HP Omni27 All-in-One PCs - Using an HDMI Game Console or HDMI Video Player with your Omni27 PC

This document applies to HP Omni27 All-in-One desktop computers.
You can use your Omni27 PC as a high-resolution monitor for playing games or viewing movies from devices that display HDMI video, such as XBox or a Blue-ray movie player. To do this, connect the game console to the computer using an HDMI connector or composite audio visual (A/V) connectors.

When the system is in Display mode, the computer is still running in the background. The keyboard and mouse are active and still control the computer. To avoid making unwanted changes to open files on your computer, it is recommended that you save and close all files before connecting to the HDMI ports.
