I think this thread may have more "off topic" posts that any AVS thread that I've read.
The title tells the whole story, or at least it should.
"Video Bias Lighting (SMPTE Recommended Practice
- CIE D65/6500K White Light Only)"
Anyone who is only interested in putting a light behind their display would be better served to look for, or start a thread on that topic. It's a worthwhile topic.
On the other hand it has nothing to do with this thread which is intended to discuss one specific type of bias lighting standard -- SMPTE Recommended Practice
- CIE D65/6500K White Light Only
