Resolution is a very important performance indicator.It refers to the number of dots (lines and planes are made of dots) that can be displayed horizontally and vertically on the screen, and the higher the resolution, the more information can be contained on the same screen.For a CRT capable of supporting 1280x1024 resolution, either 320x240 or 1280x1024 resolution can be presented perfectly (because the electron beam can be adjusted flexibly).However, its maximum resolution is not necessarily the most appropriate resolution, because if the 17-inch display to 1280x1024 resolution, WINDOWS font will be very small, a long time to fatigue the eyes, so the best resolution of the 17-inch display should be 1024x768.
But not for LCDS.The maximum resolution of an LCD is its true resolution, which is the best resolution.Once the resolution is set lower than the real resolution (say, a 15-inch LCD with a true resolution of 1024x768 versus 800x600 in WINDOWS), there are two ways to display.One is the center display, only the 800x600 points in the middle of the LCD will display the image, other unused points will not light up, keep the dark background, it seems that the picture is center zoom.The other is an extended display, which USES every pixel on the screen but affects the display because pixels are easily distorted.So in any case, when selecting LCD, it is important to note that the resolution is not the bigger the better but the better.
