Quick Answer
Select 280Hz in Windows, match the GPU output, enable adaptive sync, and confirm the result with a frame-rate test. The Lenovo Legion 27-2c provides DisplayPort 1.4 and two HDMI 2.1 inputs, but the chosen port and cable must support the requested mode. Configure the physical connection first, then set the refresh rate in the operating system and game, and finally test whether the GPU can deliver a stable frame rate near the display target.
Begin with the connection
Use a cable and output on the graphics card that are appropriate for the monitor mode you want to use. Connect the display directly to the GPU rather than assuming every port on a dock, adapter, or older cable will expose the highest refresh option. Check that the connector is fully seated at both ends before turning to software settings.
The Legion 27-2c lists one DisplayPort 1.4 input and two HDMI 2.1 inputs. These are the available product inputs, but the usable mode also depends on the source device and cable. A port label alone is not proof that a particular computer is outputting the refresh rate you expect. If 280Hz is not available in the settings, work through the connection before changing several software options at once.
Avoid relying on an unverified adapter for a competitive setup. An adapter can introduce a mode limitation that is difficult to diagnose from the Windows menu. Start with a direct cable when possible, then add other hardware only after you have confirmed the basic connection.
Compare gaming monitors with the outputs available on your GPU and the way you intend to connect the display.
Set the refresh rate in Windows
After connecting the monitor, open Windows display settings and select the Legion as the active screen. Go to the advanced display options and choose the highest available refresh rate for that monitor. Confirm the selection, then return to the desktop and check that the display remains stable.
If Windows shows a lower maximum, do not assume the panel is defective. Check the cable, GPU output, monitor input selection, and graphics driver. Disconnect any unnecessary display adapter or splitter during troubleshooting. A clean direct connection makes it easier to identify what is limiting the available modes.
The Legion 27-2c is a 280Hz display. That number describes the monitor's maximum refresh capability, while the source system must still be configured to send the corresponding mode. Selecting it in Windows is a necessary step; it is not the end of the verification.
Match game settings to the display
Open the game you play most often and check its display mode, resolution, and frame-rate settings. Use the monitor's native listed resolution of 1920x1080 when you want the direct panel mapping. Then choose the intended refresh rate in the game's display menu where that option is available.
Exclusive full-screen and borderless modes can behave differently between games and systems. Do not change every setting blindly. Make one adjustment, apply it, and verify the reported refresh rate. A stable familiar test scene is more useful than a complicated benchmark while you are still checking configuration.
Cap the frame rate sensibly if the game offers a reliable limiter. The right cap depends on the title, your GPU performance, and whether adaptive sync is active. The aim is consistent frame delivery, not merely a high number during a quiet menu. Test a real match, practice range, or repeatable scene with the effects you normally use.
Enable adaptive sync carefully
The Legion 27-2c lists AMD FreeSync Premium and VESA Adaptive Sync support. Adaptive sync can help the refresh timing follow changing frame delivery, reducing the visual mismatch that can occur when the GPU and monitor are not in step. It is one part of a smooth setup, not a substitute for adequate game performance.
Enable the relevant option in the monitor and GPU software according to your hardware. Then test a demanding scene where frame rate changes. Look for stable motion rather than relying only on a checkbox being enabled. If you notice unusual behaviour, return to one setting at a time: refresh rate, game frame cap, adaptive sync, and cable connection.
The monitor's listed 0.5ms MPRT response figure relates to a motion-response measurement. Treat it as a product specification, while judging your own competitive experience through clear movement, stable frame delivery, and the settings you can maintain across games.
For wider component planning, browse gaming setups after confirming that the GPU, connection, and monitor settings work together.
Verify before trusting the number
A frame-rate test or trusted in-game performance overlay can confirm whether the game is rendering near your intended target. Watch the result during actual play, not only a menu. If the frame rate falls far below the refresh rate in the moments that matter, reduce a few graphics settings or choose a cap that the system can hold more consistently.
Also verify with your eyes. Move through a familiar area, track a moving target, and observe whether the display feels stable. Sudden stutter can come from game settings, background work, drivers, or the source hardware. The monitor refresh setting is only one part of the chain.
Use the Legion's height, swivel, pivot, and stand adjustment to place the screen comfortably before a long session. A well-configured high-refresh display is more useful when the viewing position also lets you see the full panel without strain.
Frequently Asked Questions
Why is 280Hz not visible in Windows?
Check the direct cable, GPU output, monitor input selection, and graphics driver. The selected port and cable must support the requested mode.
Should I use the monitor's native resolution for competitive gaming?
The Legion 27-2c lists 1920x1080 as its native panel resolution. Start there when configuring the direct panel mode, then adjust game settings based on performance.
What does adaptive sync do?
It can coordinate monitor refresh timing with changing GPU frame delivery. The Legion 27-2c lists AMD FreeSync Premium and VESA Adaptive Sync support.
How do I know the game is using the setting?
Use a trusted frame-rate test or in-game overlay during an actual scene. Check both the reported figures and the stability of visible motion.
Confirm the direct connection, select 280Hz deliberately, enable the sync option that suits your GPU, and verify the result in the game you actually play.
