Hi guys . as a work around . Web OS can remember the last input that was selected. You can change the input to one of the HDMI inputs so that whenever the TV is turned ON it will go to HDMI and just scroll through Random Beautiful Pictures saying No Signal . Another work arount is do an auto Scan or Auto tuning for live TV without Antenna or Cable connected so that it will not detect any channel, if it will not detect any channel , whenever you go to live TV it will just scroll through random images showing No signal.
I hope LG can add a setting that can let the user to choose BETWEEN booting up to Inputs like what its currently doing AND booting up directly to the Homepage .
I love the current setup because I use a Set Top Box and it works great but it will be better if there will be a settings like what I suggest above .
