This means you must choose a version which support WDDM 1.1 and it support 6th or 7th CPU at the same time. Finally I did some research the about the display drivers difference between winows 7 and windows 10.īasically, the display drivers support windows 7 must follow WDDM 1.1, but on windows 10 it support WDDM 2.0+. I do a lot testing work to test different version.I try to merge some of them but all of them couldn't work stable enough. I must say this is not easy, you need some hacking background to understand how it work.įirst things, choose a right driver version. I try all methods in the post found the same issue, so I try to dig into this problem, and finally I hack the driver binary file(DLL file) successfully. This way looks work, but not perfect, I found when I playback video, player always crash on my UHD 620 (Embedded in I7 8550U), whatever I used.Īnd someone said replace some dll file will let playback work normal, but 3D function couldn't work, like this guy: I use nvidia 397.64 driver on my MX150.Īs you know Intel didn't support graphics drivers for 7th and 8th CPU on windows 7, I do lots of research on web found some inf hack to resolve it like this: install/reinstall the discrete video card driver, not recommend a newest one. Find the file igdumdim64.dll, edit it by a hex editor, like winhex or ultraedit. Find the file igdumdim32.dll, edit it by a hex editor, like winhex or ultraedit. Add this line into windows 7 install section Do the inf hack, looks into the Graphics directory, find the file igdlh64.inf, modify it. This is the quick step, if you don't want read more:Ģ. ![]()
