ADJUSTING PITCH AND PHASE
Some computers and video cards may not allow the auto-sync function to fully work when the DTF-521
is first connected. If some portion of text appears blurred, adjust pitch and phase by following the
procedure below. For crisp images, set the resolution of your video card to 1024 x 768.
• In the Pen Tablet control panel,
select the C
ALIBRATE tab.
• If you are working with multiple
displays, be sure the display
corresponding to the DTF-521 is
selected in the M
ONITOR menu.
• Click on the C
ALIBRATE... button to
activate the calibration screen.
• Using the OSD controls, open the
OSD menu and select the P
ITCH
icon. Then adjust the pitch level so
that the pattern of fine vertical
stripes displays evenly. (For details
on changing the OSD settings, see
On Screen Display (OSD) settings
on page 27.)
• In the OSD menu, select the P
HASE
icon. Adjust the phase level so that
the adjustment pattern shows
clearly.
• After completing these adjustments,
press the E
NTER and MENU buttons
to exit the OSD menu.
Click on the C
ANCEL button or press
ESC to exit the calibration screen.
