This phenomenon can occur with Philips 107P, 109P and 201P monitors and is normal. Your monitor is using an Aperture Grille, which consists of fine vertical wires to align the electron beams with the phosphors on the screen. To prevent these vertical wires from vibrating and to keep them properly aligned with the picture tube, two horizontal damper wires are required. These are located on one-third and on two-third from the top of the screen. The result is that you will see two very thin horizontal lines over your screen since the two wires are casting a slight shadow on the screen surface. You will find these wires (line) in any monitor from Philips and other brands using the Aperture Grille technology.

Please check with your computer or video card manufacturer for further details.
