Random black screen during 1-2 seconds

HP Recommended
HP EliteDesk 800 G3
Microsoft Windows 10 (64-bit)

Hi,

 

Since few days, i am facing a problem on all the 800G3 EliteDesk PC i got.

Randomly, i got a black screen, for a during of 1 or 2 second. It can happen 5 or 6 times per days.

 

I already tried to use HP SDM to upgrade every firmware/bios/drivers, it still happen.

I've changed on a single computer the DisplayPort cable to a HDMI cable, and it seems to correct the bug.

But currently, i am not able to change all the cable on all the computer, because i don't have enough connectors for HDMI.

 

Would you have an idea where the problem come from  ? How to solve it ?

 

Thanks,

 

Alexandre

I am experiencing this also on all of the following hardware, :

 

HP ProDesk 400 G3 DM Intel i5-6500T

HP EliteDesk 800 G2 Desktop-Mini-PC (65 W)

 

Sometimes, the problem appears 10 times per hour which makes it difficult for relaxed working.

On some desktops, we have connected 2 screens.

I have the same issue, several 800 G3s are doing this after upgrading to Windows 10 version 1803 from Windows 7.

I have had similar issues on a HP Z440 Workstation and did some searching and relized that my problem was the DisplayPort cable. Many people have the same problems and i bought a DisplayPort cable from UltraAV, the "UltraAV® DisplayPort to DisplayPort Version 1.2 Cable, 2M".

 

Since i bought that cable all problems disappeared. 🙂

 

I did try a no-name DisplayPort cable before buying the UltraAV cable, but it did not work. It´s worth trying on one (1) computer. Google it and you will find where to buy it. 🙂

I managed to resolve the issue by updating display/graphics drivers with the HP Assistant, downloaded from the hp website from here: https://www8.hp.com/ch/de/campaigns/hpsupportassistant/hpsupport.html

 

good luck
