While the wired connection via an HDMI cable is the easiest way of connecting your laptop’s screen to TV, yet it comes with a fair share of downsides as well. You may have a "MODE NOT SUPPORTED" message on the TV, that will mean that video signal is sent but the resolution is not compatible with the TV's supported ones (1024 x 768 or 1920 x 1080). There is an increasing need of connecting the laptop to a smart TV but without using any cable. If not, you may need to purchase a 7 to 4 pin adapter or select another method below. In some cases, you may need to utilize the fn key and one of the function keys (F3, F4, F5) along the top of the keyboard.

Before you purchase a cable be sure that your laptop and TV use the same S-Video: it could be 4 or 7 pin holes. Once connected, hold down the Windows Key and press P to toggle the selection to the desired setting: Duplicate.

Once that is set, be sure you connect the Laptop to the HDMI1 port on the back of the TV. This is probably the simplest, most widely available connection. My advise is, if you are having a hard time with this is to contact dell for them to guide you on this. Check on the control panel or on the video icon and you will have an option to select the second monitor. Most computer will by default send video signal to the laptops monitor, but other external source (such as VGA or DVI) needs to be enabled and will let you choose between having both working, just the external monitor or extended desktop (where both will show a part of the actual desktop). Welcome to you need to enable that output, that message you are getting is that NO SIGNAL at all is being sent through that connection.
