I ran the driver update which you posted last night, and did not fix the issue. For the record, and maybe to assist/cross reference solutions, I've found another thread which sounds to be a very similar issue other users are having:
Regarding the HD530 video flickering issue. I can create it and eliminate it at will now that I know exactly what is causing the issue. As for why it happens that is for Intel to figure out.
It turns out to be the DDR4 memory speed. The issue will begin intermittently at 2600MHz and gets progressively worse as I increase the speed. At the maximum speed for my kit 3466MHz the screen just vibrates wildly.
I solved it permanently by installing a nvidia GTX 750 graphics card and disabling the HD530 in the BIOS. Now I have triple the video speed and no more flicker issue. On a personal note I do feel cheated by Intel as was I expecting the video to work properly and did not want, or should have had to spend an extra $139 to solve Intel's video issue.
Thanks for the information. I am sure Intel is working hard to get this flickering issue solved as soon as possible.
