SDL_GetCurrentDisplayMode not returning correct window size
If you're using the SDL library and the SDL_GetCurrentDisplayMode
function is not returning the correct window size, there are a few potential reasons and troubleshooting steps you can try:
Verify the SDL initialization: Make sure you have properly initialized the SDL library before calling
SDL_GetCurrentDisplayMode
. Ensure that you have calledSDL_Init
orSDL_InitSubSystem
to initialize the library and any required subsystems.Check the window creation: Make sure you have created an SDL window before calling
SDL_GetCurrentDisplayMode
. The window's size and properties may affect the display mode returned by the function. Verify that you have created the window with the desired size and flags usingSDL_CreateWindow
.Check the monitor index: Ensure that you are passing the correct monitor index to
SDL_GetCurrentDisplayMode
. The function takes an index parameter to specify which display monitor's mode you want to retrieve. By default, index 0 represents the primary monitor. If you have multiple monitors, make sure you are using the correct index value.Test on different systems: Try running your code on different systems or with different graphics hardware to see if the issue is specific to your current environment. This will help determine if the problem is related to your system configuration or a specific setup.
Update SDL library: Ensure that you are using the latest version of the SDL library. Check for any available updates or patches that may address known issues or bugs related to display mode retrieval.
Check for error codes: Capture and check any error codes returned by the SDL functions. This will provide more information about potential errors or issues that may be occurring during the retrieval of the display mode.
By following these steps, you should be able to diagnose and resolve the issue with SDL_GetCurrentDisplayMode
not returning the correct window size in your SDL application.
