Question VGA Sync Issues

[CaptainTologist]

A friend of mine got an old PC (Windows 8) from an acquaintance, who did not need/use it any more. When he plugged it in using VGA, the screen showed a weird pattern. If I had to guess, with limited knowledge on the format, I'd say that somehow the hsync and vsync signals are mucked up. What could be the cause of this?

does this pattern show up in BIOS as well?

Maybe the refresh rate and resolution is too high for this monitor
is the cable plugged in tightly?
try a different cable

He just confirmed it's a monitor issue, but thank you.
