I got a triple DP1.4 KVM for 2 terminals and I’m trying to figure out how to move between the 2 channels by using the keyboard. Keyboard is plugged into a USB HUB that’s then plugged into the KVM. I also tried plugging keyboard in a HID port directly, but it wasn’t working (keyboard is an ATmega32 chipset).
Tried Scroll Lock x2 + numbers but to no avail. Any ideas?
What is your exact keyboard brand/model? If your keyboard is using a VIA/QMK firmware, you have to disable the n-key rollover function by its dip switch (maybe check under or on the side) or flashing a firmware with a disabled n-key rollover.
