I understand that the resolution of a display is the number of pixels it can accommodate vertically and horizontally. So if my resolution is 1920 x 1200 it means there are 1920 horizontal pixels and 1200 pixels vertically.
So here are my questions
- Is the pixel size fixed across all display devices? I feel it is not, but please clarify. If the size is different, how are images taken with one device is displayed in some other display device? What is the mapping?
- My PC monitor and Laptop monitor both are 17" in size but the resolutions supported are different. Why is that?
- What happens in the background when I reduce the resolution of my monitor? Why the displayed text/image grows bigger when I decrease the resolution and why does it grow smaller when the resolution is increased?
- What happens when a high resolution image is displayed on a low resolution screen and vice versa
- Many times I notice that large images are displayed as a smaller image such that they fit the display? (Like 'view actual size', 'fit to screen', 'stretch to fit screen' etc) How is the mapping done?
- Does the operating system has anything to do with the resolution? Is there anything like, this operating systems supports only this much resolution?
Throw some light on my questions. I very much appreciate any help.
Thanks in advance.
