The ASUS TUF VG27AQ can be used with the Xbox Series X, but there are some specific considerations to keep in mind:

## Compatibility
The TUF VG27AQ is compatible with the Xbox Series X, but it requires some settings adjustments to achieve the desired performance.

## HDMI 2.0 and 120Hz
To use the monitor with the Xbox Series X at 120Hz, you need to use an HDMI 2.0 cable. Here are the key parameters and steps:

- HDMI Port: Use the HDMI 2.0 port on the monitor.
- Xbox Settings: On the Xbox Series X, you need to enable the HDMI override for 1080p @ 120Hz. This is because the monitor cannot take full advantage of the Xbox Series X's capabilities at 1440p with VRR (Variable Refresh Rate) enabled. To do this, go to the Xbox settings, navigate to "Display & Sound," and enable the "HDMI override" option to allow 1080p @ 120Hz.

## Additional Notes
- Resolution: The monitor will downscale 4K signals from the Xbox Series X to 1440p, which is useful since the console only supports HDR in 4K.
- VRR Limitation: Note that enabling the HDMI override will disable VRR on the Xbox Series X.

By following these steps, you can use the ASUS TUF VG27AQ with your Xbox Series X at 120Hz, although at a lower resolution of 1080p.
