Do Developers Really Need a Second Monitor? 1002

jammag writes "It was an agonizing moment: a developer arrived at work to realize his second monitor had been taken (given to the accounting dept., to add insult to injury). Soon, the wailing and the gnashing of teeth began. As this project manager recounts, developers feel strongly — very strongly — about needing a second monitor (maybe a third?) to work effectively. But is this just the posturing of pampered coders, or is this much screen real estate really a requirement for today's developers?"

      Oh yes! I love dual screen monitors. 2x22's at work and at home I wanted dual screen so bad I have a 24 and a 17. Proven to make workers more productive. Not sure if it's because they can work on both or keep work on one and Slashdot on the other. That way work occasionally comes in to peripheral vision and reminds them they are supposed to be working.

It's especially nice to be able to view the entire protein one screen, and all of your data and/or literature on the other. It's also nice when running VM or connecting to the Windows Citrix Server on one screen and doing real work in Linux on the other -- it's almost like having two computers.

    My opinion is this is largely a consequence of how the Maximize functionality works / has worked.

    The ability to half-screen maximize by dragging a window to the left or right side of the screen helps quite a bit -- this is in Windows 7 and newer builds of Ubuntu (IIRC).

    My typical reason for wanting a second monitor is the ability to maximize documentation/help stuff on one monitor while the other is reserved for the code itself. I find I work much slower on, for example, a laptop where I constantly have to switch back and forth between different windows to get at what I want.

      • Make the grid size reconfigurable instead of the fixed 33%,50%,66% sizes (ie. Maybe an even better option is to retain the 2x3 grid, but allow the user to specify how big the grid blocks are.)

    If the company wants the programmer to be more productive they'll give them two monitors. That way they can run the application on one screen, or documentation, and have the IDE open on another. Having to toggle between windows while cutting and pasting, or looking for fine detail differences between output, and code is a real real real suck ass aspect of coding.

    This could of course be fixed by giving them a larger monitor and fixing the way maximize works in the OS.

    It's not just developers. I originally discovered the benefit of having a second monitor at a coding job in college - one screen for code, another for a browser to test the code and read documentation, etc.

    After that, I bought myself another monitor for my desktop. Two came in great handy for translation - one monitor for source document and reference works, other monitor for your translation. It came in handy for reading electronic documents and taking notes/outlining. It's great for any job where you deal with lots of text, and need to be able to compare different documents, synthesize them, etc.

    I'm now up to three. There are diminishing returns, obviously; the third isn't strictly necessary for me, but highly convenient. Any more than this would be tought for me to use effectively, though I suppose a square arrangement of four could be useful for some people.

    I would go crazy trying to develop on only one monitor. In fact, I could use a third, but it's not worth getting a new video card for it.

    Also, from the article, the idea of a second monitor being a "perk", comparable to a free lunch, is stupid. A second monitor is a tool to do work that directly affects productivity. A free lunch is just another way to get paid. The two are completely unrelated.

    On the other hand, if you can't gain enough productivity from a second monitor to justify its purchase, there is also something wrong. My second monitor easily saves me 2-3 minutes of tabbing a day, minimum. Most good coders cost at least a dollar per minute. That's say just $2 per day, so a second monitor pays for itself in 100 business days or less.

    So a company that won't pay for a second monitor if you want one is li

When I run my tests on the single montior, I have to just run the tests,then wait until they're finished to look at the log file.
  • I focus on one thing at a time. I'm an old fashioned compulsive maximizer. More screen is not always better. I've seen people use multiple monitors, they have to micromanage the windows themselves. I doubt there is a difference in productivity with two monitors. More stimuli does not necessary mean you'll perform better. I like to do one thing at a time, keep all alerts, email alerts and anything that could pop up off. It keeps you in the zone.

  • It's not an absolute requirement, but if you do a lot more than coding (writing documentation, tailing logs, remote desktopping into Windows machines, etc.) it's certainly useful.

    Or how about debugging, one for output, one for code?

    Or just to read the specs of your new product in one window while designing the interface or GUI in the other.

    There are times when there's no need for a second monitor. But there's also a lot of times when two monitors simply help a lot. Plus, considering their cost, it will have paid for itself when it saved you about 5 hours of work. It simply is a no-brainer to have one.

  • So, apparently, says the research to come out of Microsoft's User Interface group. [microsoft.com] Quoting:

    The research study required users to complete several different tasks, switch from one task to another, and remember data. None of the study participants had used multiple monitors before.

    The first study revealed that the users' productivity increased by 9 percent. Further studies showed even greater increases - at times up to 50 percent for tasks such as cutting and pasting. Mary Czerwinski, the VIBE research manager, is excited about her group's discoveries, asking, "If you're able to squeeze 10 percent more productivity out, do you know how much money that will save?"

    One of the user studies that the VIBE group did required users to navigate through a series of doors, and then back their way out. They wanted to test the user's ability to remember a series of actions on a small display versus a large display.

    "The interesting thing is that they try to get it right. We found that memory capability is considerably improved on a big display over a small display. There's something about engaging the peripheral vision that improves your spatial memory of what has gone on," said Starkweather.

    They've also found that additional monitors greatly help women in computing. See same article.

    My own experience with this is that I perform better when I can get more pixels in my field of view, regardless of screen size, as long as I can read what's going on. An additional monitor improves both constraints. In contrast, when I have to work with a laptop and an 800x600 display, it's like sipping information through a straw. This is regardless of other factors like network bandwidth. Your mileage may vary.

    The answer isn't universal -- it depends on what your development target is and how your tools work.

    Here's a specific example. Know when having two monitors was awesome for developers? Back in the days when one of those monitors was attached to a VGA card, another to a MDA card, and you were debugging full-screen graphical apps under MS-DOS. You could run the full app on the VGA screen, but run the IDE and debugger on the monochrome screen on the same system at the same time. There was no way to do anything comparable with just one monitor.

    But if you're programming for the web? Or for an Arduino? Or for an Android phone, testing/debugging real hardware? Some individual work habits may make some developers more productive with more screen real-estate, but not due to anything inherent in what they're doing.

  • If you've never worked with dual displays, well, you can't miss what you never had.

    In fact 3 monitors are probably ideal. Development, as a mental process, involves a lot of switching between medium-term and short term views. It also often takes context switching. I prefer the development screen in front of me, the api descriptions on one screen and the details pertaining to the context of the project on the left. I like having 3 screens when I write code for the same reason that I like to do math on the dinner table. Bringing multiple contexts together takes a lot of space.

    I can't believe a decent developer comes cheaper than $100K/year in the US, counting everything. A decent, perfectly usable, monitor will run something under $200.

    That means that, if the corporate budget was sane, providing the extra monitor would be worth it if it improved productivity by 0.2%. If taking the monitor away cut the developer's productivity by one half of one percent, it's costing the company more than it's worth within five months. If the developer's claim of reduced productivity is even slightly true, that's a real false economy.

    The morale effects alone will probably drive down productivity by full percents. When the developer thinks the company isn't willing to spend $200 to keep him working as accustomed, the developer is likely to get a feeling that the company doesn't care how productive he or she is, and will lose motivation and an edge on hard problems. When management takes the attitude that the developer is whiny because he or she is trying to hang on to his or her tools, bad things are going to happen.

    With the time needed to adjust workflow and habits to the reduced screen estate, as well as some time complaining and trying to make a business case, it's likely the developer will lose four hours very fast, and there's the money saved from not just going out and buying a monitor for Accounting.

    People may not want to work for a company that does things like that. Does management have any sort of handle on how much productivity staff turnover costs them? And, of course, if the developer has any substance to the claim of reduced productivity, even in the sligh

      I agree with your sentiment, but there are other considerations to make in a business setting. As far as simple costs go, the sticker price on another monitor might be $200, but there are often large costs beyond sticker price in the corporate world. The purchase has to be requested formally, then approved, then ordered, received, and installed. The real cost in accounting, paperwork, and labor could be a surprisingly large percentage of the final cost. Granted, there's almost no plausible final price at which this isn't a worthwhile investment if, as you say, the developer realizes even a fraction of a point in productivity gained, but never forget that nothing is cheap in business.

      The other thing is that sometimes people can be irrational weasels. If getting a new monitor for this guy inspires someone from accounting to request one for better spreadsheet management, and ultimately everyone down to the mailboy starts thinking they need dual displays, that's a lot of money and annoyance in the short run in exchange for relatively small productivity gains in the long run. Then you factor in the relatively small possibilities that some people who get more screen space will therefore require more desk space and thus better furniture to accommodate it, which could lead to people needing more square footage, etc.

      And god help the company if someone decides that they don't need a new monitor, but someone else got something cool so they want a better chair. Some people react irrationally to the perceived status inequality behind equipment purchases. It's pure monkey brain at work, but it creates a lot of tiresome whining and bloated spending sometimes.

        then it's up to the company execs to grow spines and be the objective leaders they're supposed to be. this requires them to have some knowledge of the subjects they hire people to deal with...not everything, but at least the generalities. in this case they should know enough before oking inter-department

    • Sometimes the guys with the asset list in account sections think it is perfectly reasonable to lift what they need from another area without going through the departments that paid for the stuff - in their eyes accounts own everything.
      I'm lucky I don't deal with that now, but previously had to deal with account bastards so pettily evil that one demanded I rush out and buy a specific expensive printer for him with my own cash and then demanded afterwards three competing quotes and a written justification of
