The video mode controls the whole image, including the black borders that you get with integer scaling, so those extra pixels need to be factored in. I think you’re right if you’re looking to have the MiSTer output 2048x960, the problem is that unless you’re using a 2048x960 display (or a display that can have its internal scaling turned off and only use part of the screen) this will result in the display distorting the image by scaling it. So it seems the pixel clock is indeed not the cause in this scenario (or I'm calculating the required frequency wrongly). I calculated the minimum required pixel clock for 2048x960 to be 138.2547 mhz. The pixel_clock of video_mode=8 runs at 148.5.
