I see that if you just turn on the tv, your last-watched input will conveniently come on 120 seconds later. Really, this is a ridiculous amount of time, especially since you can scan what is on the screen visually in 5 seconds and decide if you want any of the selections.
I reset my tv to factory to clear out all of the software updates. Worked perfectly the first time...screen came up exactly like I wanted. Then a message popped up that my 'Home Screen' was updated for my viewing pleasure or some stupid message like that. I went through the menus and don't see any way to simply turn off this updated 'Home Screen' setting. Really annoying. It is the same Home Screen display that I was getting when I had the latest software installed...so maybe Home Screen is controlled separate from the installed user software. Regardless, it is really a stupid Home Screen, and the end user should be given a chance to turn it off. I have 2 older LG TVs that I really, really like. That was the reason that I bought this one...not knowing the WEBOS rabbit hole I was getting into. Won't be going the LG route with our next tv unless LG gives the end user an option to turn off 'their' home screen and give me an option to set it as I wish...which is like their television pre-WEBOS.
Edit: To be clear, my WebOS tv is a 32LM570BPUA now running 4.10.0-12 The 'Home Setting' doesn't allow changing any of the settings that really would de-clutter the screen. Perhaps the software in some of the newer models allow this, but not in this tv that I can find.
Edit: Well....'something' I turned off has caused the home screen to turn off for me. I don't know what I did, but I'm not going to fiddle with it any more. This is how I've always wanted it. For those with this software version on their tv, I was in the: all settings> general > additional settings menu and then turned off everything but the screen saver. I'm thinking turning off 'QuickStart+' is what did it for me.
