What customers say
Customer feedback on this DisplayPort MST Hub is notably divided, centering primarily on ease of use and performance consistency. Users who successfully configure the splitter highly value its capability to expand productivity with triple monitor setups from one port, praising the robust build quality typical of SIIG hardware. However, many users experience significant frustration. Achieving simultaneous high resolutions across all three outputs proves difficult due to inherent DisplayPort 1.4 bandwidth limits. This often forces users to reduce refresh rates or resolutions, leading to disappointment. The device demands technical patience and specific cable quality, making it a powerful niche tool rather than a simple plug and play solution for the average consumer.
