I have an old Atari 800 XL in great condition, but it only seems to display readable video output on my Zenith monochrome monitor. When I plug the DIN to A/V cable into any TV, I get the color channels horizontally separating several pixels, which makes any fonts or other small sprites rainbow and blurry. I was hoping I could get some information on what causes this, if it is incompatibility with new TV's or the video chip messing up, I'm not sure. All I know is that my monochrome monitor displays things perfectly. I have heard something about NTSC vs. PAL and I really don't know which this machine is or what difference it would make considering one of the TVs I tested the machine on is European.
Thank you to anyone who can help me on this. I can provide pictures if requested.
Thanks,
