EnumDisplaySettings not working.

EnumDisplaySettingsA works fine when I pass nullptr, but when I pass hmdDesc.DisplayDeviceName it returns no results. Does anyone know why? Using nullptr isn't an option, because my laptop screen c...

Thanks. That fixed it.
Wow, the Rift supports a lot of resolutions, all the way up to 1920x1200.

const char *g_hmd_device_name = nullptr;

#ifdef _WIN32
static char hmd_device_name[MAX_PATH] = "";
#endif


#ifdef _WIN32
			g_hmd_device_name = hmdDesc.DisplayDeviceName;
			const char *p;
			if (g_hmd_device_name && (p = strstr(g_hmd_device_name, "\\Monitor")))
			{
				size_t n = p - g_hmd_device_name;
				if (n >= MAX_PATH)
					n = MAX_PATH - 1;
				g_hmd_device_name = strncpy(hmd_device_name, g_hmd_device_name, n);
				hmd_device_name[n] = '\0';
			}
#endif


wxArrayString GetListOfResolutions()
{
	wxArrayString retlist;
	retlist.Add("Auto");
#ifdef _WIN32
	DWORD iModeNum = 0;
	DEVMODEA dmi;
	ZeroMemory(&dmi, sizeof(dmi));
	dmi.dmSize = sizeof(dmi);
