Normal orientation

In this example we have two screen in landscape with application PC running Windows using AMD Eyefinity graphics card. We want to configure the screens for running Cornerstone applications as well as third party applications using TUIO.

For TUIO stream to be available, you need to have MTServer.exe or any other Cornerstone program running.

Two screens in landscape normal orientation

Configuration steps

1. Create Eyefinity Display Group using the graphics cards drivers.
   
2. Adjust bezel compensation
   
3. Right click on desktop, select "Screen resolution" and calculate bezel from the resolution. In the image below, horizontal resolution is 3888 = 1920*2 + 48, i.e., bezel is 48 pizels.
   

4. Adjust config.txt and screen.xml to take the bezel into account.

Flipped orientation

This is the same as normal orientation except that the image is flipped vertially.

Two screens in landscape normal orientation

Configuration steps

1. Right click on desktop, select "Screen resolution" and flip both screens.
   
2. Adjust bezel compensation
   
3. Right click on desktop, select "Screen resolution" and calculate bezel from the resolution. In the image below, horizontal resolution is 3888 = 1920*2 + 48, i.e., bezel is 48 pizels.
   
4. Adjust config.txt and screen.xml to take the bezel into account.
   • screen.xml with 48 pixel bezel is the same as in normal orientation
   • config.txt with 48 pixel bezel

     TUIOSender {
         features = "fingers objects"
