Maximilian’s desk is filled with multiple computers and laboratory devices. Each time he powers on, he expects seamless switching of input devices—without any machine interrupting his workflow. The HDK402-M24 has become the core of his daily setup: powerful in capability, yet it briefly experiences keyboard and mouse lag during startup, along with repeated USB disconnections.
The challenge became greater. He frequently needs to type characters with diacritics, while the original right Alt key served both as an input modifier and a switching hotkey—making errors almost unavoidable during intensive use.
After analyzing the issue, the TESmart technical support team provided a clear and practical solution: connect the keyboard and mouse to different USB ports on the mainboard, update the firmware, and reassign the switching hotkey to the left Alt key. The process was straightforward, and Maximilian quickly completed the upgrade.
Afterward, he shared his feedback:
“Left Alt now works great. This makes it so much better!”
Keyboard and mouse switching became smooth, text input felt natural, and experimental data processing grew more efficient. More importantly, he realized that the HDK402-M24 is not only powerful hardware—it is also backed by attentive, professional support.
This case highlights a key truth: for a high-end, feature-rich KVM product, continuous, expert, and actionable technical support is itself a core part of the product’s value.
The HDK402-M24 delivers not only strong hardware capabilities, but also meaningful software optimization and user-focused support—ensuring a smooth and reliable experience in demanding, multi-device professional environments.
