When it changes to 24hz and u see it flicker for couple of sec , the color management gets stuck sometimes, to fix it just enter the color managment tab and change to any other setting and back to ur prefered one.I wish that was the problem. 60hz is only for the playstation menu. When I played the 24hz bluray, it went "no input," black screen, then a splash of interference or distortion over the screen, and then the picture showed up, 1080p/24hz. But every time the projector changed inputs, you could see it flicker and start to rev up like an engine, like it had to gain its speed from the start again and you could see it slowly speeding up until you couldn't notice it anymore.
For the blu ray, it did did say 24hz vertical refresh but 26.7 or something horizontal refresh. Maybe 26.9hz horizontal refresh, I have to go back and look. Just like for the playstation menu, it says 60hz vertical and 67hz horizontal or something. It was the same like that, but for 24hz vertical and 26.x horizontal.
This will not happen when u calibrate with LCC software but it get stuck with the stock presets.
Also do not keep the HDMI range to auto, auto always chose 16-235 , so if u are using full on ur source u have to manually chose 0-255.
Concerning CA do u see it from ur seating distance ? All rgb leds has small CA when very close specially to the edges but shouldnt be visible from seating distance.
As for motion it shouldnt have any issue , when its 24hz, does it say on the info that its 24hz and 48hz ? Or just 24hz , maybe the source isnt outputing real 24hz, when i use it on my pc the motion is just perfect.
