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](https://i.stack.imgur.com/Pq4QV.jpg)

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.
