My Xbox 360 Only Displays When I Connect It’s Hdmi Cable Through Xbox One’s One Guide

Yeah I use the HDMI 1 port for my 360 and it gives me 1080P, but when I plug my One into that same port it only displays 720P. I even tried using the HDMI cable I use on my 360 and it only displays 720P on my One.

Tried resetting display settings, didn't work. Tested on other HDTV (direct connection with HDMI, different cable), worked fine. Retested on my HDTV, through receiver with different cable, not fine. Retested with same cable, direct connection, worked.

Issue, won't display properly on HDTV when passed through receiver, even though it had as of about midnight CST, while other HDMI devices connected to receiver have no problems. This is an issue because my HDTV only has one HDMI port.

Hi, on the Xbox One X as with all of the Xbox One range, there are two HDMI connections. One is an HDMI-Out and one is an HDMI-In. You will see next the HDMI connector a label describing what HDMI it is. You connect the included 4K HDMI cable to the HDMI-Out
to display the console on your TV. The HDMI-In is optional. It can be used to connect a Cable or Satellite receiver to your console.

This guide will help you further.

So are you saying you plugged your cable box into the HDMI passthrough on the One X?

If the cable box is defaulting to a lower resolution when connected into the Xbox One X's HDMI passthrough, you should be able to adjust the display output in the cable box's settings menu.

When cable box goes through xbox one x the picture quality is degraded compared to when it is connected to tv straight. Not really resolution, theres more noise in the picture. Tried switching hdmi cables, inputs. Hopefully it can be corrected via software
update.

1 - I've got 3 monitors at home and they are all the same model, and they aren't able to display my Xbox 360's images.

2 - I'm using a cable that's HDMI on one side and DVI on the other. According to the vendor I've bought it from, it works fine for connecting the Xbox 360 to any monitor (apparently he's already tried it out).

3 - Yesterday I've bought a cable that's AV on one side (for the Xbox) and VGA + an Audio output on the other. I've tried it out and it works just fine. Yet, the image seems just a bit blurry and, from what I've been told, VGA has a lower quality output
than HDMI/DVI so this is to be expected.

I've also learned how to plug both AV and HDMI cables in my Xbox at a time. Every time I've got ONLY the VGA cable connected to the Xbox, I can see the images on my Monitor/TV. Whenever I plug the HDMI cable to the Xbox (w/ the AV cable plugged), the image
on my Monitor/TV disappears. It seems as if the Xbox is prioritizing the HDMI video output over the AV one.

So, I was wondering, is there any way I could plug the AV cable to my TV and the HDMI cable to my Monitor while at least one of them displays an image? That way, I could turn on the TV and alter the display options in the Xbox for my monitor till it works.

THANKS A LOT FOR ANSWERING Mister Cerb!
