I’m writing this blog entry using my spare Windows 11 PC connected via JETKVM – so I’m sitting at my normal fast PC (all hardwired) with the JETKVM at full screen hence I’m seeing my secondary PC full screen and accessing it to write this log.
Slight key lag, actually a little annoying – but usable.
I’ve set video quality to highest and if I sit here and open up a Chrome browser window – select Youtube I can watch the new Avatar – Fire and Ash trailer full screen and apparently with no stuttering.
I have to say very good but for one thing – up to now, no matter what I do I’m getting no sound through from the target computer.
MAC address hidden in the above image to protect the innocent! i.e. me.
Erm, but I just captured a photo into the clipboard on my main PC screen (2 screen system) and now I’m back on the second screen blogging – PASTE from the main PC does not seem to be doing anything.
Slight diversion – I’ve switched to my GL-iNet Comet KVM to continue this – no copy-paste from the main machine to the target machine either…. and.. ah but the clipboard, there’s a way in the newly updated Comet interface to paste text across… to the target but not the other way as far as I can tell…
Back to the JetKVM…. No audio – that’s still a work in progress….
Update November 05, 2025 (original was October 3, 2025): okay so, JetKVM sent me a new version of the device because the sound didn’t work on the original, and I’ve just received it and I’m going to tell you all about it in a minute. Before I do that, I thought I’d plug the original JetKVM back in. It ran, the video ran great, and I know that there was an update in the app, which of course there would be. For the new one, they told me that you really want to run the update.
How the actors keep a serious look on their face when covered in black marks like that, and everybody watching them is well beyond me. They are really clever these people! The role of the actor has certainly changed a lot in recent years.
Anyway, I tried the update on the original, and it’s screen comes back up, but my main PC, as you’ll see soon, is still seeing update in progress 10 minutes later, so a little way to go. But the old board still works after a reboot.. Above is a not-hi-res image from the YouTube Avatar video I regularly use for testing. The actual quality from YouTube is great.
So, the original model picture is perfect, remote access is perfect. There are a ton of controls. This is a really good KVM, but no sound. And I didn’t see any cross-machine clipboard copy working either.
Enough of the original – I’m going to unplug it and plug in the new unit that just arrived, upgrade it and see what happens:
So I plugged in the little unit and on it’s display, it’s own address popped up – I put that in the browser on my PC and everything seemed to work. I then upgraded the firmware. Same misleading “rebooting” message long after updates were complete. So after ensuring I’d given the device time to upgrade and reboot, this time I just refreshed my browser – sure enough – all’s well – it wasn’t the JetKVM after all – my Youtube video is still running.
Checking in Windows on the target PC I checked audio output – thinking I’d have to redirect that to the HDMI on the target – but no, options are just to send to the normal output of the machine. That’s disappointing. So no audio, still a slight lag and no cross-machine clipboard copy and paste – I checked the many setup options – nope.
Don;t get me wrong – this is a great KVM depending on your use case, well built, tiny, solid and easy to use but no sound – and that missing cross-machine copy and paste is a pain. I’ll forward this to JetKVM and if I’m missing something I’ll update the blog accordingly.
Update April 6, 2026
As promised – updates – well, since receiving some other KVM products and moving house, my JETKVM has been sitting in a moving box. Meanwhile I’ve mounted my Home Assistant box on a shelf in the living room, the box being attached to a monitor and keyboard (it’s command line so no need for a mouse). As you can imagine not the most living-room-adapted product (and only rarely used to check the status of HAOS at the command line in case it is stuck in recovery mode etc., (rubbish power here right now) then this morning it hit on me to get the JetKVM out of it’s packing box and attach it to the HA mini-PC.
As before, a slight keyboard lag and I thought to myself (I’ve not updated the firmware on this since last year) – so, sitting at my PC I went off for the update – 2.5.4 – sure enough, no more keyboard lag. JetKVM is connected via Ethernet – I could connect by WiFi – but the whole lot is going in a cupboard next to my router so why introduce a level of uncertainty when it isn’t needed.
What a great use for the KVM – a shame no-one will ever see the neat little OLED display on the front.
