		example, press the Fn+F4 or Fn+F5 function keys to turn on the external video
		port.
If the image is too dim	•	Try reducing the amount of ambient light shining onto the screen.
	• Press the Picture button one or more times to try different color and
		brightness combinations.
	• Press Settings, go to Picture > Brightness, and increase the brightness.

		quality.

		module to restore full brightness.

or stretched		combinations.

images, smearing, poor quality)	•	Try a different channel or different source. The source could have poor
		picture quality.
	• If the source device has more than one video output, see “Choosing Your
		Video Connections” on page 13.
	• If the problem occurs for the cable input on one or more cable channels,
		press Settings and go to Setup > Channel setup > Cable system. Try the
		different settings, or ask your local cable provider if either HRC or IRC is

	• For an antenna input, try adjusting the antenna.
	• For a source that is connected with a component, composite, or S-video
		cable, be sure you are using a coaxial cable rated at 75 ohms. Any other
		cable or impedance rating can reduce picture quality.
	• For a source connected with a video cable, the cable might need to be
		higher quality, especially if the cable is longer than about 3 m (10 ft). HP
		recommends low-loss cable for longer distances to avoid degrading or
		losing the picture.

		view you like best. If the source device has shape options, try changing them
		too. If you want the picture to fill the screen, the picture might have to be
		stretched or cut off.
