I just bought a Level 1 DP 1.4 KVM and I set it up yesterday. I got everything working except on my Mac Pro 2019 the screen goes black and resets on and off every minute or so. The monitor acts as though it is resetting and displays the “DisplayPort” overlay in the corner.
The computer works when plugging directly into the monitor.
I read on the product page that some thunderbolt 3 Macs have issues with the KVM where their signal strength isn’t enough and that it’s fixed by a DP repeater. Are the above symptoms indicative of that issue?
I figured I’d ask before buying something that wouldn’t solve my problem.
Yeah, I figure that’s a chance, but if it doesn’t work I can probably pick up a L1 repeater and just use it in 1.2 mode and give up HDR until there’s a better solution.
I’m using a TB to Display Port cable, Club-3D brand. I just hooked a different brand cable up and it hasn’t reset yet, so maybe that cable was the issue.
The cable that seems to work is “Maxonar” brand and was cheaper than the Club-3D one.
I’m excited to get this working. Having my Gaming PC and Mac on the same monitor frees up a lot of space on my desk. I also haven’t had any issues with my icons rearranging or anything, which I was worried about.
