<div style="font-weight:bold;line-height:1.0; color:red;">Q1Q: Why PiKVM[[KVM-A3]]/[[KVM-A4]]/[[KVM-A8 ]]/[[X680]] does not show the video only display No Signals?
</div>
<div class="mw-collapsible-content">
A:
* First refer to the [https://docs.pikvm.org/faq/#video-problems Video problems] to troubleshoot
* 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 <b>VGA to HDMI adapter</b>, 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.(run the <code>ls /dev/video0</code> command, if you see anything such as '''/dev/video0''' other than file not found, then it’s available )
* 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.
* '''Feedback from users:''' If you're using something like '''NGINX Proxy Manager''', you must have '''Websockets Support enabled''' for it to work correctly – screenshots below:
:[[File:Pikvm-websocket-enable.png]]
* '''Feedback from users:''' Multiple Network IPs. if you'll have similar thing in the future: janus is using stun servers for determining public ip address, if the network has several public IP addresses and route traffic through multiple of those, janus via stun will detect the change of the network and restart the stream each time
:Solution: either lock traffic from pikvm through one gateway (one public IP address) or configure some sort of session persistence (sticky connection)
* Run the command <code>systemctl status kvmd-tc358743</code> to check whether the video service is working properly.

Q: Why OLED is not display?
</div>
<div class="mw-collapsible-content">
A: Please follow the steps below to check
1. Please confirm that the OS is correct according to your Raspberry Pi version:
Due to downloading the wrong firmware, the OLED cannot be displayed. We ALSO made such mistakes during testing
*For Raspberry Pi 4 : https://pikvm.org/download/
[[File:Pi4-V3-HAT.png|800px]]
*For Raspberry Pi Zero 2 W : https://docs.pikvm.org/flashing_os/
[[File:PiKVM V2 Platform.png|800px]]
2. Please check if the order of OLED screen pins is correct, please email to support@geekworm.com if it's a wrong pin order;
[[File:OLED-IMG-4373-1.jpg|800px]]
The run the following command to check the I2C address
sudo i2cdetect -y 1
<pre>
0 1 2 3 4 5 6 7 8 9 a b c d e f
00: -- -- -- -- -- -- -- --
10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
30: -- -- -- -- -- -- -- -- -- -- -- -- 3c -- -- --
40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
70: -- -- -- -- -- -- -- --
</pre>
3c is a hexadecimal number, it is the I2C address of OLED, if you can’t find this value, please shut down and reconnect shield and OLED, then run this command again, If you still can't find the OLED's I2C address, the OLED screen may be damaged.
'''PS''': Since the i2cdetect tool is not installed by default in pikvm os, you need to install it first. You can install it through the following command
<pre>
pikvm-update
rw
pacman -S i2c-tools -y
</pre>
4. Then run the following command to enable OLED display:
rw
systemctl enable --now kvmd-oled
ro

Q: How to connect to wifi?
</div>
<div class="mw-collapsible-content">
A: Refer to [https://docs.pikvm.org/first_steps/ | Optional setting up Wi-Fi]
If you want to connect KVM to a Wi-Fi network, you need to tell the device ESSID and password before first boot. To do this, mount the first partition of the memory card (FAT32) and edit or make the pikvm.txt file there. Do not remove line FIRSTBOOT=1 or FIRST_BOOT-1 for first time booting, just add your wifi settings like this:
<pre>
FIRSTBOOT=1
WIFI_ESSID='mynet'
WIFI_PASSWD='your password'
</pre>
There is a possibility that, in countries that support CH13, the device will not connect. You will need to configure your router to disable channels 12-14 or disable Auto scan mode so it will connect.
Save, unmount and follow the next step.
