Could you make "extended" mode?

Hello, I've purchased and have been using nano kvm lite.
However, I'm experiencing an issue where fixing the resolution causes the screen to shrink to that resolution.
Please enable an "extended" mode that allows the user to set a desired resolution, similar to TeamViewer.
This would be very helpful for achieving higher FPS on poor internet connections by using a lower resolution.
(This is translated, so it could be a bit strange.)
