Well looking at the picture you posted, it looks to me that the picture is moved over. Could be the monitor is triggering off the wrong edge of a sync, or since the text area will be a nice square block unchanging down the side of the screen, its syncing off something else, like the beginning of the text area. DOS in the 8088 era you use to be able to access the video ram and change the colors. I did it, but I have no idea what it would be like today. I figured you could put something lighter on the screen and see if its triggering in the wrong spot.
Looks like on a long text line, it prints during retrace and smears everything on the line. Does the printing look symmetrical? not too wide?
Black bars running vertical would give it a sync option, how about a round ball solid 80% of screen.....
I think it could possibly be too short and distorted a horiz scan, it is suppose to be a saw tooth, the horiz osc may be giving a distorted saw tooth.
