Is there enough difference between XGA, SXGA, and UXGA to be significant on a 15″ notebook LCD display?
Yes, you will definitely see a difference between UXGA and XGA on a 15″ display–the higher the resolution, the better the clarity of the image. However, speaking from experience, a 15″ display is too small to support a very high resolution such as the UXGA. I believe an SXGA is the maximum a monitor of that size can manage. ** Resolution refers to the sharpness and clarity of an image. The term is most often used to describe monitors, printers, and bit-mapped graphic images. In the case of dot-matrix and laser printers, the resolution indicates the number of dots per inch. For example, a 300-dpi (dots per inch) printer is one that is capable of printing 300 distinct dots in a line 1 inch long. This means it can print 90,000 dots per square inch. For graphics monitors, the screen resolution signifies the number of dots (pixels) on the entire screen. For example, a 640-by-480 pixel screen is capable of displaying 640 distinct dots on each of 480 lines, or about 300,000 pixels. This tran
