HDCP On or Off for BenQ XL2411Z DVI -> Display Port?

3 on 20-06-2021

Should I order the HDCP On or Off variant?  Also what Displayport version should I get (1.2 vs 1.4 etc) for this monitor?  Montior is the BenQ XL2411Z

Hi Bzeeb,

You’ll need the CAC-1010 – HDCP ON.

DisplayPort version on the adapter is 1.2a. GPU with DisplayPort 1.2a or higher will support the adapter.

Even though the adapter is DisplayPort 1.2, it only supports max HBR link rate so it might work with a DisplayPort 1.1 GPU?

Since the adapter uses HBR link rate, it means it cannot do 2560×1600 60Hz from a USB-C dock (because USB-C docks only have two lanes of DisplayPort input) unless the USB-C dock includes an MST Hub (MST can convert two lanes of HBR2 or HBR3 to 4 lanes of HBR).

USB-C docks that don’t support USB 3.x (in other words, they support USB 2.0 only) can have four lanes of DisplayPort input. Such docks don’t need an MST Hub to support max resolution of 2560×1600 60Hz (or 4K 30Hz) from an HBR only adapter like the CAC-1010.
