Laptop to tv with hdmi; no signal

[fixincyn]

Hello,
I have a dell e1505 laptop with a newer hard drive but I had to do a reinstall recently. Do I need some sort of driver to show it on the tv?

Did it used to work before you did a reinstall?

Try going to Dell's site and download the most recent video drivers for it.

You will need to reinstall your video driver and check your resolution settings.
