无法将显示器设置为使用 2560x1440

无法将显示器设置为使用 2560x1440

我有一台笔记本电脑,正在尝试插入两个显示器,其中一个应该运行在2560x1440

我已经安装了专有nvidia-331-updates驱动程序,并且(我认为)将其配置为默认使用这些驱动程序(prime-select nvidia

我有一个Intel(R) Core(TM) i7-3537U CPU @ 2.00GHz和一个Nvidia 710m正在运行的 Ubuntu 14.10

当我尝试通过以下方式设置分辨率时:

~$ cvt 2560 1440
~$ xrandr --newmode "2560x1440_60.00"  312.25  2560 2752 3024 3488  1440 1443 1448 1493 -hsync +vsync
~$ xrandr --addmode HDMI1 "2560x1440_60.00"
~$ xrandr --output HDMI1 --mode 2560x1440_60.00

我收到错误:xrandr: Configure crtc 2 failed

输出xrandr --verbose

更新:

按照此处的说明进行操作: https://plus.google.com/+LinusTorvalds/posts/HQsCY7ErAL4 我能够让它输出而没有错误,但现在我的显示器出现“超出范围”错误

答案1

尝试使用 nvidia-settings -> X Server Display Configuration -> Detect Displays。我已成功使用它在两个显示器上显示桌面(一个@2550x1440,另一个@1920x1080)。

答案2

很抱歉,但你运气不好。显示2560x1440像素需要使用更高的图形芯片频率,即使这在芯片的规格范围内,笔记本电脑制造商也会禁用高于该频率的任何功能1920x1080以防止过热。

我还没有看到笔记本电脑的规格说明Support of external monitor @2560x1440 pixels

您可以将闪亮的显示器与具有带 HDMI 输出的独立卡的台式工作站一起使用 - 前提是该分辨率在卡的规格范围内。
