Cannot Get Dual Ultrawide Displays to Work Unless I Start PC With Just 1 Then Plug Other In After Login

Oct 13, 2018
Sorry if the title lacks clarity.

My problem concerns connecting two 25" ultrawide displays. I am only able to get both displays to work properly when I start my PC with just 1 display plugged into my graphics card then, upon signing into my account, plugging in the second cable to my graphics card.

2x LG 25UM58 25 inch Ultrawide IPS Monitor (2560 x 1080, HDMI Out)

GPU: EVGA GeForce GTX 1050 SSC GAMING ACX 3.0, 2GB GDDR5, DX12 OSD Support (PXOC)
CPU: AMD Ryzen 7 1700 3.0 GHz Eight Core AM4 Processor
Mobo: MSI ProSeries AMD Ryzen B350 DDR4 VR Ready HDMI USB 3 micro-ATX Motherboard (B350M MORTAR)

The displays are connected to computer as follows:
Monitor A HDMI Out -> HDMI-HDMI -> HDMI In on GPU
Monitor B HDMI Out -> HDMI-HDMI -> HDMI-Display Port -> Display Port In on GPU

I have had success keeping the Monitor B set up plugged in, starting up my computer, logging in, then plugging in the Monitor A setup.

The HDMI-Display Port adapter is PASSIVE. I cannot find out whether this is causing the problem, but my intuition says that if I can start the PC and use the Passive cable fine then there must be a working solution so I don't need to unplug then replug in my cable every time.

Please also note that as soon as I put my PC to sleep, neither monitor works.

Prior to this set up I was running 3x 1920x1080 displays fine.

I would appreciate any insight into this problem.

Thank you very much,
