Ah, I see. Thanks.

Looks like you were correct with the 155 limit for 44.

Indeed it does. I had regarded this as unlikely given that, after all, the driver simply can't know how much blanking reduction the monitor will be able to cope with.

I do get the timings printed with -logverbose 9. I also get a message to the effect that reduced blanking was used to get the pixel clock within limits. What I don't get is the timing actually being used. Looks I have to figure out the values myself (and see how to teach the nouveau fb to use it).

Thanks for your help.
