Also do local HD cable channels and local antenna channels look good on this TV? I am debating between Samsung QLED and LG OLED, and video processing is a concern.

Only one reason to buy the C6 and that is if you want 3D? If not buy the B7.........

The B7 has less aggressive ABL and lower input lag. Only go with the C6 if you want 3D.

Do you care about 3D? If not, then for the same price, I see no reason not to go for the B7 over the C6. Some would argue that uniformity has taken a step backwards this year, but I can't speak to that myself. Otherwise, there have been improvements in input lag, black level, ABL, and CMS controls, with the addition of two new flavors of (largely untested) HDR.

Edit: Hey, hey! Consensus!

Whatever you do don't use a gray 5% slide. There's zero point to use that slide. Watch a 4k bluray or watch some UHD content like the LG OLED demos on YouTube. If the tv looks amazing then it's a good tv. This 5% nonsense is the same as looking for clouding on an LCD.

The C7 should be a lot brighter than the plasma especially with HDR sources. It sounds like you haven't disabled the energy savings option.

Thanks for the consensus opinion confirming what I was already thinking. Was thinking the 2017 model would be the better choice, and I don't care about the curve or 3D. Now the decision comes down to LG OLED or Samsung QLED. And I think OLED is my preference coming from plasma, although the video processing on Samsung is good. But I think overall OLED may have the most natural picture, as QLED may be a bit artificial and oversaturated.

That's what I was hoping. On some prior LG plasmas and LEDs the video processing was inferior to Samsung. But since this is a top tier 4K model, then hopefully the video quality and upscaling is very good. Because most viewing will be Spectrum HD cable and local antenna channels. And we also use a TiVo Roamio in place of the cable box so that is good to hear. Now if only they still made a Tivo with dual inputs for both cable and antenna. But there are other options for that.

Correct. Dolby Vision is designed for dynamic, scene by scene metadata and so does not need active HDR from LG. I'm not certain whether active HDR is available in all inputs in game mode or
"PC Input" which reduces input latency..

It definitely requires using a mode that dramatically negatively affects input response. It is quite sluggish when in use. I've read around 88ms, but I forgot where and I have no means of objectively measuring it myself. "PC Input" while HDR 10 is engaged grays out all processing modes including dynamic contrast low for active HDR. When using any other input to play an HDR game with active HDR low, it's clear the latency is increased (HDR game mode outside of "pc input" also blocks active HDR.)

I think this is the reason many have complained that Horizon Zero Dawn seems dim on average in HDR -- because the aggressive tone mapping is in full effect since the game probably wants the display to have a high average brightness level which is not OLEDs strong suit. But with active HDR low, the difference is obvious, which is unfortunate due to the lag.

Also, it seems the latest couple of LG TV updates broke HDR 10 colors while using "PC Input."

I get the same with a anthem 1120 and a LG C7 OLED

What is the firmware version on your Antham ?
I am on the latest beta firmware (due to other problems, send by the Anthem support) but another user suggested that there were problems regarding Audio Return Channel with the latest firmware. Maybe the firmware is causing the problems?

I have very light banding on a 5% gray slide but I don't see the banding when watching tv or gaming. If I was able to see the lines during normal viewing then I would be returning the set. When I view full screen color slides I have perfect uniformity from corner to corner. The set is insane, I totally agree. The only thing I hate about this C7 is the remote control is garbage. I wish it had the same auto on pointer as my Samsung JS8500 remote. Also all the TOS you have to agree with just to use the tv has got to be one of the most annoying things I have ever encountered on a TV.

You could try using the .067 firmware on the Anthem website - it solved the problem for me

What version did Anthem send you - I have had .074 and .078 they both gave me the sound problems you have

I went from a pioneer Kuro to a Samsung edge lit to the C7 oled. I still have the other 2 Tvs and would never go edge lit again. I would grab a full array local dimming set before edge lit.

I had an array-lit Samsung 1080P TV D8000, and now I have edge-lit Samsung 4k HDR KS8000. I am never going with an edge-lit either.

I had that KS8000 before moving to the C7. A great TV, and so much brighter in HDR than the C7 (it wasn't even close), but yeah... those vertical light bands are just not ideal.

Not personally? I use Warm 2, and don't notice a green push.

Has anyone figured out how to get around the A/V sync lag in ARC audio mode? It's really obvious connected to my LG C7 65" that there's between 25 and 100ms of lag (depending on the source) where the audio is behind the video when connected to my Sony HT-ST5000 soundbar. If I switch to the TV's built-in speakers, there's no lag. It's especially annoying when playing video games, too, where sound effects are just a little delayed. It's easy to check, switching back and forth between ARC and the C7's built-in speakers.

That's where it was. It's such a bummer though that HDR 10 while using "PC Input" has broken colors (when watching a UHD Blu-ray or playing a PS4 game) with the latest firmware and that using active HDR by setting dynamic contrast to low is impossible while in "PC input" -- whether using the cinema or game preset.

Active HDR merely applies a different "mapping" of the image based on the TV's capabilities. It comes down to preserving highlight details vs overall "punch."

I suspect that down the road LG may add it to its own menu setting if possible without having to wait for 2018 and beyond hardware. I read that they "hid" it within dynamic contrast low due to time constraints. it was a last minute implementation.

I have a similar recollection except it wasn't a last minute implementation but a last minute decision to have the option of being able to turn off Active HDR. That is according to John Archer.

"Apparently Active HDR was initially designed to be a feature that was on by default and couldn’t be turned off. At the last minute, though, LG decided - wisely, as we’ll see - to let you turn it off. The only problem with this last minute decision is that there’s no Active HDR menu option; to turn it off you actually have to deactivate the Dynamic Contrast setting when watching HDR content! As if the issues around HDR weren’t already complicated enough…"

Does anyone know which power button on the E7 you use to make sure the auto compensation cycle runs when powered off the top left button or top right?

I am playing the panel lottery, as I am seeing banding in content with over 100 hours logged on the panel and multiple compensation cycles ran I called up London Drugs and they confirmed they will pick the TV up for me and give me a new one within the week. However they need pictures showing what I am speaking of issue is my room is so bright during the day even with the blinds closed that you can't see anything so tonight I have to take multiple pictures showing examples such as Marco Polos episode 3 show, the in menu bars in the grey menus, passengers space pan scenes etc.

I wanna be sure the TV runs one more automatic compensation cycle before I take the shots just to see if anything has improved and I proceed with replacement.

I may have made the mistake of manually making the TV run the 1 hour compensation cycle too many times which I've heard can make things worse.

New panel will only be used running slides for the first 100 hours and I will turn it off every 8 hours or so for the automatic compensation cycles.

Very impressed with the near blacks on the C7, a real improvement over my E6, in both sdr and hdr. With my E, I had to make adjustments, none needed on the C7...don't find my self changing brightness setting for different movies in hdr10 as well...LG delivered with these...of course the one caveat being the slight banding...but their barely noticeable.

If I switch to the TV's built-in speakers, there's no lag. It's especially annoying when playing video games, too, where sound effects are just a little delayed. It's easy to check, switching back and forth between ARC and the C7's built-in speakers.
I've only noticed this within the LG YouTube app; my Sony UBP-X800 YouTube app menu sounds are in sync. haven't noticed it in movie menus or games on PC or PS4. Onkyo TX-NR646 5.1.2 setup.

I assume you're going through the receiver to the TV, though? This is an ARC issue.
