I sometimes hear that the best place to sit in a commercial theater is in the vertical and horizontal center of the screen - meaning your line of sight is exactly to the center point of the screen. Does the same rule apply in a front projection-based home theater using either LCD or DLP technology? As you can see this is kind of an HT design question - I ask because I'm trying to determine how high on the wall to mount the screen as well as what height the viewer should be seated at. But, I see some websites where it looks like the "sweet spot seat" (which is in the front row) might yield a sightline below the vertical center of the screen, prompting me to ask this question. I know with rear projection TVs, viewing angle is very important so you're seeing the best picture, but I'm not sure if this holds true for front projection based on LCD and DLP technology. I'll probably have two rows of seats in my HT and at least one row (the back row) would be on a riser, but I'm not sure if the front row should be raised too. If it helps, assume a basement HT with at least 8' ceilings. Thanks in advance for your comments.
