Hello,

Have used easy driver an updated the graphics driver. Have tried extending. Display settings does not detect another display.

Have spent hours in forums reading various recommendations. Have unplugged all hdmi's to tv and plugged laptop into primary hdmi, still no signal.

Have tried unplugging tv for 10 mins and restarting with only laptop hdmi plugged in, still no signal and does not detect display.

Have been into device manager to search for hdmi port to activate, however hdmi port does not appear in device manager. It works on a computer screen through hdmi, but not on a tv.

Help, frustrated.
