英文:
Java Awt mouse position coordinates calculation
问题
我可以通过以下代码获取光标的位置，但我不理解坐标是如何计算的。
MouseInfo.getPointerInfo().getLocation();
如果鼠标位于右上角，坐标为"java.awt.Point[x=2047,y=0]"，但我的屏幕分辨率是2560 x 1440，所以我预期坐标应为[x=2560,y=0]。
那么这些坐标是如何计算的呢？
英文:
I can get the Position of the cursor by the following code, but I don`t understand how the coordinates are calculated.
MouseInfo.getPointerInfo().getLocation();
If the mouse is in the right top corner the coordinates are "java.awt.Point[x=2047,y=0]", but the resolution of my screen is 2560 x 1440 so I expected the coordinates to be [x=2560,y=0].
So how are these coordinated calculated?

当我尝试这样做：
while(true){
System.out.println(MouseInfo.getPointerInfo().getLocation());
Thread.sleep(1000);
}
它输出：
java.awt.Point[x=1919,y=0]
而我的屏幕分辨率是 1920x1080。所以似乎存在屏幕或系统的某些问题。你确定你的系统“知道”你有这样的屏幕吗？
英文:
When I try something like:
while(true){
System.out.println(MouseInfo.getPointerInfo().getLocation());
Thread.sleep(1000);
}
Its printing out:
java.awt.Point[x=1919,y=0]
And I got 1920 1080
So its seems to be some problem with your screen/system. Are you sure your system "knows" that you have such a screen?

我的Windows选项用于“显示 -> 缩放和布局”设置为125％。
问题就在这里，如果我将其设置为100％，它会按预期工作。
英文:
My windows options for "Display -> Scale and layout" are set to 125%.
Thats the problem, if i set it to 100% it works like expected.
