In short
A pink screen is a light desaturated field in the upper mid-tones, which fills a gap the other eleven leave: uniformity checking above mid grey but below full white. Panels that look even at mid grey sometimes reveal patchiness in the bright tones, and a light tint shows it where pure white does not, because white saturates the eye's brightness perception and hides small variations. Pink is also a comfortable field for a long visual sweep across a large panel, unlike yellow or white at full brightness. It is a reasonable second opinion after grey rather than a first check — if grey looked clean and something still seems off in bright content, this is the field to try. Searches for a pink screen also land on magenta, which is the saturated version and does a different job: magenta is for spotting green sub-pixel faults and red-to-blue tint drift, while this lighter field is for brightness uniformity near the top of the range.

About the Pink Screen
The Pink Screen fills your entire screen with solid pink. A light saturated field for checking uniformity in the upper mid-tones. It runs as plain JavaScript inside the page, which means there is no upload step, no queue and no size limit imposed by a server — the only limit is your own device.
What people use it for

- Using as a plain backdrop for photography or for cleaning the screen.
Press Fullscreen above before judging anything. A colour patch surrounded by page furniture tells you very little — the panel needs to be filling the whole screen, ideally in a dark room, with any night-light or blue-light filter switched off.
Frequently asked questions
What is the difference between a dead and a stuck pixel?
A dead pixel receives no power and stays black on every colour. A stuck pixel is latched on and shows the same bright red, green or blue dot against every background. Stuck pixels sometimes recover; dead ones never do.
How do I tell a dead pixel from dust?
Dust sits on the outside of the glass and moves or disappears when you wipe the screen with a microfibre cloth. A dead pixel does not move and stays in exactly the same position on every colour.
How many dead pixels before I can return a monitor?
That depends on the manufacturer's policy, which is usually written against the ISO 9241-307 pixel fault classes. Most consumer panels are sold to a standard that tolerates several sub-pixel faults, so check the specific warranty terms — and photograph what you find while the panel is still within the return window.
Do I need an account to use the Pink Screen?
There is no cost and no cap. The Pink Screen is not a demo of a paid product, so nothing is held back or watermarked.
Is what I paste into the Pink Screen stored?
No. The Pink Screen runs entirely in your browser using JavaScript. Your input never reaches inputtesthub.com or any third party — open your browser's Network tab while you use it and you will see no request go out.
When would I actually need the Pink Screen?
Typical uses: a light saturated field for checking uniformity in the upper mid-tones. Checking a monitor or phone screen before a return window closes. Using as a plain backdrop for photography or for cleaning the screen. It is built for exactly those cases rather than being a general-purpose tool with this bolted on.
What do people usually get wrong here?
Press Fullscreen above before judging anything. A colour patch surrounded by page furniture tells you very little — the panel needs to be filling the whole screen, ideally in a dark room, with any night-light or blue-light filter switched off.
Do I need to install anything to run this test?
No installation, no extension and no driver. The Pink Screen uses the browser's own device APIs and begins as soon as the page loads, so there is nothing to press first. Press Reset at any point to start over with a clean slate.
