A guy posted earlier about something like this and said to go into settings and make sure just scan is set to on have you tried that.

TV manufacturers are huge corporations that want to stay on good terms with the studios, so they're not going to invest much in making rip playback too easy. nVidia and other streamer manufacturers don't have the same kind of business relationship with the studio system that Samsung, Sony, etc. do.


I disagree, especially if you're strictly discussing 4K playback. The Shield's 4K playback is flawless. There are some issues of varying impact with resolution, scaling, and colorspace mapping that affect lower quality sources, though I think those get overblown in forum discussions. But this is not the place for the argument.
That’s fair enough. But since this can be a discussion for devices best suited for the LG OLEDs over the built-in software in the TV, it is still “relevant.” The Vero 4K, from a pure playback standpoint, is the more reliable device. Based on reading a lot lately, many have ditched the Shield for the Vero. It just works.

In any case, the key was to get the word out there that XPlay or the built-in player on the OLEDs doesn’t work properly. It’s close, but no cigar.

Yes I always have that on and use original aspect ratio. Anyway I turned pixel shift off just as a test and wouldn't you know it, this feature was causing the display from my PC to be shifted off the edges slightly for whatever reason. I assumed this feature was to shift a static image periodically but I'll admit I'm not 100% sure how it works I just know that for PC usage I have to have it off. Not that I'll use the TV as a full on monitor, I don't want to burn the screen in with my desktop but I do use the TV for gaming which includes my PC so I have to have access to the desktop to load up my games.

2017 LG OLED C7 screen jumping on PC after Firmware update.

2017 LG OLED C7 screen jumping on PC after Firmware update. After I updated the screen does the weird jump for lack of better terms. For example, the screen act as if it was doing a minor zoom in like a camera or auto focus or stutter. It only occurs on my PC while watching Netflix the video or image doesn't do this. I've updated to the latest firmware via Korean site 04.70.76

Odd that you perceive more shadow detail as a result of bias lighting, the opposite would be expected. The bias light results in some constriction of the iris of the eye and , where black levels are not very deep (think some LED TVs) there will be a resultant perceived deepening of those grey/blacks. This can result in some loss of shadow detail.
I don't think many of us use bias lighting with OLEDs to increase perceived contrast but rather to prevent the iris from having to open and close constantly as screen light levels vary in a darkened room. This is the reason why eye strain is reduced by bias lighting.

confusing post, so it only does it while watching Netflix on the PC or doesn't while watching? Not sure why you would watch it there anyway but I am guessing the issue goes away when you watch Netflix on the PC. This sounds more like a PC resolution issue, graphics card, driver or settings within etc.

worth the time to replace even if it goes away like you are seeing. The fact that they will replace it with an new one is the best route anyway.

I was watching Mad Max on the 65B7P the other day and decided I really needed to get the light in my basement room under control. I have horizontal blinds on this window but they just don't cut it this time of year with the sun streaming in. I didn't want to put anything outside the frame so decided to make this portable plug out of 1" pink styrofoam board. Put a handle on it to make it removable, beveled (and painted) the edges and applied this poster. Before you think what I did here is weird, let me tell you i've done stranger things...

After getting my C7 I did a lot of reading on this thread, the 2017 LG OLED calibration thread and other publications (CNET, Rtings) about various recommended picture settings. Tons of great information and recommendations by many contributors. Understandably, most of the settings listed were geared at calibrating the panel to a specific standard, which is logical. We’re told that’s how things should look. But, one piece of advice I kept seeing from some posters that stood out to me was use the settings that look the best to you for your specific environment and panel. After trying the settings that were geared at bringing the panel close the “standard”, I messed with the settings to get it to where it looked good to me. Now, I have my C7 in a room that has a lot of light coming into it during the day. Large floor to ceiling windows that run the length of 3 of the 4 walls. Tons of light coming in during the day. The C7 is used for everyday TV watching with DirecTV and the Apple TV 4k (streaming movies, Netflix, Amazon, Infuse, etc.) being the primary sources. I’m still doing some minor tweaks on these here and there. I know I’ll likely get flamed for various aspects of my settings but so far here is what I have found I like for my setup. I’m posting them in the event they help someone else get to where they want to go with their settings.

Thanks for posting - very helpful for folks who have a lot of ambient light. Do you change any of these settings at night, assuming the environment is much darker? And a related question - is there any way to save settings for different environments and toggle between them?

LG told Vincent Teoh that adding dynamic tone mapping to game mode isn't possible for the 2017 sets due to hardware limitations.

Pretty annoying...

The set is 5 months into its 1 year warranty.
Thats a great question, the old unit may last forever, where the new unit could break in 3 years......who knows right? Glad you are covered now, but this is why extended warranties exist....

Question Lg oled c7

Hello,

I am having weird issues with My LG OLED 55"C7 in regards to judder/horizontal lines when playing any content on Windows either via Kodi or VLC.

However when I play it via LG's built in Photo & Video App the content plays flawlessly and beautifully. What coudl be causing this. Its the same content streaming from my FREENAS server.

So far I have not done that as we tend to watch with the overhead lights on (but dimmed) and some accent lighting from table lamps. We tend not to watch it in a "movie-room" setting with little to no ambient lighting. It's more of a general use TV for us (and an awesome one at that!). I've thought about doing a PM setting for the rare occasions when we do watch a movie with almost no lights on. If I go that route, I'll guess the ISF Expert mode (either light or dark) might be a good choice given its similarity to Technicolor Expert mode and adjust OLED light down, etc. And, just toggle between the modes as needed. Not elegant but workable. It would be nice if the TV could use it's internal clock and location to switch to a different PM (one for night viewing) at a specific time...say 1 hour after sunset and then switch back at sunrise but I suspect it might create more issues than solve.

Chad B calibrated mine last month and I asked him why he chose ISF Dark/Bright for SDR content over Technicolor... and he said

"They are different from the factory but calibrate the same."

That was good enough for me... didn't really feel a need to question someone who has been calibrating panels professionally for 15+ years.

Just throwing this out there is case anyone has any doubts... go with whatever floats your boat but at the end of the day not going with Technicolor isn't gonna ruin your experience. Mine is quite astonishing across all picture modes.

I watch in a dark room setting.

Just throwing this out there is case anyone has any doubts... go with whatever floats your boat but at the end of the day not going with Technicolor isn't gonna ruin your experience. Mine is quite astonishing across all picture modes.

I watch in a dark room setting.
Do we know that the imminent upcoming Technicolor upgrade, plus great new thing that Sonoftrumble has talked about, and which may or may not, actually be the same thing, won't produce the need for a change to these sittings?

That's pretty much a rhetorical question where you are concerned, as I'm quite sure that you don't know the answer, nor do I. The point here is that absolutes are most likely ill advised where fast moving technology is concerned. It could very well be that your calibration would be eligible for a tweak when the new stuff hits the pavemant.

Is there any info anywhere about the imminent Technicolor upgrade? I thought that was a myth.

@sono ftrumble had posted in this Thread that we will get Technicolor HD plus other major upgrades. I think he may work for LG.

Gotcha. That rumor has been going around for a while. Probably just a rumor then. But here's hoping.

I doubt I'll need a tweak. If they are upgrading a picture mode I don't use I don't see why I'd need a tweak. I've already been told by the guy (who's opinion I value pretty highly given his reputation across the AV world) that ISF Bright/Dark is fine and calibrates the same as technicolor... a bandwagon I'm glad I didn't jump on otherwise I might have doubted him.

Either works... and (according to the same expert) one isn't better than the other.

What's funny is I use the ISF Bright/Dark for SDR content... and even though it looks out of this world good as far as SDR is concerned it's still by far the content I care the least about when it comes to viewing. HDR 10 and DolbyVision use Cinema (User) anyway.

Pretty gutsy, accusing Sonoftrumble of rumor mongering.What support do you have for that remark?

I saw this update once. I was camping in the woods with a buddy when we both heard a rustle in the bushes near by. As we turned around to look, this update jumped out. It was the most amazing thing I've ever seen. Unfortunately, I wasn't able to get my mobile device out in time to snag a photo.

B7 display issue

I have a display issue that I could use some assistance on.

Summary of my setup:

B7 is on the wall above the fireplace (approx. 5 feet from the floor) slightly angled down
HDMI cable run through the wall to Yamaha receiver, all components connected to receiver
Components consist of Oppo UDP203, Apple TV 4K and Comcast cable box

I bought a B7 back in Sept. 2017. Over the winter, I noticed a transparent horizontal line that runs across the screen approx. 1 inch from the bottom. I noticed the line most often with 1.78:1 content, but I sometimes noticed the line with 1.85:1 and 2.35:1 (traveled with the image and didn't stay at the bottom of the screen). The line was much smaller with the different aspect ratios, but it was noticeable if you were looking for it. It did not matter if the content was from the Apple TV, Oppo or Comcast box.

To troubleshoot, I've tried a couple of things.

1. I've toggled 'Just Scan' on and off and played around with the aspect ratio settings. Line still present.
2. I simply switched the main HDMI cable from input #2 to #1 . Line still present.
3. To hopefully rule out my HDMI cable, components and receiver, I connected a separate Apple TV directly to the TV via a separate HDMI cable. Line still present.

I made the assumption based on these tests that the issue lied within the display and not any one component or cable. I submitted a trouble ticker to LG and a local representative from an A/V service company came to my house. He agreed he could see the line, but when he did a video call with LG service the technician could not see it via phone. Therefore, they would not do a screen replacement, but said he could swap out the video card.

Before, I did either I wanted to get some opinions. I can follow-up with some pictures, but it has been a bit challenging to capture the issue with a camera.

Any suggestions on additional troubleshooting to do or follow-up actions would be welcome. Thanks in advance.
