11 years agoHi Andy,
Could you please provide the error message when the control panel (version 2.1 or 2.0.1 ?) is trying to establish connection to your DE1 board ? The VGA output displays the blended color bars image could be the result of 1. the control panel is not connected or 2. re-compilation under a different version of Quartus II without additional setting in .sdc file.
