When I finally get around to building a house and then, you know, installing a TV inside it, I’m going to be seriously thwarted by the home entertainment options. LCD, plasma, projection, I don’t even know where to begin. Happily, I won’t be building a house for a few years. And, frankly, some other people will do the actual building.
In the meanwhile, screens of all types keep getting bigger and bigger. At the big consumer electronics show, CES (here’s a bunch of Flickr photos of the event), Matsushita has just released a 103-inch plasma screen. That beats Samsung’s largest model by, uh, one inch. Of course, it’s ain’t the size of the wave…

I don’t know. I’m a little under-whelmed by the whole big screen thing.
The resolution is the same on obscenely big screens, pretty big screens and average guy screens. The net effect is that the bigger the screen the bigger dots and you have to sit further away from it otherwise it gets pretty distracting.
If you family room is 42 feet long then I suppose a 102 inch screen is just the ticket.
Of the technologies available, I’ve been most pleased with my projector.
The issues of going from recorded TV and movies to DVD and back to display are ridiculously complicated. The amount of processing involved is quite remarkable – downconverting, compressing, frame rate conversion, widescreen conversion, analog-digital, upconversion… I wrote a post about it recently in my blog.

The brief summary is you may be disappointed with a regular TV image when displayed on a fancy LCD TV.
