Dell recommends ensuring that the device drivers and BIOS are up to date using the SupportAssist application for optimal video performance and to help resolve common video-related issues.

NOTE: When SupportAssist does not show up in the search results, go to the SupportAssist for PCs and tablets page for information about downloading and installing SupportAssist.

To learn how to manually download and install a device driver such as Chipset, Video card (GPU), and Monitor driver (if required, most monitor drivers are delivered automatically through Windows Update) on your Dell computer, see the Dell knowledge base article How to Download and Install Dell Drivers.

We must verify whether the problem is the display screen of the laptop, video card (GPU), or video settings on the computer. A straightforward way to identify this is to connect the laptop to an external monitor or TV.

If the issue persists on the external monitor, it may be an issue with the video card (GPU) or video settings and not the laptop LCD panel. Go to verify display or video issues in Windows Safe Mode. Otherwise, go to the next step.

Performance issues may occur if there is any damage to the LCD screen. The display may stop working, work intermittently, flicker, display horizontal or vertical lines, and so on, if there is damage to the display screen.

If you notice a physical damage, contact Dell Technical Support to learn more about repair options that are available in your region. If there is no damage, go to the next step.

Dell laptops have integrated diagnostic tools that can determine if the screen abnormality is an inherent problem with the LCD screen of the Dell laptop or with the video card (GPU) and computer settings.

When you notice screen abnormalities like flickering, distortion, clarity issues, fuzzy or blurry images, horizontal or vertical lines, color fade, running a diagnostic test on the LCD helps identify if the issue is with the LCD panel.

Press and hold the D key and turn on the computer to enter the LCD built-in self-test (BIST) mode. Continue to hold the D key until you see the entire screen change colors.

If you do not detect any screen abnormalities in the integrated self-test mode, the LCD panel of the laptop is functioning properly. Go to the Update the video card (GPU) driver, monitor driver, and BIOS section.

If you notice any abnormalities in the LCD built-in self-test mode, contact Dell Technical Support to learn more about repair options that are available in your region.

Windows Safe Mode does not load any drivers, startup applications, third-party services. This will help us identify if the issue is related to the operating system, video settings, device drivers, or third-party software. To learn how to boot your computer into Safe Mode, see the Dell knowledge base article below based on the operating system that is installed on the computer:

Windows updates can support your Windows operating system in many ways. Windows updates can solve specific problems, provide security patches and protection from malicious attacks, or even add new features to the operating system.

Display settings like brightness, refresh rate, resolution, and power management may affect the performance of the LCD screen on your Dell laptop. Changing or adjusting the display settings can help resolve several types of video issues.

NOTE: Depending on the model of the Dell laptop, the shortcut keys to adjust or change the brightness may differ. See the User Guide or User Manual of your Dell laptop for model-specific information.

If you find that the Dell laptop is unresponsive to touch, touch stops working entirely, or other touch-related issues, you can try some common troubleshooting steps to help fix the touch-related issue.

System Restore is an integrated Windows tool that is designed to protect and repair the operating system. When something goes wrong with your computer, System Restore must be used before you try to restore the operating system to factory default settings.

If the diagnostic tests on the LCD panel and the video card (GPU) passed, it is most definitely an issue that is related to software that is installed on the computer. If the above troubleshooting steps did not resolve the issue, you may try to restore the computer to factory default settings as a last resort.

WARNING: Restoring or resetting the computer to factory default settings will erase all personal data on the computer. Back up all important data like documents, images, music files, spreadsheets, videos to an external hard drive or a cloud-based backup like Microsoft OneDrive.

Dell computers are built with a small amount of hard disk space that is reserved for reinstalling the operating system. This method is the easiest way to restore the computer to factory condition. The restoration process deletes all user data from the computer, so be sure to back up all your files before starting this process.

Who this is for: A dual-monitor setup is usually the best option if you want to have a bunch of app windows open at once. But an ultrawide model might be a better choice if you need a ton of unbroken horizontal space, or you don’t want monitor bezels in between windows.

Why we like it: The Dell P3421W has a sturdy adjustable stand, lots of ports (including a USB-C port that can handle power, display, and data over a single cable), and a three-year warranty. And it has a built-in KVM switch that allows you to easily swap your keyboard, mouse, and video between two computers. The 1440p display has a 60 Hz refresh rate, which is great for typical office work, web browsing, and casual gaming.

Flaws but not dealbreakers: If you use your display in direct sunlight, this monitor might not be bright enough for you. It can also provide 65 W of power over USB-C, but some laptops require more. If you have a laptop with an Nvidia GeForce RTX GPU or an Intel Core i7 processor, you might need to keep the laptop plugged in to a separate charger or use a Thunderbolt dock that can provide the extra power.

Most ultrawide monitors are also curved. This design helps minimize viewing-angle problems—when you’re sitting centered, things on the far edges of the screen won’t look as washed out as they would on a flat display of a similar width. But this also makes ultrawide monitors inaccurate for precision tasks requiring straight lines, such as drawing, photo editing, or similar design work.

The best portable monitor we"ve tested is the ASUS ProArt PA148CTV. It"s an okay choice if you want to use it for productivity and office work, but like most portable monitors, it doesn"t give you the same picture quality as a desktop monitor. However, it"s still good enough overall to have as a second display for your laptop. With a 1080p resolution and 14-inch screen, there"s enough space to see a full window, and the text clarity is excellent due to the high pixel density. It also has excellent accuracy before calibration, which is better than most portable monitors and good enough if your work requires accurate colors.

It"s a well-built monitor with a kickstand to adjust the angle of the screen. Connecting to it is easy as it has two USB-C ports that each support DisplayPort Alt Mode, and it even has a Micro-HDMI input which is ideal if your laptop doesn"t support USB-C. It also has a touch screen, but unfortunately, it isn"t that useful because it doesn"t feel responsive and doesn"t work with macOS devices.
