We do get an image at 1920x1200, but the monitor says it's only at 58Hz, and measuring on the DSI signals does seem to confirm that the update frequency is about 57.7 or 57.8Hz (it's pretty hard to get a good measurement). It looks like it's the lines that are too long, by a time that corresponds to about 80 pixels. But all the frontporch/backporch/hsync values look sane and completely standard for that resolution. Setting samsung,burst-clock-frequency explicitly to something large enough or letting it be derived from the 154MHz pixel clock makes no difference. Any ideas? Thanks, Rasmus
