Yes, you can hook it up and use a lower resolution. You will find that it looks really pretty good, even with a lower resolution. If not, THEN buy a new graphics card
If the picture you find is the same dimensions as your screen it shouldn't be blurry or pixelated. For example, if you have a 1920x1080 screen resolution and you look up a 1920x1080 picture, it will not be blurry. If it is, the picture is too small or your personalization settings are incorrect.
Yes. It depends on the screen resolution (eg. 1024x768) for a better picture and the aspect ratio (eg. 16:9) which supports the quality of the picture
That would be "screen refresh" or 60hz for example. Resolution is the amount of "Pixels" or dots you can see. It would be similar to taking a "Normal" picture in a camera and taking a "High resolution" picture. The smaller the number, 640x480 the less pixels, pictures would not be as good looking. The larger the number, 1920x1080 the more pixels. The picture would have better detail. Kinda like the difference between watching a HD movie on a normal tube TV and watching the same movie on an HDTV.
You're talking about lines of video resolution, or generally, the amount of picture detail. Of course a 1080 (I or P) is going to offer greater detail, but you also need to keep in mind the original picture source and the system used by which it was recorded.
Resolution is picture resolution and vertical resolution is number of pixels on y axis.

If the picture has lower resolution than the screen, it stretches the picture to fit the screen. The screen resolution is 320x240, to check a picture resolution go options > view details.
Image > Image Size
The picture capacity of this and other modern digital cameras will depend on the resolution you select for a picture or pictures. High resolution pictures will (naturally) take up more memory than the same picture taken at low resolution.
The image resolution of a picture is broken into pixels. The amount of pixels in the picture depends on the size of the print. There are approximately 100 pixels per inch in a picture.
Image is a real world picture while graphics is a computer generated picture
You could tell because low resolution makes for a pixelated picture, and high resolution settings, you cannot tell.
