Also have a Sony Vaio Pro 13.3 with Intel Core i7-4500u. I get the same fuzzy noise TV screen pattern on my laptop display, however if I plug-in a monitor via HDMI or my Lenovo USB 3.0 dock there is no issue on that monitor. I had issue both before installing the USB 3.0 dock display drivers as well as after installing them.
I have reverted back to the 8.0 64-bit driver for now with the following issues:
- IE 11 some websites have giant X's thru their images
- None of the Intel configuration programs launch
- Cannot get StarCraft 2 to launch (haven't tested other games)
