Please change the keyboard mode of your keyboard from NKRO to 6KRO to solve this problem. NKRO function would let the USB package become longer than the standard package, ATEN KVMs will be unable to recognize it. Please refer to the support website of the keyboard which mentions "what is key rollover?". https://www.hyperxgaming.com/en/support/technical/products?model=hx-kb1 |
