KVM Model:
DP 1.4 dual monitor, dual PC
USB Interface (5-gigabit or 10-gigbit):
USB 5-Gigabit
Problem:
I hope this post finds you well.
I’m officially throwing in the towel and writing this post at my wits end. Currently, I have reduced down connections to a single machine and a single monitor (though both USB cables are plugged in). Signal path (at least, where I am now) consists of 2x 2m FIBRR DP cables, both having been flipped in their direction to rule out the various permutations (these particular ones don’t seem to indicate directionality with branding/labeling - though unlikely old stock as all 6 I procured have this “issue”). Machine one’s USB is connected to my desktop, and machine two’s is connected to the dock’s USB (specifically, Kensington SD5600T that has been observed to work with a “lesser KVM”), with machine two serving as my sanity test with a single DP going from the dock to the KVM,and the KVM to the monitor (3440x1440@175Hz, no osd without a signal, OLED & HDR as it matters but no signal).
Currently, both machine lights indicate connection (green), but no HID keyboard I plug in, nor input on the select switch, seems to invoke any response. I’ve been unable to get it to select an output as of late (red(?)).
Other Notes:
Tried:
-Seperate DC power input to KVM
-Directionality on both input and output cables flipped (reverse the polarity!)
-Copper DP cables (UGreen 2m)
-Another pair of FIBRR DP (2.1, specifically, these are what I procured, feel free to mock my folly if applicable: FIBBR Certified DisplayPort 2.1 Cable https://a.co/d/cTSKUa9), also flipped directionally
Is there anything obvious I may have missed, or otherwise misunderstood? Thank you in advance for your time!
