Retrieving video modes</h1>
|
||
|
<p>Although GLFW generally does a good job at selecting a suitable video mode for you when you open a full screen window, it is sometimes useful to know exactly which modes are available on a certain system. For example, you may want to present the user with a list of video modes to select from. To get a list of available video modes, you can use the function <a class="el" href="group__monitor.html#ga820b0ce9a5237d645ea7cbb4bd383458">glfwGetVideoModes</a>.</p>

Monitor gamma ramp</h1>
|

<p>The gamma ramp of a monitor can be set with <a class="el" href="group__monitor.html#ga583f0ffd0d29613d8cd172b996bbf0dd">glfwSetGammaRamp</a>, which accepts a monitor handle and a pointer to a <a class="el" href="structGLFWgammaramp.html">GLFWgammaramp</a> structure.</p>
