R9 390 4K issue

[meenmeen1103]

So I have a system with an XFX R9 390 that I'm trying to hook up to a newish Samsung 4K tv, not a gaming setup. Originally it worked through HDMI but at 24-30hz, but tried to get 60hz out of it by using an active displayport to HDMI adapter supposedly rated for 4k60fps. Didn't work (would get screen flickering past 30hz) but I read on forums that it could be due to driver issues, and went about booting into safe mode, deleting the c:/AMD folder, running DDU, then downloading and installing two different known working driver versions for this use case, but I now only get like 2 seconds of display after booting into desktop then black screen. Same thing even after removing the active adapter and just trying to run direct HDMI with the settings already saved to 4k30hz. What gives?

Display Port to HDMI 2.0 is incredibly new and likely to have issues in general.

Last I checked only Club 3D made a display port to HDMI 2.0 adapter with limited success?

Yeah that's understandable, but my issue here is I can't even keep a video signal anymore using only HDMI at 4k30hz like I had before trying the adapter/other drivers

Did you try a different HDMI cable? Or a different port on the GPU? Or a different monitor from the GPU?

Ok so I had tried a different HDMI cable, the gpu only has one HDMI out, and haven't tried a different monitor. The thing I find weird is the HDMI cable, and monitor that were previously working are not working properly now

What cable are you using ? I have an active adapter by plugable on my 290x , works fine. 

 

But this seems to be a driver issue. 

If you have your card overclocked through afterburner ,try holding control once you get on the desktop until afterburner launches . Sometimes an existing oc doesn't play well with a driver install.

Took the adapter off and using a 2.0 spec HDMI cable, tried a 1080 monitor too had same issue. Haven't had an overclock on it for over a year. Ran DDU a fourth time and rolled back to a driver from 2016, now working with the 4k panel at 30hz through just HDMI (no adapter). Looks like I need to try a different adapter to get 4k60hz out of this gfx card. The easier thing would be to just have natively compatible hardware but it would cost just as much to replace the 4k panel with similar one with displayport as it would to replace the gfx card with similar one with HDMI 2.0 output right now lol

Update: managed to locally trade a 1080 monitor for a strix gtx 970 with HDMI 2.0 out, working perfectly at 4k60hz, now to put the r9 390 for sale
