Ok 1st thing
Open regedit and delete the following keys, yes the whole key
- HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers\Configuration
- HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers\Connectivity
- HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers\ScaleFactors
then reboot
This will let windows pick up the monitors fresh, and only once per monitor
If you plug and unplug monitors, you may have to repeat that as windows tends to create monitor entries like they were candy
Now as for B2S
set B2S monitor to the display your playfield is on
in windows, left to right, it has to be playfield(set as primary) backglass, DMD
And all monitor tops must be even
Ok now obviously set playfield resolution appropriately
Now set the Backglass monitor's resolution
next set the Backglass X pos to be playfield +1
So if playfield res is 1920x1080, set the backglass X pos to 1921
OK now for the DMD
1st off, DMD needs to be based on 128x32 as that is the ratio most b2s DMD components are designed around
So, here is what you do
Open MS Paint
resize the blank image to 128 x 32 pixels (you have to uncheck maintain aspect ration)
ok, now click resize again
This time leave maintain aspect ration checked
and change the width to your 3rd screens width
It will auto change the height
THAT is your LED resolution to put into B2S setup
So put that in for LED size
For LED X offset, put in backglass width +1, like you did above for the playfield
Now keep in mind, that is ONLY for a b2s DMD, and it has nothing to do with a VPM or DMD Extensions DMD
Those you just drag where ever you want and size how ever you feel like.
If after plugging and unplugging monitors windows again seems to forget about where the monitors are
just purge the reg keys and reboot, then arrange the monitors quick, and you are ready to go again
Setting B2S to playfield with an offset helps alleviate the issue some.
Cause if you can at least get the playfield right, the rest is simply counting pixels to the right
And no, you do not need to do anything to go play on the laptop by itself
the backglass and DMD will just run XXXX pixels to the right in no man's land
they technically wont know nor care that the monitor is not plugged in
But you will find that you do have to purge the reg entries on a regular basis
so you may with to write a batch file to do it
reg del HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers\Configuration /f
reg del HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers\Connectivity /f
reg del HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers\ScaleFactors /f
shutdown /r /t 10
