It seems to me that I'm seeing a lot more variability in the quality of the picture than I did with my Panasonic plasma. Sometimes the picture (I'm talking about resolution) is quite remarkable, while other times it seems sort of fuzzy -- but very slightly so. And when they show stuff that is really old, it really looks krappy (which is to expected). Maybe it's just my imagination, but sometimes the degree of resolution even seems to vary from commercial to commercial.

Assuming there is nothing wrong with the TV and nothing wrong with my brain (the second assumption might be debatable), why would it be that the C8 would tend to show more variability in terms of the quality of the 1080p picture? In other words, why would I notice the difference in the quality of the source material less on my previous set?

Has anybody else experienced this?
What is your setting on the Genie? Is it set to output "Native"? (On my HR24, this is under Settings -> Display -> Video -> Native). If you turn it to On the Genie will output the resolution that it is receiving. So if the TV station you're watching broadcasts in 720p for example - the TV will get a 720p signal and will upscale it to 4K. If you don't have native turned on, it may be outputting the 720p signal as 1080p meaning the Genie is upscaling it and then the TV is upscaling it again. Native does take longer to change channels because it has to change resolutions and redo the HDMI handshake, but try it and see if the picture looks better.

You do have to remember though that for lower resolution signal sources, you're having to "make up" more pixels which can cause more fuzziness or visual artifacts when upscaling.

UHD 4K has 9 times the pixels as 720p, 4 times the resolution of 1080p (and sort of 4 times the resolution of 1080i), and 27 times the resolution of 4:3 480p

The viewing distance is about the same (10' - 12').
When you hit the 150 hour mark the detail will just pop. You may be past this mark. I thought that mine was not going to give me the detail and crispness I was used too. Then around 150 hours I woke up one day turned it on and walla the definition was there. This may not be the case in your display but I saw a big change at around this mark. You may be past this mark, but mine is getting better every day.
Also always remember the the mouse remote is worth the price of the display. I am really enjoying the remote.

I'm not really familiar with those, but...

I would make sure they are set to the right output range, either Limited or Full. Different devices call this setting various names. On the LG it's "Black Level" which you've said is set to Low. You could switch to high while watching something and immediately notice if the problem is corrected.

I would also make sure those devices aren't changing or modifying the picture(source) in any way. You want a pass-through or direct mode if available.

If you're not familiar with these devices then I would suggest you take time to go through the manuals and check forums for any tips. (like this and device forum http://forum.zidoo.tv/index.php?threads/psa-the-x9s-outputs-wrong-color-levels.5054/)

Crazy thing is its only a couple inches bigger in outer dimensions than the old one due to now bezels.

Hello,

I was watching The Haunting At Hill House on Netflix last night. It has Dolby Vision and Atmos and I noticed on my OLED 65C8 during the intro when it was on a gray it has diagonal lines. I don't know if it is on the series that I'm watching or on the TV. I don't see any problem when I watch other movies or TV. That part only when the screen is whole gray.


Watching Netflix on LG WEB OS in 4k UHD


I've noticed as well when any scene that is very dark I notice noise from the blacks. Is it from the camera or from the TV? Source is a Blu-Ray UHD LG UP970. The blacks are nice but it is just during a really dark scene that has a minimal light on the movie or series.

I also had connection issues when TV was connected to both lan and wifi at same time. TV seems to be trying to 'bridge' the two connections which is causing 'handshake' problems and various other issues while streaming content from Netflix for me. I have no problems if I eliminate either one of them and use the other.

Noise coming from dark or black areas of the screen when streaming can be caused by many things, other than the TV. The cameras used to record low light conditions, compression processing by Netflix, and to a much lesser extent, the TV and it's settings. I would only use UHD disks to evaluate TV side of things.

We watched episode 4 last night, via Netflix on an ATV4k and it excellent. I don't use the LG's WebOS nor the apps on the LG UBK90. Didn't see any "abnormalities".

Why would you be connecting to both at the same time? If you have a wired connection, just use a gigabit switch so that all of your devices are hardwired. That's what I do. I never use WiFi for my HTS.

In my case, I had been using wifi, and never realized the tv maintained it's wifi connection when I added the lan cable. I think in some cases, people have had better speed through wifi than lan, although, I have never experienced that myself.

I guess the camera used in extreme low light makes the noise. I see that also sometimes in a UHD disc.

It is only that part after the first scene and it goes to intro which has the full gray screen. I would check again later. I was just at episode 2 and the story is very nice.

Our speeds are pretty much the same whether it's WiFi or ethernet. I just prefer to use ethernet to eliminate any possibility of WiFi interference because we have lots of devices on WiFi all of the time. We use a mesh WiFi system for speed and coverage but the HTS is hardwired with solid core CAT-6 cabling. I just figured I'd have the CAT-6 cable installed while we were wiring for the speakers.

First thing is make sure Dynamic Contrast is off when you use Technicolor Expert for SD content. It's easy to see the negative impact on the picture when its on, it should be enable if you choose this picture mode for HDR. Do not change the black level setting from the default of Low, despite what others might suggest. For SD drop the OLED light to 40-50 range to start, contrast at 85, color at 50.

What did you use to adjust your white point settings? Those shouldn't be messed with unless you have a meter/calibration equipment. Changing those can do more harm then good, I'd set them back to the default values to start with.
Cam1977 and icic2018 like this.

There is no perfect display, quit looking for faults and enjoy

Do not change the black level setting from the default of Low, despite what others might suggest. For SD drop the OLED light to 40-50 range to start, contrast at 85, color at 50.

What did you use to adjust your white point settings? Those shouldn't be messed with unless you have a meter/calibration equipment. Changing those can do more harm then good, I'd set them back to the default values to start with.
I don't think any of that matters for what he/she is complaining about, which is gray blacks. The only time you'll get that is if your brightness is too high, or there's a mismatch with the output range, hence switching Black Level to High to match his source. (or the panel is really messed up)

That's why I asked for pictures to see what is happening.

If you don't have native turned on, it may be outputting the 720p signal as 1080p meaning the Genie is upscaling it and then the TV is upscaling it again. Native does take longer to change channels because it has to change resolutions and redo the HDMI handshake, but try it and see if the picture looks better.
My Genie did, in fact, have the Native setting set to "off." When I switched it "on," I seemed to notice an immediate improvement. My room is quite bright now and I didn't close the blinds so it was a bit hard to tell, but the logos on the screen and other writing seemed to be instantly sharper. I'll check it out later today with a darker room when I have a chance.

Thanks so much for your help. Love this forum!


UPDATE: I did check out the picture later today and setting the Genie to Native made a huge difference for me. Everything is perfect now, and I can't believe how good the upscaling and picture quality is on the C8 now.
LiQiCE, I WANT MORE and smurraybhm like this.

That's why I asked for pictures to see what is happening.
And I stayed at a Holiday Inn last night I "think" some descent settings might help our forum member, pictures tend to make things look even worse. They asked for some ideas on settings, so I responded to what was requested. Try playing around with Dynamic Contrast on SD content, its easy to see how it will gray the blacks. Then jump in and start changing your white point settings, you'll end up with a wonderful picture (that's sarcasm to be clear).

I hope I can send DNice some pictures and he can calibrate my displays from South Carolina

There is no perfect display, quit looking for faults and enjoy

I have a Zidoo X9S so I imagine it is very similar. Mine looks fine, blacks are very black. I do notice the quality of the exact same video (rip from my UHD disk to play through Zidoo vs actual disc in LG UP970 player) is better from the UHD disc player. Not with black levels, but with banding in colors in a sky, things like that.

Anyway, here are my settings. In your Zidoo main screen, go to Quick Settings, then in:

Playback -> Automatic Frame Rate -> set it to Switch frame and resolution.
Display -> HDMI Mode -> Auto
-> Screen scale -> 100%
-> Picture parameter -> defaults
-> HDR -> ON
-> Advanced Settings -> Deep Color Mode -> Auto
-> Color Space Mode -> YCbCr 444
-> HDMI Range Mode -> 16-235


On the TV, for non-HDR material, I use technicolor expert mode, settings:
OLED Light - 80 (daytime bright room, will lower to 50 or so at night/dark room).
Contrast - 86
Brightness - 50
Sharpness -10
Color - 50
Tint - 0
Dynamic Contrast - Off
Super Res - Off
Color Gamut - Auto
Gamma - 2.2
White Balance - All default except Color Temp to Warm1
Color Management - all default
Noise Reduction - Off
MPEG Noise Reduction - Low
Black Level - Low
Real Cinema - On
Motion eye Care -Off
TruMotion - Off

For HDR (I dont have any DV sources on my Zidoo, so this is with HDR10):
OLED Light - 100
Contrast - 100
Brightness - 50
Sharpness - 0
Color - 50
Tint - 0
Dynamic Contrast - Off
Dynamic Tone Mapping - On
Super Res - Off
Color Gamut - Auto
Gamma - 2.2
White Balance - All default except Color Temp to Warm1
Color Management - all default
Noise Reduction - Off
MPEG Noise Reduction - Low
Black Level - Low
Real Cinema - On
Motion eye Care -Off
TruMotion - Off

Hope that helps.

What are you using for HDMI cables? While what your describing isn't the typical issues seen with marginal cables, I'd want to make sure I was using some that are premium certified. Finally, have you tried any other sources other than the z20 with your display. There are some dolby vision/atmos "samples" available via the apps on your display - exact app name is escaping me. Plus various other streaming options via the internal apps. If you had the elevated blacks with other content then a display problem would be very likely. Still think its something that isn't set up right between the x20 and your LG.
