As of Intel driver version v26.20.100.7985, 5120x1440 is now also supposed to be supported. The question is, however, whether the monitor also supports this resolution.
You can choose whether you want the picture to be stretched or simply have black bars on the side. Keep in mind, however, that the graphics chip is running at its limit and therefore the cooler of the notebook will probably be rather noisy. I would only recommend this monitor if you can use the pixels.
Windows 10, as an example, would choose a resolution that corresponds to the maximum possible resolution of the notebook and the screen would then convert the data position with the pixels chosen by Windows. Perhaps it would be better to choose a 32 inch 4K screen that matches the graphics performance of the processor.
