So flipping through the manual, it looks like there's seven total inputs allowed (6 HDMI and TV for ARC) plus the Tuner and Bluetooth. Counting the Bluetooth input, that's three more than the 975.
That's a cool count, and six years ago it mattered to me...
Oppo
Nintendo Wii (Only the one gaming system for me!)
Laserdisc
Legacy S-VHS
HTPC
Aux input for MHL (phones)
Roku
Dish Tuner
WD Media Center
But that was then. Now it's down to...
4K BluRay
Roku
And the only reason for the Roku is that my TV is a (2-yr old) top-of-the-line Samsung Tizen, which means great picture, terrible apps and software. It sort-of supports a lot, but the Roku is more reliable. Still have a PC and Nintendo, never turn them on. Cut the cord a long time ago also. The rest have been replaced with TV or Roku apps/channels or casting and the ethernet.
Out of curiosity, how many devices do you (forum at large) regularly use?
Quite a few, 3 with HDMI and 4 analog.
Having looked at the manual, I would have liked to have the ability to re-name the inputs which isn't available.
