Quick Answer
Begin with an sRGB preset if the monitor menu offers one, then adjust brightness for the light in your room and aim for a neutral 6500K white point. A colourimeter is the strongest way to measure the result, but carefully used test patterns can still improve a screen by eye. The Lenovo L24-4e combines an IPS panel with 99% sRGB coverage, so a calm, consistent setup is more useful than random slider changes.
Prepare a stable viewing environment
Calibration starts before you open a monitor menu. Let the display run for a little while so its appearance settles, then work in the lighting you normally use for photo viewing, design, documents, or web work. A bright window behind the monitor, a lamp shining onto the panel, or a screen positioned in direct sun can make you over-correct settings that were not the real problem.
Clean the panel gently and set your normal viewing position. The L24-4e is specified with an anti-glare coating, but a reflected lamp can still affect what your eyes judge as dark or neutral. Use the tilt stand to reduce reflections before changing colour values.
Avoid making colour decisions while a blue-light filter, night mode, or colour-altering app is active. Those tools can be useful at other times, but they interfere with a reference setup. Turn them off for the adjustment, then decide later whether you need them in a separate evening profile.

Begin with a sensible preset
Open the monitor's on-screen display and look for picture modes or a colour preset. If an sRGB mode is available, use it as a controlled starting point for work intended for the sRGB colour space, which is common for web images and many everyday applications. Do not assume that every vivid-looking mode is more accurate. Strong saturation can be impressive while making familiar colours look unnatural.
Next, look for a colour-temperature control. A 6500K target is commonly used as a neutral daylight-like reference for display work. The menu may use labels such as Normal, Warm, Cool, or User rather than showing an exact number. Choose the option closest to a neutral appearance, then avoid compensating by making the display excessively blue or yellow.
The Lenovo monitor's documented 99% sRGB coverage describes the colour range the panel can reproduce. Calibration is about how that capability is used in your room and workflow. Starting from a known preset gives you a better baseline than changing contrast, colour, and brightness all at once.
Set brightness for the room, not the showroom
Brightness is one of the most visible adjustments. A display that is too bright for a dim room can make white pages feel harsh and lead you to edit images darker than they should be. A display that is too dim in a bright office can hide shadow detail and make you push images too light.
Open a simple white page beside a familiar document or print reference if you have one. Adjust brightness until the page is comfortable to read for several minutes without the screen looking grey or painfully bright. The L24-4e is specified at 250 nits, but the useful setting depends on your ambient light rather than a single slider position.
Keep contrast near its default unless a test pattern shows an obvious issue. Large contrast changes can crush very dark tones or erase detail from highlights. It is usually better to make small brightness changes, pause, and judge the screen with normal content.
Use a colourimeter when the result matters
A colourimeter measures the light from the display and creates a profile for the connected computer. This is the most reliable route for colour-sensitive tasks because it replaces guesswork with measurements. Follow the device software's instructions, keep the room lighting consistent, and apply the profile only to the display it measured.
A profile on one screen does not automatically fix every other screen in a multi-monitor setup. Calibrate each display separately if matching between devices is important. Also remember that another person's laptop, phone, or printer may show the same image differently. Calibration improves your controlled reference; it does not eliminate variation elsewhere.
If you do not have a colourimeter, use neutral greyscale and colour test patterns as a practical visual check. Look for smooth steps from black to white, greys that do not look strongly tinted, and colours that remain distinct without glowing unnaturally. This is not a substitute for measurement, but it can expose clearly poor settings.
Check the result with familiar work
After adjustment, return to the documents, photos, and browser pages you use every day. Text should be easy to read, skin tones in trusted images should not lean strongly orange or blue, and grey areas should look balanced. Give your eyes time to adapt before making another change.
Save a note of the selected preset, brightness level, and temperature choice. That makes it easy to recover the setup after a reset or a shared workspace change. If the room lighting changes significantly between day and night, make a second profile rather than chasing one compromise setting all day.
Frequently Asked Questions
What is a useful starting point for colour calibration?
Use an sRGB preset when it is available, set a neutral white point around 6500K, and adjust brightness for your usual room lighting. Then check with normal content.
Is a colourimeter necessary?
It is the best option when accurate colour matters because it measures the display and can create a profile. Test patterns are still useful for a careful visual improvement.
Should I turn brightness all the way up?
No. Set brightness for comfort and the ambient light in your room. A showroom-bright screen can make normal work tiring and distort visual judgement.
What does 99% sRGB mean for this monitor?
The product information states that the IPS panel covers 99% of the sRGB colour space. That gives a suitable basis for sRGB-oriented work when the display is set up consistently.
Give your monitor a stable colour baseline, then make visual decisions with more confidence every day.
