How to Connect Windows 10 Laptop to Projector/TV

Getting a Microsoft Windows 10 laptop connected to a projector or TV can be the most annoying part of getting ready for a presentation. Here’s everything you need to know to get up and running.

Making a Wired Connection

There are so many different types of display ports. So there are many different ways your laptop might connect to a TV or projector.

Technology	Photo	Cable Required
HDMI		Standard HDMI cable. Audio routed.
DisplayPort		DisplayPort to HDMI cable. Audio routed.
Mini HDMI		Mini HDMI to HDMI cable. Audio routed.
VGA		VGA to VGA cable. Audio not routed.
USB/DisplayLink		Adapter allows video through USB to HDMI or VGA.

Connect via any of the methods above and ensure the input selection on the TV or projector is toggled to the input you are using with your laptop.

Laptop Connection Settings

Once connected, hold down the Windows Key and press “P” to toggle the selection to the desired setting:

• Duplicate 
• Extend
• Second screen only

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.

Common Problems

Driver Update Needed

It is common (especially on Lenovo ThinkPad machines) to experience problems connecting your laptop to a TV or projector. If the video is blank on one screen or flashes black or white, an upgrade to the display adapter drivers usually fixes the issue.

There have been some occasions where a BIOS update has fixed a display problem.

To obtain the latest display adapter drivers and BIOS software, visit the website of manufacturer of your laptop. You may also be able to simply Google the “model number of your laptop + display drivers.”

Start With Everything Off

In some cases, you may need to start with both the laptop and projector off. Once you have the proper cable connected, turn the projector on. Once the projector is started, power on the laptop. This order is usually the most successful.
