Davinci resolve crashes when selecting dual monitor display

Hi,

Just build a new PC and Davinci Resolve (both 12.5 and all the 14 beta versions) crashes whenever I try to setup dual monitor display. My guess is that this crash is related to my graphics card (GTX 1080 ti).

This is my setup:

i7-6850k
Asus rampage V edition 10
64 gb ram
GTX 1080 ti (with latest firmware)
Two Asus monitors connected via HDMI (same model both).
Windows 10 Pro
Samsung 960 PRO NVMe M.2 512GB

Thanks in advance.
