OLED TV - Same Issues...

A few days ago i was to my ex-wife and looked at regular tv on the Oled-tv and to my surprice i didn´t get any eye strain at all. She lives in a apartment and have cable channels but the picture is not good. It looks like a low resolution analog transmission with grainy, fuzzy picture and for some reason i get no problems with my eyes?
But i have a theory whats wrong and it has something to do with the image processing/motion on todays LG OLED-TV:s.
I have read on forums that people can see judder on the LG B6 OLED-TV and to get around the problem is to connect a external device (PC, Console etc) and choose PC as HDMI-input.
Today i was to my ex-wife and connected my computer to the oled and checked if the 920 has the same judder-problem as the B6.
On Youtube there is video with two balls, one ball at 24fps and a second ball at 60fps (

I have read that the 60fps ball has judder on the B6 with the internal Youtube app or with a device (PC etc) connected to a hdmi-port that is not named PC (Console, DVD etc).
And my discovery is that the 920 has exactly the same motion problem as the B6.
If i play the "ball video" in the internal youtube-app there is plenty of judder on the 60fps ball. There is also alot of judder if i play the video on the computer with the hdmi-port set to something else as PC.
But if i set the hdmi-port to PC the judder is totaly gone.
I also played movies with Kodi/Madvr on the computer at matching 24fps and it was not 100% perfect, but the eye strain was not at all as bad as
with the internal videoplayer or regular HDTV-broadcasts with good picture.

My theory is that some people see not only the image but also see the errors in the image on a subconscious level if the image processing in the tv is not fast/good enough.
The brain gets confused because the conscious and subconscious picture does not match with each other, which leads to eyestrain.
In my case i do not get overworked eyes of surfing the web and as I just discovered of bad television broadcasts on the OLED-TV.
In both cases the conscious (websurfing, bad broadcast) and subconscious picture (errors) is a better match than a "conscious" sharp picture with a lot of "subconscious" image processing errors.
Maybe it´s possible with small steps to train the brain to ignore the errors in the picture?

Jimbo66 Oh wow. Thanks for your post. This is a great discovery!

It would be great if others could chip in about their experience with OLEDs. Did you use the internal videoplayer or did you connect an external device?

Jimbo66 Coming back to this post, I really doubt that the judder went away solely because you set something to "PC" — I think that mode would have changed some other setting, such as edge enhancement. People focus on TruMotion as the only issue I think but I've read that edge enhancement can add noise to the picture and thus cause judder. This judder can mimic the effect of high PWM.

I think the best way to test the OLED TV is to go to the advanced video settings and turn all of that additional crap off. There should be at least ten different things like noise reduction and edge enhancement and what not that change the picture for the worse.

There are a lot of opinions on this thread about OLED TVs but I don't know if everyone tested the TVs by using the proper settings on the TV and by turning all the additional filters off. I really do think Rtings may have been right about the PWM measurements in their review of the LG B6.

@Maxx @MagnuM @KM @ensete Can you please provide your opinion?

Hello, i'm new user here..

First sorry for my poor english, i'm french.. lol.

i'm owner of LG EG910V.. (aka 9100 model for US)

i'm sensitive to RAINBOW effect on DLP projector and also on some PLASMA.

i'm sensitive to PWM or Flickering for LED (for sure)

i can confirm there is flickering or PWM on OLED. (the eyes strain and brain strain are very less stronger than LED backlight TV)
I guess the flickering should be at very very HIGH frequency.

i found a way to enjoy my OLED TV and i hope it will help anybody who's get same issues with our power eyes! lol

Actually i'm using ISF EXPERT1 mode.

Then put this settings :

OLED LIGHT : 100 (it will stop flickering)
Contrast : i put 50 or 60 it depends on your light ete sensibility about white latency retina... (it's magic on oled changing contrast settings acting like changing OLED light ... so you can fix over brightness with contrast setting)

I'm not using screen in full black... so i don't know if my trick will be ok for using in full black room. maybe setting contrast too low will give you a bad pictures.. i didn't try yet.

and disable all processing pictures and don't forget to disable EDGE ENHANCER (on picture mode setting) because i guess there is like flickering with this processing maybe it's just me ? )

i just found the solution yesterday night... but i'm pretty sure it's OK my eyes don't strain anymore when i watching screen.

i'm not sure about "real cinema" if you have to set it ON or OFF.... (mine is OFF to test i will try with ON later )

I disabled TRUMOTION because it seems to give me nausea...

I really hope my post will help.

Don't hesitate to confirm or not my experience.

Enjoy your day.

sorry i can't confirm... i have only iphone 5 ...

or maybe tell what to do to confirm.

what i can confirm is that my eyes don't hurt anymore... the most important is to set up accuratly the contrast with the light of the room. ...

i hope it will help ...

i will confirm that in the next few days.

EDIT :

i think it still something with a bit of eyes strain (it could be acceptable ...for people maybe)
i'm sorry for fake ....... i might have to resell TV ( i need to think about it.) .... i'm not sure..... because i don't know what to buy as TV ?

ckf92 When I tried the TV (I don't have it anymore) for some time I found brightness 100 and contrast 0 (I have a brightness issue) to be one of the most pleasing ways of looking at it. But it still hurt my eyes after a while. The rtings.com graphics is not very accurate, but it looks like the flicker percentage might be the lowest on brightness 100. (Flicker percentage is the relation between highest and lowest amplitude.) Maybe that is what makes things a little more comfortable.

or maybe tell what to do to confirm.

It's a little hard to confirm "no flicker" but if there is any, you can see moving lines through the camera. In this case, they are not black but still quite bright, because the brightness does not drop to zero. The lines are just a little less bright than the rest of the screen.
