I built a Windows 98 pc and would like to use my 1080p monitor as a display. It is able to correct the aspect ratio to 4:3 on the most common resolutions like 640x480, but the pixels do not seemed to be scaled properly, so fine 2d elements look kind of garbled. Even worse though is that the common dos resolution, 320x200, cannot be aspect corrected by my monitor so it is 16:9 stretched. Is there some sort of device that could handle these common pc resolutions so they could display properly on a 1080p display? I've asked about using a framemeister or ossc, but I don't think the ossc would help because it's not a scaler, and I'm not sure if the framemeister would be good for a pc. It would also be nice if it didn't cost as much as either of those.
I do have a 5:4 LCD which a lot of people seem to use in retro pc builds, though I'm not sure why because then the image is either stretched vertically or not aspect corrected that well either (at least mine can't even do aspect correction).
