Sony Vaio 外接显示器问题

我在 Sony Vaio 笔记本上启用外接显示器时遇到问题。它被成功检测到，但当我尝试启用第二个外接显示器时，屏幕出现故障和延迟（就像视频驱动程序无法正常工作一样），第二个显示器上什么也不显示。当我只使用外接显示器时，一切似乎都好起来了 - 没有闪烁和故障，但当我尝试扩展时，问题就开始了。我使用专有的 fglrx-update 驱动程序。以下是 xrandr 的输出：

更新

我已设法使用以下命令使其通过 VGA 工作：

xrandr --output VGA1 --auto --right-of LVDS1 --output VGA1 --scale 1.0001x1.0001

但是，它无法通过 HDMI 工作。

答案1

因此，xrandr 的 --scale 选项正在修复闪烁的图像。之后，为了修复“无信号”问题，我需要打开“显示设置”应用程序，将外接显示器拖到内置显示器周围的任意位置，然后点击“应用”，然后一切就开始正常工作了。
