Using internal display on iMac for windows 10?
Update: It's iMac 2015 Late, not 2016
- Installed the latest Nvidia driver
- Disabled internal intel GPU
- Nvidia utility says eGPU is powering Internet Explorer
- If I run 3D games in full screen mode, frame rate is 2 ~ 3 fps.
Can someone please give me a direction to solve this issue?
Thanks in advance.
What are the specs of your 2015 iMac? In order for eGPU internal display mode to work, the Intel iGPU has to be present and active.
If you see both the Intel Iris Pro iGPU and Nvidia GTX 1070 eGPU in Device Manager without any yellow triangle, internal display mode should work. Do you see an icon like this in the taskbar?
It only works when the overwatch uses "Window mode," not "full screen mode." 🙁
In 'Configure Surround, PhysX' there is no internal LCD in the chart, only the external monitor.
Did you ever solve this problem? I have the exact same hardware (iMac 4k Late 2015 - Iris Pro 6200 iGPU only) and cannot get the eGPU to run applications unless I:
1) Connect an external monitor to the eGPU
2) Disable the internal display
Otherwise, I get the message that the eGPU cannot be used because there is no display connected to it. It is a shame because it turns the machine into a gaming beast. Unfortunately, I can't get it to work with the internal display, which was the whole point.
I also tried installing (and uninstalling) multiple drivers - the Gigabyte Nvidia drivers, Official Nvidia Desktop drivers, and Official Laptop drivers. All gave the same result.
I'm starting to think it has something to do with the Intel display drivers. Both display adapters always show as Active in Device Manager. However, Intel does not list the Iris Pro 6200 as offering Switchable Graphics. Seems like this would be a problem for Optimus to activate?
The following Intel Graphics support the Switchable Graphics feature if enabled by the computer manufacturer:
- Mobile Intel® 4 Series Express Chipset Family
- 1st Generation Intel® Core™ Processors with Intel® HD Graphics
- Intel® HD Graphics 3000/2000
- Intel® HD Graphics 4000/2500
- Intel® Iris® Pro Graphics 5200, Intel® Iris® Graphics 5100, or Intel® HD Graphics 5000/4600/4400/4200
I will certainly keep you up to date on my findings...
