the good news if you do find one that works, you know you can safely flash it onto your card, then it works everywhere
Yep, just switched back to the 1070 for host, reconfiguring everything now. Since our conversation the other day, I’ve moved back to fedora as well, so hopefully no more passthrough issues will rear their head.

@Wendell, update:
I’m encountering the one-core-pinned initialization issue on Fedora with this system as well. I’m going to log my debugging process in the other thread.
In regards to the actual KVM though, I’ve found that nouveau on Fedora 27 (4.15.9) has issues recognizing both monitors on the 1070 even with the good cables. Once I switched to nvidia 390, the problems reduced considerably.
I’ve also found that using the good cables (provided by you) between KVM and monitor has improved the success rate of input switching. I’m still not entirely confident this is entirely a KVM or cable issue though.
Do you have an ETA or plans for a cable bundle item on the store? I’d love you forever since it’s not very prudent for me to order a 500-unit bulk order in a situation when I only need 6.
Nouveau does seem to have super crappy error handling

Sooo, is there a chance you guys are making another batch of kvms?
yes, it will be 4-6 weeks before this batch is ready. Debating on whether or not to take pre-orders. Anyone up for a pre-order?
There are a couple of issues users have reported that made me worried I might need to prep a newer firmware but so far (knock on wood) the only issues are not fixable from my end w/firmware (mac pro 2013 handshake failure, and graceful handling of displayport noise).
I am thinking I may also sell a cheap displayport repeater/conditioner/spliter that will likely resolve almost all issues with weak and garbled DP signals, and buggy graphics cards like the D300s in 2013 Mac Pros and some USBc adapters).
I will want to add some notes about the edge cases we’ve encountered so far to help people w/their purchase. The next largest annoyance is the OS can re-arrange windows and icons when switching inputs. There are some ways to mitigate that but that’s not really a KVM thing per se.
Also old USB logitech wireless recievers are buggy AF and need to die.

I’ve found that Gnome sometimes encounters this, but Windows does any time the monitors go to sleep, A solution might be to never sleep the monitors. I’ll play around with that idea. (I’ve got a dual-head solution working for my bare metal windows system, powered by Fury)
Windows has an option to use edid from file on Nvidia and that also works great.
Oh, that’s awesome! Come on, AMD. Get in the game!
generic solution? https://docs.microsoft.com/en-us/windows-hardware/drivers/display/overriding-monitor-edids

Im down for pre ordering. I just got moved from field programming to office programming. Not in a hurry just put-in together a set up. 
This would be fantastic. I think there’s definitely demand out there for a problem-free 4k displayport cable.
I would love to pre-order one of these for the office.
I’d be up for pre-orders.
Cheers.
I would also like to pre-order. Thanks!
Any update on the firmware? This damn 580 is still causing problems, apparently.

This is noise on the DP line. This is going to sound weird, but can you put the metal case of the KVM in contact with the metal case of your computer? wondering if it is a grounding issue maybe. using the l1 cables for the 580?

Using all L1 cables. They arrived last week. Thanks babe!
I’ve actually got the kvm resting on top of my case (Meshify C), I can drill in a grounding strap/cable if you think it’s worth going all the way.
which 580 is it? using an asus 580 it seems flawless. Is this on bare metal or vm?
Bare metal and MSI 580. (linux)
