I see a Commodore 1084 Monitor that would match my Commodore 64C perfectly for a good price on ebay. However, the screen displays lines on the top portion of the screen. The seller notes this in the description also. It looks to me like the many settings at the back aren't tuned correctly, because my Apple Monitor III gives very similar lines when not set up exactly so. It has around 4 different knobs to fiddle with. I'm assuming a commodore monitor would be similar. What do you think, is it a bad input or incorrect tuning, or do you think it's likely that the monitor is actaully broken? It'd be great if I could get the opinion of somebody with experience with these monitors. Thanks!
