What exactly do you mean by ghosting?

Wow. That's well on the way to doubling the cost.

I generally refuse to mess with beta versions of anything, which
means I will have to wait.

Ah, I see. I had assumed that the LCD display must be a fast-switching
design for shutter glasses. Wonder how they produce oppositely
