Maybe try this with your VT60
Use your High/Low RGB settings first, be mind full of your odd points (15,25,35 ect) that there is no detailed adjustments for. Try and balance out your 10PT with your 21PT grayscale.
Also run your 90% to 110% windows to see where your RGB starts to drop off, the drop off in your RGB should not start until about 102%.
Now use your detailed 10% and 100% settings to set your 100% reading, then adjust your detailed RGB. Always be mind full of what those detailed adjustments are doing to the RGB H/L and detailed adjustment, pay close attention to your 100% reading but without changing that point.
Now go to your CMS/Gamut settings.
Stay away from adjusting Green in your RGB adjustments, and I would also stay away from adjusting your detailed Gamma settings.
Of-course your gamma line isn't going to be flat but still close enough.
Use a non apl window 5% to 11% window, use off-screen mode for your meter between 10" and 18". The reason for using off screen mode is to get a bigger read area and a 3 times measure average read per read.
Once completed you should have a CR of between 20K and 24K, if you set your min light and max light settings correctly.
Added, The chart that DrFaxe made for a 21 point grayscale and the different's between that chart and a 10 point grayscale is a good example of how a 10PT GS can look good on paper but if you look closer at a more detailed 21PT GS its not very good. And I doubt the gamma chart is taking into account the odd GS points, so of-course this can cause issues with the final out come of a calibration. That's why I suggest using the H/L GS controls to even out the odd points with the even Points.
Yes your CMS can help but it is very limited to using only outer 6 points (RGBCMY).
iow, for a best my display can be calibration you need to go out side of your displays controls. The more color points you can use the better the fine details are going to be.Edited by sillysally - 11/25/13 at 9:44pm
