kasten Posted January 27, 2013 Share Posted January 27, 2013 When I try to open the NVIDIA Control Panel when my eGPU is connected I get "You are not currently using a display attached to an NVIDIA GPU". I am just using a eGPU for a 4 monitor setup which works fine other than everything is stuck rendering with the iGPU. How do I force a GPU to be used for rendering? My system specs: Prostar (Clevo based) P151EM1 CPU: Intel Core i7-3610QM Chipset: HM77 GPUs: GTX 670M(dGPU), Intel HD Graphics 4000(iGPU) and ATI HD4350(eGPU for more monitors) OS: Windows 8 64bit (I have also tried Windows 7 64bit) All 3 GPUs show in the device manager and show no errors.

Northern-Loop Posted March 1, 2013 Share Posted March 1, 2013 Bump I also have this problem. The my EGPU unplugged Nvidia Optimus works fine. I have tried disabling my dGPU but still says the same error message. Link to comment Share on other sites More sharing options...
borealiss Posted March 1, 2013 Share Posted March 1, 2013 I ran into this problem sort of, but was able to use the output of the egpu as an extended desktop card.when you try to set resolution and monitor setup, does windows show more than 1 monitor?

rhx123 Posted March 5, 2013 Share Posted March 5, 2013 Interestingly, I have this problem with my 8600GT (test card) in Windows 8 64 bit, but not Windows 7 64 bit, Link to comment Share on other sites More sharing options...
Northern-Loop Posted March 5, 2013 Share Posted March 5, 2013 Interestingly, I have this problem with my 8600GT (test card) in Windows 8 64 bit, but not Windows 7 64 bit,As far as I can tell it's caused by Windows still seeing the dGPU and thus Nvidia control panel is getting confused.Happens in Windows 7 and 8 for me.Sent from my Nexus 4 using Tapatalk 2 Link to comment Share on other sites More sharing options...
rhx123 Posted March 5, 2013 Share Posted March 5, 2013 I don't have a dGPU, I just have the Intel card. (X220t) FYI, If I don't use the hibernate->plug->unhibernate in 8, this happens over and over (the internal screen goes black and off) Under Windows 7, I can boot with the dGPU plugged and it all works first time.

rhx123 Posted March 6, 2013 Share Posted March 6, 2013 An update on my side, wiped my HDD completely, re installed Windows 8, got my 650Ti and everything works perfectly. Link to comment Share on other sites More sharing options...
