13 Warp Correction

Warp Correction - only applicable if the chosen display type is Projector.

This allows for correction of vertical and horizontal keystone errors caused by misalignment of the projector to the screen. Correction up to +/- 30 degrees vertically and +/-40 degrees horizontally are possible, within the constraints of the chosen native resolution which is dependent on the display device - a higher resolution display device will give better results at more extreme angles of adjustment.

Select the Warp Correction menu item using the OK key, then choose which corner to manipulate, then use the up/down and left/right navi-keys to manipulate the image by changing the angle of adjustment in the vertical and horizontal planes respectively.

Note: Although Vantage-HD's Warp Correction allows for extreme off- angle picture geometry correction and maintains display resolution to the very best possible level even in such situations, Vantage-HD cannot correct for mis-focussing of the projector lens. Depending on the physical and optical characteristics of the optics within your projector, focus errors may occur at extreme projection angles which may cause one side of the image to appear less sharp than the other. After setting warp on Vantage-HD you should adjust the focus of your projector lens to obtain best overall picture sharpness, paying particular attention to sharpness in the center of your screen for viewing movies and TV.

	Gamma	Scroll to Output Gamma Mode and choose the gamma mode you require.
14		This should be left set to Linear unless you also choose the correct input
	Correction	gamma for every input signal you connect. It is used to map an incoming
		gamma curve to a different outgoing gamma curve
		Audio Delay - the audio delay through Vantage-HD is automatically set to
		compensate for the delay through Vantage-HD which is typically 5-7
		fields.
		The Audio Delay option on the Output Menu does not override this
15	Setting Audio	automatic setting but allows fine calibration of the audio delay in steps of
	Delay Mode	approximately 1 mS, to advance or retard the audio so as to compensate
		for further delays in your display device or your audio system. If you notice
		lipsync errors when viewing program material, you can use this option to
		reduce or remove that error. Fine tuning of the audio delay can only be set
		correctly when viewing real program material so should not be adjusted at
		this stage

Output configuration is now complete, apart from fine-tuning the audio delay, which may require adjustment later, depending on your display device and audio system. Exit the Output Menu by pressing the left navi-key.
