No picture on the room display
- Check the HDMI cable from the Surface Hub 3 85" to the display, and that the display is on the right input.
- Restart the Surface Hub 3 85" from its settings, or by removing power for 30 seconds.
- Check the camera isn't covered by a privacy shutter.
- Update the firmware.
Picture is blurry, dark or badly framed
- Clean the lens with a dry microfiber cloth.
- Make sure auto-framing or speaker tracking is turned on in Microsoft's app or the device settings.
- Light faces from the front; avoid a bright window behind people.
- Check nothing blocks the board's camera at the top of the screen.
No sound or people can't hear you
- Check the device isn't muted (look for a red mute light).
- Check the volume on the device.
- Move laptops and their fans away from the microphones.
Echo or feedback
- Make sure only one microphone and one speaker are active in the room: mute laptops that also joined the meeting.
- Don't run the room's audio through both the device and the TV speakers at the same time.
- Hard, bare rooms reflect sound. Rugs, curtains or acoustic panels reduce echo a lot.
- Update firmware: echo cancellation improvements often come in updates.
Keeps disconnecting or drops out
- Use wired Ethernet rather than Wi-Fi, and check the switch port for errors.
- Update firmware.
Won't turn on or status light is red/blinking
- Check the power adapter is the original one and firmly connected, and try another outlet.
- Unplug for 30 seconds and power it back on.
- Check the status light meaning in the user guide; a blinking light during startup or updates is often normal.
- If it never finishes starting, contact the manufacturer's support for a recovery.
When to contact Microsoft
