Display
Change your display output settings from this screen. Display settings include screen resolution and screen dimension (or aspect ratio, either standard or widescreen).
For high-definition viewing you'll need a high-definition TV or monitor, as well as the Xbox 360 HDMI Cable, the Xbox 360 Component HD AV Cable, or the Xbox 360 VGA HD AV Cable. For more information, see Connect to TV or HDTV.
* HDTV Settings: Choose between 480p, 720p, 1080i, or 1080p output resolution, depending on the native resolution of your TV or monitor. The default setting is 480p (enhanced definition, or EDTV).
In some cases you can select an "Optimal Resolution" button, which appears only when Xbox supports the native resolution of the TV or monitor and automatically applies the best setting.
If you are using VGA or DVI, you must choose from among the following output resolutions: 640 x 480, 848 x 480, 1204 x 720, 1280 x 720, 1280 x 768, 1280 x 1024, 1360 x 768, and 1920 x 1080.
Important
If you're using the Xbox 360 Component HD AV Cable, any HDTV resolution that you select requires that you connect the cable's red, blue, and green RCA connectors to corresponding inputs on your TV or monitor. If you're using the cable's composite-video (yellow RCA) connector, you'll see only standard-definition images—not high-definition—irrespective of the HDTV output setting you select.
* Screen Format: The default setting is Normal (a standard 4:3 aspect ratio); select Widescreen to change the output aspect ratio to 16:9 if you have a widescreen TV or monitor.
When using the Xbox 360 Component HD AV Cable, you have the option to select a widescreen output even if you're using the composite-video (yellow RCA) connector instead of the high-definition component-video (red/blue/green) connectors.
* Reference Level or Black Level: If you're using the Xbox 360 Component HD AV Cable, the Xbox 360 VGA HD AV Cable, or the Xbox 360 HDMI Cable, then screen format options include Reference Level. The default setting, Standard, delivers the normal range of white and black levels that your TV or monitor supports. Select Intermediate to increase the level of white and black in the video output. Select Expanded to maximize black level. Reference level is sometimes used to make a picture sharper, and you can experiment with what format suits your viewing pleasure.
If you're using a composite cable, the Xbox 360 VGA HD AV Cable, or the Xbox 360 Component HD AV Cable, then screen format options include Black Level, a setting that applies only in the U.S. and only when the display output is 480i or 480p, such as when watching a DVD. Black level options include Standard, Intermediate, and Extended.
Note
In most cases, Xbox 360 does not support full-screen, high-definition output to HD screens with standard 4:3 (non-widescreen) aspect ratios. (Some HD resolutions are in a 4:3 format and you have the option of choosing an aspect ratio.) If you set the Xbox 360 Component HD AV Cable's switch to HDTV, a connected console will automatically have widescreen output.
