Is there a better way to draw non 45deg angle line, e.g., on VGA symbol?

[melkord]

I am drawing VGA symbol.
if I use non 45deg angle, it looks better but the arrow looks bad.
I am aware that I am a little bit nitpicky here. lol.

Other suggestions for VGA symbol are also welcome.

1. You can control width of the line.
2. To make drawing more precision, change grid settings.
