CalMAN Home Samsung Works With JU7500
First post here, but I think I've got something useful.
I have a 55JU7500 UHD TV from 2015 and, according to the site, CalMAN Home Samsung only works with 2015 and 2016 SUHD TVs (8000 and 9000 series). I can confirm that this is not the case, as I have successfully calibrated my 55JU7500 using CalMAN Home Samsung and a USB to 2.5mm cable. That second part is also important because CalMAN says you need a USB to Serial adapter and a Serial to 2.5mm cable plus some CalMAN drivers. This is not accurate in my experience, as with the USB cable plugged into the EX Link port on my TV, CalMAN recognized the TV as a 2015 SUHD TV and controlled it just fine.
For patterns, I used MobileForge and AirPlay from a 2018 12.9 iPad Pro 512 to an Apple TV 4K 64 connected to input 1 on the Samsung 55JU7500 TV I/O box.
Here's the setup using a Microsoft Surface Pro 2 i7, 16GB RAM, 1TB HDD, and performance base (dGPU):
CalMAN Home Samsung
Green-utech PL2303TA 6ft Usb Rs232 Serial to 3.5mm Stereo Aj Cable (Amazon)
The TV and colorimeter were both plugged directly into the standard USB A ports on the laptop (no hub).
I've attached my before and after from the final screen of CalMAN Home Samsung's workflow. I used the snipping tool after everything was disconnected by pulling up the saved cal file, so please ignore the "yellow" items in the upper-right. All three are green when hooked up per specifications above. I took a pic and video on my iPhone to share with friends if anyone needs to see it working.
Also, for reference: the "before" data in the CalMAN screenshot represents the cal settings from rtings for the JU7500.
Really hope this helps someone, let me know if there are any questions I can answer.
