Angry [solved] Reduced blanking will not work

Hello,
I have an 24" TFT screen with an native resolution of 1920x1200 pixel.
And 2 systems connect to it via DVI.
One system as an FX 5700LE and the other an MX 440 card.
When using the nv driver all works. But when using the nvidia driver I can't use resolution higher then 1600x1200.
So both card's can reduced blanking, but how can I enable it in the nvidia driver to support 1920x1200?

Your card is probably limited to 135 MHz pixel clock.
The nv driver does not check that. In the nvidia driver you can disable the check for max pixel clock as well, see the README.
