tone map HDR using pixel shadersIam using Madvr tone mapping with this projector, however i noticed that in the information the vpr tells me that i am using the color space BT.709 and not BT.2020, it seems that the vpr goes into BT.2020 only when it receives a signal in HDR, is there any way I can make the projector detect the BT.2020 color space when I use madvr tone mapping?
HDR is converted to SDR through combined tone mapping, gamut mapping and transfer function conversion. The display receives SDR content. output video in HDR format: The display receives HDR content, but the HDR source is tone mapped/downconverted to the target specs.
It's a check box on the HDR settings under devices
Also, configure the calibration of the device to BT.2020 for HDR signals:
4K UHD Display:
- primaries / gamut: BT.709 (Auto/Normal) / BT.2020 (Wide/Extended/Native)
- transfer function / gamma: pure power curve 2.20
