Extended desktop coding

#1 · December 31, 2025, 10:23 pm

I want to create an extended desktop app that will auto detect the size of the 'main' pc screen and the extended screen size.

Is this possible?

I want the main pc to have an option to choose an mp4 or image from the users pc and then play/show it on the extended desktop at the 'correct' resolution.

Thanks everyone :)

Look under the freebies section. There is a plugin developer named EMO who has a couple of monitor plugins. Maybe they could be of help to you.

Thank you.

Installed the dual monitor plugin from EMO but it looks like it just detects montors.

I am looking for something that will run on the main monitor and then another 'screen' run on the other one - like an extended drag option.

Not sure if there is any plugin that can do that

VisualNeo Win can run more than 1 instance of a publication exe... Perhaps you can detect in the first publication exe, if another one is launched and then position it on the other monitor...

I have Brad's ezAutomation plugin... Maybe something in there that could be of use to you. It's a paid plugin, but well worth the money...

Hope that helps...

Hi thanks,
Can't seem to find a solution.
All i want to do is have a screen on my pc that sends actions to an extended desktop display>

So, for example - if i had a button on my screen that, when pressed, performed an action on the desktop display.

Need help trying to do this :(
Trouble is, there are a few venues that i go to and they have different screens with various resolutions and it might mess the extended display up!

Here is how far i have got.

On my main pc screen i have a container (GameWindow) which is 1920 x 1080.
I also have a button called Launch Window.
[code in button is-
MoveObject "GameWindow" "0" "0"

When i click the LAUNCH WINDOW button it displays the GameWindow as a smaller version with a taskbar on my screen.
If i grab the task bar and drag it over to my extended desktop and then click a button, called FULL SCREEN, that is inside the container, it goes full screen.
[code in button within the container is-
SetVar "[X]" "[WindowLeft]"
SetVar "[Y]" "[WindowTop]"
CloseWindow "Game Display"
CustomWindow "Game Display" "[X]" "[Y]" "GameWindow" "NoBorder+AlwaysOnTop+ResizeToFit"

trouble is i cant see the main page screen on my pc .... all i see is the extended display on the extended desktop and nothing on my screen :(

I want to place buttons on my pc display screen that creates actions on my screen and the display screen as well

Can anyone advise a solution?

Here's howw I would do it. Create two apps and connect them with hpwRemote - VisualNEO. Cross-platform App Development Tool for Windows

the remote app in one screen window will then send "play" commands directly to the app in the other screen window...

(The hpwRemote pugin lets these two apps share the same variables, etc. Each app can set different screen resolutions when they load...)

here is a free app. QRes provides automatic screen mode change for Windows applications. For instance, you can make QRes switch to 800 x 600 @ 256 colors as long as you run a game and switch back to your regular screen mode when it is over.
