Quick Answer
Start with the monitor's factory calibration report, then set the colour space required by your work. Use sRGB for most web content, reserve DCI-P3 for a managed wide-gamut workflow, and measure the panel with a colour meter when accuracy matters. The aim is not the most vivid screen possible; it is a consistent display whose colour mode matches the material you are creating or judging.
Read the factory report as a baseline
A factory calibration report records checks made for the individual display before it reached you. Keep it with the monitor documentation and use it as a starting reference, not as proof that the screen will look identical in every room, operating system, or application. Ambient light, selected picture mode, and the computer's colour handling can all change the result you see.
The Lenovo Legion 27Q-10 ships with a factory calibration report, 99% sRGB coverage, and 90% DCI-P3 coverage. Those figures describe colour spaces the monitor can cover; they are not a reason to use the widest setting for every task.
Before making any changes, place the monitor in the lighting you normally use for editing, viewing, or gaming. Turn off temporary blue-light filters and night-mode features during the calibration process. They can be useful later, but they make a neutral baseline harder to establish.

Use sRGB for ordinary web work
sRGB is the common colour space for web pages, many desktop applications, and a large amount of online image content. If you are preparing material that will mostly be viewed in browsers or standard apps, choose an sRGB-oriented mode when the monitor offers one. This reduces the chance that ordinary images look unnaturally saturated simply because a wider-gamut panel is using every colour it can show.
A colour space is only one part of a complete workflow. Set brightness for the room, use a neutral white balance, and view work in applications that handle colour as expected. Do not compensate for a too-bright room by changing saturation or contrast until you have dealt with the ambient light.
For a casual gaming session, you may choose a different picture preference, but keep that separate from a web or creative work profile. Switching deliberately is better than editing an image in a vivid game mode and wondering why it changes elsewhere.
Reserve DCI-P3 for managed workflows
DCI-P3 is a wider colour space than sRGB. It can be useful when the source material, application, and output target are all part of a managed wide-gamut workflow. That might include content intended for a known colour-aware environment, rather than a general browser audience.
Do not select a DCI-P3 mode only because the colours appear more intense at first glance. If an application assumes sRGB while the monitor is presenting a wider gamut without proper management, familiar colours can look over-saturated. The brightest red or green is not necessarily the most accurate one.
The Legion monitor's listed 90% DCI-P3 coverage is a capability you can use when the work calls for it. Keep a simple record of which profile you use for each kind of task so that a return to sRGB work does not become a guessing game.
Measure when accuracy has consequences
A colour meter measures light from the panel and can create a display profile for the connected computer. This is the strongest way to tune a monitor when colour accuracy affects a client deliverable, print comparison, video grade, or repeated team workflow. Follow the meter software instructions and allow the display time to stabilise before measurement.
Use the meter in the same room conditions in which the screen will be used. Recheck after a major lighting change, a long period of ownership, or a reset to monitor settings. A profile made for one display does not automatically make a laptop panel or second monitor match.
Without a meter, test patterns can still help. Look for a smooth greyscale, distinct dark tones, and colours that do not appear heavily tinted. This is a visual improvement method, not a measurement substitute, so avoid making strong claims of accuracy from an unaided test.
Keep the workflow repeatable
Save the selected monitor mode and computer profile, then label them by purpose: web sRGB, managed wide gamut, or casual gaming. This makes it easy to return to a known baseline after another user changes the settings or a driver update resets a profile.
The Legion 27Q-10 is a QHD IPS gaming monitor with HDR10 and Dolby Vision support in its published specifications. Those playback features are separate from choosing a working colour space. Configure the mode for the content you are viewing, then do not mix an entertainment profile into colour-critical work without checking the result.
Frequently Asked Questions
Should I use sRGB or DCI-P3 for web images?
Use sRGB for most web content. Use DCI-P3 only when the source, application, and intended output are part of a managed wide-gamut workflow.
What does a factory calibration report tell me?
It provides a documented starting baseline for the individual monitor. Room light, selected mode, and computer settings can still affect the result you see.
Is a colour meter necessary?
It is the best option when accuracy matters because it measures the panel and can create a profile. Test patterns can improve a display by eye but do not replace measurement.
Does wider gamut always mean better colour?
No. A wider gamut can look more vivid but may over-saturate sRGB material if the workflow is not managed. Match the monitor mode to the colour space of the work.
Give each colour task the right working space, then let consistency matter more than instant visual punch.
