DBLNTSC doesn't flicker for me. PAL always flickers some, doubled or not. You could try Productivity mode or Euro36/72 if you really want to get rid of the flicker. Dale L.

John, I am using occasionally the DblPAL mode on a Samsung monitor with my A4000; the monitor will display from 30 kHz – 120 kHz. In the ICcontrol preferences is selected "Modus ubernehmen" – no idea what that is in English (it tells the system somehow that it has to emulate a flicker fixer). There are still some applications which ignore this and _force_ a 15 kHz screen. But when it works, also the _interlace_ screens come non interlaced – with 49 Hz, however. And on a monitor with short flourescent time (?propably not genuine English either?) this is clearly flickering. It I can, I use productivity mode, which my monitor measures as 68 Hz.

Ok… While the AGA Amigas don't have a built-in de-lacing system like the one found in the A3000, it can do a decent job of converting screenmodes into other screenmodes. However, since this is a feature of the OS, any program that bypasses the OS has ultimate control of what screenmode it uses. First, make sure you have the proper monitor drivers in the DEVS:Monitors drawer. These files are self-running programs. The startup-sequence will run them on bootup, or you can run them by double-clicking them. Once a monitor drive runs, it addes itself to a 'database' that the OS can access. Programs can also access the monitor database, if coded to do so. Use the Overscan Pref to make sure your monitor can display the default (~27-kHz) scanrates of DblPAL, DblNTSC, and Multiscan. If your monitor doesn't sync rate, use the VGAOnly program. VGAOnly, is a flag file that modifies the sync rates to more closely match VGA rates (but this reduces the maximum overscan.) The IControl program has a MODE PROMOTION option, that attempts to substitute a DblPAL/DblNTSC for PAL/NTSC screens (at an OS level.) However, this promotion software is limited. Another program found in the AmigaUser LIB 3 (Screen Utilites), will a larger varity of resolutions & screenmodes. It will even allow to to select which resolutions get promoted, and into what.
