AMD’s efforts to open source drivers are sometimes used as future indicators.News Through photons See the latest Linux kernel patch Add preliminary support for the DisplayPort 2.0 protocol in the AMD GPU driver.
The DisplayPort 2.0 specification was announced a long time ago. In 2019, the DisplayPort Working Group released the final specification and made it available to display manufacturers. However, it is reported that due to the COVID-19 pandemic, these displays that support DisplayPort 2.0 have been delayed, so we currently do not have them on the market.
The DisplayPort 2.0 protocol allows transmission of ultra-high bit rates (UHBR) of 10, 13.5, and 20 Gbps per channel over passive copper wires. This means that the data transmission rate is higher than the previous DisplayPort 1.4 protocol, and the bandwidth is larger, so as to achieve better image output.
The patch lined up for the Linux kernel merger brings updates to the AMD GPU display driver and adds support for UHBR 10, as UHBR 13.5 and 20 are not currently supported. Since UHBR is compatible with VESA’s DisplayPort 8K (DP8K) certification, the new protocol will allow us to run the monitor at 60 Hz 8K resolution and high dynamic range (HDR), and 4K monitors with a refresh rate over 144 Hz can also run high. Dynamic Range.You can learn more about the agreement and its limitations here.
Since the patch is waiting to be added to the AMD GPU driver, we know it is applicable to the next generation of graphics cards. Since the current generation of RDNA2 GPUs lack support for DP 2.0, the upcoming RDNA3 series will provide the latest protocol support. The first batch of DP 2.0 monitors and displays are expected to be available in the next few months.
