T540P / GTX 970 / EXP GDC Beast
T540P - i7-4810MQ
iGPU: Intel HD Graphics 4600
dGPU: Nvidia 730m
eGPU: Nvidia 970
Nvidia Driver 385.41
Windows Home 10 17134
I've spent the last few days fiddling with this setup, I had some error 12/43 issues which I overcame using the custom DSDT and eGPU Setup.
I now have my 970 in device manager with no errors, PCI Express Root Complex under the large memory section in device manager.
The issue I am having is I cant get any applications to see the eGPU and also the HDMI /DVI port on the 970 is not outputting any video. I tried going into the windows graphics settings and setting MSIAfterburner.exe to high performance but that had no effect.
I also cant seem to disable the iGPU
Thanks for any hints.
Hello, sadly I don't have an answer for your question but I do have ab additional question.
Did you use m.2 interface for eGPU?
I am looking for T440p/T540p eGPU, and wondering if expresscard is the only option.
Thank you in advance!
Hi nino, I'm having the same problem:
Seems like you just can't disable optimus in modern ThinkPad bios?
