I upgraded my Medion Akoya Sandybridge laptop from Win7 x64 to Win10 x64 last year and have been living with this issue for a while as it's my HTPC connected to my TV. In a nutshell, all was well on Win7. All is well on Win10 when it is connected to my TV. When I try to use it as a laptop without an external display connected, after the Windows flag boot up screen, the laptop display remains blank. I hear the Windows logon chime, but still nothing shows on the laptop screen. I can plug in the hdmi cable and the laptop displays the desktop on the TV fine. I understood after upgrading that Intel aren't developing Win10 drivers for this chipset anymore and was fine with that. However, having purchased a nvidia Shield TV on yesterdays Amazon Prime day, I'd like to use the laptop as a laptop. If I uninstall the display device and reboot, the Microsoft basic driver is used and that works fine on the laptop, but not on the TV (if I recall testing late last night correctly). By any luck, might anyone here be aware of any drivers for Intel HD 3000 that let you use the laptop screen? Thanks in advance!
