#A4000 & 1960 Monitor
12 messages in this thread
I have a friend who has just purchased a A4000 along with a 1960 monitor. He is
having trouble displaying a centered screen in Double Scan Mode (640 x 400).
The screen is closer to the left edge of the display than the right edge of the
display. We have tried using the preferences editor OVERSCAN to move the
display, but it does not allow this. Has anyone else experienced this problem?
Does anyone have a solution to this? Any help would be appreciated.

Use the picture adjust knob on the side of the monitor.
He says he has adjusted the controls on his monitor and the best he can do is
get the image about 1/4" away from the left edge leaving about 1.5" on the
right edge.
It seems to be a peculiarity of the 4000/1960 combination; my Double-
NTSC-No-Flicker mode (which is what I think you're talking about) sets up
at the extreme right-hand-side, to the point where I actually get a bright
line on the right because the gun-trace just can't go no farther….
Don't expect help from Commodore on this; your friend DOES have a
fully-useable (if off-center) image, and the 1960, for all its quirks, is
the cheapest "multisync" monitor you can buy that handles all computer-
specific scanrates AND all TELEVISION-specific scanrates: I saw a gorgeous
multisync at my dealer's store, and it had tight-enough oscillator-control
that the image barely moved as the computer switched from one driver to
another — but that puppy cost eighteen hundred bucks, too. (YGWYPF.)
There is a new Commodore monitor due on the market in the UK by the end of
this month that is supposed to correct all these display problems with the
AGA modes and will retail for nearly half the price of the 1960.

I hope so, if for no other reason than that the Amiga is already known
widely enough as a "quirky" computer (or maybe that was us Amigafans who
got that name): One almost gets the feeling that the 1960 monitor was a
"rush job", like the Irish-built A1200s whose first entire production run
went into the crapper, literally, because not even Wang could make them
work (I read of something like 80% returns); of course the whole AGA
project ended up as a rush job because all the PC-thieves were blowing
smoke up one another's asses about "real-time video" and "16 million
colors" (which, interestingly, was usually only in normal-VGA mode; in
SVGA the palettes drop to maybe 32,000 colors, so what's the point?), and
CBM apparently feared losing what little market share they had….
AGA was not a "rush job". It was first shown to developers in Sept. 1991.

'fraid not. AGA was demonstrated to devs about 1.5 years ago.

Yeah, and Windows was "shown" to developers in 1986, too…
Thanks for the response. He has tried talking with Commodore, and you are
right, they said that there was nothing you could do about it now, but that
they are working on new monitor drivers which might solve the problem.
VSIZE on the 1960 should be set to auto and WIDTH to add. He also may want to
try reducing the number of loaded monitors to double NTSC and NTSC. Use
ScreenModes and Overscan to set and save the maximum screen size. Worth a try.
Thanks for the suggestion. I'll let him give it a try.
