Appears to be impossible to get hold of anyone . Have tried waiting on phone. We are now considering leaving Virgin.
There are people on this board that can make suggestions for you. You may need to elaborate a little on your equipment and set up, cables used, inputs selected so they can advise you.
Thank you for your post and welcome to the forums.
I apologise for the delay in response here. Just as @Juventino has advised, is it possible you could expand/elaborate on what is happening here? Thank you.
