Need some help Calibrating

I need a little help/advice with an ASUS VG278H 27" 120Hz monitor. The colors seem a bit off, are very "washed out", and everything seems overly bright. I've tried messing with the brightness/contrast but without some sort of guide I'm likely to make things worse before I make things better. I've never calibrated or done anything except very slight adjustments to any monitor. However this one needs it.

I was hoping you guys might point me in the right direction to some software or hardware I can purchase, or some procedure I can follow to try, or a website that you might recommend that I can read and learn how to get my monitor adjusted properly.

Thanks for any help and advice :)
 
You can go a long way with a colorimeter and intelligent use of good free software, such as HCFR, and dispcalgui.

For a colorimeter, the i1display pro is an excellent piece of technology.

For a bit of background, see this, and the intro in this post (some of the material in Curt's guide isn't applicable, since that is geared towards a 16-235 RGB setup, rather than a 0-255 PC RGB setup: in particular, the use of pluge patterns to set the black level).

The basic workflow is to use the monitor's controls to achieve as accurate a grayscale as possible, while maintaining an acceptable contrast ratio. HCFR is useful here, as it allows you to make real time measurements while making these adjustments.

After this step, software like dispcalgui can really fine tune the grayscale, as well as the gamma.

You can set it up using a website like "lagom" which gives you test images etc. Next thing after that would be a colorimeter, but a good one will cost half as much as the monitor.

TN can have perfect color reproduction and calibration, just that you are viewing it off axis. :)

still, if it have crap greyscale/gamma, calibration can help.
 
It's TN so it can't be meaningfully calibrated.

Not true. It should be noted that the Asus VG278H's color presets are pretty poor. Calibration can help a great deal, but you won't be able to match IPS color consistency due to poor viewing angles and the extremely grainy matte coating.

If you want to perform an actual calibration consider the i1 display pro or the cheaper, entry-level xrite colormunki, with the free and open-source software spacediver has already linked. Forewarning: the colormunki is much slower at taking readings than the i1 display pro.
