    This is a B6 post-calibration (20pt). This was found on another forum (avsforum).







    Btw, there is one people who pre ordered a Barco Thor on this forum, and there is a entire section devoted to ultra high end gear when people discuss about their 20k+$ gear minimum. For reference, Thor is a 6p laser home theater projector costing about what...400K$.

Also, apparently in HDR mode the brightness goes down to around 700 nits after only about 500 hours. Said that, Panasonic uses the very same screen on their professional unit 65CZ950, but it cost around $11K. They spent a lot of time working on the black artifact issue and it is much better, than standard LG TV. Apparently there is an even newer Panasonic model now, but it just came out and there is not that much info on it. I suspect in about a year, you may be able to finally buy a proper OLED Panasonic monitor suitable for grading, hopefully for around $5K.


    I think you speak about the 2015 LG OLEDs, not the 2016 LG OLEDs, but I coud be wrong. Moreover, lifetime is greatly improved from the 2015 sets, becoming a non-issue (dunno about brightness btw, never heard that !). I've seen a lot of tests on the new LGs, and on very specialised website with very deep test and they all conclude they are pretty awesome.

    6pt report means very little... Especially with these screens that exude nasty behavior.... Need to see at least 1000+ val points but even then, if it looked good in the report, u could have nasty side effects that the report will never show...

    Blue is bad... But more importantly red is too high... Since this is primaries/secondaries only we know nothing about actual real world performance since barely any footage contains 100 stimuli...

    Which particular artifact? The 2015 LG OLEDs had, what people have described as a vignetting problem near black. Put up a low (5%) gray image and you saw this vignetting type of artifact. This has been corrected in the 2016. Another issue was crushing black. Everything below some % (5-10 I think) was simply gone. This should also be fixed in the 2016. Or at least improved.

    LG disables all of the calibration controls in HDR mode, which is a problem. They are in fact enabled if you launch the Amazon app. The problem here is that every time you launch the app, it sets the controls back to a fixed value.

    I don't recall the exact number, since I am visiting family, but 700 nits is about all the 2016 can do using a 10% area based window. So, it does not drop to 700 nits after 500 hours, it is already there. :)

    There is a particular edge lit LCD that has a UHDA Premium logo. It drops from 1500 nits to 500 nits after so many seconds. It never even comes close to 1000 nits with real content.

    When we hear about nit values, it is usually only on a 10% area sized window. e.g. The Sony BVM X300 does ~1000 nits on 10% area. Full screen is closer to 177 nits. OLED can also light up a single pixel to that brightness level. This is why a starfield on an OLED looks so amazing and three dimensional.

    Politics? CE industry and standards groups around it are so political. What has been interesting with the early UHD sets is that usually only one input on the display supports HDMI 2.n. Not sure if it was because of a shortage of parts or cost. One CE company recently mentioned they don't usually put that on input 1 because that is where many people plug their cable box into.

    Seems sort of bizarre think not to have - especially if the manufacturer wanted to give their device the start-of-the-art look.

    Edit : Hmm. I think it might be just my perception? Maybe 'wires' is the 2016 thing? ;-)

    As of now I don't have it calibrated. I Just hooked it up to the trashcan HDMI, which I hacked the bios on so it does 10bit 25p UHD. There is a rec709 and rec2020 profile for the LG screen and this week I will try to see how well I can calibrate it with my i1display probe. simply run i1display ontop of those profiles and create and adjustment profile and then compound them to get a, in OSx profile that is actually calibrated.

    But I also ordered these which will come in a week or so.
    the 12bit Ultrastudio 4k: https://www.blackmagicdesign.com/pro...diothunderbolt
    and the 12G sdi to HDMI lutbox from teranex https://www.blackmagicdesign.com/products/teranexmini

    That according to the guys at BM will give me a good calibrated 12bit signal all the way to the processor of the screen.

    Regarding the artifacts in the blacks. I think that was 2015 LG screens. The screens that came out late this summer should be different. But I can see errors in the blacks in a pitch black room if I bring up the "oled lights" setting to the max. But at a 50 out of 100 setting then the screen is freaky black in the black. I'm not joking it's like turned of black, and when looking at a gradient there where no clipping into that black.

    As I understand these LG's do 700nits. it's not much in comparison, but as I see it it's a lot considering their deep blacks.

    Possibly there are better screens, more accurate, higher nits etc. But for me this beats all that I seen before. 65" and UHD is a good combo as I see it. I have the screen about 1.7m away from my face above my cinema display and to me no 2k or HD screen can compare, especially in that size. I will hate to do HD work from now on, as in comparision it really feels like 320x280 or such.

    Now LG will announce next years screens very soon and my guess is even greater range, more accuracy etc. As all the bullshit sales things like curved, not curved, 3D etc is all played out already. So the next trend I think will be different certificates for color accuracy, range and so on. Which is already started to happen with UHD Premium, Dolby Vision and so on.

    They get you with the fries! No, wait, that is fast food. They get you with the cables! The markup on cables is crazy in the CE industry. Monster Cable was a license to print money. I did get to drive a number of exotic cars thanks to Monster Cable though. :) My theater is wired with Belden 1694A and Canare connectors. I think I bought a 500' spool from B&H very cheap.

    Yes, crashing of the black is the main issue I was referring to. Using that type of monitor for critical, color grading is still not an option and, for obvious reasons, there is no calibration, that can address it:)
    As I said, Panasonic greatly improved handling of blacks, but at $11k it's not really that inexpensive. As far as LG itself improving it? Well, I'm sure it's been addressed, but the question is how much improvement there really. I don't know. I hope it's finally good enough.
    Let us know:)

    Its not crashing the blacks. and with a 12bit lut box why would it not calibrate?
