The @ref GLFWmonitor object represents a currently connected monitor.
The primary monitor is returned by @ref glfwGetPrimaryMonitor. It is usually
the user's preferred monitor and the one with global UI elements like task bar
or menu bar.
@code
GLFWmonitor* primary = glfwGetPrimaryMonitor();
@endcode
You can retrieve all currently connected monitors with @ref glfwGetMonitors.
@code
int count;
GLFWmonitor** monitors = glfwGetMonitors(&count);

@section monitor_gamma Gamma ramps @section monitor_size Monitor physical size
The physical size in millimetres of a monitor, or an approximation of it, can be
retrieved with @ref glfwGetMonitorPhysicalSize. This can, for example, be used
together with the current video mode to calculate DPI.
@code
int widthMM, heightMM;
glfwGetMonitorPhysicalSize(monitor, &widthMM, &heightMM);
@endcode
@section monitor_name Monitor name
The name of a monitor is returned by @ref glfwGetMonitorName.
@code
const char* name = glfwGetMonitorName(monitor);
@endcode
The monitor name is a regular C string using the UTF-8 encoding. Note that
monitor names are not guaranteed to be unique.
@section monitor_gamma Monitor gamma ramp
The gamma ramp of a monitor can be set with @ref glfwSetGammaRamp, which accepts
a monitor handle and a pointer to a @ref GLFWgammaramp structure.
@code
glfwSetGammaRamp(monitor, &ramp);
@endcode
The current gamma ramp for a monitor is returned by @ref glfwGetGammaRamp.
@code
const GLFWgammaramp* ramp = glfwGetGammaRamp(monitor);
@endcode
If you wish to set a regular gamma ramp, you can have GLFW calculate it for you
from the desired exponent with @ref glfwSetGamma, which in turn calls @ref
glfwSetGammaRamp with the resulting ramp.
@code
glfwSetGamma(monitor, 1.0);
