4.6.2 OUTPUT 50HZ OR 60HZ AUTOMATICALLY
If your display supports 50Hz input and can produce real 50Hz refresh rate video image*, it is
better to configure Crystalio II to output 50Hz resolution when source video is 50Hz (i.e. PAL
signal); and output 60Hz resolution when the source video is 60Hz (i.e. NTSC signal). This is
because the output video will be perfectly smooth if the refresh rate of video image displayed is
the same as that of the video source. Otherwise, you will see slight jerkiness of subject
movement, especially when there are camera pans.
* Some displays that support 50Hz input will convert the 50Hz video back to the display’s native 60Hz (the majority of pixel-based
displays have a native 60Hz vertical refresh rate) and produce a 60Hz refresh rate video image. You can verify this if you have
configured Crystalio II to output the same refresh rate as the input; if with a 50Hz source you see jerkiness in the image, your
display’s internal scaler may be performing a frame rate conversion to 60Hz
To configure Crystalio II to output 50Hz resolution when input refresh rate is 50Hz, and output
60Hz resolution when input refresh rate is 60Hz, follow the steps below:
• Press the Menu remote control key to enter the OSD (On Screen Display) menu
• Select System then DynamicVP TM (if you can’t see the DynamicVP TM option, select the
Advanced Option under System sub-menu and turn Advanced Option ON first)
• Turn the DynamicVP Mode ON
• In the first line of rules under When Input, select 50Hz
• In the first line of rules under Action/Resolution, select Fixed Resolution
• In the dropdown list of resolutions, select your display’s native resolution; then in the
dropdown list of refresh rates, select 50Hz
• In the second line of rules under When Input, select 60Hz
• In the second line of rules under Action/Resolution, select Fixed Resolution
• In the dropdown list of resolutions, select your display’s native resolution; then in the
dropdown list of refresh rates, select 60Hz
• Press the Menu remote control key to exit the OSD menu
4.6.3 BASIC CALIBRATIONS
4.6.3.1 CALIBRATE THE VIDEO LEVEL AND COLOR BALANCE OF YOUR
DISPLAY/PROJECTOR
Crystalio II has been designed and built to output broadcast standard video. You can even use
Crystalio II as a reference video signal generator. You should therefore make use of the internal
video test patterns to calibrate the video output level and color balance of your display.
Step 1: Reset Crystalio II’s video settings to the default values, which include:
• Contrast, Brightness (default = 0)
• Red, Green, Blue Offsets and Gains (default = 0)
• Gamma correction (default type Standard, and value = 0)
Step 2: Select a correct output video level from Crystalio II’s HDMI output port:
• Press the Menu remote control key to enter the OSD (On Screen Display) menu
• Select Output then Output Port Configuration. You should see output configuration
options of HDMI output ports (If not, select the Advanced Option under System sub-menu
and turn Advanced Option ON first)
• If your display is expecting video from a video source with HDMI output, configure
Crystalio II’s HDMI output level as HDMI Standard
• If your display is expecting video from a normal consumer AV product, configure
Crystalio II’s HDMI output level as Video Level (16-235)
• If your display is expecting video from a PC, configure Crystalio II’s HDMI output level as
PC Level (0-255)
