Full-screen white, black and grey, then the three colours. Note what you see, on which colours, and whether it changes with pressure or lid angle. Then answer the questions on the home page, or pick the matching symptom from the list below.

What it is

Acer laptop screen problems fall into a short list, and each one has its own page: a black or white spot (pixels, pressure, backlight), a line (panel connector, cable, or graphics), a colour cast (settings or panel ageing), flicker (settings, cable, or connector), burn-in ghosts (OLED ageing), a blurry image (settings), half the screen blank (panel driver), or touch that stops responding in one area (digitiser). Run the full-screen colours and use the three questions below to land on the right one. Acer Aspire and Nitro panels are inexpensive TN or IPS parts; a panel swap at an independent shop is usually cheap, and the display cable fault is common on Aspire 3 and 5.

Can it be fixed?

Settings and software faults: yes. Cables and connectors: usually, as a small repair. Panel faults: replacement. The pages linked below say which is which for each symptom.

Warranty

Most makers replace a panel under warranty for physical panel faults that are not accidental damage; pressure marks, cracks and liquid damage are treated as accidental and are not covered. For dead pixels, each brand has a threshold (typically 3–5 bright or 5–8 dark pixels on a laptop; Dell's premium-panel guarantee replaces at one bright pixel).

Every laptop symptom

Why is my laptop screen green?A green tint over the whole screen — or a screen that is entirely green — almost always means one colour channel is missing or one is stuck on, and that is a signal problem, not a panel defect: the display cable through the hinge has worked loose or a pin has failed, a graphics driver has misconfigured the colour output, or a colour filter (Night Light, a colour profile, a screen-reader filter) is on.Fixable Lenovo laptop display issuesLenovo laptop screen problems fall into a short list, and each one has its own page: a black or white spot (pixels, pressure, backlight), a line (panel connector, cable, or graphics), a colour cast (settings or panel ageing), flicker (settings, cable, or connector), burn-in ghosts (OLED ageing), a blurry image (settings), half the screen blank (panel driver), or touch that stops responding in one area (digitiser).Depends — see test Laptop screen issuesLaptop screen problems fall into a short list, and each one has its own page: a black or white spot (pixels, pressure, backlight), a line (panel connector, cable, or graphics), a colour cast (settings or panel ageing), flicker (settings, cable, or connector), burn-in ghosts (OLED ageing), a blurry image (settings), half the screen blank (panel driver), or touch that stops responding in one area (digitiser).Depends — see test Laptop screen green tintA laptop screen that has gone green all over is the signal or the panel's colour balance, and it is usually the signal.Fixable White spot on Lenovo laptop screenOn Lenovo ThinkPad and IdeaPad screens this is a known pattern: a bright, soft-edged white spot that shows on dark backgrounds, most often near the lower half of the screen.Fixable Green dots on laptop screenGreen dotss on a laptop screen are single green sub-pixels stuck on, or a small area where pressure has damaged the OLED layer.Depends — see test Laptop screen purpleA laptop screen that has gone purple all over is the signal or the panel's colour balance, and it is usually the signal.Fixable Dell screen problemDell screen problems fall into a short list, and each one has its own page: a black or white spot (pixels, pressure, backlight), a line (panel connector, cable, or graphics), a colour cast (settings or panel ageing), flicker (settings, cable, or connector), burn-in ghosts (OLED ageing), a blurry image (settings), half the screen blank (panel driver), or touch that stops responding in one area (digitiser).Depends — see test Patches on laptop screenLight or dark patches — cloudy areas, often called mura or clouding — come from uneven pressure on the panel or the backlight diffuser: the lid was pressed or twisted, the laptop was carried under weight, or the panel warped from heat.Not fixable — new panel Lines on laptop screen HPA line on an HP laptop screen comes from one of three places, and the test tells them apart.Depends — see test Laptop screen bleedingBacklight bleed is light leaking around the edges or corners of the screen, visible on a black screen in a dark room as brighter patches.Depends — see test Laptop screen half shadedHalf of a laptop screen shaded or dim — split top/bottom or left/right with a clean edge — is the panel's driver or its ribbon connector: half the rows or half the columns are not being driven.Depends — see test
