Welcome to a very special thread on AVS Forum, presented by Sony, which provides you the opportunity to ask any questions you like about home-theater projection. Today, from 11:00 AM to 12:30 PM Pacific time (2:00 to 3:30 PM Eastern time), video expert Joel Silver will monitor the thread during that hour and a half for your questions on this hot topic and post his answers on the spot.

To get this party started, we began a pre-event thread inviting AVS members to post questions ahead of time, and many of you responded with some great ones. Joel will begin by answering a few of those up front. Meanwhile, feel free to post your questions in the new thread—the one you're reading now—and Joel will respond to as many as he can.

Because of the functionality of AVS Forum, we decided the best way to conduct the AMA is within a standard thread. This allows people to quote and search for specific posts, but it also means you'll need to reload the page often to see Joel's responses as well any new questions that are posted. Also, because of time constraints, he probably won't be able to answer every question.

In addition to getting answers about home-theater projection, those who submit a question will be automatically entered to win a Sony UBP-X1000ES UHD Blu-ray player. The winner will be selected by random drawing from among those who submit at least one question; submitting more than one question will not increase your chance of winning. The drawing and announcement of the winner will be made at the end of the live session around 12:30 PM Pacific/3:30 PM Eastern.

After the live session has ended, Joel will need to move on to his next project, but this thread will remain open for 48 hours, during which I will answer as many remaining relevant questions as I can. However, I won't respond to questions posted after the live session is over. After 48 hours, the thread will be closed.

If you're confused about home-theater projection, you've come to the right place. What would you like to know about it? Post your question(s) here and follow the thread in real time for the answers.
