Kevin Wines, Image Technology Director at THX, Ltd., talks about the future of display technology in the home and commercial cinema, including increased spatial resolution (4K, 8K), increased temporal resolution (high frame rates of 48 and 60fps), and how these advancements might be delivered to the home. He also discusses 3D, including the 3D broadcast of the Olympics, online distribution versus physical media, THX certification of displays and content, answers to chat-room questions, and more.

Last week's poll question asked if your home theater's AC power is protected from things like lightning strikes and blackouts. This week, I'd like to know if you have taken steps to optimize the AC power to your home theater. Such steps can include installing a dedicated circuit, establishing a common ground, and using a power conditioner, such as the Furman IT-Reference 20i pictured above.
If you use a power conditioner, have you noticed an improvement in the audio and/or video performance of your system that you can reasonably attribute to that device? Inquiring minds want to know!

MIT postdoc researcher Gordon Wetzstein and Ph.D. student Matt Hirsch explain a new glasses-free 3D flat-panel technology they are working on at the MIT Media Lab. Conventional stereoscopic displays show two views (left and right eye) in a narrow viewing area, and all viewers see the same perspective. The new display shows many perspectives across a wider area, providing each viewer with a different perspective, much like a hologram. The new display combines several LCD layers, directional backlighting, and sophisticated processing to achieve its remarkable result. This isn't going to be a commercial product any time soon, but it does point the way toward a more realistic 3D display without needing those annoying glasses.

In this week's episode of the Home Theater Geeks podcast, SurgeX engineer Martin Dornfeld talks about AC power protection in home theaters, thankfully without the voodoo and hype I've heard from others in that field. Our conversation lead me to wonder how many of our readers have taken steps beyond cheap surge-suppressor power strips to protect their precious home-theater gear from power spikes, lightning strikes, voltage sags, and power failures.
How about you? Have you installed a voltage regulator, surge suppressor (other than a cheap power strip), lightning rod, uninterruptible power supply (UPS), or other power protection? What have you done in this regard and why—or why not?
Note: This poll question is not about power optimization—I'll ask about that next week.
