Display port issues on Cubi-N

[drtechn159002e3]

Hello, I am having some issues with my display port. I'm using a display port to hdmi adapter. This is a known issue with display port to hdmi adapters.
Intermittently when I turn the computer on, or wake it up, the monitor with the display port doesn't wake up.
Is there a flash for the display port firmware to solve this issue like there is for Nvidia cards?
Because its not driver related nor is this an issue with the display port to hdmi adapter.

Please use HDMI cable or DP cable directly.
Don't use adapter.

So who made the display adapter? The model number is Cubi-N ADL-01BUS.

Discontinued using the display adapter. The issue is still present on the HDMI port.
