It would not make sense to increase output resolution more than the screen is capable of displaying.
In best case it would have to rescale the output back to its native resolution (it must show is using a fixed number of pixels), which would require processing power and give you a worse result than just using the native resolution (most likely 1366x768, not 1399) due to interpolation errors.
In worst case it would just fail and not give you an image at all.
Sometimes it makes sense to send a resolution lower than the native resolution, e.g. for games where the graphics adapter doesn't have the power to render it smoothly at the native resolution, and use interpolation to show it on the full screen, but this should be avoided.
For completeness: to increase the resolution on your laptop you would have to buy a new laptop panel that is compatible. This is most likely not available, unless you are in real luck and your laptop is part of a series where a higher resolution model is available. It would still be a bit of a gamble to find a new panel unless you can find trustworthy verification of the specific panel model working with your specific laptop model.
If this is not what you mean by your question, you need to clarify.
