    need code for an exact pixel manipulation in second monitor

    I am new to OpenGL in windows using VS2017. I am using 2 old graphic GeoForce cards from Envidia model 600 and 700 . Have CUda and OpenGL

    I have a computer with 2 monitors attached. I will like to do a C++ code with OpenGL that will allow me to control each pixel of the second monitor drawing a complex figure produced from a parametric equation for x,y and intensity of colors. Is this possible using OpenGL and where should I start?

    I think in the end you will have to use "gl_FragCoord" ("fragment" ~ pixel), but everything starts by creating an openGL-context...
