Image Controls

LEFT / RIGHT
Controls Horizontal Image Position within the display area of the LCD.
DOWN / UP
Controls Vertical Image Position within the display area of the LCD.
H.SIZE (V.SIZE) (Analog input only)
Adjusts the horizontal size by increasing or decreasing this setting.
If the "AUTO Adjust function" do not give you a satisfactory picture setting, a further tuning can be performed using
the "H.Size (or V.Size)" function (dot clock). For this a Moiré test pattern could be used. This function may alter the
width of the picture. Use Left/Right Menu to center the image on the screen. If the H.Size (or V.Size) is wrongly
calibrated, the result would look like the left drawing. The image should be homogeneous.
FINE (Analog input only)
Improves focus, clarity and image stability by increasing or decreasing this setting.
If the "Auto Adjust function" and the "H.Size" function do not give you a satisfactory picture setting, a fine tuning can
be performed using the "Fine" function.
For this a Moiré test pattern could be used. If the Fine value is wrongly calibrated, the result would look like the left
drawing. The image should be homogeneous.
