layout. User can use v_shift and scale_up to do the fine tune.
 Use single host to create a 3x3 video wall:
a. Connect host_r0 -> 3x3，and set position layout as 1x9 with position
ID: host_r0, r0c0, r0c1,r0c2,r0c3,r0c4..., r0c8. Complete basic setup.
b. In advance setup, select host_r0. Set screen layout to 1x1.
c. Select all clients. Set screen layout to 3x3.
d. Select r0c3, r0c4, r0c5, set row position to row 1.
e. Select r0c6, r0c7, r0c8, set row position to row 2.
f. Adjust “Tearing Delay Hack” to avoid tearing.
NOTICES:
1. The output video signal timing will always be the same as input video timing.
2. Interlace mode is NOT supported. You will see wrong pictures under
these timing. (1080i, 480i)
3 . N-rows X 1-Cols mode is NOT supported when horizontal resolution > 1280
pixels. Most of applications uses NxN scaling layout and pick one of the
columns to form a Nx1 screen layout. So, this limitation is not a concern in
real world application.
4. 1080P60Hz is preferred video timing which looks better after scaling up.
5. Multi-host video wall can achieve 60fps under 1080P60Hz, so there is no
more concerns Regarding to "scrolling texts".
6. All monitors used in the same video wall are assumed to be the same in
border and dimension. (Bezel and Gap compensation) Manually adjust via
web UI is needed if the dimension is different.
7. Since video wall application typically uses the same monitors without special
HDMI features (3D, multi-channel audio...), Just use a default EDID will be
good to go.
