I don't think on-board Intel iGPU actually "reserves" 4gb of ram to itself. That would be bizarre. But anyway, with an Nvidia GTX-1050ti installed ... all monitors should be connected to the Nvidia card anyway.
im running my main monitor with a overclocked 1050ti and side monitors on my integrated gpu and i noticed according to windows my integrated gpu is getting 4gb of reserved ram? thats half my ram and way too much for just google and discord on side monitors so i was wondering how i would change that. xps 8300 i7-2600 with intel HD 2000 gpu asus gtx 1050ti 8gb 1333mhz ddr3
XPS 8300, change reserved ram on iGPU?
