Texas Instruments MATRIX 3000, DW30 user manual 3. Regions and Video Standards Summary

Section 3: Operation

VIDEO STANDARD: For all but the more unusual video standards available in the world, the projector automatically detects the incoming horizontal and vertical frequencies and sets the projector’s processing of this signal to the corresponding standard. The current video standard name appears in the Video Options submenu, and

includes an “A” if it has been auto-detected. Press to view or select a different video standard from those available to the

projector—any that are disabled have frequency characteristics that differ from those of the incoming signal. Selecting a specific

standard forces the projector to process the signal according to this standard.

NOTE: Best results are obtained with defined channels. Otherwise, switching from one video source to another can sometimes cause slight disturbances in the display, indicating that the Auto function is struggling. Recover by briefly selecting a different video standard, then going back

Table 3.3. Regions and Video Standards: Summary

Standard	Where Used (SUBJECT-TO-CHANGE)
NTSC	N. America and Japan
NTSC 4.43	A tape-only standard for partially-translated hybrid signals
PAL	Most of Europe, China, Australia, some of S. America, some of Africa
PAL-M	Brazil
PAL-NC	Argentina, Chile, other Latin American countries
PAL 60
SECAM	France, Eastern Europe, most of Africa

NOTE: Generally, use “Auto” for all instances EXCEPT: 1) a poor quality input signal or 2) a black-and-white video signal. In order to detect and display such signals, select the relevant standard from the list.

INPUT VIDEO BLACK — This control compensates for incoming elevated black

levels present in certain video signals, and ensures that blacks in the display are

neither crushed (i.e., where dark grays appear black) nor excessively elevated (i.e., where blacks appear dark gray). By default, the projector automatically determines the best setting according to the type of incoming video signal:

•0 IRE – Used for DVD output with “enhanced black”, SECAM, most PAL standards, and Japanese NTSC.

•7.5 IRE – Used for most NTSC video signals.

For some types of video, you can override the setting. The control is disabled for other types of video (and all graphics sources). Generally, if black appears crushed when brightness = 50, choose “0 IRE”. If black appears excessively elevated, use “7.5 IRE”.

	COLOR — This slidebar adjusts the color saturation level, i.e. the amount of color in a
	video image. Lower settings produce less saturated colors — for example a setting of
	“0” produces a black and white image. If the color level is too high, colors will be
	overpowering and unrealistic.
	TINT — This slidebar adjusts the red/green color hue for true color reproduction of
	video signals connected to Input 3 or 4. For best results, adjust tint while displaying an
	external color bars test pattern—otherwise, it is recommended that tint remain at its
	default setting.
