Hi,
I've been following the stickied calibration guide with hcfr and a colourmunki iDisplay I recently bought to calibrate my computer monitors. I'm using the avs709 test patterns, hcfr window set.
Although I'd done a movie mode calibration using just the test patterns a few months ago, I've redone it all using the colourmunki/hcfr and taken screenshots of the various graphs. Since they're pretty large you can view them via this dropbox link.

Bear in mind I've adjusted the scale on the RGB, so the graph looks a lot bumpier than it really is, the range is 0-5. Also the pre/post calibration hcfr chc files are in there if anyone wants to take a look.
The above was obtained with the settings

I've used a target 100% white cd/m2 of 80 for viewing in a dark room. I have another calibration under standard that uses 110cd/m2 for general viewing.
As far as I can tell, everything is reasonably close with the exception of the red and green colours which are offset inside a little. As the colour space setting for red shows, if I increase the red value to get closer, this causes the red Y value to increase and there's no green/blue available to reduce back to the target 16.9. I'm guessing the inset red is also the cause of not been able to get green any closer either.
I adjusted as best I could to get all the lines hit the d65 spot and Whilst I'm not sure I'll notice too much different if I hit the exact R/G values, thought I'd ask in case anyone has any suggestions or can see anything I've messed up (first time calibrating with hcfr so that's quite likely  )
