Question Third monitor Detected but cant display anything on Windows 11

[GlobackX]

Hi everyone, I just bought 3 4K 160hz displays but when I connect them ( all three with dp 2.1) only 2 work the other one is detected but doesn’t display anything (when i disconnect one the other jumps ons and works fine) I’ve tried doing NVIDIA surround but when I enable it it just reboots my pc and turns surround off again. I’ve tried lowering the resolution , Hz and turning HDR on and off but I can’t get the three monitors to work simultaneously. I have reinstalled the Drivers ,Reset the monitors (and deleted them from device manager) used different cables (connecting them in order) etc. i tried it on Linux (ubuntu) and it worked fine 3x 4k 144Hz. but on windows 11 only 2 display anything at one time. Any help is appreciated.

System information:
Windows 11 10.022631 Build 22631
(Fresh windows install)
Nvidia Driver 560.70
(removed and reinstalled it a couple times)
Bios version F4

Are all three monitors listed in Device Manager?

Check the properties window and all four tabs within the window for each monitor.?

Gainward: this GPU?

Gainward GeForce RTX™ 4070 Ghost OC

As I understand the photographs and specs there is one DP port and 3 HDMI ports.

https://www.gainward.com/main/vgapro.php?id=1182&tab=ov&lang=en

Connectivity	DP 1.4a x 3 HDMI 2.1a x 1

However, you posted "but when I connect them ( all three with dp 2.1) only 2 work the other one is detected but doesn’t display anything (when i disconnect one the other jumps ons and works fine)"

Exactly how are the monitors being connected to the GPU? Any adapters?

Have you tried Gainwards listed drivers?

ALL video adapters have a maximum horizontal resolution. You've obviously exceeded what your video hardware can support. What does your documentation tell you?

All 3 monitors are listed in device manager, and yep that GPU, its 3x dp 1.4a (there is only one HDMI) the monitors are directly connected with DP2.1 to the GPU, and yes ive tried the gainward drivers, still no change

the documentation says 4x 4k 120 but ive tried 3x 1080 60 with no hdr but i still can only use 2 at a time, and theyre connected with dp 2.1 straight to the GPU there is nu adapter in between
