Are there any good 1950 monitors out there? The monitor that originaly came with my system had the problem with minor jittering, which I wanted to correct while it was under warrenty. After 2 swaps (the first one was a dead monitor) I still have a jittery monitor, and this one has a much worse misconvergence on the edges. (All of these monitor were from the August 6 batch.) Since I appear to be stuck with the jittering problem, I want to know if the mis convergence can be fixed by degaussing. If so, how much does a degausser cost, and why the hell doesn't the 1950 have one built in - even a TV I had 6 years ago had one built in. Why didn't C= just buy the monitors from NEC instead of the disreputible company they chose? Rick

I have never seen a high quality monitor that could be set up to overscan while maintaining acceptable convergence and pincusion distortion. The only display standards which normally are overscanned are those derived from NTSC like IBM CGA or the normal Amiga display. Amiga users with high scan rate output are asking for trouble when they try to find monitors that bleed off the edge of the tube. In trying to cater to this desire in the A1950, Commodore is making, in my opinion, the wrong design trade-off. These monitors are just not capable of working well with the large scan angle that overscanned display requires. -- Peter Selverstone - Spy Pond Systems - Arlington, MA - (617)648-7468 pselver@euler.mit.edu bix:pselverstone PLINK:pselverst CIS:72527,2652

[Stuff deleted'] I'm amazed that anyone could be having so many problems with the jittery 1950's. We've gone through about 20 of them and NOT ONE has had the jitter-bug. I did see one at the Commodore office here (First one I'd seen) but other than that nada. Perhaps you should place a call to your nearest Commodore office and ask for something to be done. I've found that some stores are not willing to 'go to bat' for their customers and the problem never actually reaches the ears of Commodore. I've done so many times and have never had Commodore let me down (unless there really was nothing at all they could do). Of course I'm talking Commodore Canada, your mileage may differ. --------------------------------------- | patrick_meloy@outbound.wimsey.bc.ca | | 'The Outbound' BBS Vancouver BC | ---------------------------------------

Sony 1302 had a corner bented in up-right, with my A3000 in 640x400 mode. Mit. 1381A was worse, same corner bented out this time (both mon. has a non straight line on the right towards the upper right corner). near the corners text are out of focus, and the worst part: in certain colors, fringes appear like a magnetic field over the whole screen but not too obvious in some color. Both dealers gave me hard time , especially the latter case, which even denied it wasn't normal, and assure me it was the best spec. he had seen (the tech said). Even now if Mr. Selverstone is right about overscan cannot be achived by most monitor within specs., the fringes is still mystic to me. Now, I've given up to find another monitor but I want a near perfect one, when you are paying $500 to 600 for a monitor. My A1084Sd (Korean model, like 1080, with stereo), is at least without any problem. Mitsubishi 1381A accepts NTSC composite video, thus works overscan fine in NTSC , and I would expect it ok too in RGB analog but double the hor. scan rate. If somebody knows of a good monitor, a good manufacture, or a good dealer for monitor in San Diego, let me know. I have to return both monitor, since both places did not promise what's on the invoice , I'm putting the matter in dispute. yet looking for the perfect monitor quest, David
