Control panel is too small to use

For some reason, my virtual control panel is almost microscopically tiny. If I try "maximize", it takes up the full screen but the buttons stay extremely tiny. Changing it to 'programmer' or 'playback' doesn't make a difference.

My laptop screen is 17.5" with 3840x2160 resolution, with my apps size set to 250% - if I change the resolution I lose nearly half of my screen but still doesn't change the control panel size. My secondary monitor is 24" with 1680x1050 resolution.

I haven't seen it do this on other computers and as far as I know I can't resize it so what can I do?

Thank you!
