how do i install the new intel graphics driver

So, I am trying to install the Intel Linux Graphics Installer but I'm having issues as it does not install on my system. However the standard intel driver does not support the 3D features of this GPU. I upgraded to a new motherboard with an onboard graphics chip.

I have a CentOS6.5 system with the latest yum updates running. And just so we can be clear, I came from a 2015 MacBook Pro 13' Retina that also caused similar issues with the 4K Dell.I need some help to install the latest intel video driver. Hoped this update would fix it, but alas not. And even without the 2K one hooked up, when I awake the SP4, the 4K monitor stays blanked out until I do a mix of mouse wiggling within it's workspace and pressing the monitor control buttons. When I connect the 2K monitor the 4K one keeps blanking out. I have a Surface Pro 4 (i7 256GB SSD 16GB RAM) which from a design and operation angle is outstanding, but it (or Intel) is/are having trouble driving my Dell 4K + Dell 1080P ('2K') monitors together via the new (and well designed) Surface Dock.
