Powegraph v9900 compatability

[zhulien]

I lent a friend d my power graph v9990 to try out some things on his cpc4atx.   The power graph did work on my real 6128 plus with a Loewe scart tv vga input which is a pretty old lcd TV.

On my friends TV he just gets a blank screen I believe and a loud noise (from the robot demo).  Symbos v9990 seems not much better.  

I am thinking its the monitor frequency range thst is why he can't see anything.  What monitors or TVs have any of you tested v9990 successfully on?  Does the v9990 output 15.6lhz or higher frequencies?

Any info appreciated.  Of course it could be an incompatibility with the cpc4atx?
