UltraVista Installation and Operations Manual 25

7. Place displays

Next, use the Edit View in the UltraVista Control program to drag the displays in the same arrangement as

the displays in your video wall. The best way to do this is with the input video source already connected,

so you can verify if the image on the video wall looks correct. Use this step to get a rough impression of

the arrangement of the displays, and to preview where the parts of the input image appear on your screen.

The screens need not be perfectly aligned in this step – you will compute exact coordinates in the next

step.

When you are satisfied with the way the content is displayed on the video wall, go to the next step.

8. Measure coordinates for each display

To obtain the x coordinate for a display, measure the distance of the left edge of the display from the left

edge of the video wall, that is, the left edge of the leftmost display.

For the y coordinate, measure from the top of the topmost display.

Convert the values measured from centimeters to units by multiplying with the density D in units per

centimeter, and adding the x coordinate of the leftmost display (for the x coordinate), or the x coordinate of

the topmost display as offset.

For each display, enter the values for position and size (from step 6) in the Edit window in the UltraVista

Control program.

9. Fine-tune

After you have entered all values for all the displays, you may see some misalignment on your video wall.

This is due to small errors in measurement, and can be corrected by fine-tuning.

To fine-tune, connect a test PC to the UltraVista system as an input source. Create a test image to display

on the video wall. The test image should have two kinds of lines. Straight horizontal and vertical lines help

you fine-tune the size and alignment of displays. Diagonal lines that cross display boundaries help you

fine-tune the distance between displays.

Choose one of the displays as a starting point, and use it as a reference to fine-tune the location of the

other displays one by one.

10. Save

Use the menu item “File . Save” to save your preset.
