Bias Lighting

[pewternhrata]

I'll try to find the article, but it points out the sole purpose of bias lighting, to reduce eye strain. 6500k at 250 lumens. That color temp and output also blends with a properly calibrated tv. If colored bias is used it degragates the image. Any wall painted with a color, be it blue red or so on, will cast a hue around the tv which is why a grey wall works (also think silver screen for a projector, ideally a pj screen is grey or 'silver')

My walls might be a beigish gray. Still doesn't bother me. I'm not much of a videophile either

Exactly.

In my previous setup I painted the main wall a battleship gray and it worked well. Can't do that in the current place so I have matte dark blue curtains and it doesn't cast a hue when the room is darkened.

I should note the link is intended to show the true benefit of bias lighting and how to accomplish it. Aside from that, use color or whatever brightness you prefer. Have fun with it and at the least, the light will be from behind the screen and cause less glare/reflection.

I use lightstrips from Philips Hue, kind of spendy but all my lights are Phillips Hue now except outdoors.

I actually change the colors behind the display depending on what I am watching and my mood.

I am not certain what it does for the actual movie experience but it add a lot of depth and texture to my fireplace which is where the display is mounted and looks awesome.

Excellent. Ends my idea of bias lighting for our TV and blue walls.

White light illuminated blue and other colors will impact the appearance of colors on the screen. Do you use bias lighting with a colored wall?

Thanks

It will not impact the colors on the screen. All the bias light should do is to relieve eye strain from dark to bright and bright to dark. I usually leave it at white but I chnage it depending on the mood I'm in.
