Here are a few things to check:

1. Which version of Qt and Visual Studio are you using?
2. Once the application is running, are you able to adjust the zoom cursor on the left side of the window?
3. At the bottom of the Window is a status bar where you should see both the haptic and graphic rates. What numbers are you getting?
4. Compile the application in Debug mode and try to place a breakpoint at line 217 of file Application.cpp. Please check if this line is ever called.

I installed Qt 5.5 and I'm using Visual Studio 2013.

I can adjust the zoom cursor, hide settings, and toggle full screen mode.

Graphics Rate is 32 Hz and Haptics rate is 1000 Hz

Line 217 is called when I place a breakpoint there. I believe I feel something there via the haptic device, but just see a black window.

Which version of Windows are you using?
Are you compiling your application in 32- or 64-bit?

Windows 8.1 64-bit system and I'm compiling my application in 64-bit. I didn't change any of the configuration settings and that's what it shows.

A few more things:

• What graphics card model are you using?
• If you run example 08-shaders, do you see a cube with a surface texture?
• Did you install Windows 8.1 yourself or is it a factory installation? If you did a fresh installation, did you explicitly install drivers from the graphic card manufacturer?
• Try compiling the application in 32-bit (just in case!)
• Try compiling the .NET template and let us know if you see any graphics.
• Try running any OpenGL examples that come with Qt 5.5

We will try to test the framework on a system with the same configuration as yours and will keep you updated in the next few days. Let us know if you discover anything new.
