That picture looks nice. The bright colors are not usually the problem. I'm playing with the tv now, and it has a nice picture until things get really dark. I think the corner backlighting on my set are acting in an inverted fashion. On dark scenes they start bright, and on lighter scenes the backlight makes the picture in the corners a bit darker. Or the backlight in the corners just isn't working properly.

Reflection is pretty bad in a bright room. I'm still Loving LG interface. I will miss it if this tv doesn't pan out.

Side note:. I used the c8 oled color and white balance settings. I really like the color. I can't tell if I could get better luminance without a meter

Is this only a problem when your viewing with letter box bars
There is a way to eliminate black bars permanently from movies, I call it the IMAX aspect ratio. It's one of the main reasons I'm buying this tv

My set has the issue when there is an image with no black bars. I don't recall if it was present when black bars were in place.

I got a chance to check the TV out a bit last nite. I recommend two separate settings for HDR / TV content and standard movie contents. The settings on RTINGs for the 6570 is a good start as it's pretty comparable to this model.

Depending on the source or content you watch the TV may be detecting it differently but I noticed it always applied a super high back light setting even under ISF Dark Room.

To combat the washed out look I had to lower back light significantly. In my low light room I'm at 30 on backlight and 90 contrast. With Dynamic Contrast on High it's a good PQ with minimum effects like you're seeing.

So what do you guys think about them removing the local dimming description. To me it stinks of bait and switch.


The 6570 was several hundred dollars cheaper.



I wonder if Costco or LG would offer a rebate to make up for this scam.... Really bad business practice imho.


Almost feel like rejecting the TV on principle.



All that is beside the point that I'll probably be happy with the image. If something was sold with a certain spec, then it should have that spec.


All the hemming and hawing is frustrating.


What do you guys think about this?

Agreed but even minus the local dimming, the 7570 is heads and shoulders above the 6570

First off the 6570 has no atmos or atmos over arc
And it has dolby vision, and ultra luminance

The only set you can get that's 85inches that has dolby atmos and dolby vision is the 7570 and the 900f that's 2k more then the 7570 at 4500k vs. The 7570 at 2499

That's a good point. But it doesn't take away from what appears to be a bait and switch tactic.



If they had sold the TV highlighting only those included features, then at least peoples expectations would have been set properly.



Like I said, I'm probably going to be very happy with the image quality and with the features you mentioned. It just makes me mad to think about a company purposefully lying about their products and tricking consumers. It makes me want to reject the LG brand and spend my money on a more honest company even if it costs more.


I just LG to come out and be honest and make it right for us early adopters....

They should easily be able to add local dimming , frame dimming is a soft version of local dimming anyways, it can be done

I think they made an honest screw up. I believe Costco got the prerelease version of this tv and it slipped through without the local dimming added. Or the 7570 spec sheet is for a higher end model not yet released.

It wouldn't surprise me if someone got into service mode and was able to enable local dimming.

if its not built for local dimming then there be no way to add via firmware. each zone would need its own driver for independent control.

Agreed. Zone based dimming is not trivial and needs both hardware and software to implement.

I think the 6570 got Dolby Vision added to it in an update, all the sites list Dolby Vision for it. even LG's own site.
I don't have a Costco locally yet, so had to order the 6570 instead and am hoping the Dolby vision listed is correct for that model. Does anybody know for sure that the 6570 won't passthrough Dolby Atmos? Maybe it got updated as well.

Check the bottom right on this Samsung MU6300, in the 50% gray and black uniformity photos. VA panel so the backlight bleed is not as noticable, but similar symptom in a direct lit panel without local dimming.

Check out some other rtings reviews, especially IPS panels, and you will see similar. The corner light dim but elevated black levels seems worse with edge lit panels, but is also present on direct lit panels. Both edge lit and direct lit panels use light guides as the entire back is not covered in LEDs even on direct lit, but the light gives have more work to do on edge lit panels, so my speculation is that the uniformity issues seen are in areas where the light is less direct and it "sprays" past the edges of closed pixels on black scenes but is dimmer in those spots on bright scenes as the open pixels further from the light source are getting less light. So i guess I'm saying the pixels are unable to block out as much light due to the angle of the light while at the same time they are not receiving as much light so they are dimmer when open. And it's magnified on IPS panels.

Given the recent updates on potential (at least current) lack of local dimming, it seems the differences are close to nonexistent.

To me It's looking like if the 7570 doesn't have local dimming then the only difference really is the 7570 does Dolby Atmos/passthrough.

It'll be a few days before I'm able to try the advanced isf settings on the 7570. Can someone try the following...While in isf night picture mode, hover the magic remote over isf night. While hovering over isf night, use a 2nd remote (harmony or cable box remote) and enter one of the following codes (0413, 7777, 8741, 8743 or 8878). If any of the advanced calibration options were previously greyed out, they should no longer be and the local dimming options should be in the advanced picture settings.

Can you be more specific. Hover over it where? There are 3 screens on which you can hover.

I have a DirecTV remote that is sync'd for LG and can enter those numbers, but need clearer instructions.

Here's how it works on my LG 84"...the menu's may have changed substantially on the newer models??


Go to Settings, Advanced, Picture, Picture Mode, then hover over the isf Night picture mode and enter one of the following codes (0413,7777,8741,8743,8878) with the 2nd remote. That should open the advanced (Picture Adjust) sub menu. From there click on Picture Adjust and then Picture Options which may lead you to Local Dimming.

Hope this helps/works...

Tried it. Nothing happened. I somehow changed my isf Expert (Dark Room) to isf Night now. That wasn't there before and I'm not sure when or how it changed, but it was while trying to input the codes.
