The latter has 4 times the number of pixels, so it requires 4x the amount of memory and a simple operation like glClear might take 4 times longer to complete. It only cares about the resolution, for example 1920x1080 vs 3840x2160. It could also mean the space between the pixels is different.Īd 2) No, the physical size of a monitor makes no difference for the GPU. If you try to test displaying the same image on different-sized monitors, and they are using different values for this setting, the image probably won't be the same number of pixels on the monitors, because it's being scaled up according to this setting.Īd 1) Yes, if both monitors have the same resolution but different screen sizes, this means the pixels of the larger monitor are bigger. This is more likely to be set high on a small, high-resolution screen than on a large, high-resolution screen. If this setting isn't set to 100%, most things on the screen are scaled up even if the program isn't scaling them. In Windows the option is called "Change the size of text, apps and other items". The only caveat is that most OSes have some kind of pixel scaling method now, so that icons, buttons, and text aren't unusably small on modern high-resolution displays. If your screen is 1920x1080 pixels, and you display a 960x540 image without any scaling, the image will stake up a quarter of the screen, and it won't take any more GPU time to display on a larger monitor. The answer to both your questions is the same: the physical size of the monitor makes no difference at all.
