burkjon: Video drivers do not have an option to specifically force 4:3 (oh how I wish they did), only an option to maintain the aspect ratio. If DOSBox or ScummVM are not forcing the image to be 4:3, it will still be stretched because 320x200 is a 16:10 resolution.
I know all this. My point was that since video cards by default stretch the image to full screen anyway, then it shouldn't matter to Joe Sixpack whether aspect ratio is true or not. So there is no reason not to set it to true by default.

Maighstir: ...most users likely expect their games to fill the screen rather than pillarboxing them....
Actually I would like a compromise between true aspect ratio and full screen. Something like a limit on the distortion while within this constraint maximizing the screen filling.

Unfortunately there is no setting for this in Dosbox, but I could calculate my desired scaling manually and set it...

I have noticed examples of both defaulting to stretching and to keeping the correct aspect ratio depending on the machine (though there are only Intel graphics in my sample set at work), so I'd say it varies.

What kind of person would actually prefer a stretched image? I can understand it if people are lazy and don't care, whatever, but actually wanting everything to be stretched? It drives me crazy when the aspect ration is wrong.

In my experience I have found that GOG has aspect_ratio=true set for 320x200 games that are supposed to have it. Not every 320x200 game is supposed to be stretched. I've attached a good example below. Having aspect_ratio=true set for all games is like having your TV set to have the image fill the screen, regardless if the content is 16:9 or not.

burkjon: if the game was released on DOS then it should have a 4:3 aspect ratio, ovals or not.
It shouldn't. Aspect=true should be used for games running in non 4:3 resolution, regardless of the monitor. It is meant for games running in 320x200 (VGA 13h), regardless of the monitor's resolution, not for running 640x480 games on 1920x1080 monitors.

We did have this discussion a couple of months back. Take a look at posts , [url=http://www.gog.com/forum/general/dosbox_rendering_defaults_must_be_overhauled/post13]13, and [url=http://www.gog.com/forum/general/dosbox_rendering_defaults_must_be_overhauled/post32]32.

This is exactly what the OP is saying. His point was that all DOS games running in 320x200 were meant to be stretched to 4:3 on CRT monitors (because back then basically only 4:3 monitors existed), so for all such games aspect_ratio should be set to true.

What about games running in 320x240, or 640x480? Should those also have aspect=true or not?

No. They didn't use the non-square pixels which is what aspect_ratio corrects.

EDIT:
burkjon's post which you quoted was a response to Flaose who wrote that some 320x200 were meant to be played without aspect_ratio (i.e. in 16:10). burkjon replied that that wasn't the case because all monitors were 4:3 then. He didn't imply that aspect_ratio should be switched on for all games.

Ah, so it was the post I replied to, not the content of it. Quite a few Dos games didn't run in a 4:3 resolution, which was the first part of my answer, and the second was me remembering I've read the same stuff before.

No worries either way though :)

Yes, exactly. No worries :)

This is damned if do, damned if don't setting. Some people don't want it stretched, and others do. I typically go in and change a lot of config settings. Just learn dosbox and move those settings over when you install it.

Keep in mind that gog is looking for the best compatibility settings, and not looking for the best config for your machine.
