Vidikron Model 85 User Manual

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. 

When you set the Auto Power Off function to Off, the LED function (refer to 
page 69) is automatically set to On.
