Black Screen/3 dots issue. (Hardware Notification) Oculus Problem For Oculus Link/Air Link
~First Troubleshooting tip: -Open Device Manager > Device Adapters (Mind you this only applies if you have Integrated Graphics) > RIght Click on the Integrated Graphic Unit > Disable Unit (This will refresh your computer, Display Wise) Restart Both your Comptuer And Quest/(Or whatever headset you're using) And try Link again.
If It doesn't work then
Second TroubleShooting Tip -Go to your PC Oculus App > Go to Settings > General > Make Sure Unknown Sources are Turned ON
Third TroubleShooting Tip -Go Into your PC settings > Graphic Settings > Browse > C:\Program Files\Support\oculus-runtime > Add all three OVR Services > Click on them After > Options > Set to High Performance
Fourth TroubleShooting Tip -Make sure your Graphic Drivers ARE UP TO DATE! This has gotten me to have my Air Link work, But This also works for Oculus Link as well!
What I've looked into is that if your computer has a integrated graphics card, Try disabling that in Device manager. And try it again (You may have a weird display afterwards, Which is normal)
You may have to re-enable Airlink on your Oculus App on your PC. Try it from your headset again.
If it works, Great!
If not, I'm sorry.
After it works, Re-enable the integrated graphics card. And you should be good to go.
