seriously, i've had this discussion too many times over the 3 years i've had my panel, I have no issues that arent on the source, and i'm not prepared to waste any more time looking for issues that just arent there. Maybe i've been lucky and you've been unlucky with your panels, really sorry if this is the case but I have two other mates with B7's and they also reported zero issues. if the panel is so bad why dont you exchange it?

I don't recognize these problems , but I will check if Home Theater would be an improvement... |

The gamma value set in "this display is already calibrated" (I'm guessing it is the default 2.20) might also be crushing black. I would experiment with that after changing the brightness of the display. I've gotten the best results with gamma 2.40. You could also try the other way and use gamma 2.00. If you set the target nits to 480 nits, you get a neutral reference white (100 nits) without compression. This would mean your display would have to be 480 nits or so to avoid the most unwanted compression. Basically, make your SDR calibration brighter so HDR content has room to breathe.

Panasonic no longer sells panels in the US. I would have bought one in a heartbeat as I love my Panny plasma. Sony until recently had some issues that were finally fixed in firmware updates. And finally, I got my C8 for a price that can't be beat. That's the short answer in my case.

The only working PQ pre-tone mapping feature that I know of uses presets of 500 nits, 1,000 nits and 1,500 nits. An OLED is supposed to select 1,000 nits. If it is actually 700-800 nits, the pre-tone mapping is just reducing the brightness of the input for about 20% of the HDR titles out there. So it isn't really that useful unless your display clips at the top rather than tone maps. All the new OLEDs also use dynamic tone mapping and shouldn't need help from madVR unless HDR -> SDR is used.

Also I didn't know anything about this problem when I bought the LG because usually all you read on forums is "it's a source problem". |

if you read the reviews on OLEDs there is very little difference in PQ across all ranges as they are all the same panel tech, differences are mainly motion related.

In any case I am starting to think that the problem is that the GTX 970 does not support HEVC 10-bit. LAV works is software and I guess it is somehow reducing the quality of the image to handle the workload. |

I think you'll just have to experiment with settings to get the best quality picture on your particular TV at the distance you're watching at, and accept the fact that certain sources don't lend themselves to a lot of improvement. |

Yeah.You're exactly correct.In general if one has a TV set with HDR at hand,that person doesn't want likely to do such the conversion of HDR to SDR.Because such the conversion will make HDR existence meaningless unless that persion has just an earlier SDR TV set at hand.Anyway I think the algorithm 'process HDR by using pixel shader math' is very very important in madVR because the algorithm may be the most powerful weapon that madVR will improve HDR image quality in the future

there is more than one example with the exact same frame where the LG utterly failed. |

As a % of people that watch movies, whether bluray, 4k discs, streaming, cable or torrents, how many do we think use MadVR 1%? Surely less than 1% lol I also find it funny as Mclingo is/was very active on AVforums and everytime a new LG OLED TV is released that forum cries out for "SLIDES SLIDES" louder than a deprived smack addict, all so they can evaluate whether the near black performance is improved on last years |

Anyone try 411.70 yet to see if the HDR issues have been resolved? I'm downloading it now.
EDIT: Nope....still a broken mess for HDR. How nice. Back to 399 I go.

firstly - as I stated very clearly I use MADVR to resolve macro blocking souce problems, not to correct inherent problems with my TV. Secondly - slides requests on AVFORUMS were for the evaluation of near black banding bars around 5%, this is still common on all OLEDs and something lots of people are interested in as this shows people the progress LG are making on all panels to improve this. Anyone who has an OLED or is intending to invest in one should care about this because its OLEDs main problem, if you want to know you've got a good panel you have to look at your 5% black slide, rock science this isnt. These near black bars have nothing whatsoever to do with the near black macroblocking issues which were being discussed, no idea why you felt the need to bring any of that up.

famasfilms could you avoid quoting entire posts that large please? You can edit them down to particular sentences. You quoted about five times more than what you wrote.

If the TV is not smart enough, it will simply apply a compression curve to every pixel. If madVR has already applied tone mapping before, that means the TV will compress the content even further. It might not be a dramatic problem, but it's far from optimal. Quote:

Probably I should rename the options in madVR, because they seem to be confusing for users. People seem to think that HDR TVs can somehow do magic, and letting madVR convert HDR to SDR will produce worse results than if the HDR TV receives the full HDR content. In reality the HDR TV will do the same processing madVR does - only in worse quality. Not true. See my reply to Razoola. |
