Sorry I wasn't precise. I was not referring to the original signal, but the general issue with 1024x512, after improving timings for flatscreen already. I generated more suitable 1024x512 signals (with relaxed front/back porch timings) that are accepted but misunderstood. Peter _______________________________________________ QL-Users Mailing List
