Title: Question about SD/FF
Post by: dougal on January 23, 2012, 04:30:41 PM
I thought that using my a1200 with an LCD tv was enough. But since installing OS3.9 i realize 2 things. First is that PAL Hi-Res everything looks oversized. And second, if i go higher like PAL Hi-res laced the screen flicker is too much to bare without going insane.

I've come to accept that if i am going to use OS3.9 i NEED a high resolution without flicker.

Firstly, with the Indivision i've read that it can display 1024x768 using a combination of the Indivision (plus supplied software) and the AGA chipset. Is this true ?

Using the Indivision AGA will high resolutions eat away at my chip ram ?

I've seen on eBay these cheap arcade scan doublers / flicker fixers for like 30 euros. I've heard they can be easily (as in REALLY easily) to work with the Amiga. Are they any good ? Will they perform anywhere close to the Indy AGA?

Yes, and possibly higher.

Yes, though things like FBlit can help.

Some are usable, but no, not as good as Indivision and also they won't get you 1024x768.

Well, a good (100Hz) TV should have a deinterlacer built in so that hires interlace does not flicker.

Yes, using higher resolutions will eat up your chip RAM. 1024x768 with 256 colors will need 768 KB RAM.
