Using VF61 and IRIS motherboard using CE7 and DVI output connector

Trying to get higher resolution on dvi than the 640*480, currently do not have lcd connected, so using dvi to debug program, anyone ideas how to get at least 1024 * something

The Colibri VF61 does not support DVI. I assume you are using the Iris board’s VGA RGB signals from the DVI connector, which are converted from the Colibri’s parallel RGB interface by the onboard parallel-to-VGA converter. To adjust the VGA resolution, you need to modify the Colibri VF61 parallel RGB interface resolution as described here.
