This user had a very fixed work routine.
Every day, he switched back and forth between dual-screen mode and mixed-screen mode:
-
In dual-screen mode, both PCs maintain extended displays.
-
When switching to mixed-screen mode, he wanted all open windows to automatically appear on the currently active display, rather than manually dragging them.
However, in practice, problems quickly arose.
After switching to mixed mode, some windows did not appear on the visible monitor—they remained on a “screen that no longer exists.” Each switch required extra time to recover the missing windows.
He described his workflow in the support ticket and asked:
"In dual-screen mode, both PCs are set to extended display, but in mixed mode, the display behavior switches to duplicate. That is my preferred way to work. Is there a way I can switch ON or OFF the EDID on the unit I am having? Rather than returning. Thanks!"
The issue isn’t the windows—it’s the “retained screen.” When reproducing the scenario, we noticed a key point: in mixed-screen mode, the device’s EDID emulation is enabled by default. This means that even if only one display is physically connected, the system still “sees” a second display. So when switching from dual-screen to mixed-screen, the operating system does not automatically redistribute the windows, because it considers the second screen to still exist. Windows not moving automatically is actually completely consistent with system logic.
A controllable switch is more important than fixed behavior. After identifying the cause, the core need became clear: the user wanted control over EDID behavior in mixed-screen mode. The team added a new feature in the firmware: in mixed-screen mode, users can manually turn EDID emulation on or off using a shortcut. When EDID is turned off, the system correctly recognizes that only one display remains, and open windows are automatically moved to the active screen.
Back to the user’s original workflow. After upgrading the firmware, the user confirmed the issue was resolved:
"Thanks for the firmware! Now it works exactly like what I expected." Switching modes no longer disrupts workflow, and windows no longer “disappear.”
One adjustment, more freedom. The problem itself was simple, but it occurred in a high-frequency operation. By making EDID behavior in mixed-screen mode controllable, the device no longer forces users to adapt to fixed logic—it gives them more flexible ways to work. For users, the change is felt in every seamless switch; for the product, it is an enhancement that makes display behavior align more closely with real-world needs.
