兴高采烈，将近晚上11点拿到邮政快递电脑，开箱插上。屏幕亮了一下，无任何显示，背光亮着的，请问各位大神，这是什么原因。接上笔记本戴尔官网下显示器管理程序，可以识别出S2721DGF显示器，但是显示器上只有很少亮光。如图[img]https://img.nga.178.com/attachments/mon_202008/26/c4Q5-bgiaK1wT3cSlc-sg.jpg.medium.jpg[/img][img]https://img.nga.178.com/attachments/mon_202008/26/c4Q5-fzyiK1yT3cSsg-lc.jpg.medium.jpg[/img][img]https://img.nga.178.com/attachments/mon_202008/26/c4Q5-9zgmK1aT3cSsg-lc.jpg.medium.jpg[/img][img]https://img.nga.178.com/attachments/mon_202008/26/c4Q5-bq9gK1bT3cSsg-lc.jpg.medium.jpg[/img]，什么办法都试过，求助！ [img]https://img.nga.178.com/attachments/mon_202008/26/c4Q5-8rpuK1zT3cSsg-lc.jpg.medium.jpg[/img][img]https://img.nga.178.com/attachments/mon_202008/26/c4Q5-9q9eK1wT3cSlc-sg.jpg.medium.jpg[/img]更新连接笔记本电脑，主要按后面菜单键也无任何显示
