The programs work on monitors day in and day out for near untraceable period to time. What is the best position to keep the monitor?

    I find the best position for a monitor to be with the screen facing the developer. – JoshDM Jul 25 '14 at 16:00

The US Government's Occupational Safety & Health Administration (OSHA) provides ergonomic recommendations for computer monitors. There are a number of factors to consider, especially:

Monitor distance:

Sit at a comfortable distance from the monitor where you can easily read all text with your head and torso in an upright posture and your back supported by your chair. Generally, the preferred viewing distance is between 20 and 40 inches (50 and 100 cm) from the eye to the front surface of the computer screen.

Monitor height:

The top of the monitor should be at or slightly below eye level. The center of the computer monitor should normally be located 15 to 20 degrees below horizontal eye level.

  • I wonder what monitor size the height recommendation is assuming. I'm trying to imagine positioning a 30" monitor that way. – Monica Cellio Jul 25 '14 at 14:57
  • I have dual 24" monitors and I have been able to position them as recommended. With a larger monitor I might move it slightly farther back. – M. Dudley Jul 25 '14 at 15:09
  • and for vertical monitor what should be the recomendation? – Emilio Gort Jul 25 '14 at 16:50
  • @MonicaCellio it would depend how tall you are I guess. A 30" monitor is ~3" taller than a 24"; to hit the OSHA recommendation you'd need to have the bottom about 1.5" lower. I have no problem adjusting mine to a comfortable position; but at 6'2" I have the 19-22" monitors I use at work all on stands/books to lift them higher than they would adjust unaided. – Dan Is Fiddling By Firelight Jul 25 '14 at 18:43

What is the best position to keep the monitor?

Since people are not the same (and in many companies monitors are not the same), there is no one best position.

Some people are tall, some are short. Some people see close objects well, others don't. Some people have small monitors, some have large monitors, some have more than one.

Some monitors are attached to laptops, some are independent, some are touch-screens.

The best thing to do is to allow individuals to adjust their monitor(s) (and all other office equipment) to best suit their individual needs and preferences.

You can send around the government/OSHA recommendations as a starting point, but they are just recommendations. Use what works for individuals.

As a developer, this topic is near and dear to my heart.

I would recommend the following:

  1. A non-glossy "matte" screen.
  2. Tilt + height adjustable arm for your monitor. If possible ask for and articulating mount: this

    These are height, reach, and tilt adjustable.

Place the monitor such that:

  1. There is no glare on the screen.
  2. Just out of reach for your arms. This is a good estimate of the distance from your face. If you can reach out and touch the screen without tilting/rolling forward in your chair, the monitor is too close to your face.
  3. Make sure there is lighting at the back of the monitor, this will help reduce the strain on your eyes.

I consider it obvious that human body is made for movement and human vision for relatively long-distance seeing. Thus, I infer that:

a) the best position for a monitor is one which is changing over periods of time.

In this respect (at least) a laptop is ergonomic because it allows you to change its position easily. E.g. you could work one hour sitting, then one hour standing and so on.

Another, less flexible option is to use a "monitor arm". The arm does not allow for frequent change of the position of the screen indeed, but it allows you to try different positions of the monitor until you feel comfortable. In the same manner it lets people of different heights place the monitor in the best position for themselves.

b) a big screen, with bigger scale of displayed content, viewed at a longer distance is better than the opposite - a small screen, tiny scale and short distance.

(More about about bigger scale here: https://superuser.com/questions/698121/bigger-picture-on-a-computer-display).

Ideally the best screen would be a pocket projector with a perfectly stable image and very high brightness. The problem is that projectors are not bright enough to be usable in a sunny day.
