想問下依家有無出到>90% BT.2020色域的Panel?
對應返Channel 4K D 規格 (10bit/bt.2020/入4:2:0出4:4:4)

DCI-P3就有人試~

CX700 DCI P3接近90%:

CX800得~80% (可能test unit問題)

反而Sony有:

The KD55X9305C to reach 91% of DCI-P3 standard anyway with [Colour space] set – somewhat ironically – to “BT.2020“. [Colour space] “DCI” came in slightly smaller at 89% DCI-P3.

但係點解佢要Test DCI-P3色域呢 民用都唔用呢個標準
小弟未係網上找到過DCI-P3色域既影片
試過播Channel 4K D片, 係madVR到set將BT.2020 remap做 DCI-P3,
U2410 set去 Standard 模式去用盡最大色域

U2410 色域:
