Can't get two monitors to run on 8500GT

[menorcarob]

hi
i have a nvidia geforce gt8500 512mb card, in a hp m8180 media center, i am running W7 64 bit, and i have the latest driver from nvidia, here is a shot of the specs (attached). i cannot get the hdmi connection to work or get it to recognise an additional monitor, i want to run extended desktop, i can run one monitor on the DVI socket, does anyone know if this is possible and what do i need, i am connecting from a hdmi to vga cable, and i have tried it with a hdmi to hdmi on a tv screen, but the vga screen says no cable attached and the tv seems to see the cable but will not display anything, i ahve tried all of the bits in dispay settings and in the nvidia control panel but have got no where, any ideas would be greatly appreciated.

thanks
robin

hi
i have tried that, someone suggested that it could be the cable, some hdmi cables need a converter, any ideas

does your hdmi cable work? when it plugged. it should give a signal
