The Xbox One X is the only console that has HDMI 2.1. Xbox One S has HDMI 2.0.

The Xbox One S and One X both use HDMI 2.0,

The Xbox One uses HDMI 1.4

The Series X will have HDMI 2.1.

Get a 1xHDMI IN to 2xHDMI OUT splitter and a total of 4 HDMI leads.

1. Plug the HDMI lead from your cable box into the HDMI IN port on the splitter

2. Plug a HDMI lead into one HDMI OUT port on the splitter and into the HDMI IN port on you xbox

3. Plug another HDMI lead from the Xbox One into HDMI 1 on your TV (lie normal)

4. Plug one last HDMI lead from the other HDMI OUT port port on the splitter to HDMI 2 on the TV

Now you "should" have the Xbox One on HDMI 1 with TV and all the bells and whistles but if you use HDMI 2 then you should still have access to TV directly. Please note I haven't tried this yet (sitting here waiting for my Xbox) but I might have to if my
wife hates using it through the Xbox, however I see no reason why it wouldn't work.

For those with with Home Theatres with HDMI

Cable Box HDMI Out to Xbox One HDMI In

Xbox One HDMI Out to Home Theatre HDMI In

Home Theatre HDMI Out to HDTV In

.

If using optical audio for sound, connect the toslink from the Xbox One to the HT.

There will only be on HDMI going to you TV. That one HDMI cable will be the one used for your Xbox One. Everything else is going to the Xbox One. So, its not the TV trying to figure out which HDMI cable or setting to use, its the Xbox One.

Hope that helps a little
