Well, I can see the 50Hz flicker when running demos, too. It's not just
because the picture is stable.
Of course, I also have 60Hz lights. When running European software I'll
often shut off the lights and I notice the flicker less.
Demonstrations of music, special effects, artwork, etc, done on the
computer. Part of C64 and Amiga culture. Called either 'demos', or
'Eurodemos' because they're usually written by European demogroups and
they often completely fail to run on 60Hz screens. (I think they take
pride in making their programs not work on North American computers.)
There are still demoparties in Europe with prizes for Amiga and C64
entries.
I definitely
notice the 50Hz vs 60Hz difference on my computer.
It is visible when using a still picture like a computer
output. 60 Hz gives a more stable view, but on the other
hand, the poor NTSC coulour signal just damages the view
again, so again the result is bas - taking this and the
lower resolution (less horizontal and vertical lines in NTSC)
I'll prefer the flicker.
Less horizontal lines? Televisions are analog horizontally, and all of
the computers I know of generate the same number of pixels horizontally
whether they're in Europe or North America.
THe best was still using PAL with
60 Hz - some homecomputers of the 80s could be programmed
for that - less flicker and high resolution and biliant
(or at least as briliant as a narow band colour signal
can be) colours.
Certain European Amiga models would be able to generate 60Hz PAL. I don't
know what else could, but I've never come across a European computer.
I might
not notice it with a TV signal, though - I've never watched PAL
television. (But I've watched 50Hz 'EuroDemos' on the TV.)
EuroDemos ? Whats that ? I used an SONY TV for the ATARI ST, 10 years ago.
My brother used a Sony TV for his C64. Which kind of sucked because it
only had composite input.
