144Hz vs 60Hz 差在哪？動態殘影與 FPS 的影響
一句話說明：更新率是螢幕每秒更新畫面的次數：60Hz 每幀約 16.7ms、144Hz 約 6.9ms，數字越高動作越流暢、越容易追蹤移動目標。休閒與影音 60Hz 就夠用，競技射擊遊戲建議 144Hz 以上，同時也要留意反應時間造成的殘影。
在選購電競螢幕時，「刷新率 (Refresh Rate)」往往是玩家最在意的規格。從早期的 60Hz 到現在主流的 144Hz，甚至高階的 240Hz、360Hz，數字越來越大，但這對遊戲體驗真的有幫助嗎？
144Hz vs 60Hz: Motion Blur & FPS Impact
In one sentence: Refresh rate is how many times per second the screen updates: about 16.7 ms per frame at 60 Hz and 6.9 ms at 144 Hz. Higher is smoother and makes moving targets easier to follow. 60 Hz is fine for casual use and video; for competitive shooters, go 144 Hz or higher, and mind the response time too, since slow pixels cause ghosting.
When choosing a gaming monitor, "Refresh Rate" is often the spec gamers care about most. From the standard 60Hz to the mainstream 144Hz, and even high-end 360Hz, the numbers keep going up. But does it really improve your gaming experience?
什麼是螢幕刷新率 (Hz)？
刷新率是指螢幕每秒鐘更新畫面的次數。60Hz 代表螢幕每秒更新 60 張畫面，而 144Hz 則是每秒更新 144 張。越高的刷新率意味著畫面越流暢，動作之間的過渡越平滑。
為什麼 60Hz 看起來會「卡頓」？
當您習慣了高刷新率後回頭看 60Hz，會明顯感受到「卡頓感」。這並不是電腦變慢了，而是因為人眼對於動態視覺的捕捉能力非常敏銳。在 FPS (第一人稱射擊) 遊戲中，敵人快速移動時，60Hz 的螢幕因為畫面更新間隔較長，會產生明顯的「視覺斷層」，讓您難以精準瞄準。
💡 關鍵知識：動態殘影 (Motion Blur)
除了刷新率，螢幕的「反應時間 (Response Time)」也至關重要。如果螢幕刷新很快 (例如 144Hz)，但液晶轉動顏色變化的速度太慢 (高於 5ms)，就會出現「鬼影」。您可以使用 GearLab 的 UFO 動態殘影測試 來檢查您的螢幕是否合格。
一張表比較：60Hz 到 480Hz
| 更新率 | 每幀停留時間 | 要跑滿需要的 FPS | 適合 |
|---|---|---|---|
| 60Hz | 16.7ms | 60 | 文書、影音、休閒遊戲 |
| 120／144Hz | 8.3／6.9ms | 120–144 | 電競入門，從 60Hz 升級最有感的一步 |
| 165／180Hz | 6.1／5.6ms | 165–180 | 和 144Hz 差距不大，價格相近時可選 |
| 240Hz | 4.2ms | 240 | 競技 FPS（CS2、特戰英豪） |
| 360／480Hz | 2.8／2.1ms | 360–480 | 職業與重度競技玩家，需要很強的 CPU 與顯示卡 |
※ 遊戲 FPS 跟不上時，高更新率的效益會打折；可以用 螢幕數據健檢 確認螢幕真的跑在最高更新率。
為什麼更高的更新率會看得更清楚？
這有兩個層面。第一是幀時間：60Hz 每 16.7ms 才更新一次畫面，144Hz 縮短到約 6.9ms，所以你按下開槍到看到結果的平均等待時間也變短。第二是動態模糊：液晶螢幕會讓每一幀畫面停留一段時間，眼睛追著移動物體時，畫面「停住」的那段會在視網膜上被拉成殘影，這叫做「保持型模糊（sample-and-hold blur）」。
Blur Busters 提出過一個簡化的經驗法則：畫面每停留 1ms，在每秒移動 1000 像素的物體上，大約會造成 1 像素的模糊。所以更新率越高、停留時間越短，追蹤移動目標時畫面就越銳利。這是簡化模型，實際效果還會受反應時間與背光閃爍（如 BFI）影響。
報酬遞減：升級多少才划算？
每次提升更新率，能省下的幀時間會越來越少：
| 升級 | 每幀時間減少 | 感受 |
|---|---|---|
| 60Hz → 144Hz | 約 9.7ms | 差異最明顯，大多數人一眼就能看出 |
| 144Hz → 240Hz | 約 2.8ms | 仍然可以感覺到，但差距變小 |
| 240Hz → 360Hz | 約 1.4ms | 主要給重度競技玩家，需要高 FPS 才能發揮 |
也就是說，從 60Hz 升到 144Hz 是最划算的一步；再往上走，花的錢與電腦需求會快速上升，而實際獲益是否值得，得看你的遊戲類型與預算。
買了高更新率螢幕卻停在 60Hz？檢查這幾個地方
- Windows 設定：設定 → 系統 → 顯示 → 進階顯示 → 選擇更新頻率，確認已切到螢幕支援的最高值（選項名稱依 Windows 版本可能略有不同）。
- 線材與接口：DisplayPort 與較新的 HDMI 才能支援高更新率與高解析度組合。舊的 HDMI 線或接口可能只能跑到 60Hz，換線或換接口常常就解決了。
- 顯示卡驅動：確認驅動已安裝，並檢查顯示卡控制面板中的更新率設定。
- 螢幕選單：有些螢幕要在 OSD 選單裡開啟高更新率或 DisplayPort 1.4 模式。
- 遊戲內設定：部分遊戲預設鎖在 60 FPS 或固定更新率，需要手動調整。
設定完成後，可以用 螢幕數據健檢 確認瀏覽器偵測到的更新率。網頁是透過 requestAnimationFrame 的觸發間隔推算，會受到瀏覽器節流與系統負載影響，數值屬於「估算」，與專業儀器相比有誤差。
更新率不是唯一的條件
- FPS 要跟上：遊戲只有 90 FPS，換再高的更新率也只會顯示 90 張新畫面。
- 反應時間與 Overdrive：液晶變色太慢會有殘影，但 Overdrive 調得太強又會出現反向殘影（亮邊或暗邊），需要用測試圖確認設定是否合適。
- 可變更新率（VRR）：FPS 起伏大時，搭配 G-Sync／FreeSync 能避免撕裂，詳見我們的垂直同步與 G-Sync 文章。
- 面板類型：IPS、VA、OLED 的反應速度與殘影特性不同，詳見面板類型文章。
總結：我需要升級嗎？
- 休閒玩家 / 看電影： 60Hz 已足夠。
- 3A 大作 / RPG 玩家： 建議 75Hz - 100Hz，追求畫質優於速度。
- FPS / 競技類玩家 (CS2, Valorant)： 建議 144Hz 以上。畫面更新更頻繁，移動中的敵人更清楚、更容易追蹤；但實際戰績仍取決於個人技巧，以及遊戲 FPS 能不能跟上更新率。
What is Refresh Rate (Hz)?
Refresh rate refers to how many times the screen updates the image per second. 60Hz means the screen updates 60 times a second, while 144Hz updates 144 times. Higher refresh rates mean smoother visuals and smoother transitions between movements.
Why does 60Hz look "Laggy"?
Once you get used to high refresh rates, going back to 60Hz feels noticeably "laggy." This isn't because your computer slowed down, but because the human eye is very sensitive to motion. In FPS (First-Person Shooter) games, when enemies move quickly, a 60Hz screen has longer gaps between frames, creating "visual stuttering" that makes tracking targets difficult.
💡 Key Concept: Motion Blur
Besides refresh rate, "Response Time" is crucial. If a screen refreshes fast (e.g., 144Hz) but the liquid crystal pixels change color too slowly (>5ms), "Ghosting" will occur. You can use GearLab's UFO Motion Blur Test to check your monitor.
At a Glance: 60Hz to 480Hz
| Refresh rate | Time per frame | FPS needed to fill it | Best for |
|---|---|---|---|
| 60Hz | 16.7ms | 60 | Office, video, casual games |
| 120/144Hz | 8.3/6.9ms | 120–144 | Entry-level gaming; the most noticeable step up from 60Hz |
| 165/180Hz | 6.1/5.6ms | 165–180 | Close to 144Hz; fine if the price is similar |
| 240Hz | 4.2ms | 240 | Competitive shooters (CS2, Valorant) |
| 360/480Hz | 2.8/2.1ms | 360–480 | Pros and hardcore competitive players; needs a strong CPU and GPU |
* When your game's FPS can't keep up, a higher refresh rate helps less. Use the Monitor Health Check to confirm your screen really runs at its maximum refresh rate.
Why Does a Higher Refresh Rate Look Clearer?
There are two parts. The first is frame time: 60 Hz refreshes every 16.7 ms, while 144 Hz cuts that to about 6.9 ms, so the average wait between pressing fire and seeing the result is shorter. The second is motion blur: an LCD holds each frame for a moment, and as your eyes track a moving object, that "held" frame smears across the retina. This is called sample-and-hold blur.
Blur Busters popularized a simplified rule of thumb: each 1 ms a frame is held produces roughly 1 pixel of blur on an object moving at 1000 pixels per second. Higher refresh rates shorten the hold time and keep moving targets sharper. It is a simplified model, and real results also depend on response time and backlight strobing such as BFI.
Diminishing Returns: How Far Is Worth Going?
Each step up saves less frame time than the last:
| Upgrade | Frame time saved | What you notice |
|---|---|---|
| 60 Hz → 144 Hz | about 9.7 ms | The biggest jump, obvious to most people at a glance |
| 144 Hz → 240 Hz | about 2.8 ms | Still noticeable, but the gap is smaller |
| 240 Hz → 360 Hz | about 1.4 ms | Mainly for heavy competitive players, and it needs very high FPS |
In other words, 60 to 144 Hz is the best-value step. Beyond that, cost and PC requirements climb fast, and whether the gain is worth it depends on your games and budget.
Bought a High-Refresh Monitor but Stuck at 60 Hz? Check These
- Windows settings: Settings → System → Display → Advanced display → Choose a refresh rate, and pick the highest value your monitor supports (menu names vary slightly by Windows version).
- Cable and port: Only DisplayPort and newer HDMI versions carry high refresh rates at high resolutions. An older HDMI cable or port may cap at 60 Hz, and swapping the cable or port often fixes it.
- GPU driver: Make sure the driver is installed, and check the refresh setting in the GPU control panel.
- Monitor menu: Some monitors need high refresh or DisplayPort 1.4 mode enabled in the OSD.
- In-game settings: Some games default to a 60 FPS cap or a fixed refresh rate and need manual changes.
Afterward, use the display data check to see the refresh rate your browser detects. The web page infers it from requestAnimationFrame timing, which can be affected by browser throttling and system load, so the figure is an estimate and has some error compared with professional instruments.
Refresh Rate Is Not the Only Factor
- FPS must keep up: If a game runs at 90 FPS, a higher refresh rate still shows only 90 new frames per second.
- Response time and overdrive: Slow pixel transitions leave ghosting, but overdrive set too high causes inverse ghosting (bright or dark halos). Use a test pattern to check your setting.
- Variable refresh rate (VRR): When FPS fluctuates, G-Sync or FreeSync prevents tearing. See our V-Sync and G-Sync article.
- Panel type: IPS, VA and OLED differ in response speed and ghosting behavior. See the panel types article.
Summary: Do I Need an Upgrade?
- Casual / Movies: 60Hz is sufficient.
- AAA Titles / RPGs: 75Hz - 100Hz is recommended, prioritizing image quality over speed.
- FPS / Competitive (CS2, Valorant): 144Hz+ is recommended. The screen updates more often, so moving enemies are clearer and easier to track, though your actual results still depend on your skill and on whether your FPS keeps up with the refresh rate.
