David, My dad has this exact same set and same problem. did you ever figure it out because I’m having the exact same problem my 30/80 isn’t to far off but I know it can be better. whenever i chage any of the 6pt Gamma settings I notice no difference. Looked through all 32 pages and didn’t see anything that look like saving/writing.
Also is the CMS on this system any good? I attempted and took green saturation to -30 and still couldn’t get it to balance.
Thanks.
