My daughter has an Asus rog g20 gaming PC & a Hitachi L24DG07U TV which I have connected a HDMI cable, but the TV does not recognise it. The screen is blank. She is running Windows 10 so at the moment it is connected via a VGA cable via the graphics card, which is ok but obviously there is no sound. Really would like advice on how to get the HDMI connection up & running. Any help would be much appreciated, many thanks
