Fixing Resolution of HDMI Output on PC

If you’re using your HDMI-enabled TV or screen as a second monitor on your PC, you may experience issues with the resolution. This can occur when you’re streaming TV shows and watching movies or using it to perform work. For normal use as a monitor, Windows will control the display settings for your HDMI connection. When you’re watching videos, the source application may override the Window settings, leading to inconsistent results. If you face issues with your Windows resolution, this guide will help you with fixing the resolution of the HDMI output on your PC.

Fixing HDMI Resolution Issues

When you experience variations in resolution from your HDMI TV connected to your PC, it could point to a setting on the TV. Depending on the manufacturer, you may have to adjust the picture settings using the menu options. Specifically, there’s a legacy setting on older TVs called “overscan.” This can lead to inappropriate resolutions and screen sizes.

Change the HDTV Settings for PC Use

Overscan is a technology that helped content creators to deliver consistent pictures on a variety of different screen sizes and aspect ratios. As technology improved and manufacturers followed new standards, overscan became obsolete.

If you can’t access or see all the edges of the desktop on the screen, it’s likely that overscan is to blame. To fix it, make sure you change your HDTV’s aspect ratio to the Screen Fit setting in the Picture settings.

Finding the right setting will vary between manufacturers and models. Usually, the setting is available under Picture Settings or Advanced Options. Look for the Aspect Ratio you’re currently using and make sure it is set to Screen Fit whenever you use the HDMI TV as a monitor.

Adjust Aspect Ratio

Some models will have an overscan setting instead of specific aspect ratios. If this is the case, ensure you use the Screen Fit option for the best results or turn off overscan. If you’re unsure about the settings, check the User Manual of your HDMI TV.

How Do I Change the Resolution for My HDMI TV from My PC?

If you’ve changed the Aspect Ratio and the screen now fits on the TV, you may also face issues with the resolution settings on the PC. To change your resolution settings, you’ll need to access your PC’s display options.

  1. Hit the Windows Key and type Change Display Settings. You can then click on the top result.
Open Display Settings
  1. Once the Display Settings App opens, you’ll see two screens (or more if you’ve got multiple HDMI outputs connected). Make sure you select the right display for the HDMI TV before making any changes. You can do this by clicking on Identify.

Note that if you do not have all the different resolutions available you may need to use your Graphics Card’s software to update the resolution.

Changing Resolution Settings in Graphics Card Software

If you want to change your resolution settings, you can use the manufacturer of the graphics card’s software instead of Windows. Depending on your specific set up there will be different methods for changing the resolution. Firstly, depending on how you’ve connected the primary and secondary monitors will determine if you’re using onboard graphics or the installed GPU. On laptops, it’s common to use the onboard graphics for the normal screen, and the HDMI monitor will use the installed GPU.

For a set up that uses both onboard graphics and a GPU, you may need to change the settings for the onboard graphics.
