At a meeting with other Amiga (ummm...) enthusiasts/developers we discussed the problems of perceived flicker, witnessing the top 1/3 line flicker on an A3000. One person mentioned that he had never noticed flicker on his TV until he had a proper antenna and tuned-in TV. After that, flicker was quite evident. An out-of-tune or poor signal effectively "smudges" the image. One way to allieviate the flicker problem on the Amiga, is to blur or smudge the image, so that adjacent pixels can mix before they hit the eyes. A possible (cheap) way of achieving this is to smear petroleum jelly (aka "Vaseline") on the monitor face. This is likely to produce the desired interference patterns and flicker reduction. We did not test this idea, but would be glad to hear from anybody who's tried. I must warn you that such a modification will probably void your warranty, unless the work is performed by an authorised C= service centre. Are you listening, Scott Hood? Is this a hardware modification which C= could perform during manufacture? Or is it something the dealer should do? How about supplying a free jar of Vaseline with every Amiga? OK, I'll let you off the hook.
