In the very near future my development setup will be upgraded and part of the deal will be dual monitors (yay!)
At least one of the monitors, possibly both, will be widescreen.
I've heard of developers using a second monitor, especially a widescreen monitor, in portrait mode. It allows for many more lines on the screen (albeit narrower) and runs a bit like having a long page of code.
Does anyone out there use this and think it's more effective?
I have never given it a try but I would imagine it would work pretty well. I personally like to keep my lines fairly short, and wide screens tend to give me fewer lines of code, so I would give it a try.
It all comes down to personal preference however, what ever allows you to be the most productive and works best for you is the way to go.
For me it's not effective at all. I use IDEs, so in landscape mode I have sidebars to navigate code, navigate project etc.
I have 2 19" monitors currently. One I keep in landscape and one I keep in portrait mode. I find that working on documentation or reading long web pages is easier on the portrait screen. I have used this setup for coding also and find that it does help, however it was a learned habit. lol
Depends how big your monitor is. We have 1 28" monitor in landscape and 2 24" monitors in portrait which flank the big monitor.
Works great for pair-programming!
Since you shouldn't write functions that are longer than a screen, making the screen much longer is a little bit of cheating, isn't it? ;)
Anyway, I found portrait mode not really better when coding, and only with my old 17" widescreen in portrait mode was viewing / editing documents better. With two large screens in landscape mode, You can put two pages on a screen when viewing documents, and have many tool windows open at both sides of the IDE's text editor. So no, portrait mode is not better, unless you have four of them to make up a really large screen (there was a photo of such a setup on a Microsoft blog, but I don't remember where).
There are some applications where portrait is still better, though, e.g. if you have to show a document in large resolution, or if you have some monitor (as in network monitor) running and want to see more lines at once.
I actually have 3 widescreen monitors in portrait mode and yes, it's a fantastic way to work. There's so much less scrolling around and you can fit all your debug / output / reference windows on screen at once.
The problem with using two monitors is that you'll generally be working on one main one and have output (or whatever on another). If you do have two, set it up so that your primary monitor is directly in front of you and the other (less frequently used) one is off to one side. I find that to be the best way to use a dual-monitor set up as it reduces RSI from being permanently twisted to look at a particular screen.
Additionally, there are some programs available to provide virtual screen splits which I've fund very useful for large/widescreen monitor setups.
[edit] ..and yes, you should write functions short enough to fit on a single page, but being able to see more functions at any one time can often make development easier in my experience :-)
[edit2] Running Visual-Studio-esque IDEs in portrait on a widescreen monitor is fantastic when it comes to debugging compile errors as you have more useable space to see code and errors at the same time. I suppose you could argue that if you compile regularly enough though, you shouldn't see that many errors at one time? ...but who codes like that? ;-)
It depends on witch IDE you use if any.
Microsoft Visual Studio likes to take up a lot of the width of the monitor with its “toolbox” and “solution explorer”, so it find it works better on a landscape monitor. As it will not let you undock an editor window, you could not even drag a code editor to a 2nd monitor that was in portrait mode.
Also consider how your customers are most likely to have their monitors set up, you may wish to write any UI code with the same setup so you get a feel for what the application will be like to use.
It's not silly but a matter of opinion. A widescreen in portrait is very nice for writing code, code width has never really been an issue, and being able to see more line of code on the screen is always nice.
The other reason to put a widescreen in portrait is so it matches the height of your other monitor, for example a 30" widescreen next to a 22" widescreen in portrait have close to the same height.
I can't imagine how that would speed up productivity. In my opinion, it is always easier to scroll up/down than left/right.
It all comes down to your preference.
I just have one big monitor at my home office.
I tried it once. I didn't like it. I usually have an IDE and IDEs are perfect for widescreen. It's faster to jump around if you can see your function list on the right, file list on the left, etc.
Also, I try to keep my functions small so this usually isn't a problem (I have dual 24"). If your functions are reasonably small, and you have widescreen, you can show two files side by side which is often more useful. Some editors allow you to split the window and scroll to two different parts of the same file. This is also very useful is far better than having 100+ lines on the screen. With my settings, I have 60 lines per screen on an editor. If I split the editor, I can see 120. If I do it again on the other monitor, I can see 240. That's quite a bit of code and generally only useful for very different parts of it.

If you are working with print material, yes, as for source, why not full screen your IDE and close the task panes you do not need?
I find portrait is only useful to me if I'm working on a web site, being able to see the entire page at once helps.
At work, I run my primary monitor (secondary is the laptop screen), in portrait mode. I really like it. I've become spoiled to seeing more code at once. I don't find that it encourages longer methods at all. Occasionally, I run across code that is a bit too wide since the IDE sidebars cramp it a bit, but I largely use Eclipse (Rational Application Developer, but Eclipse-based), so s quick double-click maximizes the code window, and it's very useful. Another double-click and I have my sidebars back.
I also find it a very useful orientation for my email.
I recommend it highly.
Portrait mode widescreen monitors work very nicely for edting code, thank you. However, some monitors have poor viewing angles on one dimension, which would usually be vertical but becomes horizontal in portrait mode. This can make the colours bad or unusable if everything isn't aligned correctly.
If you're working mostly with text (as most programmers or other technical folks do), or even documents, then portait mode is much more valuable. In fact, the general trend in displays is all the wrong direction: aspect ratios are squishing landscape displays to a mail slot to better fit the format of movies. Personally, I have never watched a movie on my computers (laptop or desktop), and I'm not about to start now - that's what I have a TV for!
In reality, vertical pixels are the most valuable asset in computing - do whatever you can to get more of them - you won't be sorry you spent the money! I won't even buy a laptop with less than 1024-1080 vertical pixels, since that's the minumum required to display a full page PDF at a readable resolution, and (much) more is better. (Since PDFs make up a large portion of today's online documentation/manuals, that's a very big concern.) You should only think about width after you've got enough vertical pixels.
What I really want is a 15.4" or 16" laptop with a portrait screen - these should still be wide enough to package a full-size keyboard into the base - a FlyBook-style pivot arm would be nice, but isn't required.
I found understanding the intent of related functions are easier when you print them first on paper than understanding them directly from screen, never fails, why? Because you can easily review many lines of code at one glance, no need for incessant scrolling.
The same thing with monitor oriented in portrait mode, you can easily understand the intent of multiple related functions, re-factored or otherwise. But don't let having portrait screen be an excuse to write a function with many lines.
Writing this on stackoverflow using portrait screen :-)
I can easily see many posts at one glance :-)
I would say if the monitor is large enough you don't need portrait mode (24" and higher) for writing code.
If the monitor is smaller than that, then portrait mode is preferable.
Ideally what you would have is a single 30" (2560 x 1600) as widescreen to work on your code along with utilities comfortably open nearby and a second smaller monitor nearby to preview the results (I am speaking about web coding specifically here but it would probably apply to most other coding as well - a screen the size of your target audience's screens).
The 30" screens have really come down in price now so it's probably worth the jump up. A 24" screen does have the advantage of significantly larger text at default font sizes. The text on 30" monitors can get to be a bit of grind unless you move up to 14pt.
Good luck.
