><br><br> You could try adjusting it to something more like this:<br>ModeLine "ATSC-1080-60i" 74.25 1920 2060 2116 2200 1080 1082 1088 1125<br><br> I added 100 dots of black on the right hand side and removed 100
<br>dots of black on the left-hand side (i.e. changed 1960->2060 and<br>2016->2116). That should move the screen, but it won't move it anywhere<br>close to half a screen width.<br><br>> Since it looks good on the monitor, why is it so far off when displayed on
<br>> the HDTV?<br>> Not being a that familer with modelines, is this a modeline issue or do I<br>> need to look elsewhere?<br>><br>> Does anyone know what needs to be adjusted to get it to shifted to the left
<br>> hand side?<br>><br> You might try different combinations of [+-]hsync and [+-]vsync at<br>the end of the modeline:<br>ModeLine "ATSC-1080-60i" 74.25 1920 1960 2016 2200 1080 1082 1088 1125 +hysnc -vsync interlace
<br><br><br> It definately sounds like the HDTV has having trouble finding the<br>sync pulse. Strictly speaking, HD-component requires bi-directional sync<br>signals, and that's a much harder thing to generate (correctly) from RGBHV
<br>like VGA. I don't know if the A960 does that, or makes the easier<br>uni-directional sync. Any jumpers to twiddle on the transcoder?<br><br>-Cory<br><br>--<br><br>*************************************************************************
