Xbox 360 Video Display Issue on Original Xbox Game

Hi there Hulking Panda,

Thanks for reaching out here in Xbox Forums. I understand there is an issue with playing backwards compatible games on the Xbox 360. I recommend taking a look at the following article to ensure the game is compatible for the 360 : Play
original Xbox games on an Xbox 360 console.

Give this a try and let us know the results.

When playing back DVD Video or videos from Xbox Video, the Xbox 360 wants to encrypt the picture and sound with HDCP. If it cannot properly detect that the display can handle HDCP, or if the display is an older model which does not support it, then the Xbox
360 will show this message. I'm surprised it doesn't happen with Netflix.

A possibility is that there is damage to the HDMI cable or connectors interrupting the Xbox 360 from communicating properly with the display, leaving them unable to share keys for HDCP encryption (this is done continuously while HDCP remains active).

Make sure that you turn on the display first and let it fully "wake up" before starting up the Xbox 360.

Also, if you're using the original yellow/red/white AV cable for sound rather than an audio dongle, check if leaving the AV cable unplugged and only having HDMI plugged in will resolve the issue. If it does, then you might want to route the sound out of
your display to the sound bar rather than directly from the Xbox 360.

What brand/model display is the Xbox 360 connected to? Also, has it worked before on that display?

Hello @LawsonDR!

With issues like these, we recommend checking Troubleshoot Xbox 360 display problems | Xbox Support and Connect your Xbox 360 S or original Xbox 360 to a TV | Xbox Support pages as they contain some solution to the issue.

Full range RGB is the best option for games if the display can be forced to accept it. Limited range would be best for video content, but there are a number of issues with it that may or may not make it optimal or even behave correctly depending on each
app.

Display Discovery should be enabled unless you run into problems with the Xbox 360 disabling resolutions your display supports, or if it doesn't shake hands with the display, or if the display supports throughput of Dolby Digital via digital out or ARC and
the Xbox 360 only wants to output in 2-channel stereo.

Make sure you set the display to 1080p in the xbox 360 video settings.
