Works with VGA connection. HDMI connection is not working with anything. I saw a video on youtube where they opened a laptop and soldered a plug back into working again. Would be nice if there were software that could check a HDMI plug.
Did you try to re-install the video card drivers?
If nothing works with HDMI on the laptop, you can use the VGA port and the headphone jack for audio to connect to the TV.
