To fix a black spot on your laptop screen, gently clean the surface, compare the mark across solid colors and a screenshot, then arrange repair if hardware checks confirm display damage. Surface dirt and software artifacts need different fixes from failed pixels or a cracked panel. A persistent physical black spot cannot be repaired by changing display settings.
The short version
- Clean first: Shut down your laptop and gently remove surface dirt before diagnosing the display.
- Compare images: View a screenshot on another functioning display to help separate rendered content from a physical screen problem.
- Test the hardware: Built-in display diagnostics can show whether the mark persists independently of the operating system.
- Follow the evidence: Use software fixes for software artifacts and arrange service for confirmed panel damage.

Clean the screen gently
Save your work, shut down the laptop, and disconnect its power adapter before cleaning. Dell also recommends disconnecting peripherals and gently cleaning the screen with a soft cloth before running display diagnostics. Recheck the mark afterward, because a removable surface smudge needs no further troubleshooting.
For a MacBook, use a soft, lint-free cloth dampened with water and gently wipe the display. Apple permits a cloth moistened with 70-percent isopropyl alcohol for stubborn smudges, but apply liquid to the cloth, never directly onto the screen. A nano-texture display requires its separate model-specific cleaning instructions.
Do not press or massage the spot to try to restore it. Dell advises against screen-pressure methods and pixel-fixing software, and says dead pixels require panel replacement. If gentle cleaning leaves the mark unchanged, check whether it comes from displayed content or the screen hardware.
Examine the mark against solid colors
A tiny fixed dark dot, a broad uneven patch, and a retained image pattern need different next steps. Open the EIZO Monitor Test, select Select none, then select Defective Pixels and Uniformity. Select Start test to begin.
Use the Left Arrow and Right Arrow keys to move through the test screens, inspecting black, white, red, green, blue, and gray backgrounds. Look for missing pixels that stay in one place versus larger areas of uneven brightness, then press Esc to exit. This test helps you describe the defect; it does not repair pixels.
A black area with jagged lines that remains during startup needs hardware assessment for possible LCD damage. HP says settings cannot correct a cracked LCD. If hardware assessment establishes physical damage, skip driver changes and operating-system resets and arrange display service.
Compare a screenshot on another display
Capture the area containing the mark, then open the saved image on another functioning screen. You can take a screenshot on your device using its built-in capture tools. Viewing the capture only on the affected screen cannot reliably separate a physical mark from the captured content.
On Windows 11, press Windows + Shift + S, select the affected area, and save the capture. On a Mac, press Shift + Command + 3 to capture the screen. On a Chromebook with a Show windows key, press Ctrl + Show windows.
If the mark appears in the saved image on another functioning display, you can infer that it comes from rendered content, such as an app artifact. A physical panel defect ordinarily will not appear in a screenshot, but a clean capture does not identify which display component failed. Treat the result as a clue and use an external monitor or hardware diagnostic to narrow it further.
Compare the same content on an external monitor
Connect a known-good monitor using a compatible cable or adapter. On Windows, press Windows + P and select Duplicate so both screens show the same content. Compare the exact area where the black mark appears.
On a Mac, open the Apple menu > System Settings > Displays, select the connected display, and open Use as to choose mirroring. On a Chromebook, select the time, open Settings > Device > Displays, then select Mirror built-in display. That Chromebook option appears after a monitor is connected.
A clean external image suggests a problem in the laptop's internal display path. It does not conclusively separate the panel from its cable or other hardware, so do not order a replacement panel from this result alone. An external monitor can provide a temporary workaround while you arrange assessment.
Run the hardware check for your laptop
Built-in diagnostics can check hardware independently of normal operating-system use. Follow only the procedure for your laptop brand and supported model. If the spot persists during a display check, seek hardware assessment before spending more time changing apps and settings.
For a Dell laptop with LCD self-test support, shut down, disconnect external devices, and connect the charger. Hold D, press Power, and release D when colors appear. Inspect each color for the spot and press Esc to stop; the test checks hardware and does not repair pixels.
Selected Lenovo ThinkPad, Lenovo Notebook, and ThinkBook models support an LCD self-test, so check your model's compatibility first. Turn off the laptop, connect its AC adapter, and press Fn + Left Ctrl + Power simultaneously. Inspect the sequence of at least five solid colors; the test takes approximately 20 seconds, and pressing Power exits sooner.
On a supported HP notebook, shut down, power on, and repeatedly press Esc about once per second. At the startup menu, press F2, then select Component Tests > Video > Palette Check > Run once. Available tests depend on the hardware.
For Apple silicon Macs, shut down and disconnect unnecessary accessories, then hold Power until Options appears. Release Power and hold Command + D to start Apple Diagnostics. Select Run Offline if offered, choose the built-in-display diagnostic when offered, and record the results.
For an Intel Mac, shut down and disconnect unnecessary accessories, then turn it on while holding D; try Option + D if needed. Follow the available diagnostic prompts and record the results. Component-specific checks depend on the macOS version; earlier versions run diagnostics automatically.
On an ASUS notebook, start from power off, hold F2, and press Power to enter BIOS setup. Release F2 when setup appears and inspect the mark without changing settings. ASUS recommends hardware assessment when the abnormal display persists there.
Use software fixes when the mark follows content
Use software troubleshooting when the mark appears in a screenshot or follows an app, provided hardware checks have not established physical damage. On Windows 11, press Windows + Ctrl + Shift + B to reset the graphics driver. If the artifact remains, save your work and restart; follow the steps to restart an unresponsive computer if normal controls do not respond.
For an artifact that began after a graphics-driver update, right-click Start and open Device Manager. Expand Display adapters, right-click the adapter, then select Properties > Driver > Roll Back Driver. Choose the applicable reason, select Yes, and restart. You need administrator permissions, and an unavailable rollback button means Windows has no previous package to restore.
If rollback is unavailable or does not apply, open Settings > Windows Update and select Check for updates. Open Advanced options > Optional updates, select an applicable graphics-driver update, and select Download and install. Restart after installation and compare the same content again.
Mac graphics software updates come with macOS. Back up your Mac, then open the Apple menu > System Settings > General > Software Update and install the compatible update offered. Enter the administrator password if requested, and keep the Mac powered while installation finishes.
For a Chrome-only artifact, open More > Extensions > Manage extensions, turn off suspected extensions, and retest. If you identify a responsible extension, select Remove, then select Remove again to uninstall it. If a managed extension cannot be changed, contact your administrator.
For Firefox, close the browser and hold Shift on Windows or Option on macOS while launching it, then select Open to enter Troubleshoot Mode. This temporarily disables extensions, custom themes, and hardware acceleration. If the artifact disappears, those components need further isolation; if it remains, the mode has not identified the cause.
Black borders around a smaller desktop need a resolution check. In Windows, open Settings > System > Display, select the built-in display, and choose the Display resolution marked (Recommended). When unclear text accompanies the sizing problem, follow the steps to fix a blurry computer screen.
If a software artifact persists after the relevant steps, give your laptop maker the screenshot comparison and diagnostic results for further troubleshooting. If the mark also appears during hardware display checks, return to hardware assessment. Reinstalling the operating system cannot repair established panel damage.
Check ASUS OLED dimming and retained images
Supported ASUS OLED laptops can deliberately darken inactive areas through Target Mode. When the darkening follows active and inactive windows, open MyASUS > Device Settings > Audio & Visual and turn off Target Mode. Compare the windows again before treating that behavior as panel damage.
For a retained image pattern, ASUS recommends turning the affected OLED display off for at least one hour and says a full day may be better. Recheck afterward and contact ASUS support if the pattern persists. This rest period does not repair a cracked panel or an established dead pixel.
On selected models, open MyASUS > Device Settings > Audio & Visual > ASUS OLED Care and enable Pixel refresh and Pixel shift where available. Pixel refresh starts a special screensaver after 30 idle minutes, while Pixel shift slightly moves displayed content. These are maintenance features, not repairs for dead pixels or a cracked panel.
Arrange service for a persistent physical spot
When a black dot or patch remains after cleaning and hardware checks point to a display fault, photograph it and record the diagnostic results. Provide those details when requesting service so the repair provider can assess the panel and other display hardware. Confirmed dead pixels or cracked LCD damage require the appropriate display replacement.
Use an authorized repair center for an HP display assessed as cracked, or contact your laptop maker for its repair route. A compatible external monitor can provide a temporary workaround if it displays content correctly. Repair eligibility depends on the diagnosis and applicable coverage, so request an assessment before buying replacement parts.
Frequently Asked Questions
Will the warranty cover one black pixel on a laptop screen?
One black pixel does not automatically qualify for warranty replacement. Dell's laptop pixel policy permits up to five dark subpixel defects, and eligibility also depends on defect type, resolution, warranty, and damage coverage. Count and photograph the defects, then ask Dell to assess coverage using your Service Tag.
Can dirt get trapped inside a MacBook display?
Material can be trapped inside an LCD display and remain after surface cleaning. Apple assigns removal of internal display material to an Apple Authorized Service Provider or Apple Retail Store. Arrange an examination if gentle surface cleaning does not remove the mark.
Can JScreenFix repair a black spot?
JScreenFix offers its tool for bright stuck pixels, not black hardware failures. That is a different symptom from a persistent dark dot or black patch. Dell advises against pixel-fixing software, so do not substitute it for hardware assessment.
Should you try a Chromebook hardware reset?
A hardware reset is an option for a suspected transient hardware-state fault after simpler troubleshooting fails, but it cannot repair a physically damaged panel. For most Chromebook laptops, turn the device off, hold Refresh, tap Power, and release Refresh when it starts. Google warns that this might delete files in Downloads, and some models require a different procedure.
Can you replace a MacBook display yourself?
Apple offers Self Service Repair for eligible Mac models and countries, intended for people experienced in electronics repair. Select your exact model's repair manual and check its required parts, tools, and manual ID before ordering through the authorized store. Follow the model-specific replacement procedure and complete any postrepair software steps the manual specifies.
