Hi all,
My first post so please go easy.

I have gone and brought myself a Eye one display 2 and set out to have a crack at setting up my display. I used the greyscale and colour calibration for dummies and found it fairly straight forward. I seem to have most of my RGB values close besides the blue but they dropped when i changed contrast or gamma settings before i went to bed ill re run it again tonight when i get home and get them back up to scratch the blues seem to be running a little low and the red jumped a bit. but i'm having problems with gamma its way out. On the TV Panasonic 50G10A i had the gamma set to 2.2 but it was definitely not displaying at it i have attached the graph below for people to have a look the dotted line is when i had the tv set to gamma 2.2 the solid line is when i set the gamma to 2.5 and its still short of the real 2.2 on the graph. Am i missing something in the guide it says if your gamma is over that sweet spot of 2.2 that i will need a gamma booster but mine is under so what does that mean. I don't have a higher setting that 2.5 on my TV to try and get more gamma to at least get it close to 2.2.

Or is my gamma out that far because my blue values have dropped around 7 - 8% and my reds up around 2%.

Any help would be greatly appreciated, i spent around 3 hours on it last night only to find when i did my last settings after altering a few things that my RGB values were out again would this be affecting my gamma.

here are my graphs
cheers

Lets try again sorry Updated The Graphs

Can't view the graphs. Photobucket says the images have been moved or deleted.

Have just updated the graphs.

Thanks

Everything looks pretty good. Your gamma's a bit high in spots and low in others, but other than some sort of high end video processor to adjust that along the graph, there's not much you can do.

More importantly: How's it look now compared to before?

Looks pretty fantastic mate, i just notice on some darker scenes like i am legend i loose a bit of shadow detail and the blacks could be a bit blacker,, Is that to do with the Gamma being out?

Im running the contrast at on 40 right at the top end of the 30 - 40 ftL recommended in the guide, If i drop contrast to say around 30 and re- calibrate the display will that affect the gamma levels at all?
