Does your setup actually affect your rank?The numbers, honestly

Scroll across for mouse timings and totals.

Keep the mouse at 125 Hz and the sum drops from 12.3 to 7.5 ms when the display changes. Raise polling to 1000 Hz as well and it falls to 4.0 ms. That extra reduction belongs to the mouse. You can't credit the monitor with all of it.

This is an illustrative model of two waits, not a full latency measurement. Real systems add rendering and queues; display scanout and pixel response also matter. The phases can interact. NVIDIA's system latency breakdown explains why the number on a monitor box doesn't describe the whole chain.

For scale, Woods and colleagues' visual reaction study reported a 231 ms mean, or 213 ms after correcting for hardware delay. Using 200 to 250 ms as a rough benchmark makes the 4.9 ms saving about 2%. League adds recognition and decision-making; a reaction test doesn't measure either.

The move from 144 to 240 Hz saves another 1.4 ms in this model. Higher refresh can also make motion easier to follow. Neither effect tells us how many divisions someone will climb. We haven't run a controlled LoL rank experiment, and these calculations shouldn't be read as one.

A counter saying 240 FPS in fountain tells you very little about a five-player engage. If the next frame takes 50 ms instead of 4.2 ms, you get a hitch exactly when you need to track movement. That single illustrative stall is much larger than the 1.4 ms refresh-wait difference above.

Riot makes this same distinction in its League performance monitoring write-up: a good match average can hide slow teamfights. Watch how your game behaves under load. A steadier 144 FPS can feel easier to control than a higher average interrupted by visible hitches.

Lower a graphics setting, close a recording app, then repeat the same situation. Change one thing at a time. Buying a faster monitor won't fix a CPU stall, and a 240 Hz screen doesn't make your PC render 240 frames every second.

Suppose your usual 30 ms ping jumps to 90 ms. That's a 60 ms change in round-trip time, over ten times the modeled 60-to-144 Hz saving. Ping is round-trip network time, so this isn't a direct click-to-photon comparison. A small display improvement can't repair a bad connection.

Jitter means delay varies; packet loss means some data never arrives. Riot tracks latency, packet loss and jitter to understand the player experience. Try Ethernet if Wi-Fi is inconsistent, pause downloads, and check whether trouble follows busy household hours. A faster mouse won't change the route to the server.

Pro players and our Challenger boosters have reached Master and Grandmaster and completed boosts from other countries at around 150 ms ping. That's an observation from EloAscend's team, rather than a controlled comparison with their low-ping results.

That alone is a useful answer to "my setup is why I'm stuck." High ping can make a play harder. It doesn't automatically keep a skilled player out of high elo. A booster still has to read the wave and choose a fight worth taking.

Fix the connection when you can. Give your decisions the same attention. Setup affects performance; it doesn't determine your rank by itself.

A desk sold as 29 or 30 inches high, roughly 74 to 76 cm, still has to fit the person sitting at it. Start with the chair: feet supported, back comfortable, shoulders relaxed. With your elbows beside your torso, check where your hands meet the keyboard and mouse.

The useful measurement is the height of your input surface relative to your seated elbow. OSHA's keyboard guidance puts the elbows about level with the keyboard and the wrists in line with the forearms. Account for the keyboard's thickness when choosing a desk or tray. The tabletop alone isn't the typing surface.

If you have to shrug to reach the mouse, the surface may be too high. Raising the chair can help, provided your feet stay supported and your thighs have room. A lower tray or adjustable desk gives you another way to fit the surface to your body.

Place the monitor straight ahead with its top at eye level or slightly below. OSHA's monitor guidance gives a normal viewing angle of about 15 to 20 degrees downward toward the center. You shouldn't need to lift your chin to read the minimap.

For your mouse hand, look for a wrist that continues the forearm's line. A bend upward or a hard desk edge pressing underneath deserves an adjustment. Keep the mouse close enough that you aren't reaching through every trade. Check the guidance on palm supports before treating a wrist rest as a cure; pressure directly on the wrist can create another problem.

These adjustments address comfort and strain. We don't have evidence that a particular desk height adds LP or a chair improves win rate. The practical goal is to reach game three without spending half the lane shifting around to get comfortable.
