Home / windows 8.1 hdmi not working Windows 8.1 hdmi not working 30/03/2021 I freshly purchased a new lappeak via Windows 8, which I had never before tried prior to (so I am new to this). I updated to 8.1 the various other day, and afterwards I tried connecting the lapheight to a brand new LG HD TV with the HDMI ports. I opened the "Project" menu and schosen "Duplicate", and while I check out somepoint readjust on my laptop screen (it flickers, and the resolution/colours change), the TV picks up no signal.You watching: Windows 8.1 hdmi not workingThe HDMI port on the TV is working properly (tried it with one more device), and so is the HDMI cable. Tright here is some kind of connection happening because the TV enables the HDMI input only once somepoint is detected on the other side of the cable.I have checked out that it could be a well-known worry with Windows 8.1, yet I can"t uncover a solution anywhere. My laptop has actually an incorporated Intel GPU and an nVidia GeForce 740M, and also I believed perhaps the trouble was that it uses the Intel card as a conventional, only switching to the nVidia when important, yet the HDMI is "controlled" by the nVidia. So I"ve tried disabling the integrated GPU (to no avail - it simply switches to the classiccomputers.info Basic one rather than to the better card - this has actually been checked through dxdiag), and also uninstalling and also reinstalling the nVidia drivers (which were up to day to start with). I have checked the BIOS to check out if I could adjust the priorities, but tbelow was no alternative prefer I check out on my Windows 7 desktop.Is there anything else I have the right to try? It appears really silly to me that I cannot use the HDMI output at all!Thank you for any type of assist. This thcheck out is locked.
