很抱歉沒幫到你
硬體沒問題的話可能是驅動與解碼器問題了
https://m.mobile01.com/topicdetail....4&t=5409794&p=1
參考9樓...

用虛擬器或用Live CD跑看看是不是也一樣

各位肯撥冗指教已經是很感激的啦，雖然你引的連結我已經看過，
不過可能有疏漏的部分，我再仔細看看。

不是專業電腦玩家,也許提供的訊息很粗淺,勿見笑.是否將播放軟體的解碼模式改為軟件解碼會有所改善,一般預設值都是硬體解碼.各播放器的設定UI介面都不同,需要花時間找一下.

這些是問題剛發生時第一個想到的癥結，同樣一套PotPlayerPortable，
同樣在win10家用版，同樣的影片，在桌機和筆電上執行就不同結果，
還試過32bit版、安裝版、加裝可以想到的解碼器(即使面對的是各類格式都定格的狀況)
目前還是無解的。

下載dxva checker看看
看youtube 1080P也會嗎
