Do larger monitors slow down winforms applications?

Question

Will WinForms apps run slower on larger monitors(i.e. larger resolution) as opposed to smaller all else being equal? My gut says yes, as there's more real estate to paint, but I cannot find any information anywhere regarding the effects.

I ask because we have a WinForms application that generally runs on two 22 inch monitors, but we have a couple users who run it on two 30 inch monitors, and they always seem to have more lag in their GUI than anyone using the 22 inch monitors.

Answer 1

The issue isn't really the number of inches, its the number of pixels.

Drawing to a 800x600 screen is less work than drawing to a 1920x1080 screen (roughly 4x less work).
Still, most of that work is likely done by a graphics card, and won't affect CPU load all that much.
