We have the same issue. At first, we thought it was one of the dock/monitors/cables but after replacing them all, the issue persisted. The 5330 model has a lot of display connectivity issues in our organization. Some simply don't connect to displays until they've been restarted twice (even when connecting to a Dell UltraSharp hub monitor). Hoping that Dell fixes it soon as we now own 185 of these devices and many get used with multiple displays.

I should add we've tried swapping cables, HDMI instead of DP, different monitors etc. 

Hi @tmbaCCmn and @TPSAdmin 

I agree, a lot of people have this issue with latitude 5x30 and external display through type-c docking station (but also with a simple hdmi adapter!).

......just one of many threads!

Have you found some solution? 

It is clear that DELL could fix, have you received any support?

Hi @tmbaCCmn again.

possible solution try this, hopefully it is matter of graphics driver.

We tried the graphics driver and it didn't help.

Problems with the WD15 and Dell U2422HE screen with built in docking station.

today one of my colleagues switched me to an WD19 which worked. IMO it happened out of the blue, no dell software updates. stopped working since yesterday.



Also boot problems for the last 2 weeks on latitude 5330, had to switch of camera, fingerprint and internal audio to get it booting again. however that behavior is not consistent. it also stopped booting with those settings disabled. got it working again by selecting last working bios configuration.

will yet try to reset the entire bios.

kind of frusty!

We have the same issues. Latitude 5320's and WDS19S docks are fine. The same docking station with 5330+ has the blanking display issues, tried multiple different WDS19S docks, same issue. Older WDS15 docks are fine.

Dell support have been no help, saying to try different cables. Already tried that, even had laptop motherboard replaced, same issues. 

Drivers firmware all up to date. 

I am having a similar issue.  Monitors stopped working for no apparent reason while using the docking station. 2 monitors connected via display port to a Dell Latitude through Dock WD19. Reboots, driver updates do not fix.  Worked for two days then stopped.

We have multiple customers with 5530 and WD19S reporting this problem. Changing docks, updating has not resolved this up till now. Glad to see we are not the only ones.

Same issue here, Latitude 5530 and 7430's with Dell WD19s docks and two 1080p monitors, have applied firmware updates, replaced cables and docks and the same problem persists.  For one user, I replaced their monitors and that seems to have helped but it's obviously not cost effective or practical to do that for everyone. 

Another problem with this dock and monitors is that the resolution appears to randomly change to something much lower resulting in heavily distorted images, unreadable text and extremely delayed performance.  I don't recall what I did to fix it, but powercycling the monitor and toggling sources doesn't help.  If I remember correctly, I think we had to powercycle the dock.

Oddly, I'm using the same dock on a Dell Vostro 5620 with two monitors (one 2K and one 4K) and do not have any issues.
