One of my 3 displays does not come back properly from "sleep"


#1

Just asking if anyone else had had this and if so how they fixed it. One of my Prolite 1080p displays is acting a bit weird.
So I have my displays turning off after 10 minutes of inactivity. Actual sleep mode is disabled.
When I wake these thing back up one of the displays is showing the image completely distorted.
If I power that display off and back on everything is perfect again.
The other Prolite and the middle screen is fine.
Both of the prolites are connected via hdmi.

swapped cables/ports to be sure it’s specific to that monitor/rule them out?

Have you tried degaussing it?


#3

I have swapped the ports around on the GPU side, made no difference.
I might have to get another hdmi cable any recommendations? I believe that the HDMI that is there now a maplin branded one so that could be the issue. The other cable is the only one that is long enough to reach the other side of the desk so I don’t really want to move that.

How do I degauss an LCD?


#4

press the button harder than on a CRT. and blow on it a bit first, that usually helps.

I’m assuming it’s something that’s started recently and it was previously fine? Any warranty on the monitor?

Recent thing yes. I did notice that some of the options on the setup of the screen were not available. Came back after doing a “factory reset”. I think it is the cable as the problem is only happening when the power saver comes on. If i power the screen of and on again it is fine. So I think the wakeup thing is not coming in to the screen properly. Oh and it is only recently that I started using HDMI on this.
These are old screens no warranty left.

I think the reset might have helped as the distortion has not happened since.
