So guys as the title says I'm having troubles for some time now with windows 10 not being able to detect my secondary display which is a LG lb650v smart TV connected through hdmi. Had this problem for a while with earlier builds and thought my cable died. But recently went back to win7 and there the TV works just fine. Then yesterday did a clean install of win10 x64 pro build 10586.494 and once again it doesn't detect any secondary display under display settings. My gpu is a nvidia gtx 560 ti and my primary display is a 22" monitor connected through DVI, while the secondary display device is the above mentioned LG LB650V tv connected through hdmi. I have the latest win10 nvidia display drivers (there's not even a newer beta version available), and windows update doesn't find any driver update. Also there's no driver missing from device manager. Any ideas how to fix this?
