获取画面的原始分辨率 [英] Get native resolution of screen

问题描述

有没有办法让一个屏幕的原始分辨率在C＃？

Is there a way to get the native resolution of a screen in c#?

这是我想问的原因是，我有一些曲线，这是非常重要的，他们看起来是一样的，不管什么样的分辨率。当屏幕不处于原始分辨率，他们看起来有点不同比以前，我想显示一个警告，即是如此。

The reason that I ask is that I have some curves and it is very important that they look the same no matter what resolution. When the screen isn't in native resolution they look somewhat different than before and I want to show a warning that that is the case.

推荐答案

从我的经验，最好的解决方法是提取自监视的 EDID

From my experience the best solution is to extract that information from the monitors' EDID

我已经做了一些JavaScript，获取该决议出的8个字节开始于54。

i have made a little javascript that gets the resolution out of the 8 bytes starting at 54.

var dtd = 0;
var edid =  new Uint8Array(8);
var i = 0;

edid[i++] = 0x0E;
edid[i++] = 0x1F;
edid[i++] = 0x00;
edid[i++] = 0x80;
edid[i++] = 0x51;
edid[i++] = 0x00;
edid[i++] = 0x1B;
edid[i++] = 0x30;

var horizontalRes = ((edid[dtd+4] >> 4) << 8) | edid[dtd+2] ;
var verticalRes = ((edid[dtd+7] >> 4) << 8) | edid[dtd+5];
console.log(horizontalRes+", "+verticalRes);

和这里是一个C＃版本：

and here is a C# version:

    static Point ExtractResolution(byte [] edid)
    {
        const int dtd = 54;
        var horizontalRes = ((edid[dtd + 4] >> 4) << 8) | edid[dtd + 2];
        var verticalRes = ((edid[dtd + 7] >> 4) << 8) | edid[dtd + 5];
        return new Point(horizontalRes, verticalRes);
    }
