If I could find a 16:10 (3840x2400) 17" panel that I could retrofit into my laptop, I'd go for it.

If you're 2' away from the monitor, a 24" monitor subtends an angle of 60 degrees -- 30 degrees off-axis in each direction -- which is reasonable. A 50" monitor would be something more than 90 degrees. > While you can of course move your eyes to focus on other parts, you may > find that the small pitch text you work with in your code editor that > works great when it is front-and-center, now is too small when it is off > in the far corners of the screen. > > There is always good use for more screen space, but given the above, the > high resolution across the full 39" inches might be wasted.

Multiple screens have disadvantages, though: 1) The gap between the screens 2) A typical 2-monitor display increases horizontal resolution, but not vertical 3) The dot pitch is the same as with a conventional display If I had a screen with twice the resolution, I might not be able to use the 6x10 fixed font that I currently use in emacs, but 7x12, 8x13, or 9x15 might be perfectly usable. They would be smaller than 6x10 on my existing 1920x1200 displays, but more detailed, making for better readability. In practice, I'd go for the smallest font I could halfway comfortably read, and just hope that I don't lose the remaining nearsightedness in my left eye too quickly (my eyes differ a fair bit, so I use my left eye for near vision and my right eye for distance vision). -- Robert Krawitz <rlk at alum.mit.edu> MIT VI-3 1987 - Congrats MIT Engineers 5 straight men's hoops tourney Tall Clubs International -- http://www.tall.org/ or 1-888-IM-TALL-2 Member of the League for Programming Freedom -- http://ProgFree.org Project lead for Gutenprint -- http://gimp-print.sourceforge.net "Linux doesn't dictate how I work, I dictate how Linux works." --Eric Crampton
