What is Display Inspect?

Display Inspect is a free, browser-based toolkit for checking any screen - monitors, laptops, phones, TVs, plus OLED and LCD panels. Every test runs locally in your browser: solid colours, gradients, motion patterns and touch grids that you judge with your eyes. No app, no signup. Test visuals stay on your device. Open the right device guide on the screen you want to check, go fullscreen, and spot dead pixels, uneven brightness, backlight bleed, banding, ghosting and more in under a minute. If a printer is the device giving you trouble, our companion site Printer Inspect covers how to test a printer and troubleshoot print problems.

FAQ

Common questions about monitors, laptops, phones, TVs, OLED and LCD

01Which test should I use for a monitor, laptop, phone or TV?

Use the device guides above - Monitor (8 checks), Laptop (7), Phone (7 including touch), TV (8). Each guide orders the exact tests for that panel so you don't have to guess which pattern matters.

02How do I quickly check a new monitor for dead pixels before the return window ends?

Open the Dead Pixel Test on the monitor itself, go fullscreen, and cycle black, white, red, green and blue. Look for dots that never change colour. Do it on the native resolution in a dim room and check the whole panel, including edges.

03Will the same browser test work on iPhone, Android, Windows and Mac?

Yes. Display Inspect runs in Safari, Chrome and other modern browsers with nothing to install. For phones, open the Phone Screen Test on the phone you want to check; for laptops and monitors, open it on that device directly.

04My TV has no browser - how can I still run a TV screen test?

Connect a laptop or streaming stick to the TV's HDMI input and open the TV Screen Test on that input. If you use the TV's built-in browser, open it there directly. Test from your normal couch distance, then step closer for pixel checks.

05Do OLED and LCD need different checks?

Yes. OLED displays can benefit from Burn-in, Black Level and Greyscale checks, including checks for image retention and near-black detail. LCD displays can benefit from Backlight Bleed, Black Level and Uniformity checks; IPS panels may also show viewing-angle-dependent glow. Both types can be checked for pixels, color, brightness and motion.

06My LCD looks cloudy or glows in the corners - is that backlight bleed?

Open a pure black pattern in a dark room. Backlight bleed stays fixed at the same edge or corner when you move; IPS glow shifts or fades as you change viewing angle. The Backlight Bleed Test helps you compare both.

07Do I need to run every test, or will one solid colour be enough?

One colour isn't enough. Dead pixels hide on some backgrounds, bleed only shows on black, banding only on gradients and ghosting only with motion. The device guides run the minimal set that covers all visible defects without repeating the same check.
