While launching Genymotion emulator you may witness this error. This error sometimes do not go even after updating display drivers.
"Unable to start the Genymotion virtual device.
Check if your video card supports OpenGL. If no, then Genymotion virtual device can not start. If yes, maybe you should update your video card drivers.
Detailed information: Failed to initialize backend EGL display (error: 4)
If needed, update your video card drivers."
This happens when you try to launch emulator on remote machine using mstsc. The machine need to have monitor connected. Try to launch emulator directly on the machine and it will run.
You can use teamviewer instead of mstsc to connect to remote machine and turn the emulator on.
