Hi,
Dell OptiPlex 3060 with a Visiontek Radeon RX 550 (4 x HDMI). Have tried with Adrenalin 23.11.1 and 34.3.1 (actual).
Do not have HDMI monitors now to test it so I am using HDMI to DVI and to VGA. The desktop's integrated Intel UHD Graphis 77 is active and must remain active as the intended configuration is for the Intel to handle the main monitor and the AMD to CLONE 3 others into a single output.
Have run Dell diagnostics and DXDiags and all tests passed.
The only STABLE AND CONSISTENT result I get output on HDMI port 2, only. If I move the adapter from port 2 to other HDMI ports, the same monitor goes into power save mode and no image, of course. I ran the AMD removal tool and after a restart, before re-installing Adrenaline, with Windows drivers, I got briefly output on HDMI port 1.
Any ideas are highly appreciated.
PS: Couldn't find a way to attach the DXDiag results.
