通过 VGA 使用 HDTV 时出现过度扫描问题

现在我们能做的就是将电视设置为 1280x768，而不是其原始分辨率 1360x768。将其设置为原始分辨率会导致屏幕左侧的大部分被切断。我们已经尝试了电视上的所有方法，所以现在我们转向 Ubuntu 的内部，希望能够解决这个问题。计算机使用的是 NVIDIA GeForce GT240。这是其当前的 xorg.conf：

电视机的原始分辨率并非 768 线。标准分辨率为 540，高清分辨率为 720 或 1080。它可能从 VGA 连接器接收 1280 x 768 并对其进行缩放。当您为其提供更宽的分辨率时，其缩放范围会比电视更宽。请坚持使用有效的分辨率。
