- Well I have two of said cards and I was trying them out just today. With one
- of the cards, there is scarcely any border on the left side screen at all, and
- with the other, there is a border, but the graphics display is substantially
- shifted to the left. This effect is on the RGB monitor - I had the NTSC output
- going to my 27" TV, and the video looked perfectly centered on it. This
- experiment was with the same machine, same cables, same monitor, same
- everything.
- The fact that the two cards do different things convinces me that there is
- something you can do to fix it, or that the cards are defective and one is
- worse than the other. Or is there another explanation? I sure would like to
- know.
