我下了2480的产品说明书和一些说明PDF,都是官方提供的,看来确实是可行的,而且HP也多次提到这方面的应用,摘抄不同位置的几个关键的段落
With most video sources (which typically provide video information at the standard 8 bits/color or 24
bits/pixel), and across all of the LP2480zx’s various inputs, the increased accuracy of the LP2480zx
LCD module is used to provide more accurate color within the selected standard color space. However,
30-bit sources may also be directly supported using the DisplayPort 1.1 and HDMI 1.3 inputs only. This
will be of greatest benefit when the LP2480zx is used in the wider-gamut modes (such as Full, Adobe
RGB, DCI).
For professional video applications, it is strongly recommended that one of the digital video inputs
(HDMI, DVI, or DisplayPort) be used. All digital inputs support 8-bits per pixel inputs and the HDMI
and DisplayPort additionally support 10-bits per color.
HP recommends the following product for this purpose:
Gefen, Inc. HD-SDI to HDMI Scaler Box (SKU: EXT-HDSDI-2-HDMIS)
大意就是对于不同的视频源,选择匹配的色域空间可以增加色彩的准确性,而当使用DP 1.1或者HDMI1.3时候,支持的源视频的采样精度甚至可能高达30BIT,这让2480在自身的广色域模式下如虎添翼。
如果是专业视频应用强烈建议使用数字接口,HDMi和DP支持10BIT采样色彩
它还推荐了2480 用于SDI转换HDMI用来监视的设备就是
GEFEN公司的HD-SDI to HDMI Scaler Box
这个玩意的售价我查了下,大概1000美金
