Add 3840x1600 display resolution to windows 10 guest

Hi Guys,

I bought a new wide screen monitor recently. The native resolution is 3840x1600. When I connected to the virtual windows 10 guest, I found I cannot use the native resolution. I can do 2560x1600 or 3840x2160. And there is even a 3840x2400. But no 3840x1600. I have already set the display memory to 64MByte. Should be enough. I searched knowledge base and did find a document about add resolution. In that document,

VMware Knowledge Base

it said I should modify the windows registry and search for vmx_svga. But I didn't find it in my guest machine. I already installed the vmware tools.

Could anyone tell me how to do it? I'm using esxi 6.5

Thanks.
