So hello , i had this issue for quite some time but i was too lazy to solve it . So my monitor sometimes just closes , black screen for like 5 seconds then back to normal or has some weird lines and pixelated like the old TV
s for 2 seconds , black screen then normal. I have a rx 580 with an HDMI-VGA adaptor because the monitor only has a VGA port. I think it
s the adaptor at fault but i`m not sure . Help
