Resurrecting this old thread because I learned a couple of things recently. First, for those who use the built-in apps (Netflix, Youtube, etc.), there is a way to adjust video settings that I wasn't aware of before. How?
Open an app like Netflix and actually start playing a video. Just having the app open won't work...you need to be actually playing something. If you don't have a Netflix sub, try Youtube, but actually play a video. While a video is playing, press the Q-Menu button. At that point you have some basic options to make video and audio adjustments (although in my experience, audio adjustments like bass/treble have never worked for me).
Why is this important? Because you can match your app video settings with your other calibrated video settings, and you can turn OFF things like Tru-Motion. Tru-Motion for Apps doesn't have a "Custom" setting, though. I use a Custom De-Judder 0 / De-Blur 10 on my other inputs. Can't do that in the Apps settings. It's either low/med/high/off.
Second thing I found useful is the Android LG Remote (2011) app. There are a couple of LG Remote apps in the app store, but the most recent one won't control this set. You need the (2011) version. It has all the functionality and then some of the Magic Remote, and made inputting text, pointing, menu options, etc., a breeze. I see there's also versions of these apps for IOS devices, too, so you should be good to go.
