Video

A display’s native resolution is its width and height measured in number of pixels. Generally, for best performance, an image displayed on this monitor will look best when your computer’s output resolution matches this monitor’s native resolution of 1920x1080.

For computer output resolutions at non-native resolutions, the monitor will scale the video to its panel’s native resolution. This involves stretching or compressing the input image as needed in the X- and Y-dimensions to fit the display’s native resolution. An unavoidable byproduct of the scaling algorithms is a loss of fidelity when the computer’s output video image is scaled by the monitor to fit the display. This loss of fidelity is most apparent when viewing feature-rich images at close distances (for example images containing small-font text).

Your touchmonitor will likely not require video adjustments. However, for analog VGA video, variations in video graphic card outputs may require user adjustments through the OSD to optimize the quality of the touchmonitor’s displayed image. These adjustments are “remembered” by the touchmonitor. Also, to reduce the need for adjustments for different video mode timings, the monitor correctly scales and displays some of the video industry’s most common video timing modes. Refer to the technical specifications for this monitor at http://www.elotouch.com for a list of these Preset Video Modes.

On-Screen Display (OSD)

Four OSD buttons are located on a wired control box. These can be used to adjust various display parameters. The buttons and their functionality are:

Button	Function when OSD is not displayed:	Function when OSD is displayed:
Menu	Display OSD main menu	Return to previous OSD menu
	Display OSD Brightness submenu	Increase value of selected parameter /
		select previous menu item
	Display OSD Contrast submenu	Decrease value of selected parameter /
		select next menu item
Select	Display Video Source submenu	Select parameter for adjustment /
		select submenu to enter

Using the OSD buttons controls an on-screen graphical user interface which displays on top of your input video, allowing intuitive adjustment of the following display parameters:

Parameter		Available Adjustment
Brightness	Increase/decrease monitor brightness.
	Default: maximum
Contrast	Increase/decrease monitor contrast.
	Default: best gray-shade performance
Clock	Allows fine adjustments of the panel’s pixel dot clock.
	Only applicable for VGA input video
Phase	Allows fine adjustments of the panel’s pixel dot clock phase.
	Only applicable for VGA input video
	Automatically adjusts the system clock to the input analog VGA video signal, affecting the
Auto Adjust	H-position, V-position, Clock, and Phase menu items.
	Only applicable for VGA input video
