Hi Steve, thanks for another helpful and informative article.
I don't know if you feel it's a non-issue or something that will be eradicated over time but I had a play around with the flat panel (non curved) LG 4k Oled in Currys yesterday and it clearly suffered from black crush compared to the other TVs alongside it that were showing the same footage.
The remote control was available so I went into the picture options and cycled through the different modes and it was the same for all. I've read that Oled has a problem displaying detail at just above black level - IRE 1-5 if memory serves - and it was very evident. It wasn't as if it was marginal, it was very clearly obscuring a significant amount of detail.
I had a look at the extra processing modes but everything was set to low (dynamic contrast etc) so wouldn't have had that much of a bearing. Brightness was 50 and contrast quite high (can't remember the exact figure) which I assume to be factory settings. I was left with the impression it is a flaw inherent to the technology atm and that trying to correct it could have a detrimental effect in that the brightness would have to be turned up to a level that would start to washout out the image overall.
It was a very significant issue on the set I viewed, to the extent that it'd stop me buying one as it stands. I can only conclude that it's as big an issue as clouding, haloing etc that are mentioned in relation to LED LCD and really ought to be included in the article in order for it to be seen to be providing an all encompassing reflection of the tech.
That's no criticism though as it's a very informative piece and I appreciate you having come up with it as it's very helpful and AVF are one of the few sites that delve into this type of thing in more detail. It's just a suggestion that, based on what I witnessed, I feel could complete the picture. (no pun intended)
You're welcome to do so mate. I'm not sure I want to though as I know the type of flame wars it can lead to.Hello Paul, perhaps you could consider cutting and pasting your post on to the LG EF950 discussion thread, either the review thread or the owners' thread (or both?)
I do want to move away from plasma due to higher power consumption, ir/sb and lower brightness levels and hope the issues affecting Oled can be eradicated.
