60Hz used for external displays on laptops

[Martin Willemoes Hansen]

Hoary on a HP NC4200

The only refreshrate available is 60Hz, a HP NC4200 should be able to do up to
100Hz, depending on resolution.

Using an external monitor, or your panel? If your panel, it has a fixed rate of
60Hz.

Using laptop-screen (Is that the panel?).

[Daniel Stone (daniels)]

Yes. That has a fixed refresh rate of 60Hz. But thanks for your concern.

Okay, im still confused tho, the laptop should be able to use 100Hz how come
there is a fixed 60Hz rate?

it can drive external monitors at up to 100Hz, but the internal panel has a
fixed rate of 60Hz.

Aha, makes sence.

I have just pluged in an external monitor and it also uses 60Hz, is it posible
to configure ubuntu with two different refresh rates? one for panel and one for
external?

Same issue with Breezy preview 1. External monitor is also using 60Hz and there
is no way in the gnome screenresoloution dialog to setup the external monitors
refreshrate.

I think there is already a bug open about coping with multiple displays more
effectively...
