The graphics card driver will allow you to select the tv option when it can 'see' one attached. Make sure that all the cabling is in working order and that if there is a switch on the scart plug that it is in the correct position to transmit data to the tv - not the other way around. Also try reducing the resolution of the display and also the refresh rate, this may help you to get a better image on a tv.
I did manage to get the TV switch to operate in the advanced options in displays once, but there was still no display on the TV. I think there is something wrong with the graphics card I will contact Mesh support and see what they say many thanks Ray
