Since my monitor (Shimian 27" inch IPS monitor) does not have a DP port, I had to purchase a rather expensive adapter to connect it with the Vega 56.
It actually works okay when I don't have any Radoen drivers installed. However, when I install latest Radeon drivers (also tried blockchain drivers), static artifact takes over the entire screen (I can still somewhat see the what's underneath). Like this:https://ibb.co/eGYMLz
Only resolution is to uninstall the drivers, but then I can't play any games and have also stability issues.
I tried to setting the refresh rate on Radeon settings, with no avail. My guess is that the adapter isn't able to "handle" the latest features on Radeon drivers?
Hey dude, this is literally the first i've heard about this sort of problem. I'm sorry to bother you with no solution but i must highlight the fact that I am no tech advisor, however I do know how to google and i'm googling away now. Is this what you bought? https://www.startech.com/media/products/DP2DVID2/PDFs/DP2DVID2_Datasheet.pdf i'm looking for information/specs/compatibility issues with the cable and/or potential software needed to support it but i've had no luck yet. If there is anyway you can add more detail about the problem, it could help. So could this:
Did you follow these steps careuflly?
1.With the computer system powered off, plug the DisplayPort® connector from the DP2DVID adapter into the computer’s video card.
2. Connect the USB connector from the DP2DVID adapter into a USB port on the computer system.
3. Connect a DVI-D (digital) cable from the DP2DVID adapter to your display. NOTE: For 2560x1600 operation, a dual link DVI-D cable must be used.
4. Power on the monitor followed by the computer system.No software/driver installation is required.
Some troubleshooting method's you can try if you have the required components:
When you troubleshoot issues with a video adapter, there are some quick tests that you can complete to rule out potential problems. You can test to make sure that the following components are working correctly and are not the source of the issue: Video cables, Video adapter, Video source (such as a DVD player or computer), Video destination (such as a monitor or projector). To test your setup components, try the following: Use the cable, video adapter, video source, and video destination in another setup to see if the problem is with the components or the setup. Use a different cable, video adapter, video source, and video destination in your setup to see if the problem persists. Ideally, you should test a component that you know works in another setup. When you test your cables, it is recommended that you do the following: Test each cable individually. Use short cables when you are testing. When you test the video source and video destination, it is recommended that you do the following: Remove the video adapter from your setup and test to make sure that the video source and video destination work together without the video adapter. Test to make sure that the video source and video destination work together at the resolution that you want to use. Note: In order for your setup to work properly, the video source, adapter, and destination all need to support the resolution that you are using.
