Simply search for “System Information” in the Windows search bar and open the application. Navigate to “Components” and then “Display.” The adapter description will identify your graphics card.
Accessing the Graphics Control Panel
Once you know your graphics card manufacturer, you can access the corresponding control panel. The method for opening each differs slightly.
For Intel graphics, you typically have the Intel Graphics Command Center (newer systems) or the Intel Graphics Control Panel (older systems). To open the Intel Graphics Command Center, search for it in the Windows search bar. Alternatively, right-click on the desktop and look for “Intel Graphics Settings” or “Intel Graphics Command Center” in the context menu.
For NVIDIA graphics, right-click on the desktop and select “NVIDIA Control Panel.” You can also find it in the system tray (the area in the bottom-right corner of the screen).
For AMD graphics, right-click on the desktop and select “AMD Radeon Settings” or “AMD Radeon Adrenalin Software,” depending on the version of the software installed. It may also be located in the system tray.

Key Sections Relevant to HDMI
Each graphics control panel has different sections, but the most important ones for managing your HDMI laptop connection are those related to display settings, resolution, refresh rate, color settings, scaling, and audio output. Familiarize yourself with the layout of your specific control panel, paying close attention to these sections. Look for options such as “Display,” “Resolution,” “Refresh Rate,” “Color Settings,” “Scaling,” “Multiple Displays,” and “Audio.” These are the areas where you will make adjustments to optimize your HDMI output.
Configuring HDMI Output Settings
Now that you know how to access your graphics control panel and are familiar with the relevant sections, you can begin configuring your HDMI output settings for optimal performance.
Resolution and Refresh Rate
Resolution refers to the number of pixels that make up the image on your external display. Higher resolutions, such as 1920×1080 (1080p), 2560×1440 (1440p), and 3840×2160 (4K), provide sharper and more detailed images. Refresh rate, measured in Hertz (Hz), indicates how many times per second the image on the screen is updated. Higher refresh rates, such as 120Hz or 144Hz, result in smoother motion, particularly noticeable in fast-paced games and videos.
To select the correct resolution for your external display, navigate to the display settings section in your graphics control panel. Choose the resolution that matches the native resolution of your external display. The native resolution is the resolution the display was designed to operate at. If you select a lower resolution, the image may appear blurry or stretched. Choose the optimal refresh rate based on the capabilities of your external display and HDMI cable. Standard HDMI cables typically support up to 60Hz at 1080p or 1440p, while newer HDMI versions, like HDMI 2.0 and 2.1, are required for higher refresh rates at 4K resolution. Selecting an unsupported resolution or refresh rate can lead to issues like a blank screen or flickering.
Display Modes
Your graphics control panel allows you to choose between different display modes: clone, extend, and single display. Clone, or duplicate, mode mirrors the laptop screen on the external display. This is useful for presentations or when you want to share the same content on both screens. Extend mode treats the external display as an extension of your laptop screen, allowing you to spread your desktop across both displays. This is ideal for multitasking and increasing your workspace. Single display mode disables the laptop screen and only uses the external display. This can be useful for maximizing performance or when the laptop screen is damaged.
To switch between display modes, navigate to the “Multiple Displays” section of your graphics control panel. You will typically see options to “Duplicate these displays,” “Extend these displays,” or “Show only on [Display Number].” Select the desired mode.
Scaling and Aspect Ratio
Scaling refers to how the image is displayed on the external display when the resolution doesn’t perfectly match the display’s native resolution. Common scaling options include maintaining aspect ratio, full screen, and no scaling. Maintaining aspect ratio preserves the original proportions of the image, which may result in black bars on the sides or top and bottom of the screen. Full screen stretches the image to fill the entire display, which can cause distortion if the aspect ratio is not correct. No scaling displays the image at its original size, which may result in a smaller image with black borders.
To adjust scaling, navigate to the “Display” or “Scaling” section of your graphics control panel. Experiment with the different scaling options to find the one that provides the best image quality without distortion or black bars. Some applications may have their own scaling settings that override the global settings in the graphics control panel. If you are experiencing scaling issues with a particular application, look for scaling options within the application’s settings.
Color Settings
The graphics control panel allows you to fine-tune the color settings of your HDMI output, including brightness, contrast, gamma, and color temperature. Adjusting these settings can improve the image quality and make it more pleasing to your eyes. Color profiles are pre-defined sets of color settings that are optimized for specific types of displays or content. Selecting the appropriate color profile can improve color accuracy and vibrancy.
To adjust color settings, navigate to the “Color Settings” section of your graphics control panel. Experiment with the different settings to find the ones that provide the best image quality for your external display and viewing environment. HDR (High Dynamic Range) is a technology that expands the range of colors and contrast that can be displayed, resulting in a more realistic and immersive image. If both your laptop and external display support HDR, you can enable it in the graphics control panel.

Even with proper configuration, you may encounter issues with your HDMI connection. Here are some common problems and their solutions.
No Signal or Display Not Detected
If you are not getting a signal on your external display, or the display is not being detected by your laptop, first check the HDMI cable and connections. Make sure the cable is securely plugged into both the laptop and the external display. Try a different HDMI port on both devices, as one port may be faulty. Update your graphics drivers to the latest version, as outdated drivers can cause compatibility issues. Check if the external display is set to the correct input source (e.g., HDMI 1, HDMI 2). If the display is still not detected, try forcing detection in the graphics control panel. In the “Multiple Displays” section, look for a button that says “Detect” or “Identify.”
Resolution or Scaling Problems
If the resolution is incorrect, or the image is not scaling properly, double-check your resolution and refresh rate settings in the graphics control panel. Experiment with different scaling options to find the one that provides the best image quality. Updating your graphics drivers can also resolve resolution and scaling issues. Ensure the monitor is running on its native resolution for the best image quality.
Audio Issues
If you are not getting sound through your external display, or the audio is being routed to the wrong output, select the HDMI output as the default audio device in the Windows sound settings. Right-click on the sound icon in the system tray and select “Open Sound settings.” In the “Output” section, choose your HDMI display as the output device. Check the volume levels on both your laptop and the external display to ensure they are not muted or too low. Updating your audio drivers can also resolve audio issues. Some graphics control panels may have additional audio settings specific to HDMI output.
Driver Issues
