Issue: No video on the TV or monitor
\n1. Check power to the receiver (RX)
\nMake sure the RX is plugged into a USB-A port.
\nThe USB-A port must provide at least 2.3 W.
\nIf video still does not show, try a different USB-A port or a USB power adapter.
\n2. Check the HDMI connection
\nMake sure the HDMI cable is firmly plugged into the RX.
\nMake sure the other end is firmly plugged into the TV or monitor.
\nOn the TV or monitor, select the HDMI input where the RX is connected (HDMI 1, HDMI 2, etc.).
\n3. Check if your device supports video over USB-C
\nThe USB-C port on your laptop, tablet, or phone must support video (DisplayPort Alt Mode).
\nIf the USB-C port does not support video, the ConnectAir cannot show an image.
\n4. Try re-pairing the TX and RX
\nOn the RX (receiver): press and hold the reset button for 2 seconds.
\nOn the TX (transmitter): press and hold the pairing button for 5 seconds.
\n\n
\n
\n
Issue: Transmitter will not pair or connect
\n1. Reset the receiver (RX)
\nPress and hold the reset button on the RX for 10 seconds.
\nThis returns the RX to factory settings.
\n2. Reset the transmitter (TX)
\nPress and hold the pairing button on the TX for 5 seconds.
\n3. Try a different USB-C port
\nUnplug the TX from your device.
\nPlug it into a different USB-C port on the same device, if one is available.
\n\n
Issue: Video is lagging, delayed, or looks blocky / pixelated
\n1. Shorten the distance and clear the path
\nKeep the TX and RX in the same room.
\nMove large metal objects, thick walls, or cabinets out of the way if possible.
\n2. Change the wireless band
\nOn the RX, press the reset button once (a quick tap).
\nThis switches between 2.4 GHz and 5 GHz.
\nWait a few seconds and check the video again
\nThe Belkin ConnectAir (AVC024) is designed to wirelessly cast high-definition video from your device to a TV or monitor with a maximum resolution of 1080p at 60Hz.
\n\n
However, you may be experiencing a black screen, an HDCP error, or a "protected content" message.
\n\n
This occurs when a source device (like a phone or laptop) attempts to send a 4K signal. Because the AVC024 is not built to process 4K resolution or the specific security keys associated with 4K streams, the display fails to show the image.
\nTo resolve this, we need to align your device’s output with the adapter’s capabilities. By manually adjusting your resolution settings to 1080p, we can bypass the 4K conflict and allow the video to pass through to your TV.
\nPlease try the options below to synchronize your resolution.
\nThis ensures that your phone or laptop sends a 1080p signal for everything displayed, preventing the adapter from being overwhelmed by a 4K signal.
\nSome streaming apps (like Netflix or YouTube) operate independently of your main device settings and may try to force a 4K stream automatically. We need to tell the specific app to send a compatible video feed.
\nStill seeing a black screen?
\nIf the issue persists, ensure the video has actually switched resolutions by restarting the streaming app, or try playing a different non-4K video to confirm the connection is working.
\nHow to Connect Your Laptop to a TV or Monitor with ConnectAir
\nYou will use:
\nRX = Receiver (goes on the TV/monitor)
\nTX = Transmitter (goes on the laptop)
\n\n
Step 1: Set up the Receiver (RX) on the TV or Monitor
\nPlug in HDMI
\nPlug one end of the HDMI cable into an HDMI port on your TV or monitor.
\nPlug in USB power
\nPlug the RX’s USB cable into a USB-A port on the TV or into a USB power adapter.
\nThe USB port must give enough power, so if the TV USB is weak, use a wall adapter.
\nSelect the HDMI input
\nTurn on the TV or monitor.
\nUse the remote or buttons to pick the HDMI input where the RX is connected (for example: HDMI 1, HDMI 2).
\nYou should now see the ConnectAir screen or a pairing screen on the TV/monitor.
\n\n
Step 2: Plug the Transmitter (TX) into Your Laptop
\nPlug the TX into a USB-C port on your laptop.
\nIf your laptop has more than one USB-C port, use the one with a small display/monitor icon if available. That port usually supports video.
\n\n
Step 3: Put the Receiver (RX) in Pairing Mode
\nOn the RX, find the reset button.
\nPress and hold the reset button for 2 seconds.
\nRelease the button. The RX is now in pairing mode.
\n\n
Step 4: Put the Transmitter (TX) in Pairing Mode
\nWith the TX still plugged into your laptop, find the pairing button on the TX.
\nPress and hold the pairing button for 5 seconds.
\nThe LED on the TX will start flashing. This means it is trying to pair.
\nWait up to 30 seconds.
If pairing works, your laptop screen should appear on the TV or monitor.

How to Connect Your Mobile Phone to a TV or Monitor with ConnectAir
\nYou will use:
\nRX = Receiver (on the TV or monitor)
\nTX = Transmitter (plugs into your phone)
\n\n
IMPORTANT: Check if your phone supports video output
\nBefore you start, your phone must support video over USB-C, sometimes called DisplayPort Alt Mode.
\nExamples:
\nMany Samsung Galaxy phones with Samsung DeX support video out.
\nSome other Android flagships also support video out.
\nIf your phone does not support video output over USB-C, ConnectAir will not show anything on the TV.
\nIf you are not sure, check your phone’s specs for:
\n“USB-C video output”
\n“DisplayPort Alt Mode”
\n“Samsung DeX” or similar desktop mode
\n\n
Step 1: Set up the Receiver (RX) on the TV or monitor
\nPlug in HDMI
\nPlug one end of the HDMI cable into an HDMI port on your TV or monitor.
\nPlug in USB power
\nPlug the RX’s USB cable into a USB-A port on the TV or into a USB power adapter.
\nThe USB port must give enough power, so if the TV USB is weak, use a wall adapter.
\nSelect the HDMI input
\nTurn on the TV or monitor.
\nUse the remote or buttons to pick the HDMI input where the RX is connected (for example: HDMI 1, HDMI 2).
\nYou should now see the ConnectAir screen or a pairing screen on the TV/monitor.
\nStep 2: Plug the Transmitter (TX) into your phone
\nTake the TX unit. Plug it into the USB-C port on your phone.
\nKeep the TX plugged in during pairing and use.
\n\n
Step 3: Put the Receiver (RX) in pairing mode
\nFind the reset button on the RX.
\nPress and hold the reset button for 2 seconds.
\nRelease the button.
\nThe RX is now in pairing mode.
\n\n
Step 4: Put the Transmitter (TX) in pairing mode
\nWith the TX plugged into your phone, find the pairing button on the TX.
\nPress and hold the pairing button for 5 seconds.
\nThe LED on the TX starts flashing. This means it is trying to connect to the RX.
\nWait up to 30 seconds.
\nIf pairing works, your phone screen appears on the TV or monitor.
If your phone has a desktop mode such as Samsung DeX, you may see that interface instead.
\n
If it still does not connect
\nReset both units
\nRX: Press and hold the reset button for 10 seconds (factory reset).
\nTX: Press and hold the pairing button for 5 seconds until the LED flashes.
\nTry again
\nRepeat Step 3 and Step 4 with the TX still plugged into your phone.
\nIf nothing shows on the TV even after pairing:
\nYour phone probably does not support video out over USB-C.
