Triple Monitor Mount Issues.

[bbail76]

So essentially I am attempting to mount three 27 inch monitors in a corner (its a corner desk). The issue I'm having is deciding if the mount I've chosen will be able to contort to the angles required. 
Starting from the corner, two monitor arms would have to be at right angles to each other along each wall, and the centre mount at 45 degrees. 

The best mount I've found so far is: Mount

Also, in case of any compatibility issues my monitors are:

Centre Screen: MSI Optix 27 Inch Curved Screen
Edge Screens: Kogan 27 Inch Frameless Monitor

I am yet to purchase the Kogan side screens, so if anyone thinks there are better value for money screens which still look aesthetically pleasing (small/no bezels), please let me know! (Note: Kogan Cost $199 AUD)

Many thanks in advance for the help!
