How do I get the actual Monitor name? as seen in the resolution dialog
提问by JamesStuddart
I am trying to grab the friendly name for the monitors on my system. I am using C#.
我正在尝试获取系统上监视器的友好名称。我正在使用 C#。
I have tried Screen, which just gives me //./DisplayXX. I have also tried both Win32_DesktopMonitorand EnumDisplayDevices, they all give me variations of //./DisplayXXOR Generic Monitor, whereas I know my displays names are SyncMasterand SM2333T.
我试过了Screen，这只是给了我//./DisplayXX。我也试过Win32_DesktopMonitorand EnumDisplayDevices，它们都给了我//./DisplayXXOR 的变体Generic Monitor，而我知道我的显示名称是SyncMasterand SM2333T。
Now Windows knows what these monitors are, displays them in the Devices and Printerswindows with the correct names, and also in the dialog for setting location and resolution.
现在 Windows 知道这些显示器是什么，在设备和打印机窗口中以正确的名称显示它们，还在用于设置位置和分辨率的对话框中显示。
Where can I grab these names from? I have looked in the registry and cant seem to find them, so any help will be great.
我可以从哪里获取这些名称？我查看了注册表，似乎找不到它们，因此任何帮助都会很棒。
SOLUTION:The issue I had was when calling EnumDisplayDevicesthe second time I was setting iDevNumto id again, which meant I was trying to grab data from the wrong place, I then replaced this with 0, and it works perfectly, see below for the code.
解决方案：我遇到的问题是EnumDisplayDevices第二次调用时我iDevNum再次设置为 id，这意味着我试图从错误的位置获取数据，然后我将其替换为 0，并且它运行良好，请参阅下面的代码。
var device = new DISPLAY_DEVICE();
device.cb = Marshal.SizeOf(device);
try
{
for (uint id = 0; EnumDisplayDevices(null, id, ref device, 0); id++)
{
Console.WriteLine(String.Format("{0}, {1}, {2}, {3}, {4}, {5}", id, device.DeviceName, device.DeviceString, device.StateFlags, device.DeviceID, device.DeviceKey));
Console.WriteLine();
device.cb = Marshal.SizeOf(device);
EnumDisplayDevices(device.DeviceName, 0, ref device, 0);
Console.WriteLine(String.Format("{0}, {1}, {2}, {3}, {4}, {5}", id, device.DeviceName, device.DeviceString, device.StateFlags, device.DeviceID, device.DeviceKey));
device.cb = Marshal.SizeOf(device);
device.cb = Marshal.SizeOf(device);
return;
}
}
}
catch (Exception ex)
{
Console.WriteLine(String.Format("{0}", ex.ToString()));
}

After you get a DisplayDevice.DeviceNamelike //./DisplayXfrom EnumDisplayDevices, you are supposed to call 'EnumDisplayDevices' a second time, this time providing the 'DisplayDevice.DeviceName' that you got from the previous call as lpDevice, and '0' as iDevNum. Then you'll have the monitor name in DisplayDevice.DeviceString.
当你得到一个DisplayDevice.DeviceName像//./DisplayX从EnumDisplayDevices，你应该调用“EnumDisplayDevices”第二次，这次提供“DisplayDevice.DeviceName”你从以前的调用作为了lpDevice，和“0”的iDevNum。然后您将在DisplayDevice.DeviceString.

Examine carefully! this is what you looking for,
you can now write Screen.PrimaryScreen.DeviceFriendlyName()and get the real name of the monitor device.
(and yes, it is the same name seen in resolution dialog)
仔细检查！这就是您要找的，您现在可以编写Screen.PrimaryScreen.DeviceFriendlyName()并获取监控设备的真实名称。
（是的，它与分辨率对话框中看到的名称相同）
While I did add some personal touch to wrap this code I did not create the Hard-Core part of it, And so I would like to thank 2 developers, The MS developer who gave the essentials in C++ and the anonymous developer who translated those essentials to C# code.
虽然我确实添加了一些个人风格来包装这段代码，但我没有创建它的硬核部分，所以我要感谢 2 位开发人员，在 C++ 中提供基本要素的 MS 开发人员和翻译这些基本要素的匿名开发人员到 C# 代码。

This information is almost certainly obtained through the SetupAPIfamily of functions. I don't recall the specifics off the top of my head, but you will need to get all monitor devices (GUID_DEVINTERFACE_MONITOR) and obtain their friendly names (SPDRP_FRIENDLYNAME).
该信息几乎可以肯定是通过SetupAPI系列函数获得的。我不记得具体细节，但您需要获取所有监控设备 (GUID_DEVINTERFACE_MONITOR) 并获取它们的友好名称 (SPDRP_FRIENDLYNAME)。

Well, this question is old, however, as for the sake of google redirects, I suggest my 'WindowsDisplayAPI' library.
好吧，这个问题很旧，但是，为了谷歌重定向，我建议使用我的“WindowsDisplayAPI”库。

Using the library, there are multiple ways to get the display name. The simplest way is:
使用库，有多种方法可以获取显示名称。最简单的方法是：

{
Console.WriteLine(display.DeviceName);

But this is using the old API, if you are sure that your program targets at least Windows Vista, I suggest the following code:

I have been seraching for an answer to this same question. In this linkit is mentioned that generic pnp monitor is shown, because there is no driver installed for the monitor and the device is running with the Generic PnP Monitor Driver.
我一直在寻找同样问题的答案。在此链接中提到显示了通用 pnp 监视器，因为没有为监视器安装驱动程序，并且设备正在使用通用 PnP 监视器驱动程序运行。
For windows 7 and higher there seems to be a different function than EnumDisplayDevices to get the desired display names as shown in the control panel. This can be done with the DisplayConfigGetDeviceInfo function as explained here. I hope someone soon can translate this to Delphi, which I am looking for.
对于 Windows 7 及更高版本，似乎有一个与 EnumDisplayDevices 不同的功能来获取控制面板中显示的所需显示名称。这可以通过DisplayConfigGetDeviceInfo函数来完成作为解释在这里。我希望很快有人可以将其翻译成我正在寻找的 Delphi。
