Hello, new here, but i couldnt help but notice that everyone is having issues with windows 8.1 and SLI configuration. I would like to start of saying that this is NOT a "oh, SLI works with mine, I don't know why you all are having problems" kind of post. I merely wish to post my system information and any other information anyone would request that could assist in possibly finding a fix for the SLI issues, whether or not SLI is actually working, and why my experience has been different from everyone elses. I also apologize for my poor formatting. Also, cool info is that the 750m's here are the rarer gddr5 versions, making them significantly faster than the ddr3 versions. Good job lenovo.

The only thing different between the internal and external GPU are the bios versions. Things are blurry because windows fails with >96ppi displays (come on microsoft). Please reply with any questions or comments.
