So I've had this laptop for quite a while. Upgraded its GPU twice now. Currently have a GTX 1060. When I upgraded to windows 10 from windows 7, it seemed to break a lot of features on this laptop. Such as the headphone and mic jacks not working. Since I upgraded the gpu and switched to windows 10 nearly at the same time, I don't know which one might have broke the HDMI in feature but after I did, the sound from the HDMI In stopped working. "HDMI In" just up and vanished one day under "playback devices" even though I saw it in there working fine after the upgrades were said and done. While the sound stopped working for whatever reason, the screen still worked fine.
Now upon my second GPU upgrade, the HDMI In doesn't work at all. It's just a black screen. If I plug external speakers to whatever console I'm trying to connect I can still hear the console outputting stuff just fine. I understand this is probably a driver issue and that the GPU isn't compatible with the screen hdmi in screen. But I was wondering if anyone knew of a possible fix before I write-off the HDMI In feature on the laptop completely.
