defence are on record of saying the HDMI 2.1 features will be distributed across the 2020 range with the higher up models having the full HDMI 2.1 whack .
LG just flat put lied ! Tell you people , it's time to jump ship ! OLED peaked in 2019 ... it's the year of the Qled

Will you be doing a recommended picture settings guide for the GX/CX in the near future at all?

Jump ship to Samsung...maybe when QDOled arrives but not before ...

No, but just select Filmmaker Mode and you're good to go.

120Hz BFI ist big difference to last years 60Hz BFI and a game changer for SDR, sports and gaming:

Motion on OLED is now better than on LCD. Now we have superfast response time and usable BFI.

Thread about BFI performance on the 2020 OLEDs in the german hifi-forum.de:


SaH on OLED like the C9 compared to CRT:

BFI CX in 2020



It´s a shame that only few reviewers testing BFI. Good scene for testing is
"Casino Royale" (Blu-ray) 05:30 - 05:45.

Make good BFI tests and you will see, it will matters, especially for users those are sensitive to sample-and-hold motion blur!
Also if you watch SDR with reduced OLED light settings, there is no brightness drop with BFI up to "middle" if you are in the brightness limit which the OLED light setting allows on the varied BFI settings. 15% for low (270 nits calibrated), and 40% for medium (180 nits calibrated). For example, if you watch SDR with OLED light at 40-60 you don´t see a brightness hit with activated BFI (low/middle) compared without BFI. There are many OLED users out there, they even watching in daytime with an reduced OLED light setting.

TV manufacturer starting the 8K race and without BFI and more than 120Hz fps, it will be a sample-and-hold blur mess. MCFI at 8K and 120fps will be an artefact soap opera mess and it´s still not enough to avoid sample-and-hold on an 8K panel. There are many reports on native 8K on Samsung/LG TVs irritated by higher motion blur compared to 4K panels and worsed MCFI with more artefacts.
Better motion will be much more important than better brightness in the upcoming years with bigger screens and higher resolution.


If you don´t testing BFI detailed (240fps-960fps video, brightness drop and compensation at difference refresh rates and settings, rolling scan frequency etc., UFT test), you never will notice BFI differences from manufacture to manufacture and your review will be less meaningfull for many readers.
Do you know that the auto-mode is not available in the calibrated expert mode (SDR)? Will it be the same for Sony AH8 and Panasonic HZW series and will there be differences in the rolling scan frequency? Without valid test procedures for BFI against motion blur at different settings you never will notice.

Yup. This is the killer feature for the CX. Near perfect motion in SDR is VERY hard to pass up IMO.

Of course for HDR, its kind of useless because we need every nit we can get but it makes SDR god-tier mode in regards to motion compared to every other modern TV on the market.

Yeah that’s my personal YouTube which is full of random experiments and nonsense.
Wow. Good to see you here. Perhaps you should start your own HDR thread here :)
