Thank you for contacting the Intel Communities.
I would like to know, have you tested the system using different cables?
-When did the issue started?
-Was it present in previous uses of the VGA port to get an external display?
-Is this happening with another computer that also uses the VGA port? (using the tested monitors with your computer).
-Have you tested the system with the default drivers from Windows 10*? **
-Have you tried using different resolutions from the graphics control panel?
**You can get the default drivers after uninstalling the current drivers from the device manager.
Different things could be causing this issue: drivers, the port, the cable, the monitor, hope these questions help us to find out what could be the possible source of the issue.
I look forward to your reply.
I have the exact same problem as reported by LucasFox.
My laptop is a Lenovo Z50-70 i5-4210U running Windows 8.1 64-bit.
To answer the questions you asked:
- I have had this issue ever since I bought the laptop
- I don't know what you mean, but I experienced this problem with different monitors and different cables, so I'm pretty sure it's a problem with the port itself (or its drivers)
- No (but I'm pretty sure I never updated the drivers in the first place)
- No (I stick to 1920x1080)
My driver is version 10.18.14.4264 from 4-8-2015.
Any suggestions would be highly appreciated. Thanks!
Have you tested this with the drivers from Lenovo?
Generic drivers from Intel: Download Intel® Graphics Driver for Windows 7*/8.1* [15.36]
NOTE: While using OEM systems like yours, the recommendation is to download and install the drivers from your computer's manufacturer website.
This is to avoid losing any special features or settings while using the generic drivers from Intel®.
Another step to test would be to start your system in safe mode, by doing this, default drivers are going to be loaded, if you get the issue with that, we could that the issue is the port.

thank you for your answer. In the meantime, I have tried the solution as has been described here:
And the situation seems to have improved a lot so far. I see a lot less flickering and blinking (nearly none at all anymore) so I'm happy.
