      Great review, thanks. I can confirm the 3D issues you had with the EF950 were indeed correctable and probably as you say misaligned filter. 3D on my EF950 is stupid good and no doubt similar on this TV.

      Passive 3D OLED is definate bonus on these TV's, possible being one of the last great 3D TV's, 3D lovers should clamber to get one of these if they like curves or the E6 if they dont.

      However, with 3D being so dawn good its hard to believe that LG will drop this feature even if every one else does, 3D movies are still being made and could still come out on bluray.

      3D does have an uncertain future though but i'm hoping 3D OLED will renew peoples interest in it as it's just mind blowing with a good 3D print.

      Thanks for the review, any plans to do one of the 65 c6, and I hear Lg are aware of the problems with HDR10, do you think that can be done via a firmware update.

      Yeah I can also confirm that 3D looks amazing on the EF950. I've never enjoyed 3D... until I got my EF950.

      After using the Panasonic UB900 with a Samsung JS9500 I've now changed my set to an LG 65C6.

      Since before I had turned off deep colour on the player as it could introduce macro blocking, but I'm unable to turn it off on the TV - if I do I will unable HDR playback and the player and TV resorts to SDR. As an experiment I tried to turn on deep colour on the player taking a chance the TV would handle it. The best scene to try this out is the dust cloud in the beginning of Sicario when the bomb goes off.

      In short, the macro blocking is still there, and the problem is that turning it off but leaving it on on the TV does also show almost the same amount of macro blocking. So it's almost same same if I enable it in the player and TV. When I used the Samsung JS9500 the main theory was that the material on the disc is 10bit and the Panasonic output 12bit and the conversion causes the macro blocking in some cases (most notable in Sicario and some of the sky in Mad Max fury road).

      That said, the macro blocking on the LG is far less disturbing than it was on the Samsung (it's OLED after all? ;)) but it's still there.

      Any one more experienced owner of the LG and Panasonic who knows the best settings or a work around? Do I need to have deep colour enabled on the LG for it to receive and handle HDR material?

      Yes you do need to turn on the Ultra HD Deep Colour setting in the LG's General menu but I would just leave the Deep Colour Output setting on the UB900 to Auto. See how that looks.

      I think the colour tracking against Rec.2020 could be fixed with a firmware update; as for the clipping I don't know but the fact it doesn't clip with Dolby Vision suggests that LG should be able to address this issue with a firmware update as well.

      As far as the 65C6 is concerned, I think we'd rather get a look at the B6, E6 and G6 first.

      When you post a review of something like this I always imagine your finger hovering over the enter key thinking "nah I'll just enjoy this silence a little longer"...
      Then brace yourself "Ok here goes" :laugh::laugh:

      Thanks for the review :)

      We'll review the B6 as soon as possible but we're dependent on getting samples from LG, so it depends on how quickly they get them out. They've been particularly slow this year.

      I wonder why less choice of curved tvs this year, if i was to consider a new tv this year either the 55" or 65" C6V would be top of my list.

      Thanks for the review, great work. I have a few question more about the testing than anything else

      I would fail to understand peak nits is tested @10k nits. Is this in anyway valid, would not a 4K nits make more sense and I understand the colour space workflow is based on 4K nit. So 10k nit test is mostly noise.

      Assumption the LG and Samsung track to PC3 rather than BT2020 because they feel the result are butter?

      The HDR specifications for Ultra HD Blu-ray go up to 10,000nits and use Rec.2020 as a container, so although a TV may only have a peak brightness of 1,000nits or less, it should still be able to effectively map a 10,000 nits signal to the limitations of its display without clipping. The same goes for the colour gamut, although the original content is DCI-P3 and the TV has a native gamut that is close to DCI-P3, that isn't a domestic colour space. All the Ultra HD content is using Rec.2020, so the DCI-P3 content is encoded within the Rec.2020 container using Rec.2020 saturation points. Therefore the TV should track those Rec.2020 saturation points up to the limitations of its own native colour space. So as I understand it, the approach taken by Panasonic and Sony is correct but the current tracking on Samsung and LG TVs is wrong and will result in saturation and hue errors with content encoded using Rec.2020. Which is why we have reported this back to both manufacturers and they are currently looking at firmware updates.

      Well over a grand for a TV (nearly 3k for this one) may be affordable for some of you but not the the majority of people. Hell, even a 1080p OLED will set you back a fortune.

      Yes, I did test that. I had deep colour on automatic on the UB900 and tried the beginning sequence of Sicario, first in the van when light beam shines in over Emily Blunts shoulder and secondly when the bomb goes off and there's a dust cloud behind Emily Blunt and around one of her wounded colleagues on the ground.

      Unfortunately the macro blocking is still there, I think the problems are almost equally annoying if the UB900 has it off or automatic. Could be slightly more troublesome when on auto.

      is there any reason LG can't make one a bit smaller...??...a 48" / 50" would be perfect but the 55" and above are just too big.....i would get 1 tomorrow if they did a 50"

      Steve, I get the impression that on the whole you preferred the HDR picture on the ks9500 but the non HDR one on this set-- is that accurate.

      Getting the most out of the 2016 OLEDs HDR wise seems to be heavily dependent on how much Dolby Vision content there is eventually -- so it might be worth hanging in until it's clear whether the PS4 neo has DV or not? (Which strikes me as the key factor as to whether DV has a real future in physical media)

      Regardless many thanks for this review --has given me much food for thought (as well as taking this from a day 1 post price drop purchase to a more wait and see approach...)

      Hi Steve thanks again for the review.
      One question, given the OLEDs blacks and infinite contrast etc. and your comments in the review how come the C didn't rate a 10 rather than a 9 in the 'Contrast/Dynamic Range/Black Level' score bar?

      Well the fact that blacks were crushed on occasion and the C6 clipped highlights in HDR pulled its score down to a 9.

      Excellent and honest review.
      I think we might have to wait few more years before OLED can reach 1000 nits to enjoy HDR content as it was intended. OLEDs are getting brighter each year, so by 2018 LG might hit a thousand nits and eliminate other niggles like crushed blacks. The fact that OLED can't go bright as high end LCDs, to enjoy HDR 10 in its full glory, is its Achilles's heel.

      I don't think you can actually turn off Deep Colour on the LG, well you can, but on the B6 certainly, as soon as it detects a HDR signal it forces you to turn the TV off and on again and kicks in.

      @Steve Withers , were there any particular objective reasons for choosing HDR Standard over HDR Bright (I can understand things from the Dolby Vision perspective)?

      I found I quite like HDR Bright, although you have to actually drop the brightness control a few clicks to set black level correctly (not sure if this will vary content to content), it seems to give an increased overall dynamic range.

      Did you happen to measure the greyscale and gamma in the HDR Bright mode as a comparison out of interest?

      Thanks

      hey guys just a heads up the E6 is way brighter than the c6. E6 can get over 700 nits

      From John Archer review of the E6 from Forbes magazine
      "LG has been at pains to state that all of its OLED TVs for 2016 should perform pretty much identically. However, it quickly becomes apparent that the OLED65E6 is in fact quite a different picture quality beast to the previously tested OLED55C6.

      The biggest difference is that the OLED65E6’s pictures look significantly brighter than those of the C6 – something which has the potential to prove very handy with high dynamic range content.

      This brightness difference isn’t just some kind of illusion caused by, say, the glass-based design, either. The OLED65E6 measures a peak brightness of over 700 nits if you use its High Dynamic Range Bright setting, an increase of nearly 10% over the C6."
