How to properly adjust monitor brightness and contrast? [closed]

This days, it seems that I either go worse with my eyes or some settings with contrast and brightness have been changed.

However, I have been searching now for some tutorial on how to adjust contrast and brightness, and I have found already some, on how to use Microsoft Win7 Calibrate Display Color program, but some people don't recommend it.

My monitor control menu shows settings (which are by default) that contrast is set to 80, brightness to 90 and sharpnes to 45, for which I believe are quite high.

I'm usually every day in front of my PC about 6-10 hours.

The biggest problem is, when the night comes, and I have to read some Microsoft Word document, after a 10-15 minutes of reading, eyes starts hurting.

I'm using ASUS VW198 and Nvidia 9800 GT graphic card.

So please suggest to me which should I decrease: contrast or brightness or both?

Screen settings are really a personal choice. To be easy on my eyes, I personally use contrast at 75 to 80% and luminosity at 20 to 25%.

This break colors, but I find this easier on the eyes. Keeping your work room well lighted is also helpful.

You can use F.lux as said by others to further reduce the screen aggressivity.

On Mac OS X, there is Shades that artificially darken the screen, but I found it more bothering than helpful.

You should check out a free program called f.lux: https://justgetflux.com/

You can set it up to dim the screen brightness (automatically or by pressing: Alt + Page Down) and make it more yellow (non-blue) and therefore easy on your eyes :-)

You can also set it up according to your location, so when the sun goes down, flux adjusts your monitor so it's easier on the eyes. It also makes you more tired than having your monitor beaming light to your face just before bedtime... Which for most, including myself is bad for when you want to sleep.

Try flux, it's one of my favorite must-have free programs for PC :) And I think it works for Mac and Linux as well ;-)

Realistically, you're going to need something to calibrate your screens that isn't susceptible to trickery like your eyes are.

I use ColorVision-Spyder2 for my non color critical work. Your monitor can drift over time, mine do, but having an instrument that can get it back to a "zero" position is very useful, and they're pretty cheap (~50$).

I found a good. practical guide here, hope it helps anyone looking for similar stuff:
