2 Monitor Tuning: With the buttons in the Move and Size
sections you can tune the position and size of the monitor's
display for the indicated resolution and refresh rate
• Sync Polarity
: If you do not get a satisfactory display with the
default sync polarity setting for the current resolution, you may
try and change the settings.
• Undo: Click this button to undo the last change you made (when
you clicked Apply). If you have made a modification that causes
your screen to go blank or to be unreadable, the keyboard
shortcut for ‘Undo’ is Alt-U.
• Default: Click this button to set the Monitor Tuning to the
manufacturer's default settings.
Note
(1) Use the hardware setting controls on your
monitor, if available, to adjust your display size or
position - instead of the software controls in
'Adjustment - Monitor Tuning.' Check the
documentation of your monitor for information on
your monitor's hardware controls
(2) Resizing the display slightly changes the actual
refresh rate. If you operate a fixed-frequency monitor
check the documentation of your monitor for
information on refresh rate tolerances.
Notes
(1) Press the ESC key on your keyboard to undo the
changes if your monitor has lost synchronization. You may
also use the keyboard shortcut for ‘Undo’ - Alt-U.
(2) If you change the resolution (in Settings) and/or the
refresh rate (in Monitor), you may need to re-adjust the
monitor's display.
