Video Wall setup procedure
For every Video Wall setup, just only three key points as below need to be clarified.
Monitor size detail, including monitor outside width (OW) and outside height (OH),
inner viewable
Width (VW) and viewable height (VH), this is for the Gap Compensation function. The
OW, OH, VW,
VH is a number or value with the unit based on every 0.1mm. For example, if the
outside width is
56.5cm, then 56.5cm = 565mm = 5650 unit.
Video Wall size, such as matrix 1x1, 2x2, 3x3, 4x4…etc, or even the rectangle 1x2,
1x3, 2x3, 2x4, 3x2,
3x4,…etc.

Monitor Position, each monitor has its own row number and column number which
represent its “Monitor Position” in its belonging Video Wall Group. Besides, these row
and column number are started from 0, users can refer to below examples:
Example 1, 2 X 2 Video Wall setting, please follow below setting
procedures:
Here we use monitor, Acer P246HL, as our model type.
1. Open the IE of the controlling PC. If the link is well, you will find the starting
Page as below

2. Double click any of the RX, then you can find the below chart, then click
“Video Wall Setup”
3. Mark the “Show OSD” on the bottom, then you can see the OSD number
showed on each display monitor, please be noted the OSD number is
generated at random, not in order.

4. After then, we have to do the video wall setting one by one. There are four
monitors in a 2x2 video wall group, which are the upper‐left, upper‐right, lower
left and the lower right, user can find below structure chart:
5. We first set the upper‐left monitor: Measure the Monitor outside width (OW)
and outside height (OH), inner viewable width (VW) and viewable height (VH),
here we use monitor, model: Acer P246HL as example, the OW and OH of
P246HL are 56.5cm and 33.5cm, VW and VH of P246HL are 53.5cm and
30.0cm, then we can have the below detail:

OW: 5
