    Probably pixel clock is a bit too low in optimized mode compared to generic mode (when tweaked for PAL 1080p).
    You can try increasing h.active for 320×240 to 360, as you may get a more valid active frame (1440×1080).

    EDIT: actually an idea can be to use 256×240 mode to increase pixel clock (horizontal is multiplied by 5 as opposed to 4 in 320opt mode). You will need to experiment with h.active to get a suitable active frame, and zoom control on your TV to get acceptable aspect ratio.
