720 x 480 Apect Ratios Issues

[Wheemer]

When I use 720 x480 the picture seems to be good and I like the idea of not scalling the video source. However I usually use "source" as my aspect ratio, since fill stretches my 16:9 video files. However the "source" setting when using 720 x 480 displays a horizontally compressed image. Is there any way to fix this? And does anyone else experience this problem?

Thanks!

I think this is what you're looking for, adjusting video horizontal & vertical size & positions: Setup>Detailed Setup>MultiMedia>Aspect Ratio Settings

Works best if something playing (or paused) so you can see the changes as they take effect.

Could you go into a little more detail about your setup? What is 720x480? your resolution?

Yeah, I'm running an MX 440 svideo ouptut to an SDTV. I am setting 720 x 480 as the display resolution.

As far as adjusting the aspect ratio, I have been able to use 120% for horizontal and 104% for vertical. This produces acceptable results. However, what's strange is that I do not require any larger adjustments horizontally with a display resolution of 800 x 600. I can set both vertical and horizontal to 104%.

Why would this need different settings for different display resolutions? At 1024 x 768 display resolution I can keep both these settings at 104% aswell. Only seems to be 720 x 480 that is picky.

I'm no expert on this but I can guess at why the difference for the different resolutions...800 x 600 and 1024 x 768 are both 4 to 3 ratios, which is what a SDTV basically uses for display(ratio of horizontal width to vertial hieght of actual display). If you divide the first number by the second number for each you get a ratio of 1.333...

However, 720 x 480 is a 3 to 2 ratio. That gives you 1.5 decimal. From that it is obvious why you need to use a higher %(of adjustment) for one ratio over the other to achieve visably similiar results.

I hope that made sense as I typed it out fast, as I'm about to log off. Oh well someone will correct anything I said and explain better. Lots of great people around here.

Makes sense... Thanks. I've tested out the stratching via the horizontal percentage and it seem to be working fine so far.
