microsoft display dock change resolution

Second scenario is when I have booted the laptop without being connected to the dock and then I later connect to the dock then the fonts and icons on the Dell LCD monitor are so huge that they not only take up too much space on the screen but they look ridiculous. If I reboot the laptop without being connected to the dock then it comes up with fonts and icons correctly sized. The only way I have found to fix the problem is to reboot. If I then disconnect from the dock then the display switches to the laptop, as it should, but the font and icons are so tiny that they are unreadable. Situation 1) if I boot the laptop while connected to the dock then everything is fine on both monitors. My question has to do with screen font and icon sizes after a 'hot swap'. When docked I extend the Lenovo screen to My Dell 27 inch LCD monitor Model AOC 2752H which has a resolution of: 1920 X 1080. I have a Kensington USB 3.0 Docking Station model sd3500v and a Lenovo Yoga 2 Pro laptop with 3200 X 1800 screen resolution.
