Here's a link that shows some of their work on ruins and unfinished buildings. Fascinating!

@Iulia Popescu That is exactly my point. Depending on the quality of the content, the distance from the viewer to the screen, and the importance of a higher resolution, 4K may not be the right solution. Having said that, it may be the best solution, too, using the same criteria. 

I use 4K monitors for work, but I have a 1080p television. I sit less than two feet away from my 24" monitors, and over 12' away from my 60" television. Content aside, the potential visual acuity justifies 4K for my work monitors. As you pointed out, this is a big benefit for content creators, who's work could be presented in a myriad of applications with widely varying viewer distances, ambient light, etc.

Thanks for the post, and for sharing the math behind the formula. Also, the Skittles analogy is a nice touch.

Ask yourself this question. 4K, por que?

Despite some excellent marketing efforts, there may be little reason to use in a given application.

Here's a pro tip from the Southwest where we run a vaporizer every night. Use distilled water to avoid the build up of mineral deposits that covers everything like dust when you use any other type of water.

"...speech intelligibility is not always compensated by just amplifying it." In fact, depending on the acoustics of the room, it may just amplify the problem. I had a client with a small multi-purpose space who tried to use it for presentations. He couldn't be understood due to the long reverb time, so he tried using a portable system. It only made the problem worse. After we installed wall and ceiling acoustic panels, he could do presentations unamplified with better speech intelligibility than he had ever experienced in the room. He was delighted with the outcome.

AI and voice tracking are great for automatically adjusting the field of view of a PTZ camera. When the client can't afford multiple cameras, it is the best alternative.

It doesn't solve the problem of having all remote attendees individually framed, while the local attendees in a conference room share a camera (or two). Remote attendees miss all the visual cues of the local attendees not talking. One way to solve this is by using a multiviewer in the signal path in-between the cameras and the AV Bridge. This can be done with a dedicated multiviewer, or with a combo device. This isn't perfect, of course, but it is another option. 

What other creative solutions have people tried?

It changed Asimov's third law!?!?!?! For those unfamiliar, here is the list. This pushes every robot story into a Frankenstein's monster framework.

The Three Laws of Robotics

1.A robot may not injure a human being or, through inaction, allow a human being to come to harm.

2. A robot must obey the orders given to it by human beings, except where such orders would conflict with the First Law.

3. A robot must protect its own existence as long as such protection does not conflict with the First or Second Laws.
