One of the things we love most about laptops from the modern era is the ability to plug them into a larger screen like a television. This is an especially useful features if your display measures less than 15-inches, which is the standard size for laptops. And what makes this possible? Why the wonderful HDMI connection of course! If you’ve tried connecting your laptop to a TV and was challenged by stretched out, blurred or otherwise distorted images. This post is for you. Keep reading to find out how to adjust the HDMI screen size on a TV with Windows 10.

What Is HDMI?

A high-definition multimedia interface (HDMI) port and cable are standard for digitally transferring audio and video signals. The signal starts at the source, which is your laptop. Then, it’s transmitted to a video display device, like your TV or any other compatible home entertainment screen.

HDMI cables are both simple and effective. Consequently, they’ve become the go-to transmitters for commercial and corporate markets. This includes education, retail displays, work presentations, and much more!

How to Adjust HDMI Screen Size for Your Laptop to TV Connection

Now that we know how HDMI cables work and why they’re important, let’s see how they can help us adjust the TV screen size.

So, you want to display the content from your Windows 10 laptop on the TV screen. Maybe you’re getting ready for a get-together with friends to watch movies.

Or your kids have their friends over to play PC games and enjoy the latest superhero action movie.

Whatever the reason, it’s much better to enjoy it on a large TV screen rather than a small one. Plus, the solution is simple enough: all you need is an HDMI cable, plug the ends into both devices, and you’re all set!

Pretty simple, except the problem is that, sometimes, things aren’t always that straightforward. This is why we rounded up a user-friendly guide on adjusting the HDMI screen size on your TV.

Let’s get started.

Step 1: Connect the Devices

Just to make sure we cover all the bases, you’re going to make sure that the TV has a small, flat HDMI port. It could be located either on the left or right side of the display, somewhat hidden behind the big screen.

Next, plug the cable into the TV display. Then, attach the other end to the laptop’s HDMI port.

This is a good time to remind you to make sure the laptop battery is fully charged. To avoid the batter dying halfway through, keep it plugged into a power outlet as a precaution.

It’s important to mention that HDMI cables are usually the same on both sides. In other words, it doesn’t matter which end connects to what device. So, thankfully, that’s one less thing you have to worry about.

Step 2: Turn on the TV

The next step is to plug in the TV and turn it on.

If the TV has more than one HDMI port, make sure you select the one that matches the laptop connection. To do this, toggle through the HDMI source options on your television until the image on the monitor appears on the TV screen.

Step 3: Modify the Monitor Display

Now, it’s time to set the display setting on your laptop to match the TV display settings. The good news is that it doesn’t matter whether you’re using a laptop or a traditional desktop computer. As long as it’s operating via Windows 10, everything should run smoothly.

To configure the display in Windows 10, do the following:

  1. Click on the ‘Start’ menu and choose ‘Settings’ or type ‘Settings in the search bar.
  2. Click on ‘System’.
  3. Click on ‘Display’ settings.
  4. Under the ‘Scale and Layout’ section, fix the size of the text to fit in the screen.
  5. If it’s still blurry, click ‘Advanced scaling settings’ then ‘custom scaling’ to get it just right.
  6. Next, scroll down and you’ll see a display resolution dropdown menu.
  7. Pick the resolution that best matches that of your TV model.
  8. Scroll down more until you get to the ‘Multiple Displays’ section.
  9. The default setting under ‘Multiple Displays’ gives you the option to duplicate or mirror your laptop.
  10. Finally, click on ‘Extend These Displays’ to extend the Windows 10 desktop onto the TV.

Step 4: Adjust the TV Resolution

Before we go on, it’s important to check the resolution of your TV. You can confirm this by looking at the user guide, or you can check the ‘Display Setting’ on your TV.

TV Resolution

So, what is a TV resolution anyway? Resolution is a screen’s physical size, measured in pixels. Millions of pixels join to create the seemingly flawless image you see on your TV screen.

There’s no doubt that pixels and resolutions are among the most sought out features of modern-day TV sets. After all, who can resist a 4K Ultra High-Definition screen? It sounds so high-tech, doesn’t it?

Nonetheless, a higher resolution doesn’t necessarily mean better images. For that to happen, the resolution has to go hand-in-hand with other features, such as a high dynamic range and contrast ratio.

That said, TV resolutions are still an important feature that matches the laptop display. Configuring the correct TV resolution ensures an ideal fit of the image on the TV screen.

To avoid getting into too much unnecessary detail, we decided to keep things simple. It’s why we’ll only be focusing on the two main basic types of TV resolutions available in most homes. Of course, they’re the only two that matter when adjusting the HDMI screen size on a TV anyway.

Types of TV Resolutions

Most TVs come in the following resolutions:

  • FHD TV: 1920 x 1080 resolutions (1080p)
  • HD TV: 1280 x 720 resolutions (720p)

Suppose the TV and laptop screen resolutions match, then great! You can leave them just as they are.

On the other hand, if they’re different, you’ll have to do a bit of tweaking until you get the image looking just right.

Bear in mind that most laptops and computers these days support a full HD (FHD) resolution: 1920 x 1080. This is the ideal resolution to make sure the screen size is a perfect fit. If that’s not available, the next best option would be 1366 x 768 pixels, which best suits TVs with resolutions of 1280 x 720.

So, what happens if your laptop or computer doesn’t feature this resolution? In that scenario, you’ll have to go through each resolution type until you get the best possible image on the TV screen.

Another option is to check your TV manual. It should provide you with the information you need to tell you which resolution works best for your TV model. Plus, you’ll save time going through each resolution looking for the best fit between your laptop and television.

Step 5: Check the Aspect Ratio

The last step in adjusting the HDMI screen size is to make sure the aspect ratio for both the TV and the laptop is in sync. This ratio is the measurement between the width and height of any display screen.

Typical HDTVs have a default aspect ratio of 16:9. The first number denotes the width of the image, whereas the second tells us its height.

This ensures that the image fills up the screen with no horizontal black bars running on the top and bottom of the display. Those bars usually appear if your TV is in a 4:3 aspect ratio.

That ratio was the standard size for older TV sets before the advent of widescreens. Nowadays, however, they’re no longer as predominant as they once were.

To adjust the HDMI screen size, you’ll also need to know the aspect ratio of your laptop. You can do that by finding out your laptop’s resolution. Here are the most common resolutions and their aspect ratios:

  • 1920 x 1080 = 16:9
  • 2560 x 1440 = 16:9
  • 1366 x 768 = 16:9
  • 1280 x 800 = 16:10
  • 1440 x 900 = 16:10
