Trouble with AMD Eyefinity - 5k2k Display and 2x LG Dualups

Greetings AMD Community!

I am (hopefully!) a proud convert to team red after spending years with team green. The major reason for the change was to use the Eyefinity with monitors of different resolutions. Reading the documentation, I understood the feature to allow the usage of monitors of dissimilar resolutions, but it would create a single display using the single lowest vertical resolution and then could "fill" to create a consistent horizontal screen. 

I have been unable to get this to work. 

  • Central Monitor: LG 40" 5k2k - Part Number 40WP95C-W - 5120 x 2160 
  • Flanking Monitors: LG DualUp 28" - Part Number 28MQ780-B - 2560 x 2880
    • All monitors are connected via DisplayPorts

They were picked specifically as they have the same pixel density. The flanking monitors hang slightly lower to the desk than the main one. Its a great work set up and was really hoping it would be a good gaming set up too.Using Eyefnity - I theoretically should get a maximum resolution of 10,240 x 2160.  However, the only resolution that it comes up with is 7120 x 1080 in a "fill" setting.

Trying to use Eyefinity Pro, it will only allow me to create a fill and pops up the error code of incompatible setup. Fit and stretch do not work. 

Software Details: 

  • Windows 11 - fully up to date.
  • Adrenalin - fully up to date
  • All monitor Bios and firmware up to date. 

Hardware Details - No Overclocks - All Are Up to Date: 

  • PowerColor 7900XTX Graphics Card
  • AMD 5800X3D Processor
  • Corsair 32GB 3200 Mhz RAM 
  • AsRock MiTX B550 Phantom Gaming Motherboard
  • Samsung 500GB NVMe2 Boot SSD
  • 2x Samsung 1TB RAID SATA SSDs in RAID 

All monitors work perfectly in "normal" Windows 11. 

Any thoughts on how I might get this setup to work in Eyefinity? I've searched forums and can't see to find anything that works. 

 

Thank you!

I’d like to add a few steps I’ve taken in the interim. Did a clean install of Windows and attempted to troubleshoot with a single side monitor. 

Third, attempted to span just to the side monitors alone. Same issues.
