Atari Monitor border. Hard to expand image?

Recommended Posts

Hi team,

 

Ive done a search of the forum and cant find a how to guide on how to expand the image on standard atari monitor. Screen is small as is without the wasted border space. So is the technical adjustment to make it bigger very hard? Also does anyone know why Atari designed such a border in the monitor? Seems silly but there must have been some reason?

Ok thank you. Going by that link it seems increasing screen size is bad for our elderly monitors so prehaps I will leave it.

And anyway, how were you supposed to enjoy fullscreen demos if you decreased the border size? :)

I am using overscan only in monochrome mode :) Unfortunately there is not so many demos for mono. I know only 2 - Jirka Lamac demo and the Earth from Baky. Is there some other which I do not know?

Too big border (small pic) on Atari monochrome (SM 124) may be result of old electrolyt capacitors.

It is known issue. I had such problem, but can not say now exactly which ones I replaced.

Probably those in horizontal deflection and power supply.

There are a couple but I can't remember their names right now (one was by New Trend IIRC?). Also there is a fullscreen in mono! If you look in pouet and sort the st prods with date it should be one added this year :)

Just another thought. You can build a VGA adapter relatively inexpensively and use a VGA monitor for High Resolution and the image will be edge to edge. I know it is not the same as using real atari hardware but it works quite well, and its nice to do word processing on a 17 inch monitor!

 

Here are the instructions:

There is also a mod available for the mono monitor which causes the borders to be smaller (ie - like adjusting H and VSize on the old style CRT monitors).

 

Mine's had it done, although I'm not sure on the actual details of the mod.
