Hello, i have the same problem with my Gigabyte Brace N3150. After a lot of searching i found out that this also is related to HDMI (maybe other digital output as well, but i can't test that).
I've a HDMI and DSUB VGA and tried the VGA and saw that the problem does not occur with VGA. But of course i don't want to use VGA but HDMI.
I hope this helps.
