How do I connect with HDMI cables?

The most traditional way to connect your laptop's screen to your TV is using an HDMI cable. While this approach has the lowest initial cost, but it also creates the most problems.

Most HDMI cables are 6 feet long – and getting longer cables run the risk of signal loss. So either you have to work very close to your large screen display – or string long cables across the room. If you do go this route at home – make sure to use gaffer tape to secure the cables on your floor – otherwise tripping over a cable can pull down either your TV, your laptop – or both. If you are in an office environment, you should hide these cables in the floor or walls so they are properly secured.  

One other drawback of HDMI cables is that it can be hard to connect other devices like your tablet or phone to your TV. Also, in case you have a TV with 4K resolution, it is difficult and expensive to split the screen to show multiple sources with HDMI cables and splitter hardware.

How can I connect laptop to TV wirelessly?

As an alternative, wireless methods of connecting a laptop to a TV are growing in their popularity. There are a lot of benefits to wireless screen mirroring. It enables you to connect to a TV without any cables – from all kinds of different sources. The best ones can split up your 4K TV into different sections so you can have multiple presenters or sources on the screen. 

Imagine if you are a realtor with a home office – you can have one section connected to your notebook showing a listing, a second to your phone showing the Zillow page, third to a tablet running a tour video, and the fourth section to your desktop computer showing MLS comps. More importantly, with the right equipment, you can do this without having to call in an IT expert to get it running. 


Basic wireless connectivity to a TV

One of the least expensive ways to connect a laptop to a TV is with Google Chromecast.  If you have a single Windows laptop, and only occasionally want to connect to your TV, this is is a solid option.   If you are Mac user, then you may want to look at an Apple TV – which works great with a MacBook or an iPad – but won’t connect to your Windows notebooks.

Both these solutions are good for sharing videos or an occasional presentation, but if you are going to use your TV for business or education applications such as a home school, you need something that can provide secure and reliable data transmission.  


Wireless Screen Mirroring to Connect People & Ideas

In the last couple of years, there are many new ways to use your TV to collaborate and share can notebooks, phones, and Blu-Ray players players without compromising security or having to load risky apps on your device. For a classroom, meeting room, or huddle space, you want a system that uses HDMI and/or USB-C buttons to connect a laptop to a TV without an app – and enables encryption so that you don’t have to worry about having your content recorded. These are more expensive than the consumer-oriented solutions but enable neat features such as splitting up a 4K TV screen into four separate sections to see multiple inputs at the same time.
