Measuring screen resolution?

My monitor resolution is set as 1280x800. Is it possible that different size monitor can have same resolution ? If yes, then will it make the image less clear for the bigger screen ? How do I know, what resolution shall I keep in order to see image properly ?

When we change the resolution of the screen, how does it change physically on the screen ?

I mean, screen has 1280x800 pixels i.e. thats the fixed hardware part. Now , when I change resolution from the properties, how will it change the physical property of screen ? Is it the video card which is responsible for resolution or is the screen itself ?Measuring screen resolution?
Yes a bigger monitor may be capable of running at the same resolution and yes it wont be as sharp. These numbers are the number of dots vertically and horizontally on your screen. I.E., if you are running at 1280 by 800, the rows going across have 1280 dots or pixels, the row going down has 800 dots or pixels. Multiply the 1280 by 800 and you will get the total number of pixels on your screen. As you can see, the higher the resolution, the more pixels and therefore the sharper the picture.Measuring screen resolution?
if when you change resolutions, the monitor stays completely filled it means your monitor is stretching the video to use all of the pixels.



if it doesn't than the image you are seeing is exactly the resolution you picked.



im 95% of the cases, it is the monitor that affects the resolution and only if you plug a super low end computer into a large monitor will that switchMeasuring screen resolution?
dont really get what you mean but screen resolution is dependent on your monitor capacity... the video card just manages the output depending on your what resolution you set.



but to get best display you must set your monitor to max resolution always... because if you have a 1280x800 max resolution and you set it to 1024x768

you will get a stretched display ...Measuring screen resolution?
Yes, a monitor of a different size can have the same resolution, but by definition it will have a different dot or pixel pitch (size or amount of space between each pixel). For example, there's 720p HDTVs that are 19 inches, and there's 720p HDTVs that are 50 inches. Same resolution, very different size; on the larger sets you can see the fine detail more clearly, although that means you're also more likely to see individual pixels (not as realistic looking). LCD monitors have native resolutions at which you should display for best results.

By changing the resolution, the video card outputs a different resolution, different video processing and what not. If it's a CRT monitor, it will accept this signal and display it as is, and yes it will actually be doing a different task mechanically so to speak with how the electron beam is aimed and timed. If it's a LCD monitor, it will first convert that signal to its native resolution, then display it as it would any other resolution (though of course it won't look exactly perfect if it's not at its native resolution).
