From a YouTube post by LTT.com, sounds like they finally achieved the goals shown in the 3rd column here:I was just wondering about this. RTINGS CX values for SDR are 414 and 176 peak. IF these are the appropriate values to compare, then it's about 33% and 5% brighter respectively. Also, IF people buy the very rough rule of thumb that the human eye needs to see ~30-50% brighter to be 'noticeable' (qualitative) since we have a logarithmic response, then we might say this improvement might be juuuust noticeable for the glint off some chrome or a brighter moon, etc. You won't notice anything for full screen. I'd hazard a guess that you wouldn't notice the difference unless you had a CX and C1 side by side. That's my 2 minutes of thinking about, which is always dangerous. Any other thoughts?
