Matrox, and window size?

[Marsat]

Hello everyone!

I recently buy a Matrox Digital ME splitter, and i’m trying to use it with two screen… But, the window do not want to take the rigth heigth and width… even with “windowResized”.

I want my window App 1360*2 x 768px… And it is not working if i want more, it just keep the size of one screen (and i don’t use ofGetWidth…).

Does anyone had the same problem?

Hey, sorry for some obvious questions here:
Did you check out the display settings options? are the screens connected? what does you panel look like ? what windows? or linux?
There must be a way to do it…

this is very old but it might help:

dual screen windows

Hi So to do dual screen on windows (1024x768) i open my app 2048 x 768 in Window mode and set the window position to 0,0 Is this the best way to do it? I auto hide the windows tool bar at the bottom so it fills the screen. However if you press the start menu or switch to the desktop whilst the software is running, windows resizes your app window slightly so that the windows toolbar shows, and then it doesn’t make the window back to the full size. Has anyone else experienced this? Thanks

No, thank you for this question, i was a little bit fast.

I’m working on Xcode on OSX (maverick, not windows, but i will look at your link), and i have two televisions screen, who are perfectly connected to the matrox display, and i use the matrox software to have a 1360*2 x 768px resolution.

When i click on the resize button, it works perfectly, but i want to have it in a fullscreen mode

Can you help me about it?

how does your main.cpp look like?
maybe this post will help you better:

Fullscreen dual screen

one quick note on the code above, you’ll need to force xcode to compile the .cpp files as objective-c++ if you want to mix objective c code in your .cpp file. you can do this in the sidebar: [image] and this at the top of your h file: #include <Cocoa/Cocoa.h> #include <Carbon/Carbon.h> hope this helps, zach

sorry, what is the [image] sidebar ?

here is my main.cpp

#include “ofMain.h”
#include “ofApp.h”

//========================================================================
int main( ){
    //ofSetupOpenGL(1360, 768,OF_WINDOW);            // <-------- setup the GL context
    
    ofSetupOpenGL(1360*2, 768, OF_FULLSREEN);
    ofSetWindowPosition(ofGetWidth(), 0);

// this kicks off the running of my app
    // can be OF_WINDOW or OF_FULLSCREEN
    // pass in width and height too:
    ofRunApp(new ofApp());

}

try this in main.cpp

#include "ofMain.h"
#include "ofApp.h"
int main( ){
	ofSetupOpenGL(1024,768,OF_FULLSCREEN);
	ofRunApp(new ofApp());
}

and this in the ofApp.h:

void ofApp::setup(){
	ofSetWindowPosition(0, 0);
	ofSetWindowShape(ofGetScreenWidth()*2, ofGetScreenHeight());
}

Let us know what is the result please.

Probably something like that would work :

In main.cpp:

#include "ofMain.h"
#include "testApp.h"

#include "ofAppGLFWWindow.h"

int main(){
 ofAppGLFWWindow window; 
 window.setMultiDisplayFullscreen(true);
 ofSetupOpenGL(&window,  1360*2, 768, OF_FULLSCREEN);
 ofRunApp(new testApp());
}

[Jordi]

yes that must do too. Both codes work well on my computer.

… hmm… simply…
… i restarted my computer, and it’s working fine now… (i’m laugthing, that was really stupid, my apologize ^^")
