Unverified80% confidenceCautionTime unknown
预算有限时不建议为高分辨率2K屏叠加高刷，2K+120Hz全开对功耗与GPU压力大且发热明显，中端芯片机型开2K高刷易掉帧，1.5K分辨率+120Hz是更均衡的选择

Unverified高刷高分屏耗电快，2.5K 240Hz屏比1080p 144Hz屏续航明显更短，且需更强GPU才能喂饱帧率，屏幕规格与GPU档次要匹配否则浪费85% similarUnverified分辨率与刷新率难以兼得：5K2K(5120×2160)高PPI屏几乎都锁定在120Hz以内且价格昂贵，追求165Hz+高刷竞技的应选UWQHD(3440×1440)VA/OLED面板，二者不可兼得需明确优先级84% similarUnverified高分辨率(2.8K/4K)屏幕更清晰但显著增加GPU负载和耗电，13-14寸机型2.2K-2.5K是清晰度与续航的甜点，4K在小屏上收益边际递减83% similarUnverified预算有限却想要高刷+高分辨率+大尺寸三者兼得不现实，34英寸WQHD 144Hz是性价比甜点，追求5K2K则须为分辨率牺牲刷新率或大幅加预算81% similarUnverified刷新率越高越流畅但对分辨率和显卡要求越高：4K@144Hz需要DP1.4+DSC或HDMI2.1，且中高端显卡才能推动；纯办公60Hz足够，2K电竞选144-165Hz性价比最高81% similar
