Title: FlickerFixer vs. ScanDoubler?
Post by: arnljot on December 27, 2007, 06:12:04 PM

Same difference?

I've soon got a working Amiga1200, But I don't want an old Amiga Monitor. I want to use my 19" flat panel with it.

So what's the difference between a flicker fixer and a scandoubler?

I kinda understand it from the names... But I need to really understand the difference.

Also, when is it important to know if the scandoubler/flickerfixer is 24bit? Ofcourse if you want AGA, but is it with a scandoubler or a flickerfixer or both?

I'm considering the Micronik A1200 (a friend has it and will sell it to me cheap).

I'll get to use my flat panel, but what will I miss if it doesn't flicker fix? Rock steady interlaced displays?

Hello.
Flicker fixer is a "deinterlacer", or sort of.
Scan doubler is a.. well scan doubler. It doubles the scan rate of amiga graphics from 15kHZ to 31kHZ. Making it work on a standard PC monitor. However, using a LCD display. is a whole other story. Ask some of the other guys, they know that better than i do...

But if you plan on buying a SD/FF be prepared to dig deep in your wallet. They do not come cheap and are rare. They do pop up on ebay from time to time...

A Scan doubler allows you to display Amiga 15Hz screen modes on a standard computer monitor - it effectively doubles the scan rate to something that all monitors can handle.

A flicker fixer gets rid of the flicker that you get with interlaced modes - these will still flicker if you use a scan doubler without a flicker fixer, so you are right, you will miss rock-steady interlaced displays.

I don't know about the digital bit capability of them though - sorry.

I've got a Scandoubler on my A1200 but it won't sync with my Samsung flatpanel.  I'm using with an older 19' Hitachi crt display which syncs up just fine.

I've tried the scandoubler with other Amiga systems and had the same result....

Switch to 60Hz on the Amiga (If you have kickstart 3.1, hold down both mouse buttons on reset and press space).

Your Samsung flat panel will not sync to 50Hz
