I have a Latitude E5420 with Windows 7 Professional operating system and a Intel HD Graphics 3000 video card.
My HDTV's do not recognize the laptop when I connect both devices via the HDMI port. Cable is good as it works on several other devices including an other laptop.
I have updated my video driver with the latest available on the Dell website version 9.17.10.3040
I see no settings in my graphics display control panel that allow me to make changes.
Anybody knows what I'm doing wrong?
