#1 switch off laptop monitor when crt is active

[Anonymous]

Dear author,

your code works very good a and exactly as documented.
On a dell inspiron 510m notebook with i855gm chipset.
Thanx a lot !!

Now I'am asking wether it is possible to switch off
the laptop lcd at the time the external crt is active.

Regards,

Valentin Rottmann
