gamma correction for lcds

have you noticed that no matter what you do with the windows "color correction" utility in vista or W7 the look of the monitor has something left to be desired ?
sadly , what can be achieved with that utility is severely limited .
the proof of this was trying it out on a '31 led back light lcd ... uuuggghhh .
the blue is very "hot" and does not "track" with the red and green . it actually did not cut off (think towards black) ... this made a slight blue "wash" over the whole picture .
(i have a couple of decent monitors for photographic work and my eyes see this readily)

here is some information and testing that can be performed .
this helps one to understand what the shortcomings of the windows *correction* capabilities are :

more information can be had by exercising the google-fu with "monitor contrast color correction" .

there are a few *free* programs available that allow better "color correction" or "fine tuning" of an lcd .
one of the easiest to use is "quick gamma" :

the page explains how it works and the difference between the versions for vista and W7 .
get the program here ;

there is one item that is not mentioned ... the newest version of the required C++ visual library is missing a required dll . the way around this is to use the 2010 flavor :
32 bit : https://www.microsoft.com/en-us/download/details.aspx?id=8328
64 bit : https://www.microsoft.com/en-us/download/details.aspx?id=13523

after installing the program it took me about 10 minutes to adjust the rgb gamma tracking ... the improvement is definitely worth the effort .
if you use your monitor(s) for photographic work this program is a must ... unless you use a commercial program .
