I am trying to determine the width and height of the LCD on the camera. I will use the Canon EOS-1DX Mark II as an example.
The display is written as 1,620,000 pixels. This is not intuitive to me as I would like the width and height. I have tried computing in the following way, using the advice of Why does viewfinder spec state 3 times more dots than there are pixels?
I assumed that there are 1,620,000/3=540,000 real pixels and the width:height is in 3:2 ratio (same as the sensor?). By simple arithmetic I arrived at a resolution of 900x600.
Additional Example: The 7D Mark II resolution is listed as 1,036,800 pixels. Using the same basic calculation I arrive at 720x480.
For both examples I arrive and nice round numbers.
Are my assumptions correct?
Why do manufacturers use this notation for lcd resolution?
