I have a Dell Inspiron N5030 with a video problem (NOT the same N5030 as my question asked yesterday). My LCD screen video basic desktop display is jittery with the color set to true color. If I set on high color, neither the LCD nor the external monitor displays any video problem. If I set on true color, the LCD display is slightly jittery but the external monitor display is normal. Windows 7 Home premium 32-bit tells me that my monitor.sys driver is up-to-date. Could this possibly be an LCD cable problem please or is it most likely to be the LCD itself? Thank you.
