H.SIZE or Horizontal Size adjustment control: 
This is the monitor’s width size adjustment, you need to center the 
screen horizontally first before making this adjustment. Sometimes 
increasing the Horizontal size to the limits may cause the monitor to 
behave abnormal or the screen may become shaky. Normally leave about 1/8 of inch of blank 
border on each side of the screen, for the best result. This is needed for the proper monitor 
timing adjustment.
H. Center or Horizontal Center Control:
This moves the screen to the right and left. 
HEIGHT or Vertical size adjustment control:
This is your vertical height adjustment. You need to center the screen 
vertically first to get this correct. In some cases the video card will show 
a bigger size for 640x480 and 1280x1024 resolutions than the 
1024x768. In this case if you want to be able to see most resolutions completely, adjust the 
monitor for 1280x1024, so that 640x480 will fill up the screen too.
V-CENT or Vertical center adjustment control:
This control will move the screen up or down (vertical center). In some 
cases the  video card will show a bigger size for 640x480 and 
1280x1024 resolutions than the 1024x768. In this case if you want to be 
able to see most resolutions completely, adjust the monitor for 1280x1024, so that 640x480 
will fill up the screen too.
SPCC (Side Pin  Control) or Screen geometry balance control:
Do not touch this control, unless the screen is not straight from the 
sides.
