This allows the display to sync its refresh rate with the GPU's output, reducing stuttering in gaming and saving power during low-motion tasks. Technical Evolution to 1.4a The 1.4 specification laid the groundwork for , released in 2015. This update leveraged the VESA DisplayPort 1.3 standard to support even higher resolutions, such as
: Supports HBR3 (High Bit Rate 3) at 8.1 Gbps per lane . With a 4-lane configuration, it provides a total bandwidth of 32.4 Gbps, enabling support for 4K, 5K, and 8K displays . edp 1.4 specification pdf
The Embedded DisplayPort (EDP) 1.4 specification is a widely adopted standard for display interfaces in embedded systems, including laptops, tablets, smartphones, and other mobile devices. As a high-bandwidth, low-power interface, EDP 1.4 enables the transmission of high-resolution video signals between a source device (e.g., a laptop) and a display panel. This allows the display to sync its refresh
