2. How easy would it be for a novice to use Calman for Home?
Just wanted to try and answer your second question. I'm a novice that just performed my first ever TV calibration using Calman Home for Samsung on a 55JU7500. I used a Spyder5 colorimeter, a Green-utech PL2303TA 6ft Usb Rs232 Serial to 3.5mm Stereo Aj Cable (from Amazon - for direct TV control) and Mobile Forge on a 2018 iPad Pro 12.9 (using AirPlay to my Apple TV connected to the TV to display the patterns).
I'd say on a scale of 1-10, 10 being the easiest, it's a 6/10 or 7/10 for a novice. The walkthrough for the software is a little off and confusing at points, though. Needs some corrections/clarification IMO. Here are my walkthrough notes:
1. The walkthrough says calibration "is impossible" without a $32 serial adapter plus another cable. That's actually incorrect, as the USB to 3.5mm adapter I mentioned above works fine for $13 and it's plug-and-play on Win10. No extra drivers needed.
2. Starting in Step 3, the walkthrough starts referring to clicking "read series," "read continuous," etc. These buttons aren't obviously labeled. You have to hover over the small square buttons above the "back" and "next" buttons in the lower-right to figure out which is which. This lack of obvious buttons is worse with making direct control display adjustments from the software, but basically hover over any blue horizontal bar and arrows will pop up allowing you to adjust TV settings from the PC (brightness, contrast, backlight, etc).
3. I personally missed the note that says "click the Full DDC Reset button" on my first cal attempt, and from the posts here in this thread, it sounds like I'm not the only one.
4. Step 5 (White Balance/Grayscale 2pt) is out of order in the walkthrough, which was mildly disorienting.
5. Step 6 is more confusing than it needs to be, as it asks you to adjust the brightness to 15% above your target without telling you what your target should be. After research, looks like 100 is the standard peak luminance target, so 15% above that would be 115. I think the software should suggest targets for folks who don't know or understand this.
6. Step 9 will be the hardest part for novices like me, as the walkthrough is confusing and unclear:
6a. It says to "Adjust the display's Brightness and Contrast controls to set dynamic range" but it only explains how to adjust contrast. The instructions for adjusting brightness are literally, "Click the Brightness
button to display the brightness pattern then adjust brightness manually." I have no idea what that means, but it's the grey box on a black screen so I assumed I make the brightness as low as possible without the center box disappearing entirely. I'm still not 100% sure if that's right.
6b. For the datapoint levels drop-down, I think you have to choose "Clipping" if you're using MobileForge. It defaults to "Clipping with Peak White," but no matter what I did per the instructions, the luminance graph plateaued at 1. If what I did was correct, the CalMAN should automatically default to "Clipping" in this step since the program already knows I'm using MobileForge (made by the same company).
6c. The last part of this step is possibly the most confusing. It says "Select the 100/235 pattern, click the Read Continuous button, and adjust the display’s peak white to the desired luminance from Step 6.
" The big issue with these instructions is that there is nothing that says "100/235 pattern" nor is there an adjustment for "Peak White." What I believe they want you to do is click on "100" in the lower left to display that pattern on the screen, then click "read continuous," then adjust the Luminance slider (which I think is the CalMAN name for the "Backlight" adjustment on the Samsung OSD) to hit the target from Step 6 (which in my case was 115).
In my first cal attempt, without clicking "Full DDC Reset," my average dE (which I think is the deviation from the sRGB definitions of particular colors/shades) went from around 5 to under 2. I was using the recommended cal settings from rtings prior to my cal.
Hope this helps!
- Removed confusion over LCD types, I realized I should have chosen LED not CCFL normal or expanded range.
- Replaced "workflow" with "walkthrough" for clarity.
I tried re-accomplishing the cal last night choosing LED as the TV type and making sure to click "DDC Reset" prior to calibration. My numbers came out WAY worse and I wish there was a way to revert... My initial autocal (clicking CCFL normal range and not clicking DDC Reset) gave me an avg color dE of 1.6/max 4.2 and avg gray dE of 0.7/max 1.7. Choosing LED and clicking DDC Reset gave me color avgs of 2.3/max 6.4 and gray avgs around 2 with a max above 5 (10% and 100% were way off). Ran it several times with similarly poor results, the only thing I changed was lowering my luminance target from 100nits to 50nits per the luminance suggestions in CalMAN's help file.
Also, no matter what you set your dE targets to, the auto adjustment software seems to give up after a certain number of adjustment attempts.
