xrandr 失败。错误还是 PEBKEC？

我有一台老旧的电视，我想把它用作显示器，但它扫描不足，电视菜单中没有更改选项。我失去了顶部的整个菜单栏和大部分启动器

我在 Google 上搜索了很多，找到了两种使用 xrandr 解决问题的可能方法

1 按照本页设置欠扫描 https://ubuntuforums.org/showthread.php?t=2141776&page=2&p=12643066#post12643066

2 量程输出 xrandr 默认缩放监视器输出

我可以缩小窗口或者缩放整个桌面吗？

问题是当我尝试这两个选项时，我得到了相同的错误信息

$ xrandr --output HDMI-1 --set underscan on
X Error of failed request:  BadName (named color or font does not exist)
  Major opcode of failed request:  140 (RANDR)
  Minor opcode of failed request:  11 (RRQueryOutputProperty)
  Serial number of failed request:  34
  Current serial number in output stream:  34

$ xrandr --output HDMI-1 --scale 0.9x0.9
X Error of failed request:  BadValue (integer parameter out of range for operation)
  Major opcode of failed request:  140 (RANDR)
  Minor opcode of failed request:  26 (RRSetCrtcTransform)
  Value in failed request:  0x40
  Serial number of failed request:  33
  Current serial number in output stream:  34

我的 xrandr 输出是

当前运行 1280x720，因为我得到的切断较少，但更喜欢 1080，这是显示器的原始分辨率。

在此阶段，任何建议都非常受欢迎。我不擅长使用 CLI，所以非常详细的说明会很好，这样我就可以了解发生了什么以及复制粘贴命令。
