Laptops are great for moving your "office" around the house, but sometimes you want or need a little more on-screen real estate. Connecting a larger external monitor to your laptop can more than double your screen size, as well as let you multitask like a pro. Here's how to make it happen.

1. Choose the right port and cable

Most laptops have at least one port you can use to connect a monitor. However, not all ports deliver the same quality video and features. Here's how to choose the right one for you.

HDMI and DisplayPort

HDMI and DisplayPort

For most people, the best options are HDMI and DisplayPort. Both send audio and video signals over one cable, which makes them an easy way to connect a laptop to a monitor. DisplayPort has the additional benefit of being able to connect more than one monitor to a laptop. DisplayPort is also a better option for gamers with laptops that have high-end graphics cards with AMD's FreeSync and NVIDIA's G-Sync technology.

Some laptops have USB-C port that can also function as a DisplayPort port. Check the specs of your laptop to verify compatibility with DisplayPort.

You can buy an HDMI to DisplayPort adapter, though you will only be able to access the HDMI features.

If you're buying an HDMI cable and have a 4K monitor, get a cable that is certified Premium High Speed HDMI (yes, that is a thing). We like the Monoprice cables (starting at $4.93 on Monoprice, check price on Amazon). Older HDMI cables will work, but they may not deliver the full depth of color and resolution.

VGA and DVI

VGA and DVI

If you have an older laptop or monitor, it will likely have a VGA port or a DVI port for connecting to a second screen. VGA supports standard definition video (640 x 480), while DVI can send a signal at up to Full HD (1920 x 1080). Neither sends audio. If you want to play audio on your monitor, you will have to plug in a cable from your computer's headphone jack to the audio input on your monitor.  

If you have an older laptop, you can buy a DVI or VGA adapter to plug into an HDMI or DisplayPort input on your monitor. However, the quality of the video will be limited to standard definition for VGA or high definition for DVI and you'll still have to run a separate audio cable.

2. Connect your monitor

Connect the monitor to your laptop with a cable and then turn on your monitor. Windows should detect the monitor and display what's on your laptop screen. If this doesn't happen, make sure the monitor is set to the correct input. You may have to scroll through the inputs to find the correct video input, HDMI, DisplayPort, etc. If you're still not seeing an image on your monitor, you'll need to head into Windows Display Settings by clicking Start > Settings > System > Display and click on "Detect" to get your laptop to recognize the monitor.

3. Choose what you see on your monitor

When you connect your monitor, you can choose what appears on the screen. Here are your options.

Windows 10 external monitor options

Show the same output on your laptop and monitor

Windows defaults to "Duplicate these displays." So, what you see your laptop screen is what you see on your monitor, and when you move your mouse on one screen, it will also move on the other. In this mode, your monitor may not receive a full resolution signal if your laptop graphics card is not powerful enough to deliver the full resolution to both displays.

Show output only on the external monitor

If you want to use only the external monitor, choose "Show only on 2." This will ensure your monitor receives the highest resolution from your laptop, and you can work with your laptop closed. (Selecting "show only on 1" will make your laptop screen your only display.)

If you want to close your laptop while using your monitor, you'll need to make sure the computer doesn't go to sleep when you close the lid. Go to Start > Settings > System > Power & Sleep and select “Additional power settings.” A new window will open. Select "Choose what closing the lid does." Select "Do nothing" in the drop-downs for when the laptop is "on battery" and "plugged in" so your laptop won't go to sleep.

What happens with the lids closes

Spread your desktop across your laptop and monitor

You can show different content on your laptop and monitor by selecting "Extend these displays." In this mode, you can move your mouse beyond the edge of one screen to enter the other. This also lets you drag and drop windows onto both displays. So, you could have one program open full-screen on your laptop display and another on your monitor.

4. Optimize the size of your text and app icons

Change text size

You might find that the text and images appear too small. To correct this, use the "Change the size of text, apps, and other items" button to make sure you can easily read what's on the screen. Windows will recommend a setting between 150-250 percent, but you can play around with it and see what works best for you.

VGA high resolution

From Bob on July 29, 2020 :: 9:44 am

A very good guide overall, but, almost any laptop that’s new enough to still be viable will achieve 1920 x 1080 through its VGA port. I have connected many monitors to VGA ports at 1920 x 1080. smile
