Both external monitors work fine, when connected to either of the Spectre USB-C ports, but only one at a time. I have plenty of adapters to choose from when that magical Thunderbolt 3 port decides to work (without turning my fan into a drone motor).I am trying to connect two external monitors to my Spectre via the two USB-C ports. So, I'll fix my immediate problem and wait for Dell to fix theirs. I see that even noted Googler, Benson Leung, who had taken it upon himself to 3rd party validate USB-C cables, was burned (literally) when a shoddy cable fried his beautiful Chromebook Pixel and several pieces of kit connected to it. Perhaps that is what I deserve for being ahead of all the accessory set for the USB-C/Thunderbolt 3 port.
In fact, I kind of blame Intel - it's their chipset and tech. I have some confidence that Dell will get this fixed. In fact, except for which ports are being used, I'm set up and stable the way I hoped. No problems whatsoever and no crazy fan speeds. I've always had great success with my Plugable video cards and, while waiting for UPS, I'm presently using an older Plugable USB 3.0 to DVI unit connected to an older monitor as display #3.
I ordered a Plugable USB 3.0 to 4K HDMI that does 2560x1440 at 60 hz (DisplayLink drivers). I've temporarily given up on the Thunderbolt 3 port. Really, really strong evidence of a Thunderbolt 3 problem, right? I'd be curious to know if those using the new Thunderbolt docking station have noticed the other ports going flaky during the display events. One fact on this front is that when I had the DA200 connected via HDMI to my 3rd screen AND the ethernet port in use, the ethernet port also went flaky when the display events occurred. Disappointed in that, as I liked the idea of it and gig ethernet port running simultaneously. The DA200 didn't reach to the native resolution of my monitors, which is 2560x1440. I noticed that the max resolution on the Dell DA200 "mini-dock" HDMI port is somewhere below that of the dedicated USB-C to HDMI cable.I was hopeful when I saw the new Thunderbolt 3 driver.

I've since let that driver automatically update to the latest direct from nVidia. I rolled back on the nVidia driver to the latest Dell issued version.For now, I've rolled back to the latest Dell issued Intel video driver. I updated the Intel video driver to the latest direct from Intel by deleting the Dell driver.

I'd appreciate it if you came back and posted what version of Windows you're using. I've experienced the same problem with three different Dell 4K monitors now. By the way, it's definitely not your monitor. But because my machine is 4K and my external monitor is 4K, I never thought to use the onboard laptop's HDMI 1.4 port, which does not support 4K at 60Hz. I contacted support and had a very long dialogue with them that lasted over a month. They are really good about updating their drivers, firmware etc. I suspect Dell will get this ironed out in time.

You say the blinking off and on problem doesn't happen with HDMI, that would indicate that the Thunderbolt 3/USB-C port, or more likely its controller software (which Dell updated only a few days ago), is at fault.
Whether I connect the DisplayPort cable to a Thunderbolt 3 adapter or the Dell Thunderbolt Dock the results are the same. I have the TB15 Dell Thunderbolt Dock too. It's a pity Dell doesn't offer the option in BIOS to select what the laptop does when the lid is closed. But if the same problem exists in Windows 8.x, then that theory seems unlikely. The laptop may be erroneously and ineffectually sending the signal to the display to sleep. Are you running Windows 10? I've speculated that the half completed Control Panel => Settings overhaul isn't fully blocking the "closing the lid" power-management functionality, even with the "Do Nothing" setting in vogue. I have the same problem with a DisplayPort connection using the and an external display.
