问题

将图形驱动程序从NVIDIA更新到最新版本（直接下载，不使用Windows Update）后，我的第三台显示器（即Acer V226WL）未显示正确的原始分辨率。原始分辨率为1680 x 1050。我有一台GeForce 660，直到现在我的显示器都没有问题。显示器通过DVI连接。

分辨率不正确：

我尝试过的是：

• 在自定义分辨率工具
• Acer的显示器驱动程序
  • 仅适用于Windows 8的一个，但我不得不尝试一下
  • Had to disable Driver Signature Enforcement to install it too
• Was going to add the resolution to the registry, but saw it was already there
• A different DVI cable
• Disconnecting a monitor / messing with combinations of the connections
• Putting the monitor on another Windows 10 machine of mine that has identical NVIDIA display drivers
• Tried using Driver Sweeper
• Took a look at this question which seems severely outdated. I see no option in the NVIDIA Control Panel to add a custom resolution. Only NVIDIA official article about adding custom resolutions is from 2006. . After using Driver Sweeper, I am now able to define custom resolutions when I wasn't able to before. However:

Custom resolution using the NVIDIA Control Panel:

Trying the Custom Resolution Utility:

I setup the resolution to be 1680 x 1050 yet, take notice that the format is almost 4:3 with black vertical bars on the left and right. It's hard to distinguish in the picture. I added in semi-transparent red lines to show approximately where the monitor edge is, not sure if this is helpful but figured I should. Here is the original image, if you want.

Does anyone have any suggestions as to why this is happening, or how I can troubleshoot it? Like I said, it was fine before the driver update.
