The 4770k is a 4th Generation Intel® Core™ Processor with Intel HD Graphics 4600. Did you install the Intel Graphics Driver from Intel. I think you might be using a generic microsoft driver.
Try the driver from Intel: Intel® Graphics Driver for Windows® 7/8.1/10* [15.40]
It should work great with that processor. I have my Roon Server on a Hackintosh that has a Core i5 2500k 2nd Generation Intel® Core™ Processor with Intel HD Graphics 3000 and it works fine.
Edit: My apologies, I overlooked the OS version: Windows Server 2012 v2.
