How to reduce the latency of USB Capture HDMI 4K Plus

If you are experiencing frame drops and lag with the USB Capture HDMI 4K Plus, please follow these steps to troubleshoot: Check the capture software settingsEnsure that the recommended setting in the capture software is 1920x1080p 60fps RGB24/YUY2. If the settings exceed this recommendation, frame dropping may occur. For example, if the capture software is set to 4K 60, the USB 3.0 bandwidth limitation may prevent the capture from reaching the set frame rate, resulting in frame dropping and stuttering.  You may check the output format on USB Capture Utility. Connect USB 3.0 port with the USB 3.0 cableConnect the USB Capture HDMI 4K Plus using the original USB 3.0 cable. Make sure to connect it to the USB 3.0 port on your computer, which is usually colored blue, blue-green, or red. Avoid connecting to black ports, as they are typically USB 2.0 ports. For desktop computers, it is recommended to connect to the USB 3.0 ports on the rear panel, as front panel ports with long wires may lead to insufficient power supply. Check the USB port speedUse USB Capture Utility to verify the actual speed of the current USB port. Ensure that it is operating at USB 3.0 speed. If it is running at USB 2.0 speed, switch to a USB 3.0 port or reconnect the cable. Check whether there are other devices occupying USB bandwidth  Disconnect any other USB devices that may be causing the drop in speed. If the above methods do not solve your problem, please email to sales@magewell.com.
