Short: 704x480/60Hz monitor driver for AGA Author: bitbrker@ionet.net (Terry Miller 2) Uploader: bitbrker ionet net (Terry Miller 2) Type: driver/moni Requires: AGA Amiga and a VGA monitor. Architecture: m68k-amigaos Distribution: Give it to everyone that uses AGA+VGA monitor! 704x480 31.55kHz/60Hz monitor driver for AGA Included in this archive is a hacked Overscan.prefs and a hacked DBLNTSC.info that allows a larger horizontal overscan in 31.55kHz (704 instead of 640). As most people know, most VGA monitors have trouble with 27kHz (the default DBLNTSC rate). And at 29kHz, most VGA monitors will present a "washed out" picture. That is because they really were designed for 31.5kHz as minimum for the horizontal scan rate. The files in this archive mostly alleviates this problem by providing a 704x480 (352x240 in LoRes) and a 31.55kHz/60Hz scan rate. There are also a lot of VGA monitors that won't display a 50Hz DBLPAL display either. And of course, 50Hz screens have that annoying flicker. 60Hz is really the minimum you should go for viewing comfort (trust me!). Problems: The hardware seems to require skipping the first 2 lines or so or the display will look messed up. This is of course set properly in the Overscan.prefs file, but I'm warning you so you won't be freaked out if you try to modify the Overscan settings. So, the vertical ends up being 480 lines rather than 482. 256-color mode in hires is a bit sluggish, but its still usable. But of course, this is a bandwidth problem common to just about any mode other than 15kHz NTSC. I have found 128-color mode to be quite comfortable, though. In any case, this will provide you with an acceptable display until you can upgrade your Amiga 1200/4000/etc. with a Picasso IV or CyberVision card. Another benefit of this monitor driver is that it allows a 50kHz/14-bit sampling rate for the audio! Your WAV and MIDI files will sound great! Warning: The Overscan Prefs program will be confused by the altered Overscan.prefs file. This is normal. However, do not try to alter the DBLNTSC overscan settings with the Prefs program or the hacked values will be overwritten. Notes: The Horizontal Sync may have to be adjusted for your monitor in order to center the display. The HSSTRT and HSSTOP tooltypes in the DBLNTSC.info file have been set for my monitor so that the Amiga output is in about the same position as my PC laptop's output. That way I don't have to fiddle with the controls when I switch between computers. You may have to use MonEd to get it just right for your monitor, though. Enjoy! ----> Tm2
