My setting is:
2 17" TFT side by side, which gives me a 2560x1024 pixels real estate.
As the TFT price has been steadily going down (my first 17" cost me €1000), I have pondered the advantage of investing on some bigger work area. These are my conclusions:
- If your main work is ArchiCAD modeling, 2 17" 1250x1024 monitors are enough (if there is sucha thing like enough...).
- When modeling, you have the main palettes and the plan window on the left monitor, and the 3d, seccion and navigation palettes on the right monitor.
- Try this: 2 ArchiCad, side by side, where you develope simultaneously the same idea in two different directions. Headache guaranteed, but quite interesting as a metodology...
- When working on final drawings, you take two archiCad side by side (one for each monitor), so you can copy paste from a previous file to the new one.
As for very big screens, consider this:
- Your focus point is quite small. If you are looking at these letters here, you can not focus the one that are two rows up. So, if you manage to program and use proficiently zoom in and zoom out with the keyboard (or a very strange device), having a big visual area isn't that important.
- If you do a lot of work with images, then Dwight has a point. You need to see the most of each image, as close to "real" size as possible. But if your main work is architectural design, you tend to focus on the details, and looking at the whole on a different scale isn't such a handicap. You get used to it, and never miss those big paper sheets again.
- The pointing device: either rat, pen, wand, track, the bigger your working area the bigger your arm movements. It ain't the small finger movement that turn carpal on you, but the wrist suspended arm movement.
In a nutshell: architecture, two 17" side by side is "cheap" and effective.
Of course, you can always try these:
