Starting Point of the Story
A German user, Mat Thias, contacted us through the ticket system with a pre-sales inquiry. He clearly described his dual-laptop setup: ThinkPad L14 Gen6, Dell Latitude 5520, two Samsung monitors, three sets of USB wireless peripherals, and found our TESmart CKS202-P23 dual-monitor USB-C KVM. He wanted to confirm whether it could reliably support his workflow.
His questions were very focused:
• Can both USB-C laptops connect stably through the KVM?
• Will the notes in the product description affect compatibility?
• Can both laptops operate in clamshell mode?
• Can multiple USB receivers be recognized correctly by the KVM?
These questions reflect common concerns among dual-USB-C users.
What the Customer Was Truly Worried About
From his repeated follow-up questions, we could see that what worried him was not “whether it works,” but:
• Is USB-C power delivery sufficient, and could it damage the battery?
• Will clamshell mode cause the system to go to sleep?
• When switching to another laptop, will he miss incoming Webex calls on the work laptop?
• Does the KVM pose any data-security risk, especially when one laptop uses corporate VPN and the other is personal?
All these concerns point to one underlying emotion:
“I need to make sure this system won’t break, won’t disconnect, won’t misoperate, and won’t compromise data security.”
Our Assessment and Actions
For every round of questions, instead of answering with only specifications, we broke things down step by step:
• Confirmed both laptops support USB-C + DP Alt Mode, enabling video and USB switching through a single cable
• Explained that 60W PD may show a “low-power charging” message but does not affect functionality, and requested a photo of the original power adapter for precise evaluation
• Provided steps for clamshell-mode configuration to avoid black-screen issues caused by system sleep
• Explained how to use USB 3.0 focus switching and audio focus to avoid missing meeting-software notifications from the work laptop
• Clarified that the TESmart KVM works at the physical layer, does not interact with network/data/VPN traffic, and does not create cross-device data risks
We not only answered “whether it works,” but also “why it will not cause problems.”
How This Case Drove Improvements
Through this full support process, we discovered several key gaps from the user’s perspective:
• Low-power charging alerts from USB-C PD may make users mistakenly think it’s unsafe
• Whether incoming calls on the work laptop can still be heard is a core need for dual-host users
• Users are highly sensitive about data isolation when a corporate-VPN laptop and personal laptop coexist
• The use of multiple USB peripherals requires more intuitive guidance
Therefore, we decided to:
• Add a “60W PD behavior explanation” to the product page
• Publish a new blog on “How to avoid missing video-meeting calls”
• Add a clear “KVM works at physical layer, does not access any data or network” security statement
• Provide a more detailed “USB focus-switching strategy” diagram (already used in the support ticket)
These improvements were all inspired by Mat Thias’ representative questions.
Conclusion: This Is Not Just Q&A — It’s Making Hidden Needs Visible
Mat Thias’ series of questions helped us realize that for dual USB-C users, the most important things are not bandwidth specs, but:
• Security
• Stability
• Predictable behavior in real use scenarios
• Clear explanations that prevent misunderstanding
He prompted us to bring user-centric concerns forward in our documentation.
This made our product documentation more complete and more human-centered.
This is what we call “co-creation”:
“Not because he intended to buy, but because his scenario made our understanding clearer.”
