I assume there is a tighter value I can set the calibration to - will check the settings tonight.
Greyscale got a B+ because after 6 Autocals - Greyscale looked like Madonna's Pointy Things still. I again assume I can tweat the values in the iScan Duo to flatten the line? For some reason or other, 100IRE kept getting different results with each and every Autocal. (Set was previously calibrated manually - 2 and 10 Point, plus White Balances set to LGs Specs.)
CMS got an A because now it's calibrating with Colour, Tint and Hue, versus LG only giving me Colour and Tint.
Green, Cyan, Magenta and Yellow results were almost at Zero. Red halfway to the 3% line, and Blue over the 3% line, despite 4 Autocals.
Interestingly, turning the Darbee ON, all the Colours stayed more of less the same, but Blue now came down below the 3% line.
What I find annoys me, both in the previous 4, and now 5, Autocal will have the value on the Zero line, then do a couple of clicks more, and now is either somewhat close, or further away from the Zero line!
Appendum: Due to the idiosyncrasies of electronics, I find it Best to do AutoCal immediately after doing the Manual 2 and 10 Point, plus CMS Calibrations.
Doing AutoCal the next day, does not give as good results.
Have opted for the Advanced Calibration Workflow, versus Enthusiast, due to Enthusiast missing the 2 Point Calibration Menu Feature.
So my Calibration consists of doing the Manual 2 and 10 Point Calibrations, followed by the following Autocal routine:
2 Point, 2 X Autocal 10 Point (*), 2 Point, 2 X Autocal 10 Point, 2 X CMS. Back to 2 Point, 2 X 10 Point, 2 X CMS - Finished.
* - Due to AutoCal liking to insert Spikes periodically, will sometimes end up re-doing X3s, and odd time 4Xs. (During AutoCal, Meter will keep
clicking away, with Red, Green and Blue, near or at the 0 Point.(Absolute for 10 Point) When it's finished, before moving to the next IRE Point
in it's agenda, it will give either a R, G or B spike that's no longer at the 0 Point. Most often it's the Blue, less often Red and Green.
Sometimes as far away from 0 as being +/- 10! (Why is this?)) Re-reading that particular IRE Point afterwards, the same spike is still there!
Problems involving 100IRE not being consistant, both in Manual and in AutoCal, constantly causes the rest of the IREs to have to be re-calibrated.
(Again idiosyncrasies of the TV's Electronics? And Yes, I do realize after each 10 Point Calibration, the 100IRE values will change, just not
that much, worse with AutoCal versus Manual!)
Notes: Depending on how you run your system, 2 Point with 10 Point Calibrated, or 10 Point with 2 Point calibrated, if using the latter, one
must always remember to switch back to the TV's Menu of 10 Point during the switch back and forth from the 2 to 10 Point Calibrations. (Elsewise
you end up with different results - try it sometime - do a 10 Point reading with TV Menu on 2 Point, then the Menu on 10 Point -
a different chart will result.)
My LG 55LHX has a Darbee in line from my iScan Duo to my LG 55LHX. Found a more precise CMS AutoCal calibration with the Darbee sitting at
my Normal setting. Before Calibration found the Max I could go was HD50 to 60%. Afterwards - 80%, but for long time viewing - now at 70%.
Did my last Calibration set to 70%. Also found after calibrating without the Darbee (Completely Removed), inserting the Darbee after, then
taking a complete reading, my results showed a somewhat elevated Red level. So I now leave the Darbee in during the whole calibration proceedure
