[I posted on this once before, but I think esunix fed it to the lineater.]
For about two weeks now I've had an A3000 and a Sony CPD-1302 multiscan
monitor. The Sony is beautiful, the colors are far brighter and more
vivid than the old NEC Multisync (the original model) or the A1080.
But I've got a swimming noise pattern in the image. It is horizontal
bars about 1/8" to 1/4" apart, that swim vertically up or down the
screen. The direction and speed of the swim varies with the intensity
setting on the Sony. The noise is present both with the Display Enhancer
enabled and disabled.
Any ideas what's causing this, and how to cure it? I tend to suspect
poor grounding/shielding in the video cable. The place I bought it from
threw in a "free" cable, so it's probably the cheapest thing on earth.
So before I home-brew a cable out of coax, is there anything else to
check?
If the video noise can be corrected, I'd strongly recommend the Sony
over any other monitor I've seen hooked to the Amiga, including the old
NEC Multisync, the CBM A1950, and the NEC 3D. The colors are incredible,
and the centering and size adjustment pots on the back have enough range
to come within 1/8" of the sides of the CRT, and can run off the top &
bottom of the CRT. This is far more overscan adjustment than my old NEC
has. If you're willing to open it up, you could probably get more
overscanning on the sides. (But my warranty isn't up for a long time,
and I don't have a service manual, so someone else will have to try it.)
