This is not a personal tech issue, but more of an inquiry into the capabilities of the Thunderbolt 3 controllers.
Let us say one were to use a Gigabyte GA-Z170X-Gaming G1 (rev. 1.0) motherboard. This board is now a certified Thunderbolt 3 motherboard. It also features a MegaChips MDCP2800 LSPCON to convert one of the DP 1.2 signals from the processor into an HDMI 2.0a w/ HDCP 2.2 connection. So assuming we are using Windows 10 Pro x64 and this motherboard, could a display manufacturer create a Thunderbolt 3 display that receives 8 HBR2 (5.4Gbps) lanes (Thunderbolt 3 mode via the USB Type-C connector) from the Thunderbolt 3 controller with HDCP 2.2 protection? Could a display manufacturer create a DisplayPort 1.2 display that receives 4 HBR2 (5.4Gbps) lanes (DP1.2 native mode via the USB Type-C connector) from the Thunderbolt 3 controller with HDCP 2.2 protection? Could one of these theoretical displays receive HDCP 2.2 protected content simultaneously with a connected HDMI 2.0 display (via the MegaChips MDCP2800 LSPCON powered HDMI port) receiving HDCP 2.2 content?
Since I know of no currently available Thunderbolt 3 or DisplayPort 1.2 displays with HDCP 2.2 support, this is more of an inquiry into the Thunderbolt 3 controller's capability, as in, can it inject HDCP 2.2 protection for Thunderbolt 3 mode and/or DP1.2 native mode connections, and can it do this side-by-side an LSPCON that converts DP1.2 to HDMI 2.0a w/ HDCP 2.2?
