During the LCD Monitor manufacturing process, it is not uncommon for one or more pixels to become fixed in an unchanging state which are hard to see and do not affect the display quality or usability. The operating temperature shows the safe temperature range (from minimum to maximum), within which the display will function flawlessly.When you notice screen abnormalities like distortion, clarity, horizontal or vertical lines, color fade so forth, it is always a good practice to isolate the monitor by running the integrated Diagnostics. Grade A - Good condition, no noticeable marks on the screen, may have a dead pixel (as might a new screen) may have minor cosmetic marks on the casing.
