Can’t Reset Video Calibration to view full screen

I was playing around in the settings and went to video calibration and started moving the sliders. The top left hand slider went off the screen and now I am unable to view the whole screen and because of the border I cannot retrieve the slider to change the video calibration. I have tried finding the settings data to erase it and uninstalling and reinstalling Kodi as a whole to no avail. I am running the latest version of Kodi on a Windows 10 PC on a 4k monitor.
