Quick Answer
Enable adaptive sync on the monitor and in the graphics driver, then keep the game's frame rate below the 240Hz ceiling. This lets the display follow uneven GPU delivery, reducing visible tearing without the repeated-frame stutter that can occur when fixed refresh timing and game output fall out of step. Configure the whole chain, then test it in the games you play rather than trusting one control panel checkbox.
See the problem before changing settings
Tearing happens when different parts of the screen show frames from different moments at once. It is often most obvious during a fast camera pan, where a horizontal split or misaligned edge crosses the image. Stutter is different: motion can appear uneven because frame delivery and display updates do not line up consistently.
A game does not always produce frames at a perfectly fixed speed. A quiet scene may run faster than a busy fight, while background software, driver activity, or a new game area can create a short drop. A fixed-refresh display can show repeated or partially updated frames when this delivery varies.
Adaptive sync is designed to let the monitor vary its update timing within a supported range so it can better follow the graphics output. It is not a replacement for enough GPU performance, but it can make imperfect delivery look more coherent.
Compare gaming monitors and graphics cards as a matched gaming system.
Enable the feature in the monitor menu
Open the monitor's on-screen display and look for adaptive sync, variable refresh rate, FreeSync, or a similarly named option. Enable it, then leave the menu before moving to the computer. The exact label varies, but the display needs to make the capability available before the graphics driver can use it.
The Legion 27Q-10 specification identifies NVIDIA G-SYNC Compatible support and AMD FreeSync Premium, and separately lists VESA Adaptive Sync. Those capabilities provide routes for variable refresh on compatible NVIDIA or AMD systems, but the connected graphics hardware still needs to be configured.
After enabling the monitor feature, confirm the connection is using the intended port and cable. The product specification includes DisplayPort 1.4 HBR3 and two HDMI 2.1 TMDS ports. Use a suitable direct connection from the graphics card and avoid an untested adapter path while configuring high-refresh gaming features.
Turn it on in the graphics driver
Open the graphics driver's display settings. On a compatible system, look for the option that enables variable refresh or the relevant adaptive-sync mode for the connected display. Apply the change, then check that the driver identifies the Legion monitor correctly.
Do not assume that enabling a game-specific option alone has completed the setup. The monitor menu and driver setting are both important pieces. Some games also have a display or sync option in their own video settings, so verify those after the system-level configuration is in place.
If the option is missing, check the cable, output port, graphics-driver version, and whether the monitor feature is enabled. Test with a direct connection before changing several other variables. A clear connection path makes fault-finding much easier.
Keep frame delivery below the ceiling
The Legion's stated maximum refresh rate is 240Hz. A practical approach is to set an in-game frame limit a little below that ceiling rather than letting the frame rate constantly collide with it. This can give adaptive sync room to work while reducing sudden behaviour at the top of the range.
The correct limit depends on the game and the stability of the hardware. Start with a cap below 240 frames per second, use a repeatable game scene, and watch the frame-time graph or simple in-game counter if one is available. A steady lower number can feel better than a high average that swings constantly.
Do not turn every graphics setting down without testing. Begin at 2560x1440 and the refresh rate you want, then adjust the features that affect the actual title most. The aim is a stable experience, not a screenshot of the highest benchmark result.
Test tearing and stutter separately
Use a familiar quick-pan area or a training mode. Sweep the camera horizontally and watch for the visible split associated with tearing. Then move through a demanding scene and watch whether motion stays even when the frame rate changes. Repeat after changing only one setting.
If tearing is gone but the game still feels slow, look beyond the monitor. High latency can come from network conditions, CPU load, background downloads, storage activity, or game settings. Adaptive sync changes how the display presents frames; it cannot make late data or slow input arrive faster.
If a particular game behaves poorly, try its fullscreen display mode and its own sync setting according to the game's documentation. Keep notes of what you changed so you can return to the stable baseline.
Frequently Asked Questions
What does adaptive sync do?
It lets a compatible monitor adjust its update timing to better match the variable rate at which a graphics system delivers frames. This can reduce visible tearing and uneven motion.
Do I need to enable it on both the monitor and PC?
Yes. Enable the monitor's adaptive-sync option, then activate the appropriate setting in the graphics driver. Check the game's display options afterward if it has its own control.
Why cap frame rate below 240Hz?
Keeping delivery below the monitor's ceiling can give adaptive sync room to operate and avoid constant behaviour at the maximum refresh boundary.
Does adaptive sync fix poor game performance?
No. It can improve how variable frames are displayed, but it cannot fix a weak GPU, overloaded computer, network lag, or a game that is producing frames too slowly.
Configure adaptive sync across the monitor, driver, and game, then play with a frame-rate target your hardware can deliver steadily.
