- Andy,
- Looks to me like this guy is reffering to say A1200 and
- A4000 owners who only have VGA monitors and not C= 1080s, you see this is
- how it works, normal Amiga screen modes (all those available to a 500,
- 600, 2000, 1000, ect.) are sent out of the Amiga as 15 htz (that's
- the refresh rate) video. But 15 htz is too slow to handle deep screens
- that's why anything over 200 (256 PAL) pixels in height will flicker like
- mad, these are the interlace screen modes and I've always been of the
- opinion that their utterly worthless but maybe somebody out there knows
- better than i. At any rate, AGA machines can put out two types of video,
- 15 htz for normal Amiga video modes, and 31 htz for flicker-free output of
- video modes with more than 200/256 pixels of height. Now this 31 htz
- video out is the kind of thing you'd hook up to a VGA monitor, whereas the
- 15 htz would go to say a C= 1080. Now the 31 htz out will output
- normal Amiga modes, but on AGA machines it'll actually do it in 15 htz,
- The problem is that a 31 htz monitor needs to recieve 31 htz signal,
- so-called multisync monitors can take signals from several htz ranges but
- most (even some of Commodores) won't sync to 15 htz (mainly because it's
- insanely low for a refresh rate, most PCs get aroun 60-90 htz these days,
- as do Amiga gfx boards) So the trick is alot of Amiga A1200 owners
- have monitors that will only take 31 htz output, so when there amiga trys
- to display a 15 htz Normal Amiga Video mode screen, they'll jsut get crap,
- fuzz and such from there monitor. Now the solution to this is to a) buy a
- harware flicker fixer which will double the 15 htz signal to 31 htz before
- it leaves the Amiga make it safe for 31 htz monitors, (the A3000 has one
- of these built in, so if you're listening Larry one more reason to buy!)
- or b) to run the software flicker fixer that comes with AGA machines, this
- program will do the same thing as the Hardware flicker fixer, but the
- trick is it must be run first, so if your game runs from WB your fine
- since the user can just run the flicker fixer before opening your game,
- but if your game has it's own boot disk then you're effectively screwed, I
- guess there maybe some way around this but I don't know for sure, and I
- reckon it's probly a pain in the ass for the user.
- Well that covers it good luck,

- PS
- I have no clue what the sound comment meant,
- anyone?
