Precision 5530 and TB16 black screen flashing/flicker
I've searched the forums across the internet and this is a common problem that has not been fixed!
When the notebook is waking up from standby and/or connected and reconnected to the dock the screen flickers/flashes black on all connected screens.
When will Dell provide a working solution as all suggested workarounds do not mitigate this problem?
After a reboot the problem will start appearing again.
EDIT: Video from my later posts
- I have this same setup on about 15 machines in the office. Only one of them seems to be doing this. I haven't seen any new video driver updates but I'm wondering if it could be related to this new fix in the latest BIOS revision "The package also fixes the issue with the graphics performance where it becomes limited when the temperature of the system is low." Not that it is cold in the office, but worth a shot.

Updated to the latest bios 1.7.0 and it is still happening.
Same problem here...
Dell 5530 and TB16 dock-using 2 Dell S2240T monitors, one connected to the TB16 hdmi, the other connected to the TB16 full size display port through a plugable DP > hdmi 2.0 adapter. (these monitors don't have Display Port connections)
Even though the 5530 has a 4k display, I have it set to 1080p so that the interface on certain programs isn't microscopic. I use 100% scaling on the external monitors and 125% on the 5530. When it happens, all monitors (including laptop screen) will go black for about a second, then come back.
There seems to be some association with sleep. If I reboot, it will be fine for a long time, then if the computer is locked or goes to sleep and is woken back up, it tends to start flashing again. When it is occurring, the monitors flash off for about a second every 10-30 seconds. Also, I can pull the cable for the TB16 from the laptop and the built-in display will continue exhibiting the problem, except the flash is only a fraction of a second.
Just found this info which sheds more light on the problem:

Thanks, i've created that reddit thread. :)
What i've experienced now is, that with the 25. driver it's somehow possible to fix it without reboot.
What i've done is, set no standby/ monitor off when docked. Also i've changed the lock screen timeout to a couple of hours when docked.
So know if the flicker starts, i simply disconnect the type c cable. Wait until everything is settled and then reconnect. It's still an inconvenience but managable.
I'm getting similar issue but only when I use "stand alone laptop".
After I switched off all "power saving" settings in Intel Graphics control panel I get rid off my issue from: https://www.dell.com/community/Precision-Mobile-Workstations/Dell-Precision-5530-ociasionaly-hanging-freezing/td-p/6233832 but get this flicker / refresh problem.
So you can try set all settings from power to off in Intel Graphics Control Panelsolid_0_snake

For me there is no difference if power saving settings are disabled or enabled.
I will get the flicker everytime the notebook wakes up from sleep. Docked or undocked.

Hi Alan, Our support team suggested the following:
I actually used a stopwatch and did 45 seconds.
I've been flicker free for 3 days now.
