<div style="line-height:1.7;color:#000000;font-size:14px;font-family:Arial"><div>Hi,Alex</div><div> Recently, I bought another platform with i3-6100U to passthrough the GPU. The platform has only DP or HDMI output. I am very happy to success to passthrough igd and the usb controller. However, when the windows7 safe mode interface happens, the GUI is divided into three parts. And the keyboard is invalid. After the windows7 desktop occurs, the GPU and usb devices can run very perfectly. Did you meet this problem?</div><div><img src="cid:73b9bc9e$3$15756cb6ce3$Coremail$fulaiyang$163.com" style="line-height: 1.7; width: 992px; height: 649px;" orgwidth="992" orgheight="649" data-image="1"><img src="cid:270e646d$4$15756cb6ce3$Coremail$fulaiyang$163.com" style="line-height: 1.7;
