Nils & Liam,
Thanks for the reply. I will try the given suggestions. The problem I 
think is the V-freq that is wrong and I hope that the change in 
resolution will work.
I cannot use lspci as not only the resolution is apparently out of range 
but also the character set used is wrong when in a terminal.
I let you know if any of the gien solutions work.
Thanks anyway,
