A 240Hz monitor is worth buying when the games you care about can actually feed it. For a solo campaign, the improvement is mostly smoother camera movement and lower perceived blur; for competitive play, the smaller frame interval is more likely to change how immediate aiming feels.

Quick Answer

240Hz is worthwhile for competitive games when your PC sustains very high frame rates; it is less decisive for slower solo titles. You still gain smoother camera motion, but image quality, HDR and resolution may matter more in a cinematic campaign. At R5,099, the Lenovo Legion 27Q-10 gives a 27-inch QHD IPS panel a 240Hz ceiling, so the sensible question is whether your actual games can use that ceiling.

🎯 Start with the game, not the refresh-rate number

Competitive games reward repeatable motion and rapid decisions. At 240Hz, a refresh occurs every 4.17ms; at 144Hz it is about 6.94ms. That difference does not turn an inconsistent player into a strong one, but it can make a fast pan, tracking movement or a flick shot look more continuous when the PC is supplying frames at a similar pace.

Single-player games are a different decision. A slow tactical game, turn-based game or story-led adventure can look excellent at lower frame rates because its camera motion and aiming demands are less severe. In that case, QHD detail, colour behaviour, contrast in a dark scene and the quality of the image settings may be worth more than chasing a 240fps result. Compare gaming monitors with the genres you play most, rather than treating a high refresh label as a universal upgrade.

🧪 Measure sustained fps before you spend

Use the same demanding part of a familiar game for a practical test. Set the game to 2560x1440, play for ten minutes in the busy area that normally causes the lowest performance, and watch a frame-rate counter or frame-time graph. Record the low range as well as the peak. A title that briefly hits 240fps in a menu is not a title that will show why 240Hz matters during a match.

If the range is around 90 to 140fps, a 240Hz monitor still works normally, but the result is not identical to a game held near 200fps or above. Lowering a costly effect, reducing ray-traced lighting, or choosing a sensible upscaling mode can be a better first move than replacing hardware. The Legion 27Q-10 supports 2560x1440 at up to 240Hz, and it has NVIDIA G-SYNC Compatible and AMD FreeSync Premium support for suitable systems. Variable refresh helps when delivery moves around rather than remaining fixed.

For a graphics upgrade decision, look through graphics card options after you have measured the games and settings you use. A faster monitor cannot create frames the PC did not render.

🖥️ What 240Hz changes in a campaign

The common mistake is to frame solo games as unable to benefit from high refresh. Smooth scrolling, racing through a detailed environment, a responsive camera and reduced sample blur can all be pleasant at 240Hz. The benefit is simply easier to trade against other priorities. A player who prefers a visually rich 80fps experience may choose higher texture detail or a stronger HDR presentation instead of reducing settings merely to reach a high number.

QHD has a visible role at 27 inches because it provides more detail than Full HD while keeping the screen compact enough for an ordinary desk. The Legion model combines that QHD resolution with an IPS panel, 99% sRGB coverage, 90% DCI-P3 coverage, HDR10 and Dolby Vision support. Those are capabilities to assess with the content you use, not proof that every HDR game will look the same. A dim room, game tone mapping and the panel's behaviour all affect the outcome.

⚙️ Make the high-refresh mode real

After connecting the display, select 2560x1440 and 240Hz in the operating system, then confirm the reported mode in the monitor menu. Use a direct DisplayPort 1.4 HBR3 connection or one of the listed HDMI 2.1 TMDS inputs with a suitable cable. A high-refresh screen left at a lower desktop setting will not show its intended motion behaviour.

Enable adaptive sync in both the display menu and the relevant graphics-driver panel. Then set a frame cap that your PC can maintain in the game you play most. The goal is not an impressive one-time benchmark; it is stable delivery without frequent swings that make motion feel uneven. Test with your normal sensitivity and brightness because a setting that looks fine on a static menu may expose trailing or tearing during play.

Frequently Asked Questions

Is 240Hz useful below 240fps?

Yes. The display can still refresh at 240Hz, and adaptive sync can help it follow changing frame delivery on a compatible system. The full advantage is more obvious as frame rate becomes higher and steadier.

Should a single-player gamer buy 240Hz?

Buy it if smoother motion is valuable to you and the rest of the monitor also suits your games. Do not sacrifice resolution, colour or settings you enjoy merely to hit a headline frame rate.

Does QHD make 240fps harder to reach?

Usually, yes. Rendering 2560x1440 asks more of the graphics card than 1920x1080, so test at the resolution you plan to use before judging the monitor.
