Lose Intel Graphics when I close my T440p lid
 

I have a Lenovo T440p laptop with a Intel HD Graphics 4600 display adapter running Window 10 64bit OS.

The version of OpenGL is 4.3

When I'm connect my laptop to a ThinkPad USB 3.0 Dock my OpenGL Version Drops to 1.1 and I only have GDI Generic available.

Is there a way to keep my Intel HD Graphics 4600 active when I've got the lid closed? Before someone suggests it, it's not the "Control Panel\All Control Panel Items\Power Options\System Settings" as these are all set to "Do nothing".

Thanks for any help you can give.

Hello,

Unfortunately, the only way around this bug in the Intel graphics driver on Windows 10 is to get a direct display connected as primary display.
Intel fixed the new driver branch but didn't backport the fix to the older branch for older GPUs.

The Intel GPU is active. However, the OpenGL pass-through between Windows and the Intel graphics doesn't work properly if the primary display is not a directly connected display.

If you don't often reboot/restart, you could start your applications whilst the lid is open and then close it as, for applications like Google Chrome, the issue is only at launch.

Kind regards,
Alban
