For the LCD monitor, cutout the back and remove the metal shields/ PCB's behind the panel, allowing light to pass through it.
(This step varies a lot from brand to brand. Some brands will have ribbon connections on both the X and Y plane, while some just on the X plane. Fortunately, for my Dell monitor (which was actually a BenQ monitor), the ribbon connector was only on the X axis, so lifting it out of the way to allow light to pass through was easy, without requiring any extra wiring. )

For the panel light filters, there should be some diffusing paper/plastic behind the LCD, 3 sheets (one clear, one reflective, one translucent white), and then a large Plexiglass-like filter. I removed the Plexiglass and everything behind it, only keeping the 3 thin paper-like sheets behind the LCD. Shining a light behind the LCD resulted in an even white glow
