new screen or inverter for dimming screen

[kmh99]

Hello,
The bottom right of my Dell XPS 15z laptop has dimmed a greyish tone. Which makes it difficult to read anything in that area. The rest of the screen is fine maybe a little less sharp. Would my best bet be to replace the lcd screen or inverter?
Thank you.

Try resetting the monitor's settings to factory default.
