Q: Why KVM-A3/KVM-A4/KVM-A8 does not show the video only display No Signals?

A:

1. Please check the hardware connection. Double-check that the video capture device is connected correctly and tightly.
2. Make sure you use the original HDMI port. If your desktop only has a VGA display port, there may be no video signal when you use VGA to HDMI adapter, and there is no way to solve this; However, you can try to lower the resolution and restart the PC to test, but the probability of success is very low.
3. Change the HDMI cable to test.
4. Test the X630 separately to check if there is HDMI output.
5. Some laptops do not output any signal until you switch the output (usually via the FN + and an F5 key on the keyboard).
6. Your computer maybe enter sleep mode, please exit sleep mode.

Q. Does KVM-A8 support passive heatsink such as (P165-A or P165-B etc) instead of fan?

A: You can use the P165 aluminium heatsink or the H402 pure copper heatsink, but must remove the X630-A8 fan and fan connector.

①If use P165-A(thickness 7mm), you can use M2.5*5mm spacer instead of M2.5*12mm spacer to fix it;

②if use P165-B(thickness 11mm), you can directly use M2.5*6mm screws to fix it;

③if use H402(thickness 4mm), you can use M2.5*8mm spacer instead of M2.5*12mm spacer.

You can also use other suitable spacers + screws to fix the heatsink.
