Use a DP 1.4 switch: https://www.amazon.com/Angusplay-DisplayPort-Switch-Bidirectional-Splitter/dp/B089SLDDZZ/ref=sr_1_3?dchild=1&keywords=thunderbolt+switch&qid=1619119846&sr=8-3 https://www.amazon.com/Angusplay-DisplayPort-Switch-Bidirect...
I tried ConnectPro's DP 1.4 KVM and the display blacked out constantly in MacOS. Friends who purchased the same KVM ran into the same issue with displays that push DP spec to the limit like 3440x1440@144.
The switch I shared works just fine. From time to time (once every 1-2 months maybe) the display blacks out for a second but a computer restart does the trick, or reconnecting cables. Also make sure to get HBR3 displayport certified cables.
- anyfoo 5y agoJust to confirm, this does work with LG 5k monitors? The resolution there is 5120x2880, which is significantly more (the vertical resolution alone is doubled, and then some for the horizontal), but I don't know the refresh rate, so the bandwidth could still be similar maybe. EDIT: I'm also wondering, the only switch I know to be working uses two display port cables to the monitor (which I'd have to adapt to one Thunderbolt 3 instead), while your device only uses one. That doesn't bode well...
- ggayan 5y agoNot sure: irb(main):003:0> 5120288060 > 34401440144 => true
- ianhowson 5y agoIt won't work with the LG Ultrafine 5k, which requires a Thunderbolt connection to run at full resolution, and behind-the-scenes is a tiled pair of DP1.2 displays. It ought to work with a DisplayPort 1.4 5k, though there aren't many of those.
- anyfoo 5y agoThanks. So as far as I can tell, that ridiculously expensive switch is still the only option (if even, I wasn't able to fully confirm), and nowhere near worth the cost vs. just physically swapping the cable between computers.
