Why the device does not show the video only display <b><span class="tb_red">No Signals</span></b>?</div><div class="mw-collapsible-content">A: * Please check the hardware connection. Double-check that the video capture device is connected correctly and tightly.* 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.* Change the HDMI cable to test.* Test the X630 separately to check if there is HDMI output.* Some laptops do not output any signal until you switch the output (usually via the FN + and an F5 key on the keyboard).* Your computer maybe enter sleep mode, please exit sleep mode</div></div> <div class="toccolours mw-collapsible mw-collapsed"><div style="font-weight:bold;line-height:1.6;">Q3.
