Okay found a "solution" or "temporary work-around".
If I changed the input to HDMI (DTV)
instead of HDMI (PC)
I was allowed to manually change the settings for height placement of the input. HDMI (DTV)
has the problem of being constantly zoomed in and I was unable to zoom out, but if I changed it's height placement value and then changed back to HDMI (PC)
it remembered it's placement from the HDMI (DTV)
I have not yet tried turning it off and back on and see what demons that spring up when I do, but for now it's fixed.
I found out how to go into the Service Menu
, but none of the 6 standard LG passwords worked for me, presumably the person I bought the TV from had changed it. So if anybody happens to know how to factory reset an LG 42LB1R-ZE
without needing to reach the service menu, I'd be greatful to know.
