ok, so lets forget about chord length, nor relevant to my case than.
I'm still having some troubles. In warframe and in COGO to move left edge of the screen to the place where right was before movement I need to move mouse around 60mm.
On desktop to move cursor from one edge of the screen to other I need more like 55mm. If Monitor Distance 100% is from the center of the monitor to the edge than it should be 11.8????
I was repeating this test many times and still I'm getting the same results. Reading all above I would expect that movement from one edge to to other to be 100% accurate knowing that there might be some slight error in the middle of the screen, not perfectly on edges. Im on triple monitor set, does it might affect things? Main monitor has different resolution than others.
Also in this case what ratio means?
Sorry for all those questions and thanks for your patience
