As the development of the next-generation mainline kernel progresses steadily, the upcoming Linux Kernel 7.4 has achieved significant upgrades in its display layer and graphics driver architecture. The open-source driver patch merge tree and the latest code submissions reveal that the new kernel natively introduces support for AMD FreeSync Variable Refresh Rate (VRR) on HDMI interfaces, as well as Auto Low Latency Mode (ALLM), a core feature of the HDMI 2.1 specification. This comprehensively addresses the functional gaps of the Linux platform on modern large-screen TVs and high-end gaming monitors.
