Select 2560x1440 at 240Hz in Windows before opening a game. Use DisplayPort 1.4 or a suitable HDMI 2.1 connection, confirm the new mode in the monitor menu, then tune frame limits and adaptive sync for stable delivery. Set the desktop correctly first so the game begins from a known, high-refresh baseline instead of carrying an old display mode into competitive play.
Start with the cable and graphics output. The Lenovo Legion 27Q-10 has two HDMI 2.1 TMDS ports and DisplayPort 1.4 HBR3. Use DisplayPort 1.4 or a suitable HDMI 2.1 connection from a compatible graphics card. Avoid a chain of uncertain adapters when you are trying to establish the highest intended resolution and refresh rate.
Seat the cable firmly at the monitor and graphics-card ends. If the PC has more than one video output, connect the display to the dedicated graphics card rather than an unrelated motherboard output when the system has a discrete GPU. Check that the cable has enough slack to follow any stand adjustment without pulling on either port.
Before changing game options, let the operating system recognise the display. A stable desktop picture is the first sign that the connection is ready for configuration.
Compare gaming monitors, monitor accessories, and graphics cards as one competitive setup.
Open the Windows display settings, choose the Legion display if more than one screen is connected, and confirm the resolution is 2560x1440. Then open the advanced display page and select 240Hz from the refresh-rate list. Accept the new setting only after the image is stable.
The order matters. Setting resolution and refresh rate in the desktop gives the game a clean baseline. If you open the game first, its own settings may default to an old resolution or a lower refresh rate and make it harder to know which component changed the result.
The Legion 27Q-10 is specified as a 27-inch QHD IPS monitor at 240Hz. If 240Hz does not appear in Windows, recheck the port, cable, graphics driver, and any dock, switch, or adapter between the PC and screen. Test a direct connection before assuming that the monitor cannot offer the setting.
Open the monitor's on-screen menu after Windows is set. Look for the information page or current-signal display and confirm that the active resolution and refresh rate match 2560x1440 and 240Hz. This double-check catches a setup where Windows selected an option but the full connection path did not apply it as expected.
Use the monitor menu to identify its picture and gaming features, but change only one variable at a time. A new competitive setup can involve resolution, refresh rate, adaptive sync, response settings, brightness, and game graphics options. Changing them all at once makes it difficult to identify the cause if the image becomes unstable.
The published feature list carries three adaptive-sync labels: AMD FreeSync Premium, VESA Adaptive Sync and NVIDIA G-SYNC Compatible. They concern matching display updates to delivered frames on compatible systems.
A 240Hz screen can show up to 240 updates per second when the graphics system produces them. Actual game performance depends on the title, graphics settings, game scene, and GPU. It is often better to choose settings that deliver stable, repeatable performance than to maximise one average frame-rate number while frame times vary wildly.
Use an in-game frame limiter or graphics-driver limiter when it helps keep delivery within a steady range. Lower demanding visual settings only after testing their real effect on stability. Start with the game at QHD and 240Hz, then adjust the settings that have the largest impact for that title.
Adaptive sync can reduce tearing when frame delivery changes. Enable it through the monitor, graphics driver, and game settings as appropriate for your hardware. Test it in a game you know well, since a setting that is helpful in one title may need a different frame cap or mode in another.
Choose a familiar competitive game or training area. Move quickly, follow targets across the screen, and test the situation where you normally notice judder or tearing. If the picture is stable and responsive, leave the baseline alone. Fine-tune one item only if you can identify a specific problem.
Do not diagnose network lag as a monitor issue. Connection problems, server performance, CPU load, and background downloads can all affect what a game feels like. A 240Hz display improves the presentation of frames it receives; it cannot fix data that arrives late.
The Legion stand supports height, tilt, swivel, and pivot according to the product details. Use height and tilt so the screen is comfortable from your normal playing position before beginning a long session.
Set 2560x1440 and 240Hz in Windows, then confirm the mode in the monitor's information menu before changing in-game settings.
Use DisplayPort 1.4 or a suitable HDMI 2.1 connection from a compatible graphics card. Test a direct cable path if the expected refresh rate is unavailable.
It can coordinate display updates with the frames delivered by a compatible graphics system, helping reduce visible tearing when frame rate changes.
Check the cable, port, graphics driver, and any dock or adapter. A direct connection is the best first troubleshooting test.
Establish the QHD 240Hz baseline first, then tune your game around stable frame delivery rather than guesswork.
