In this case, measure the actual display area for LCD monitors, and measure from edge to edge for CRT monitors. Once you have measured the diagonal length, divide the length by 2.54cm to find the monitor size. The reason for dividing by 2.54cm is because 1 inch is generally about 2.54cm. For example, if the diagonal length is 48cm, then 48 ÷ 2.54 ≈ 19, and the monitor size is 19 inches. ※ This method is used for the diagonal calculation! ◎ Everything is as shown in the actual product, so please take a close look at the photos for the color, shape, etc., before purchasing.♩♩ ◎ As it is stored at home, there may be dirt or damage to the bags, boxes, etc. Car Navigation System Car Protective Film Tempered Glass 9H (Management number 6-44) 26
