Pure Black Screen
A pure black screen is useful for more than just testing your monitor. You can also use it to identify malfunctioning pixels on your display screen.
If you’re looking for a simple way to test your display screen, the most effective tool is this one. This isn’t a regular test screen; this is actually a specially formatted tool that forces your monitor to display a pure black screen.

Online Black Screen Test
Normally, your computer or mobile device uses a color profile (or look-up table) to map color values from an application or image to the actual display.
This allows your device to produce a wider range of colors than it could otherwise, and this is also what makes matching colors between devices so difficult.
However, when you use this tool, your device skips its color profile entirely and instead displays the raw RGB values it receives from this tool.
This produces an accurate representation of black on your screen. It’s just like using an all-black paintbrush with no “color” applied — your screen renders whatever color is underneath it — which is often different depending on where you are on the screen.

FAQs
Fortunately, many monitors have an “Auto” or “Reset” button, which will attempt to automatically adjust these settings for you or reset them to default settings. Otherwise, you can try adjusting the RGB color setting of your display screen. Feel free to play with them until you achieve your goal.
Besides testing your display for malfunctioning pixels, a pure black display screen is useful for testing how well your monitor can display deeper blacks and dark tones. You may not be familiar, but how your screen displays or handles black is critical while watching movies and looking at photographs.
