NTSC Screen on SVGA Monitor

[Gaeokerena]

Hi All

I have just got hold of a 17in Axion SVGA monitor to connect to my 4000d via a Arxon Scandoubler. However, the monitor will only accept 60hz as its default, not the 50hz required for a double scanned PAL screen.

I have switched my 4000d from PAL to NTSC to use the monitor in this way, but whenever I try to play any sort of PAL game the image is pushed to far down the screen with some actually missing from it.

Is there anyway the position of the NTSC can be modified or even any other solution

Cheers

Hmmm...

Turn off any patches that give you a black screen border for a minute.

Now go into Workbench:Prefs/Overscan and use the black squares to manipulate your Amiga video so it squashes into view.

Use your monitor's resize buttons/dials to get the picture in view.

Bare in mind that a PC monitor's visible screen area is 4:3 ratio and NTSC is not a 4:3 ratio resolution.

Video modes are not like VGA modes, they are not at this 4:3 ratio such as 640x480, 800x600, 1204x768 etc.

To keep your pictures from looking fat or stretched in any direction, fill your entire visible screen WIDTH and shrink your screen height by about 5% or so to keep aspect-ratio.

It'll look like widescreen if you're using full overscan with NTSC but you'll have that much more than a normal 640x480 resolution (all compressed into the space viewing area).

If Overscan prefs doesn't work, you could try booting your machine in PAL mode from the early boot menu (hold both mouse buttons at startup).

Remember,a digital monitor with seperate saveable `channel settings' would be very handy for Amiga users because of the variety of screenmodes we encounter.

Sorry, I did not explain this well enough

Using Workbench is fine, but booting from any disk based software, especially games, give this problem!

I get you...

Workbench loads finely tuned custom overscan options whereas games
just force the basic 640x512 in PAL.

However, even my crumbly old monitor can be dialled so that the entire
Amiga video area is within sight.

It's a real pain if you don't have a digital monitor because when you
switch back for games you have to resize to a different screen aspect.

If you have a digital monitor, check for options relating to centering
and vertical/horizontal resizing as well as pin-cushion.

Hopefully you are luckier and will be able to save seperate settings
for when a game loads up.

:-)

You could always try using the early boot menu to FORCE games to run
in the monitor settings you have at present. Squashing them into NTSC
or whatever you choose.

I know some Fairlight intros allow you to switch between PAL/NTSC
screen sizes when the game boots, overriding the early boot menu.
