Hi everyone,
I have bought a second screen that I wanted to connect with my laptop by using the HDMI port. Even though the second screen does connect, it keeps flickering on and off and sometimes it even provides the notion "input not supported". As I read on the internet, there is possible a problem with the HDMI/video card driver. However, I cannot seem to fix the problem.
I was hoping someone could help me on this forum!
Thanks in advance!
** Update
After trying various solutions agains, uninstalling/installing/updating all video card drivers, along with synchronizing the refresh rates of both monitors to 60 hz, apparently solved the problems I had. The screen hasn't flickered anymore since.
