Essentially, both my monitors will sometime flick off and then back on a second later. They seem to do this at the same time and it is usually due to my fridge starting to cool again (at least, it
coincides with a click sound from the fridge). The fridge and the screen are not connected to the same power strip and are plugged (indirectly) into different wall sockets. Additionally, if I knock one of the HDMI cables (without disconnecting it), the corresponding monitor will also flick off and on again a second later. One connection is DVI - DVI and the other is DP - HDMI female connected to HDMI male - HDMI male.
This problem has been present for a long while (probably since I bought the computer). It only happens infrequently (possibly around once every half hour for a second) and irregularly (appears to be tied to fridge cooling end). However, it can still be very frustrating if the screen goes black at a crucial moment.
I have had the same issue:
- in three different rooms - the same fridge was present in all of them.
- with different operating systems (previously Windows 7, now Windows 10).
- with different graphics driver (previously outdated, now all up to date).
- when using only one screen at a time (problem has happened with each).
I am not sure if the issue is related to the screens themselves, the power supply or the graphics card (possibly something else).
