Thought of leaning more about manual calibration given my success with Calman Autocal on my LG projector. I have a 2018 Panasonic OLED TV. The 2019 OLEDs have a built in pattern generator, like the LG projector, but the 2018s do not. They do however support Autocal if you have an ip driven external pattern generator. However, pattern generators costs thousands of $ and I haven’t seen any place here that rents them. There is a cool solution by using the free MobileForge software from Portrait Displays (Calman), which runs on an iPhone or Android. But how to get it to my TV? Answer is Apple Play. So I have Meter->PC<>iPhone via Wifi<>Apple TV 3rd gen->TV
It works so far. Am measuring display with Calman now. Not sure how accurate it will be, but if I download the Calman for Panasonic, I should be able to run Autocal.
