Hello, I’ve had the 4K Dual Monitor KVM Switch, 2-Port HDMI with Hotkey Switching, Supports High Refresh Rates like 144Hz, 165Hz & 240Hz since April, and unfortunately over the last few months it seems to have developed a problem.
The keyboard will randomly stop working, where I need to push the “Change input” button. About 30% of the time, when it comes back to the PC, the right (of 2) monitor is just digital noise.
I can’t see a pattern, often I have a single PC on, it works fine for hours then suddenly, no keyboard Mouse still works. I push the Change Input button, the other PC is Off, push again and keyboard works. However, 30% of the time when I do that, the right monitor is digital noise. It eventually seems to re-sync but this can take 10-15 minutes during which the PC is unusable.
I’ve had the above happen when the 2nd PC is On, or in Sleep mode, it doesn’t seem to make a difference.
Thanks for reaching us and we are so sorry for the issues.
