I remember bias lighting was getting a lot of buzz on A/V forums back in early 2000s. I know this because I bought a fluorescent light bar in 2001 and put it behind my TV. Then I think it kind of faded into obscurity until you started seeing some TVs with built in bias lighting. Sometimes it was color changing and sometimes it was a little more focused on the "effect" of having a blue or green or yellow back light than the fact that it was reflecting off the front wall and creating bias lighting. Bias lighting is supposed to both reduce eye fatigue and increase the perceived contrast of your screen. And with modern technology there are now LED strips that stick to the back of your TV with double stick tape instead of the bulky fluorescent light I used nearly 20 years ago. A quick search turned up this Amazon.com: Bias Lighting for HDTV USB Powered TV Backlighting, Home Theater Accent lighting Kit With Remote Control, Kohree 2 RGB Multi Color Led Light Strip (Reduce eye fatigue and increase image clarity): Electronics which is only $14. I might give it a go.
