It's not the cable because this uses displayport, not LVDS. LVDS can do this - displayport is an all or nothing protocol. It's not the graphics since this machine has integrated graphics in the CPU - Intel graphics doesn't die like the junk overpowered undercooled AMD/NVIDIA chips have for the past nine years. It's the screen. Replace LP133WP1 and best of luck!
