With everybody getting multisync monitors and talking about dot pitches of 0.31 and 0.28, etc., I was wondering... What are the "specs" for the standard Amiga 1080/1084 monitors, for comparison's sake? What's the dot pitch? Etc.? I looked in my 1080 manual and found none of this information.

Here are the specs on the 1084D monitor. Picture tube: 14 inch, in-line slot, pitch 0.42mm Display screen: 13 inch, measured diagonally Deflection: 90 degrees Resolution: 640x200 lines, 640x400 interlaced Raster frequency: 60 Hz Line frequency: 15750 Hz Character field: RGB, RGBI - 2,000 characters There's more, but that's most of the elementary stuff for non-techies... -- John M.

Interlace does work on all the Commodore PAL/NTSC Amiga monitors, if not, the monitor is probably broken and needs a visit to a service center. -- George Robbins - now working for, uucp: {uunet|pyramid|rutgers}!cbmvax!grr but no way officially representing: domain: grr@cbmvax.commodore.com Commodore, Engineering Department phone: 215-431-9349 (only by moonlite)

There are a bunch of older 108[0|4](S) monitors that display interlace as a kind of "double-interlace". Instead of interleaving the 2 frames, they are displayed on top of each other. This has the nasty effect of leaving whole scan lines blank where the second frame should be. There are two dealers in my area. One never heard of the problem, and would charge me a bench charge to bring in the monitor so they could look at it! The other dealer knows about the problem, and he even has one of the monitors that has this problem in his store. He says he has tried to find why this happens a few times, and can't seem to find a thing wrong with the monitor. There is also a television repair shop that replaced my fly-back transformer when it blew (got it done in a week, as opposed to 6 weeks the authorized Commodore repair center would have taken), he looked it over and couldn't see anyting wrong. Many people have reported this, but noone has been able to fix it. Some are worse than others. Many people say once the monitor is fine until it heats up, others only have this problem occasionally, and we'll mine just seems to be stuck in double-interlace forever... ...alan ----------------------------------------------------------------------------- internet: commike@cs.buffalo.edu | bitnet: commike%cs.buffalo.edu@ubvm.bitnet | uucp: ..!{watmath,boulder,decvax,rutgers}!cs.buffalo.edu!commike Real-Life: Alan Commike - SUNY @ Buffalo, Buffalo NY Q: How many computer scientists does it take to change a light bulb?

A 1070 was in there somewhere. All these were fine in my opinion. Then came the dreaded 1084 made by Magnavox. JUNK, crap, garbage!! These are the ones that you constantly here about snapping and dying. Where I worked, we had them being returned in droves! Then came the 1804S which was the same monitor in stereo, with the same problems. De-interlacing an interlaced screen whenever it wanted to, poping dying, unusual shaded bands going down the leftside of the screen, scanlines at the bottom of the screen doing very flaky things, ect... Then came the 1084sD, made by '?' (maybe magnavox, but certainly a different monitor then above). This one was wonderful. Picture was clear, contrast was perfect, scanlines were closer, most of the above symptoms were gone and they flickered a lot less. Well, for some reason CBM ended up selling a non-stereo version of the D, but it was still a great monitor. Then I hear through close people that someone in the new improved CBM brass let the contract with the makers of the 1084D go un-renewed!!! And guess what, all the new monitors being shipped now are back to the old junk, crap, trash magnavox's!!! Why? Explain this to me? $299 for a monitor is a great price, by why sell a junk monitor with a $3000+ '030 workstation. (2500/30) and why not continue selling the 1084D(s)????????????????????????????????
