Thank you
They did not implement dither. Their BFI implementation is what cleans up the low end.

I thought some might find this to be an interesting observation from John as we continue to compare these displays. Did cause a slight pause for me on my Sony decision as I prefer and enjoy the most accurate picture possible... although I understand the differences post calibration between the 2 displays may be negligible.
And just an FYI, I do all of my evaluations without the external LUT unless the panel in question is the reference during the evaluation. Having said that, I still prefer the A8H over the the CX due to the CX less refined upscaling of low bitrate/resolution content, BFI implementation, how it handles DoVi per real content (the CX measures different between DoVi Low Latency (i.e. Player-Led) and Profile 4 (i.e. TV-Led) and elevated blacks with HDR and DoVi. IMO, being able to load an internal LUT compared to external does not trump these items.
Ok so this info is very helpful and definitely provides some better perspective. Thank you. You’ll have a pm coming your way shortly as I would like to arrange a visit to your place to see how both these displays perform with my own eyes. 🙂

Which is why both sets have plus's and minus's and depending on what's important will make the decision.

Also, i know we need to see it implemented, but LG has committed to fix the raised black issue with HDR and DV on the CX.

So in absence of dither we can conclude that the potential (but rare) problem with chrominance overshoot or flashing is still present in the A8H and in this specific aspect LG is still superior or better than Sony? Thanks

As I said last night, I have yet to see it in content that has shown it in the past. If you have specific content you would like to me try, please post them.

Watched the mini shootout,the A8H is on order. I think the differences were enough to go with the Sony even with the $300.00 difference.

I'm leaning towards the A8H and I'm still leaning towards the A8H after the comparison. The LG may make up the difference with rendering low bit rate content if AI is enabled but BFI is better (hardly any brightness penalty) on the Sony.

It would have been interesting to see how a Samsung 900T would have fared.

right I'm still kind of eyeing a new TV for my living room next year. IIRC last year the A9G had the dv bright and dv dark picture modes but the A8G did not, wondering if thats the case with the A8H this year

Yea i think the a8h has both dolby bright and dark the only thing holding me back is the 2.1 aspect for the new consoles I game in my living room and bedroom

When you watch a YouTube video on a LCD monitor, you're not going to get the real, no pun intended, picture. I saw some positives and negatives on both, but I'd never base my buying decision on those videos. I hope John posts his thoughts.

I watched on my OLED and I wasn't able to discern much from the video. You really need to rely on the comments from the participants who were there. John did post some brief comments in the CX/GX thread.

I'm getting tempted. If the flatpanelshd review verifies that Sony has adjusted their dimming algorithm so brightness is not greatly reduced during gaming after a static image is detected I will probably end up buying one. I need that confirmation along with Rtings sustained HDR numbers showing Sony is back to pre Dolby Vision update Sony A1E nit numbers or better.

Honestly until Samsung does a major change, it's pointless to have them there. The OLEDs will beat it up like Jordan hearing a someone talk trash to them yet again. The Samsung is always the Scott Burrell of every shoot out.

If you have read all of the post in this thread d-nice has it pretty much summed up. John made a call to him during the shootout and both of them shared great info both sets.

GREAT job, John. Take care of that cough there. You have some of us worried !

The one comparison test that I wish you had run (and it's my chronic #1 question) would have been some typical, average, 1080i broadcast material, to compare head-to-head upscaling. There was a little of that golf tee/driving off tee by maybe Tiger ? Could not tell much from that.
But bottom line, I feel as if YOU did actually address that by saying (paraphrasing) that though gap is definitely closing, the A8H still holds a bit of an edge (better) there. So it's all good for me.
Many thanks John, and to a nifty contribution by D-Nice, who had so much experience to lend.

@jrref @D-Nice Just watched the whole thing and that was a really great breakdown. The way the Sony extrapolates HDR from the SDR calibration is something that has always interested me, since I don't have the option of an HDR calibration, but I do have tier 2 calibrator that can do SDR where I live, just wish Sony would take more interest in gaming on their displays, but I know that's not the case unless something changed very recently based on what D-Nice has said.

Something I noticed when discussing the differences on the star field, I think the CX had dynamic tone mapping on as it was turned off at some point after that demo. That might be worth a re-check.

Just watched the comparison video. D-Nice could you clarify the BFI max settings on both the LG and Sony? You mentioned the LG operates at 60hz and the Sony at 48hz. But I'm assuming that's only when feeding both of them 24p sources, and both would operate at 60hz otherwise? Because prior Sony OLEDs BFI operate 60hz and then switch to 48hz with movie content.

Also some other questions:
1) Are the max BFI settings for both LG and Sony essentially the same BFI settings in their prior models just carried over to this year? It seems like they behave the same way and that there is no reason to ever use them over the two "lower" settings, unless I missed something.
2) On the Sony, is there any scenario where you would not use Clearness 2, given there is no brightness loss or uncomfortable flickering? Would you use it for HDR and DV?
3) When using the Auto mode on LG and the Clearness 2 on Sony with movie content, is there any advantage to Sony's 96hz playback vs LG's 120hz playback or do they both look the same?

Thank you again for all of the in depth technical details. Looking forward to the Kuro comparisons.

This is something I would have liked to see as well.

Watched the comparison twice, at least the motion blurring section, with all the changes that happened during that part of the test, I still am not sure what we were watching when and which one was best.

Time to find a BB that has both and go take a look for myself.

@jrref also.

D-Nice,
watched the comparison video. Some interesting points. Regarding player led and TV led, do you have some examples that are fixed player led and TV led for the LG, in 4K players and/or streaming boxes? This could impact your choice of player and/or TV.

Regarding BFI on the LG at max, I think you said that you could like that setting as being plasma like, but it would need a new calibration because of large brightness reduction and PQ/EOTF change. Would a special calibrated setting for that work for each SDR and HDR (from disc)? I assume in this case you would still have some motion artifacts because interpolation can't be completely disabled with BFI on the LG?

So one question I have before I go ahead and order one of these TVs is that someone mentioned in another thread that the CX is "more accurate" post calibration than the Sony. What exactly does that mean? Obviously we were all watching via YouTube so we're dealing with the same source but that didn't seem to be the consensus of the people in the room (or maybe it was just Robert). @D-Nice said that after calibration, he could still see the difference (although it's very, very close) and the Sony tracks better than the LG.

Too much sameness for me as a a9g owner. It looks they havent implemented any solution like lg and panasonic did to tackle the low end chrominance overshoot and the resultant flashing and other artifacts. It appears to be a a9g with an updated bfi feature . I want something different for my second oled tv, not feel like im using the a9g with a different aesthetic. I'll be back to check out the lg cx and panasonic hz1000, need a comparison video between these two tv's (hopefully vincent does a cx vs hz1000 comparison soon as he has procured both the tv's now). I have the a9g in a dedicated dark room, but since the second oled would be going in a bedroom that is not a dark light controlled room and gets some natural light, the higher brightness /average picture level of the lg or panasonic might also come handy.
