How Big is Too Big?

Cw - I agree that most people sit much farther from their screens than the THX guidelines recommend. I sit at 9 feet from a 60" screen, so I too am farther away than the guidelines, but probably closer than most viewers.

I find the distance at which I can start to see pixilation, then move back a couple feet. That maximizes the impact of the screen's size while not allowing me to see the limits of the image's resolution.

Of course, the higher the source resolution, the closer you can sit without seeing the limits of the image's resolution. This may explain why people sit so far from their screens - they developed their habits with low resolution images, which require farther viewing distances to avoid seeing the limits of the image's resolution, and they have not adjusted their habits as high resolution sources have become more common.

You really need to ask HER. In Texas, they say size does matter.

Re Ask HER

I just asked my wife, and she thinks I sit too close to the screen.

I have just asked her to sit at the most comfortable distance from our 40" HDTV. Using a tape measure, this is +/- 9 FEET!

I nonetheless look forward to an array of 46" screens approximately 3 feet away.
