My Computer Won't Connect When the TV has difficulties connecting to a PC, these steps may help resolve the problem. The problem The "Mode Not Supported" message appears. Try this! Set your PC's output resolution so it matches a resolution supported by the TV. The video is OK but there is no audio. If you are using an HDMI connection, check the audio output setting on your PC.
