Yeah, I’m going to just run the DP cables loose and see if that fixes the problem. If it does, I’ll try to cable manage them in a separate area under the desk.
I’m using overkill gauge power cables… not sure if that makes a difference either way…
I’m not sure it would. It definitely helps, but the most important factor is current and insulation, not AWG.
Yeah, I just wonder to what extent the insulation is stepped up between gauges…
I couldn’t say.

I made an interesting discovery with this KVM today. My monitor, an LG 38UC99, frameskips at 75 Hz if no AMD GPU is connected. When I tried connecting my Surface Book (which has Nvidia/Intel graphics) to the monitor, it would frameskip at 75 Hz. However, I noticed that if I switch to the SB through the KVM after powering on my main desktop which has an AMD GPU, then the SB runs fine at 75 Hz.
If I reboot the SB, the “fix” doesn’t persist, goes back to frameskipping at 75 Hz. But toggling back and forth from my main desktop to the SB, gets it working again.
Just found this interesting. I wasn’t expecting the 75 Hz to work, but nice that it does.
Any updates on this? It seems like the pre-order might not happen or that there are delays, but is there an expected availability?
I think Wendell’s prioritizing the bug fixing at the moment. There are some show-stopping problems with it on AMD and/or Linux.
Probably up for order (no preorder should be necessary, next batch already ordered) around May 28 or so +/-
Still investigating some issues sgtawesomeauce and others ordered. going to see if its a signal conditioning issue though, sent some stuff to people to test.
also one weird bug with a usb headset… trying to reproduce that

would you like a tester? I’ve always been direct-attaching my headset, but I can try running it through the KVM.
++, thank you for the update.
FWIW update on my end, I took everything apart and put it back together again. Seems to be working fine now, so DP cable interference was likely to blame. Kind of nuts that it took a complete shutdown to restore the display when I was having the issue before.
I do still get occasional black screen but it comes back within a couple seconds. Here is the dmesg immediately afterwards.

I think it’s just a DRM AMDGPU bug. I know there are numerous fixes incoming on Linux kernel (currently on 4.15.17-65.current).
the nouveau driver is especially a turd in not retrying like you’re supposed to. just fwiw

AMD in my case but yes, it definitely required a power cycle to renegotiate the connection.
Is there a full list of hotkeys somewhere? Other than what’s in the manual. I’d like to switch to scroll lock as it’s interfering with games. I would like a full list for any other things I might be interested in
Is there any way to get notified when the new batch is available? There is going to be a new run for the Dual monitor variant, right?

Yes and yes. I will reply on this thread so subscrive/notify on it
We are about 2-3 weeks away +/-
I absolutely NEED one of the dual-monitor versions. Can anyone confirm if this supports HDCP 2.2 pass thru?

You can confirm your issue is mostly sorted? Down to the “built in” MST hub in those monitors (meant for daisy chaining) and turning that off fixed the issues prettymuch?
