Garner,
Thanks for your insight. We changed some values in the Horizontal & Vertical Timing under the Matrox board tab and now we are able to see the graphic on our Miranda switcher!
Niek, Im not sure if you are migrating from Deko too, but we just came to the conclusion the Deko must be squeezing the files during the export or saving process from Deko file to TGA file. We created a full screen graphic within the Xpression and did not have a problem with the graphic filling the whole screen! Not sure if any the file formats from deko would act differently, tif, jpeg, etc
