2025年螢幕選購終極指南：OLED、4K與曲面螢幕，如何挑選不再迷惘？
2025年最完整的電腦螢幕選購指南。從OLED、Mini-LED面板技術，到4K解析度與像素密度(ppi)的關係，再到超寬、曲面螢幕的優劣，PRISM為您深入分析，助您挑選出最適合的螢幕。
您的電腦螢幕用了多久？若仍停留在十年前的1080p時代，那麼升級的時機已然到來。然而，今日的螢幕市場選項琳瑯滿目，令人眼花撩亂。OLED面板的崛起、Mini-LED技術的較勁，加上超寬、曲面等新形態，選擇一台合適的螢幕，已成為一門複雜的學問。本篇指南將為您剖析2025年的關鍵趨勢，助您撥開迷霧，找到最適合的那一台。
決戰畫質之巔：三大面板技術詳解
螢幕的靈魂在於其面板技術，這直接決定了色彩、對比度與反應速度。當前市場主要由以下三種技術主導：
尺寸與解析度的黃金比例
螢幕的清晰度不只看解析度，更重要的是「像素密度（ppi）」。一般來說，超過100 ppi就能帶來細膩的視覺體驗。作為參考，14吋的MacBook Pro像素密度高達254 ppi。以下是常見尺寸與解析度的ppi對照：
| 解析度 | 25吋 | 27吋 | 32吋 |
|---|---|---|---|
| 1920 x 1080 (FHD) | 88 ppi | 82 ppi | 70 ppi |
| 2560 x 1440 (QHD) | 117 ppi | 109 ppi | 92 ppi |
| 3840 x 2160 (4K) | N/A | 163 ppi | 138 ppi |
| 5120 x 2880 (5K) | N/A | 218 ppi | 184 ppi |
從表中可見，27吋螢幕若要達到理想的清晰度，至少應選擇QHD（109 ppi），而4K（163 ppi）則是更佳的選擇。好消息是，近年來27吋4K螢幕的價格已相當親民，甚至在300美元以下就能入手。
重塑工作空間：寬螢幕與曲面潮流
除了傳統的16:9比例，更寬的螢幕正成為新寵。21:9的「超寬螢幕」是雙螢幕的絕佳替代品，不僅適合多工處理，也能在遊戲中提供更廣闊的視野。更極致的32:9「超級超寬螢幕」則為特定用戶帶來無與倫比的沉浸感。這類寬螢幕通常帶有曲面設計，以確保視野中心到邊緣的距離一致，其曲率（如1800R的溫和曲度，或800R的極致包覆感）也是選購時的考量重點。
