Solved I found it. Hope this helps other people like me.
Press Home on remote
click Home Dashboard on bottom left
top right clicks 3 dots
click Edit Inputs then click the icon left of your HDMI and set it the PC.
My only options are set top box, Blu-ray, DVD player, home theater, OTT. Is there a way to label it?
Also can I remove trending or all the other stuff on the home page?
