Default Re: Mplayer, vpdau, and 3 displays with edge blending.

In this context: the TH2G officially only supports gaps, but while playing around
with the TH2G on USB-register level I figured out how to program an overlapping
region between the middle and the right display. Unfortunately, I couldn't yet figure
out how to create an overlapping region between the left and the middle display.

Nevertheless, it might be possible to do the following setup:

1. The left display is connected to the first output of the video card
2. The middle and the right displays are connected to the second
output of the video card via the TH2G.
3. The overlapping between the left and the middle LCD could be
archived with nvidia twinview metamodes.
4. The overlapping between the middle and the right LCD could be
archived with the TH2G bezel management (non-official blending).

First of all, this would be a highly experimental setup and second,
I didn't yet tried out of the overlapping works as expected in dual
head mode!

Can you please provide me your display resolutions and the number of
pixels you need for overlapping? I could then try out if I could set it up the
way you need it. From the xorg.conf you posted, it seems like you are
using 3x 1024x768 where there is an overlapping of 230 pixel between
the left and the middle display and 234 pixel between the middle and the
right display?

BTW.: thanks for sharing the xorg.conf - I didn't knew it's actually that
easy to create overlapping regions. This way, it should even be
possible to clone an arbitrary numbers of displays, i.e.:

Code:
Section "ServerLayout"
    Identifier     "Layout0"
    Screen      0  "Screen0" 0 0
    Screen      1  "Screen1" RightOf "Screen0"
    Screen      2  "Screen2" Relative "Screen1" 0 0
    Screen      3  "Screen3" Relative "Screen2" 0 0
    InputDevice    "Keyboard0" "CoreKeyboard"
    InputDevice    "Mouse0" "CorePointer"
    Option         "Xinerama"
EndSection
Ah, and BTW.: just out of curiosity, which external hardware are you using
for the intensity blending?
