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
Output
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
Output 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
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. Once your display is accurately showing grayscale and
color, each individual source device can be fine-tuned to match.
Good results can be achieved following the steps in this section. However, more accurate results can be
achieved by using a color analyzer (colorimeter) at the screen to take measurements. If you are not confident
with this process, your dealer or a calibration specialist may be able to calibrate the system for you.
4.6.3.1 DISPLAY VIDEO LEVEL AND COLOR CALIBRATION
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
)
