Signal Type: Select Signal Type from the Options menu to specify the incoming signal type
(encoding method):
• Choose Auto to have the Vision 85 automatically detect the signal type.
• Choose RGB (1) for RGB-encoded video signals.
• Choose YCrCb4:4:4 (2) for uncompressed, component video. This encoding method uses a
“luminance” signal (Y) to represent brightness and “difference” signals (Cb and Cr) to
represent colors.
• Choose YCrCb4:2:2 (3) for compressed, component video (similar to YCrCb4:4:4).
In most situations, selecting Auto produces the most accurate colors. If it does not, try the
other choices and select the one that does.
Color Space: “Color Space” determines how the color components of an analog input signal
are decoded for accurate color in the display. Select
Color Space from the Options menu to
specify the color space to use. In most situations, selecting Auto produces the most accurate
colors. If it does not, try the other choices and select the one that does.
HDMI Black Level: This control compensates for incoming elevated black levels present in
certain video signals. When you set it to Auto, the Vision 85 automatically determines the
best setting according to the incoming video signal type. For some types of video, you may
want to override the setting. Set it to 0 IRE if blacks appear elevated (dark gray). If blacks
appear “crushed” (too dark), set it to 7 IRE.
Background: Select Background from the Options menu, then press or to select the
image background – solid blue, solid black or the Vidikron logo welcome screen. The
Background appears when no incoming signal is present.
Power Save: Select Power Save from the Options menu to access the power management
features of the Vision 85.
• RS-232C Port: When this option is set to On, the RS-232 port is always active and using
power, even when the projector is in standby mode. When set to Off, the RS-232 port is
inactive and does not consume power when the projector is in standby mode.
• Auto Power Off: When this option is set to On, the projector enters standby mode after
15 minutes of inactivity (no input signal). Five minutes before this is to occur, the message
“Enter STANDBY mode in 5 min.” appears on-screen. This message updates to indicate the
amount of time before the projector enters standby mode.
When set to Off, the projector remains in the “power on” state regardless of the presence
or absence of an input signal.
Baud Rate: Select Baud Rate from the Options menu, then press the or button to
change the data rate of the RS-232 connection between the projector and the VHD
Controller. The default setting is 9600 bps. Do not change it unless specifically instructed
to do so by Vidikron Technical Support.
Always set this option to On. Doing otherwise may disrupt
communication between the projector and VHD Controller.
When you set the Auto Power Off function to Off, the LED function (refer to
4-57) is automatically set to On.
