title: How Resolution changes X & Y cords
body: <p>I am tracking the color of a pixel at X &amp; Y at a resolution of 1920 by 1080, I am simply wondering if there is any mathematically way to remain accurate in tracking the same pixel throughout various resolutions.<br>
  The pixel is not moving and is static, however I am aware that changing resolutions affects scaling and the X &amp; Y system of the monitor.<br>
  So any suggestions would be great!</p>
