3.4 Spreading One Picture Over a Wall
58
3.4.2 Zoom and Position
Position moves the picture on the screen. This is NOT the same as optical engine alignment. Zoom
adjusts the edges of the picture to make it fit with the other pictures in a wall.
Position
Press the
MISC button once to open the Picture
Position menu. The four arrow keys move the picture
on the screen.
The numbers for Horizontal and Vertical Position
refer to the number of pixels from sync to the first
displayed pixel. These numbers get smaller as the
picture moves up and to the left.
Black edge
If you see a black edge on the screen, and you can’t
move the picture to cover the black, you must adjust
the optical engine position. See “Adjusting Margay’s
Engine: Important Step” on page 38 to do this.
Zoom
Zooming is used mainly to make the edges of a
large picture—one that covers many Margay
screens—fit each other side-to-side and top to bot-
tom.
Zoom menu entries
• Image Resolution is the resolution of the source
picture.
• This Cube is the number of pixels this unit is
using of all the incoming pixels, followed by the
size of the wall (from the Wall & Aspect Ratio
menu) and the Column and Row of this unit.
Using Zoom and Position
Picture Position is usually used to center the pic-
ture on the screen.
If the screen has a black edge on one or two sides, and
you try to move the picture to cover the black side, and
this does NOT cover it, see “Adjusting Margay’s
Engine: Important Step” on page 38 for help.
Zoom is primarily used to adjust the edges of the pic-
ture when one picture is spread over several cubes.
Whether you use Clarity’s Big Picture™ or an exter-
nal video processor to make one picture cover several
cubes, the Zoom controls can make the edges fit
together.
