Is anybody running their Amiga with a Sony Multiscan. If it works well please give a pin-out. One person said that he couldn't get the Sony to work properly until he put the composite sync to green or something like that. Thanks for any help. I'm especially interested in flat screen monitors like Sony because they have less distortion at the edges of the screen.

Im presently using the sony 1302 with a 2000 [DI had the cable made up by Redmond Cable and it works fine. As I mentioned earlier in a previous message the way I like to use the monitr or is by compressing the vertical and horizontal sizes with the controls in the back. With the reported 0.24 dot pitch and the compressed screen working with this monitor is a joy I relish more every day. If you have any info on that deinterlace board please leave a message Steve Schram

Steve, how much do you compress the images? I assume you showing a substantial border around the edges.

MicroWay will have a deinterlacer video board for the A2000 in first quarter of 88'. Retail price is around $595. But I just read a rumor from the new Info Mag that Commodore is getting close to modifying the Denise chip to support 640 x 400 noninterlace. If that's true, we won't need the deinterlacer board. I sent away for a Sony 1302 cable from Redmond Cable. I decided to get the Sony because it has less distortion because of its flat screen. The NEC and Mitsubishi both pin cushion quite a bit on the vertical outside edges of the screen. Regards.

Pete, Unless the horizontal scan rate goes up, you've just traded one form of 'flicker' for another with Denise doing 640×400 non-interlaced. And if the horizontal scan rate DOES go up, there isn't enough memory bandwidth to handle it. There just ISN'T any extra memory bandwidth now at 15750 Hz horizontal scan rate.

So it sounds like your saying the the MicroWay flickerFIXER in the video slot of the Amiga 2000 is still the best way to go? And the Denise chip handling 640 x 400 non-interlace is probably a ridiculous rumor?

640×400 with 2 bit planes (4 colors, like the workbench) would require the _same_ memory bandwidth as 640×400 with 4 bitplanes, interlaced. Not more than the Amiga has at all. Now, 4 bit planes, at 640×400 and so on, would wring out the sponge, so to speak, but you could certainly have a mode like that. It's very similar to the curretn situation where you can only have 4 bitplanes of 640 pixel stuff… you can have 6, if you'll accept 320 horizontal. One rather unfortunate "feature" of using memory in this manner is that the bit-screen mapping could get a little strange without a line buffer in there somewhere… Jay? Jay? Guess he's not listening. Sigh… –Ben–

Pete, Since I don't have any flicker problem, I don't feel any NEED to FIX it. I haven't heard anything about the "MicroWay flickerFIXER", I really can't comment. IMHO the 'solution' if one is needed is a longer persistance phosphor on the monitor. The 2080 is "supposed" to be out in January, that will be interesting to look at (pun intended).
