But where do the underlying modelines come from? Does the converter<br>
provide them? I don't know the Hsync and Vrefresh limmits, but this is<br>
a modeline from one of my panels, which comes the same with my CRT's.<br>
So I guess it's a vesa mode:<br>
<br>
Modeline "1024x768x60.0" 65.00 1024 1048 1184 1344 768 771 777 806 -hsync -vsync #(48.4 kHz e)<br>
<br>
You can try adding it to your monitor section.<br>
<br></blockquote></div>Yes, the modelines come from EDID on the converter. I can try adding the 1024x768 modeline, but I'm not optimistic it will solve the problem. I think the problem is essentially what Mike described--the converter is expecting/assuming a 16:9 signal and thus converts it via letterbox for my 4:3 TV.<br><br></div><div class="gmail_extra">Karl<br></div></div>
