Will a bigger monitor with the same resolution have an impact on performance?

Will a bigger monitor with the same resolution have an impact on performance? I'm aware that when you increase the resolution of a monitor you tend to see a drop in frames per seconds when running 3d applications (like games, for example), but do you also see a drop in performance if you get a bigger monitor but stay at the same resolution?

"The physical size of the monitor is of no consequence to your computer. The signal that comes out of your computer does not change depending on how physically big the display is, only on the resolution (640x480 or 1024x768) and refresh rate (60Hz, 50Hz, 72hz) of your display. You can use a 17 inch LCD display @1024x768 or a projector putting an image out onto a 10 foot wide movie screen, it's still the same signal.

The only thing that matters is how much data it has construct for every frame. Given a constant frame rate (say, 30 fps in a game) a 640x480 display requires a lot less data per frame than a 1024x768 display.

Now, if the computer doesn't have enough CPU to calculate everything in the time given (1/30th of a second), then it's not going to be updating the frames on time (30 times per second), and you might notice it. If it happens seldom enough, or it's constant enough, you might not."

3D (or any other) performance will be completely unaffected by a change in monitor size if the resolution is unchanged.
