You have been subscribed to a public bug:
External screen flickers on and off (image is present and then signal is lost,
flickering is random, but very often, ~3 times in 10 seconds) on a fresh
installation.
Details:
- I'm using a laptop (ASUS GL552VW) with external monitor connected via HDMI.
The HDMI port is connected to my iGPU, Intel HD 530 (there is no way to make
that HDMI work with NVIDIA GTX 960M in my laptop).
- Nothing was installed after installing the OS - i connected to the Internet
while installing the system and marked the option to download the updates.
- I had that issue on Windows 10 - I fixed it by installing a latest Intel GPU
driver from laptop manufacturer's (ASUS) site, uninstalling drivers installed
by Windows - they were the latest Intel drivers.
- Internal screen works fine.
- If I mirror external and internal monitor, external isn't flickering, but
internal monitor's resolution is lower that external's one.
