Short summary tied to the thread: reports the right side of the laptop LCD is completely black, and correctly pointed toward a hardware-only fault. The symptom and a working external output localize the problem to the laptop display subsystem (the panel, its controller/T-CON, the backlight/inverter or the LVDS cable/connector). Below are safe, practical next steps and a short software workaround for immediate use.

Hardware checks (safe sequence)
Power down, remove battery and AC before opening. Do a flashlight test first: angle a bright light at the dark area with the panel on; a faint image means the backlight or its driver is dead, while no image at all suggests column/driver or panel damage. Inspect the hinge area for frayed/repeatedly flexed LVDS cable and reseat the connector at the panel and motherboard only if comfortable. Note whether the screen uses CCFL (inverter board present near hinge) or LED (driver board); replacing an inverter/LED driver or the whole panel is the usual repair. If under warranty or unsure, stop and use a repair shop.

Software/workaround
To avoid the unusable right strip, create a smaller working desktop: lower the display resolution in the OS, or use the GPU control panel (Intel/NVIDIA/AMD) to set a centered/underscanned resolution so the image does not stretch into the dead zone. That keeps the laptop usable until a hardware fix is done.

Have you checked that one of the backlight bulbs hasn't blown or has stopped working. Try to run it onto an external monitor, just to check that you can see the whole screen, then we can rule out any problem with the actual computer and limit it down to the VDU on the laptop

Well then, it looks like your inbuilt monitor is either broken or the backlight has failed. Have you dropped it recently or has it received a heavy blow or the like?
Also open up the laptop and have a check that the backlight is on one piece and hasn't broken/blown/dirt in the way.
