The vertical viewing angle is smaller and optimized for
viewing from ABOVE or BELOW. It's called six-o'clock
or 12-o'clock viewing position. You get either, not both.
A TFT will be much better than a DSTN display off angle.
And TFT technology as gotten much better in recent years.



Do they even make DSTN displays for laptops anymore? I've got a couple
of fairly low end machines that are TFT.
