    Hello, I bought the PiKVM-A4 kit. All works well except the OLED screen. I tested it on an arduino and it works. I have enabled the screen in the terminal and it is active in the PiKCM settings. How to check if the X630-A4 board has a problem? Thanks

    Hello, This is normal and not a problem with X630-A4. Because the screen will not work if the mirror is used with PI ZERO.  PIKVM OS has not solved this problem.If the system fixes it, the screen will be available. Hope to get your understanding. Thanks~

    Hi, official audio support is added. Is this working on Geekworm A3? Can you add instructions for how to connect I2S to X630? https://docs.pikvm.org/audio/

    @Snuupy Snup Hi，

    The I2S Audio in（10pin SH1.0 connector） of X630-A3 is for I2S HDMI audio support. But you need a I2S cable.

    I noticed on a new install, I was having several errors in the system log every 5 seconds related to kvmd-watchdog.  I used the v3 Hat version of PiKVM on the A8 PCIe product.  It appears to be a difference in the hardware used by the official PiKVM hat and the GeekWork A8 hardware.

    I eventually found in a github post that I needed to disable the kvmd-watchdog using the following command:

    [root@pikvm ~]# systemctl disable --now kvmd-watchdog

    All is well now, but not sure what features I disabled when I turned off this service.  If you have any ideas, please let me know.  For GeekWorm staff, I am able to test out any solutions you may have.

    Thanks,

    Tom

    I have a working kit.

    However I only get video using an HDMI-HDMI lead.

    When I use an HDMI-VGA lead there is "No signal".  This same lead works fine to a monitor.

    I am trying others - as Amazon has a good free return system!

    Can you point me to a lead that works with the PiKVM.

    This issue is surprising, as I maintain dozens of SuperMicros and they all have VGA sockets.  In fact I haven't encountered *one* computer with an HDMI socket built in.

    Hello,

    I have PiKVM-A3 Kit and it is working very well. I want use some GPIO pin for extensions, but I'm not sure which are free and not used by your board. Can you please supply a schematic or a list of the used pins of the Pi IO header.

    Thank you.
