LG OLED C7 Vertical Banding Issue
« on: January 18, 2018, 22:22 »
Dear owners of LG C7, E7, G7 or W7 OLED TVs,
I would like to request your assistance - to post pics of your TV showing 5% gray slides here, using this Youtube clip:

https://www.youtube.com/watch?v=Qi4Wy7vE8-o

The reason is because I think the vertical banding on my 65C7 is quite bad (sometimes visible during normal watching), but LG Service came down to see and said that it is normal. I have seen some pics of this model with 5% gray slides (from friends and google images), and mine seems worst than most of them. So I'm trying to do a comparison with other samples, to see if there is ground for me escalate this matter with LG. 

If you don't want to post here, you can also PM me. Then can whatsapp me your pic.
Thanks everyone! :)

Here is a scene where you can see the banding clearly. Notice how the right side is darker and the dark stripe on the right just off-centre. Mirroring the vertical bands on the 5% grayscale pic above.

I wouldn't say the real thing is worst. It is visible during dim panning scenes. Not visible 95% of the time, but given the price, I don't feel it is acceptable.
Here is pic from my friend's 65C7. A lot smoother.

This is not covered by warranty?

According to the LG technician, this is usual for IPS panels, and is not a defect.  Not solveable, but not a defect covered by warranty.  Are OLEDs IPS panels?

Here's my 55" C7. The funny thing was that I had have my TV set to a dark mode and I couldn't even see the 5% with the lights off :).

Here is 5% in the dark. Note this is a really grainy photo with lots of noise because it's so dark. I think that makes it look worse than it really is.



Here is 5% with the lights on. Yes my desk is a mess :).



Here is 20% with the lights on



Honestly, this doesn't bother me on my set at all. Especially when my TV is on the Expert (Dark Room) mode and I can't see it ;).

Hi DH, how is the 5% slide looking on your C7?

Some banding. But not noticeable in normal viewing   The white bars are light streaming from my windows.

Thanks DH. Your pictures of the screen are very dark. Can you put on a brighter mode (eg. expert bright), or take picture with room lights on?
