Indeed I did mention it sometime after Black Friday last year, which was only a few months ago.

I remember you having some reservations over those "inconsistent input lag" concerns, and I could sympathize with them, but at the same time, I was confident that LG would soon remedy the issue.

I was also not put off too much by it since I knew that those issues only occurred when the TV was in HDR mode. If I noticed a problem in Halo 5 multiplayer, for example, then I could just turn HDR mode off, and the contrast and quality of the OLED would still far surpass all other TVs that I had ever used.

I'm glad to see that the updates have already rolled out and are making people even happier with their setups. =)

In this review, they confirm that the issue is completely and permanently fixed:

HDR gaming on the B6 now occurs at a consistent 28.5ms of input lag. ^_^
