    Hi there

    Since I bought my new setup (2018 MBP 15 w/ Radeon 560X, CalDigit TS3+, 2x LG 4k monitors) last year I've been seeing some weird behaviour, and I'm wondering if anybody else sees the same thing.

    When my laptop is connected to my 2 screens via the dock, when the machine turns off the external screens, the screens notify me of this twice. As in, they show me a ’no signal’ message, and then switch off. They instantly switch back on to a black screen, and show me the ’no signal’ message again.

    This doesn’t happen when the screens are connected directly to the Mac. I see ’no signal’ once.

    Before anybody asks what the actual problem is, I've had endless trouble with the entire setup. In particular there have been a lot of issues with the screens glitching out in various ways. Currently at 9 months (!!!) of non-stop contact with Apple Support. So I'm fishing for clues. And praying for closure.

    How are the screens connected to the Dock? (as in, what cables into what ports)?

    What specific model #s are the monitors?

    The screens are these: LG 27UD68P-B https://www.lg.com/dk/skaerme/lg-27UD68P

    And they're connected via DisplayPort. The TS3+ only has one DP output, and I'm using the DP cable that came with the monitor for that one. The other monitor is connected to the TB3 port on the dock, using a USB-C -> DisplayPort cable.

    We've tried a bunch of different cables. Apple even sent me a pair of the ridiculously priced Moshi cables they have in their store. Didn't make a difference.

    Have you contacted CalDigit about this?

    Have you tried it with either, only one display connected, and/or; different displays connected (to the dock)?

    I haven't tried different displays; I don't have access to more unfortunately.

    But I've tried pretty much everything over the past 9 months; one screen at a time still does the double-off.

    The thing is this effect is an annoyance at worst. I'm just interested in hearing if it's abnormal. Because if it is, the dock may be a little off. And at this point 'a little off' is something that needs to be isolated and removed.

    This is by far the most expensive setup I've ever built for myself, and to this point it's *by far* the worst experience. And I've been doing this for a while. I ran multi-screen Hackintosh setups in the past that gave me way less trouble.

    I missed this bit. But yes.

    Originally when I got the machine (shortly after release) everything with this machine was catastrophic, but most of that turned out to be on Apple's side.

    I've just contacted them again about this specific thing. Awaiting a reply from a technician.
