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?
