High refresh helps a South African esports player see local motion more often, but it cannot repair an unstable route to the server. The display, PC and network must be judged as separate parts of one match setup.
Quick Answer
Yes, if the game runs well above 144 fps and your connection reaches its competitive server consistently. In South Africa, high refresh sharpens local motion and input feedback, but fibre routing, Ethernet and regional server location still shape the match. At R5,099, the Lenovo Legion 27Q-10 offers QHD at 240Hz with adaptive-sync support for a PC that can provide the frames.
🎯 Confirm the game can use 240Hz
A 240Hz screen refreshes every 4.17ms. That can make tracking a moving target and following a fast camera pan look more continuous than a 144Hz display when the computer delivers a similarly high, steady fps. It is not an automatic benefit simply because the monitor menu says 240Hz.
Benchmark the exact competitive title at 2560x1440 in a busy session. Note the lows and frame-time spikes, not only a high score in a menu. QHD has more pixels to render than Full HD, so a graphics setting that is harmless at 1080p can matter at 1440p. Gaming monitors and graphics cards should be chosen as a pair.
🌍 Separate display delay from network delay
The screen affects how often the local computer can present a finished frame. The internet connection affects when information reaches the game client and when your action reaches the server. A high-refresh panel cannot shorten a congested route, compensate for a distant server, or solve wireless interference in the room.
For an honest test, use Ethernet where possible, stop large downloads on the connection, and play the same server region at the time you normally queue. If the match feels inconsistent while local fps remains stable, compare the game's network display or ping indicator with the frame-time graph. They describe different bottlenecks.
⚙️ Make the monitor configuration repeatable
Select 2560x1440 and 240Hz in the operating system, confirm it in the display menu, and enable adaptive sync in the monitor and driver where supported. The Legion can use AMD FreeSync Premium, VESA Adaptive Sync or NVIDIA G-SYNC Compatible. A sensible frame cap can help when a title repeatedly exceeds the refresh ceiling.
Do not maximise overdrive blindly. A setting that creates bright halos around moving edges is not a competitive improvement. Test your usual sensitivity and a familiar map, then keep the cleanest result at the fps range your PC holds.
Frequently Asked Questions
Does 240Hz lower ping?
No. It improves local display timing, while ping depends on the network route and server.
Is Wi-Fi always unsuitable for esports?
Not always, but wired Ethernet is a useful control when diagnosing inconsistent connection behaviour in the same room.
Should I buy 240Hz if my game runs at 160fps?
It can still provide smooth motion, though it will not use the ceiling continuously. Compare the upgrade against the graphics changes required to reach your preferred range.
