Short answer No.

Long answer:
I followed this guide (and others) to pull apart the BIOS and get the Setup Utillity, from it I found this:


Quote:
Suppress If
Opcode 0x27 (2)

One Of [0x258<1>] 'Display Mode'
\Help text: 'Set Display Mode Configure Type.'
Option 'Hybrid' = 0x2 Flags 0x1 Key 0x0
End One Of
End If
As you can see, there is only one 'Option' operator, which means unless HP releases a BIOS update, I'm stuck on 'Hybrid, and, apparently HP is never going to do so.

Thanks

PS:

Just as a reference, another computer (VAIO) with a insyde BIOS has this other 'Option' operators.
