Bandwidth and Resolution
To understand whether DisplayPort 1.2 can handle 165Hz at 1440p, we need to consider the bandwidth requirements for such a setup. The resolution of 1440p, also known as QHD (Quad High Definition), has a pixel count of 2560 x 1440. Running this resolution at 165Hz requires a significant amount of bandwidth. The calculation of the required bandwidth involves the resolution, refresh rate, and color depth. Assuming a common color depth of 24 bits per pixel, the bandwidth needed for 1440p at 165Hz can be calculated.
Bandwidth Calculation
The formula to calculate the bandwidth requirement is: Bandwidth = (Resolution x Refresh Rate x Color Depth) / 8. Plugging in the numbers for 1440p at 165Hz with 24-bit color depth, we get: Bandwidth = (2560 x 1440 x 165 x 24) / 8. This calculation yields a bandwidth requirement of approximately 12.54 Gbps. Given that DisplayPort 1.2 has a maximum bandwidth of 17.28 Gbps, it seems feasible that it could support 1440p at 165Hz, as the required bandwidth is below the maximum capacity of the interface.
