B. The display only supports 50 Hz input. This is the opposite of case A, and the required
conguration is also the opposite - i.e., the output frame rate for 60 Hz source should
be set to 50 Hz unlocked, and the rate for 50 Hz sources can be set to either 1:1 locked
or unlocked at 50 Hz (for all the same reasons noted in the rst example).
C. The display supports a wide range of frame rates (e.g., a CRT projector). In this case
you can congure things most any way you like. If motion judder with 3:2 pulldown
bothers you, then use the iScan’s 48 Hz or 72 Hz source-locked output options for lm-
based 480i sources. If not, then 60 Hz locked is a good choice. For 50 Hz sources, unless
you notice display icker at 50 Hz, you’d probably want to run at 50 Hz locked to avoid
repeated/dropped frames.
D. A digital display supports a narrow range of frame rates, either around 50 Hz or
72/75 Hz. If the display supports both 50 Hz and 48 Hz, and the primary use of 60 Hz
source is lm-based material, then you would likely want to congure the iScan as 48
Hz source-locked for 60 Hz sources, and 50 Hz locked (or unlocked, if desired) for 50
Hz sources. If the higher frame rate (72/75) is desired or required, then both source
types can be congured for the 3:3 source-locked output option. For non-lm material
you may nd that there’s too much motion stutter, although that tends to be a very
personal thing as not everyone perceives this the same way (as with low frame rate
display icker).
Border Level
The border level setting is global, that is, there is only one border level setting for the system.
To adjust the border level, push the p or q button. The current level is shown. The default value is
‘0’. Push the p or q button to decrease or increase the border level.
Gamma Correction
The default gamma curve on the iScan VP50’s output is Linear (1.0). This should be left set to Linear
unless you choose the correct output gamma curve for the connected display. The range is 0.5 to
2.5.
HDCP Mode
There are two HDCP modes:
•
Off: HDCP is disabled at the iScan VP50’s HDMI output.
• On: The iScan VP50 continuously looks for a HDCP display device on its HDMI output.
NOTE: The iScan VP50 is not designed to remove HDCP from a protected signal. If this setting is set
to ‘On’ make sure that the corresponding HDCP Mode setting on the input is also set to ‘On’.
DisplayProles
A display prole is a group of display parameters you can save and easily recall in the future. A display
prole consists of a set of display parameter selected from the Output Setup menu.
This includes the following:
• Output Type (Analog or Digital)
• Format (Resolution and all video output timing information)
• Output Aspect Ratio
• Sync Type
• Color Space (YPbPr/YCbCr or RGB)
• Output Level (Video or PC)
