Monitor Display

[Bob]

Our current game has 3 monitors. they are numbered as follows in Windows 10 display and Nvidea:

1)  main backglass

2)  DMD

3 ) Used to fire up windows and then monitor switches etc... during game play.

 When playing the game you don't even see monitor 3 as its on the back of the cab.

We now want to make that monitor little more accessible without being a distraction to game ply so i downloaded an app called spacedesk that allows you to set up any monitor as wireless via wi-fi.  I got it working perfectly in Windows using my IPad as the wireless monitor and emulating monitor 3. Windows shows it as a 4th monitor doing this.

However, when I activate MPF, the game starts but there is no game displays (only the desk top) on monitors 2 & 3. The game is running though as the sounds are there.

 

One other point is that that NVIDE is not showing the 4th monitor at all and can't find it when I search. I thought this was a windows issues but it works well until I activate MPF. I checked and its not changing the number of the monitor.

Any ideas?

ok I got this working. Instead of emulating a screen i just created a new one

Ok just to pick up on the above. Now I have a different problem.

Instead of going with a wireless display we decided to go with a 7" monitor that we could leave inside the coin door.

Our current game has 3 monitors, all connected via HDMI to a 4 port graphics card and everything is working fine. The monitors are numbered as follows in Windows 10 display and Nvidea:

Monitor 1)  Identified as the main monitor, its a 21" connected by HDMI. Currently at the back of the machine, we only use this for diagnostics and to initially pick a shortcut for whatever game we want to run

Monitor 2)  Backglass (24")

Monitor 3 ) DMD (24")

Monitors 2 and 3 simply act as regular extended monitors in windows until mpf is run in monitor 1

So everything was fine until I switched out the 21" monitor 1 for a 7".

The game is running (i can here the sounds and monitor 1 has the box open running the progam but nothing is displayed on the other 2 monitors.

I tried rearranging the monitors in display settings and I can get some partial display.

Should a simple monitor swap cause all this ?

Did you update your displays in config file? You might have your coordinates all off now. Also, did position of monitors relative to each other in Windows stay in same orientation? Left to right, top to bottom, etc.

No, I made no changes to the displays in my config file.

Yes, the position of the monitors relative to each other in windows is the same.

 

Why would I have to make changes to the config file? Both monitors are the same resolution and in landscape mode. Just a physically different size.

I wouldn’t think that would matter

If same resolution you should be good. But resolution or orientation would change the overall coordinates of downstream monitors.

actually, this monitor is not even described in the game code. its only used as a windows monitor to activate the game

Actually I forgot that I had offset my displays to allow for the 3rd monitor.

And... the old 3rd monitor was 1920x3840 where the new one is 1024x600 so I think i have to revise that "1920" in my code below to "600".

Does that make sense?

[Avery Tummons]

I would say swap to 1024. Going from old worth to new width. Assuming they’re all setup the same in operating system so you only need to offset to the right and bottom of all displays is still in line.
