Hello!
The problem is serious, since it is not clear what is the matter. I say in advance: I bought all things in the secondary market, there is no guarantee.
So I have a DELL LATITUDE E7450 laptop, I bought a DELL E-PORT PLUS docking station for it (by the way, officially my laptop is not supported as I understand it, but I thought that the only difference is in the port location and since everything works or worked, I don’t have any complaints caused).
Then I bought the first BENQ B2320HDB (et-0032t) monitor, in the beginning everything was fine, even a few films were watched. Then, slowly, the problem began to manifest itself: the monitor began to turn off periodically and then turned on, since I used the laptop as the main screen, at first I ignored these shutdowns. Now it has come to the point that the monitor turns off and turns on itself every few seconds, it is impossible to use.
Here is video from yesterday on YouTube:
Yesterday I bought two monitors to use two of them, forgetting about the old monitor and the laptop screen. But the problem started to torment me, according to which BENQ still shuts down, since I got another DVI cable with the purchase of monitors and was able to test the benq monitor that still worked on VGA, in general the problem did not go away.
But! Yesterday, strange shutdowns of one of the new monitors called iiyama ProLite B2483HS began. It was several times, after that I worked for several hours normally.
And today, right after turning it on (at that moment both the iiyama and another DELL monitor were connected via the DVI to the dock), the yiyama started to turn off and on continuously for a few second :shock::cry:, I disconnected everything from this dock immediately, I have now connected only iiyama via HDMI to the laptop and am writing this text, while everything seems to be ok ...
Until today, I thought that the first monitor was slipped to me idle, and now it turns out that the docking station was already nailed to me? It (benq) now turns on and off by itself, even without connecting a video cable, first the benq screensaver lights up and shows that there is no connection, and then everything with the LED goes out and a little later on repeats again.
Thank you in advance!
Mike

P.S. maybe what software is missing?

Do both monitors work nomrally when connected directly to the laptop rather than the dock?

Hello trents,
the problem is hat all 3 monitors have different combinations of ports. My laptop has HDMI and mini-DP, and from 3 monitors only 1 (iiyama which I use now) has HDMI and no one has mini-DP.

There are adapters available to convert our laptop's ports' signals and physical shape to the ports present on your monitors. You can get these on ebay too. You yourself said in your first post that the docking station you have was not supposed to be compatible with your laptop. If you go this route, make sure you get an "active" adapter and not just a physical port converter. Active adapters change the signal too.

Thank you. Of cource I know about adapters, but I would like to use dock station and if the problem is with it, I go to buy other, maybe newer model which must be 100% compatible.
Actually I am working with dock station and both new monitores and both were shut down themselves for 1 time but in different time.
Now I have 6 connections to the dock station - 2 monitors, mouse and keyboard, power and speaker and it is not all, maybe I will also connect portable DVD-ROM and HHD or even iPhone. And then I will take laptop with me somewhere and every time connect all things again is not nice. Just want to know where is the problem..?

I didn't Google all the specs of th eparts involved, so I'll ask: Is the native resolution of the monitors involved more demanding than the laptop's? My thought being maybe it's straining the GPU in the laptop, which already has a cooling problem by virtue of it being a laptop. Which also brings up the laptop cooling overall, ie; Clogged cooling inlet, sitting on a bed, etc..

No, it is not a peoblem. Laptop himself has full hd and monitores are also. Laptop (intel graphics hd 5500) can also 4k. And, I do not play games, only office stuff

Ok, problem still exist, the new monitor iiyama has switched off several times today, the same troubles like BENQ at the beginning. Finally I found one article about this problem at Dell website, but Recommended Troubleshooting Steps does not help at all and ask dell support I cant also since guarantee has expired. They say the problem exist when I connect 2 monitors, but I have had the same problem with one BENQ, until this monitor has died and now need to repare.
