Ok, I've verified that I'm seeing 25 custom modelines created as they all show up in Arcade_OSD. I've attached 3 pictures of what my Arcade_OSD looks like. The first has the initial batch of modelines created (I don't think they are the magic ones, as they don't start with an xres of 1234). These all display properly. The second image is of some of the "Magic" resolutions. None of these display properly, they all flip. I've tried changing the Hfreq all the way down to 15300. So my modeline eventually looked like 15200-15300, 49-65.00, 2.000, 4.700, 8.000, 0.064, 0.160, 1.056, 0, 0, 288, 448. The third picture show's what the flipping image looks like. I'm wondering now, if the issue isn't the fact that the xres is too high. If it's trying to display 1234 as the X value, it will never show properly. I think that 720 is the max value that this TV will display. I've got the desktop running at 720x480, anything higher and it also will flip.
