Windows 10: Triple Monitor Setup No Signal

I have a triple monitor setup, but only 2 out of the 3 monitors are on simultaneously. Whenever I plug in the third monitor another one shuts off and gets the no signal detected message. If i unplug one the other one starts working fine, two out of three stay on, but whenever I plug in the third one, one just shuts down and gets the no signal detected message, while the other two are working just fine. All cables are connected properly, working fine, and all ports are working aswell. I'm with a 4090 GPU, using 2 x HDMI cables, 1 x Display Port. Tried even converting one of the HDMI cables to D

Triple monitor setup, monitor going on and off when a new screen is being detected the first time

Hi Greg,

Thank for your reply, unfortunately I already search a lot before posting here and I saw already a couple of posts with these troubleshooting steps from you
I did them all before posting and none seems to work for me.

To be clear none of the problems listed in all these links are describing my issue.

Maybe my problem is "normal" in a certain way, because I'm starting a computer with 1 or 2 screens so windows will start with a single or a double monitor setup. But when I'm switching the input on the third monitor to be connected to the computer that I just turned on then it does switch to a triple monitor setup.

But instead of just reordering the screen as they were saved smoothly it's like all the screens are going crazy for like 30 seconds by turning on and off . During this craziness, on Win11 also the desktop is like minimized (like i'm pressing the button to add a new desktop). And after like 30 seconds they are all going back to normal working properly.

It's really in these context that the problem occur : when windows starts as a single or dual monitor setup and when it's started I'm adding a new monitor.

Note: If i'm starting the computer with all my 3 display connected properly to the computer there is no issues. Windows will start as a triple monitor setup correctly.

 

Impaired mouse movement in triple monitor setup [Windows10]

[Windows10] imgur.com This is currently my triple monitor setup and im able to move the mouse without problems between Monitor 1 and 2 - and between 2 and 3. Im unable to move my mouse between Monitor 1 and 3 for some reason. Is there some fundamental reason within windows that makes this impossible or did I make an error during setup?

 

Double Monitor Setup is not connecting

Hi Yuri,

To setup dual monitors, I suggest you to press Windows + P keys
and select Extend or the required option and check for status. If you are still unable to setup dual monitor, suggest you to update the Display Adapter driver by following the steps provided below and check for status.

• Press Windows key + X and select Device Manager.
• Expand Display Adapters.
• Right click on the driver and select Update Driver Software.
• Follow the on-screen prompts to update the driver.

Hope this helps. Keep us posted on the status for further assistance.
