I am having problems with my 1950 monitor. When I first turn it on and it is cold, it wavers (vertical lines wavering horizontally). The dealer demo at my local dealer also does this (it is worse than mine actually). I've only noticed this problem on the (older?) 1950 monitors with a single faceplate. The newer 1950s with the darker front around the screen don't seem to have this problem. Has anyone else seen this problem and fixed it? What is CBMs stand on it? Should I send my monitor in for warranty work (it isn't really that big of a problem right now, but it has gotten worse from when I first got it so I figure I should find out before the warranty runs out). Thanks for any advise...

Both monitors waver horizontally very slightly - just enough to give the user headaches and nausea. No amount of horizontal hold tweaking helps. These monitors suck. My advice (to the buyer) look elsewhere for a better quality monitor. My advice (to CBM engineering) stop going for the lowest price exclusively all the time. Especially for the A3000, the A1950 makes the computer look bad and has made me ill. pk -- Perry Kivolowitz, ASDG Inc. ``We look for things. Things that make us go.''

In my experience, the most common cause of horizontal waver is that another monitor is nearby, and the two are interfering with one another. -larry -- It is not possible to both understand and appreciate Intel CPUs. -D.Wolfskill +-----------------------------------------------------------------------+ | // Larry Phillips | | \X/ lphillips@lpami.wimsey.bc.ca -or- uunet!van-bc!lpami!lphillips | | COMPUSERVE: 76703,4322 -or- 76703.4322@compuserve.com | +-----------------------------------------------------------------------+

I have Noticed that ANY electricial "device" can cause waves, I have a Small fan next to my machine and if it gets too close one can get nausua REAL fast, a Radio, Modem, or even Powersupply can cause the same problems. Could be interfreence from ya machine, (Do you have a 2000 with LOTS of cards) I hear that too many cards can cause interfreance. Try a metal plate on top of ya Machine, (Like I*M's have built in, their cases are metal, and cheap Clones use thinner metal and have similar Probs) C-ya. . Hay i actually ANSWERED a question for once... Wow. :wq -- yorkw@stable.ecn.purdue.edu Willis F York ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Sig? I dont' need No Stinking This Space For Rent....

When I first got my Amiga 3000 and 1950 monitor, I noticed that the picture was not always rock solid. The problem depended on how long the system had been on, which video mode I was in, and whether images were being moved on the screen. After much testing, I determined that these problems had nothing to do with the monitor itself, but rather with A3000! I called my dealer, and he told me to adjust the fine tuning screw next to the display enhancer switch on the back of the A3000. This screw is documented in the small book that came with the A3000, but I hadn't gotten to it yet. The perfect adjustment varies according to how long the computer has been running and what video mode I'm in, but I can always get a rock solid screen by fiddling with that screw. I don't know whether the problems that others have been having are the same ones, but for those who haven't tried adjusting the screw, try it! Note to the designers: it should have been a knob, not a screw! I'm thinking about hacking in a knob myself (near the front of the computer). AMC

I have read several postings here that have mentioned problems with the
1950 monitor for the A3000. Since I am buying my A3000 through the education
discount program I'm stuck with the 1950 (i.e. I can't make my own monitor
choice). So, the question is, is this jitter thing a really serious problem
or is it kind of rare? Like are my chances 50/50? I know there is know
certain answer but I'd like to know what to expect if at all possible.
Thanks for any and all replies (E-Mail or otherwise).
