Intel Arc 750, dual display issue through DisplayPorts

[James - older than before]

New PC Build over the weekend, all new parts ...

 

Motherboard: Asus ProArt B760 - Creator D4

CPU: Intel i9 12900K

RAM: G Skill Ripjax DDR4-3200

Power: Corsair RM850x 850 Watt, 80+ Gold

GPU: Intel Arc 750 Limited Edition

Drive: Samsung 980 Pro, 1TB, M.2 NVMe

Displays: Asus ProArt PA278QV, x2

 

Put it all together on Sunday and turned on like a charm.  Display outputs from the MOBO (1 HDMI and 1 DisplayPort) worked just fine to get me in and update BIOS to latest version, install Windows 11 Pro - 64bit and fully update, and install / update all drivers.

 

Installed Intel Arc 750 and got only one display working with DisplayPort cable ... the other showed "No Signal" and not detected by Windows.

 

Reseated, same issue.

 

Tested other cable, worked fine (but still only one display).

 

Tested one monitor at a time ... each cable on each monitor ... all three available DisplayPorts on the card ... worked like a charm each time.

 

Plug in the second monitor to a DisplayPort and get "no signal" error.

 

Plug in the second monitor using HDMI port on the card, works like a charm.

 

Thoughts on why the card can't seem to drive signal to two DisplayPorts at the same time?

 

Thanks!

You ever get this resolved? I've been looking more into Intel Arc's viability and stumbled upon this thread.
