I'm running Mojave 10.14 with an AMD Vega 64 that has 1 HDMI and 3 DP ports in an eGPU. I've been using the HDMI port for a while and decided to have another monitor. Since I only have HDMI monitors and 3 DP ports left, I got a DP to HDMI adapter. To my surprise, it doesn't work. I've googled a bit, but I've majorly stumbled on hackOS threads and such, not sure if it would be applicable to my situation. I'm thinking either my adapter doesn't work or it's something software related. Is it supposed to work out of the box?

Anybody else had this issue before?

I have a DP -> HDMI adapter that I sometimes use when using a VR headset + HDMI monitor and it works fine. You may have a DOA adapter, or the adapter might not support the version of HDMI your monitor is expecting.

I've tried two different adapters so far, both not working. I doubt the adapter is DOA. I've tried HDMI to HDMI, and both monitors seem to work fine. And what do you mean HDMI version my monitor is expecting? If there's an incompatibility, the conversion won't work? On the product page, it says it converts to HDMI 1.4.
