how to connect dell laptop to samsung hdtv?

[Snitch]

Connect an HDMI cable.
On the TV open the Inputs Menu and select the HDMI Input you plugged into.
Start the laptop and see if it connects.

On the laptop you can toggle through various combinations having one or both video screens enabled.
Hold the Fn and Tap the F8 and wait a second or 2. Repeat as needed.
If you have the laptop screen off and the TV screen on, it can go to higher resolution.

It may be another Function key to press with the Fn.
Look for the one with an old rounded rectangle CRT Monitor Symbol on it.
