I recently purchased a LG C9 Oled tv to replace my old Sharp LED tv. I use the tv for movies, tv and it doubles as my computer monitor. It is having a weird issue with auto dimming technology built into it. When I use it to view web pages the screen goes dim, then gets bright again, then dim again and back and forth. It is actually doing this right now as I type this lol. I understand this is a protection feature of the tv to help prevent burn in and I get why they did it. However I don't like it and it doesn't play nice with web pages, youtube or my desktop. HOLY crap it just ramped up again and blinded me lol. Does anyone know if there is way to turn off this feature? I would really like the backlight or whatever it its called on an oled tv to stay where I chose to set it. I know the brightness level I like and don't want the tv making this choice for me at random. I have a harmony remote so I can get into the service menu and instart menu if that helps. I just don't know what I am looking for and don't want screw something up in there.\n\nI called LG and they told me a bunch of stuff to try, like turning off all the auto settings and true motion and all that. Which were all off already. They gave me a list of stuff to try and said to call back if it still did it. I tried them, none of them worked. Which I really didn't think they would honestly. So I called back today and tried to explain exactly what was happening. She had me do the picture test thing, which worked like it is supposed to. She told me my tv was broke and I needed to get it serviced lol. I told her I don't think it is broke. I think it is doing exactly what is supposed to do. I just want to know if I can shut that feature off. I asked to talk to a technician and she wouldn't let me. She said she did already and he said the tv is broke. I finally got her to agree to have a technician call me back and talk with me. I am not holding my breath though.\n\nSo if anyone has any ideas I would love to hear them. And if someone does call me back I will come back and let you all know what they said in case someone else has this issue. Other than the tv works great, I love it. It just doesn't make a very good computer monitor so far. I do understand that is not what it was designed to do though so I am not going to throw a fit about it.
