I'm having an issue getting my computer to display in the correct resolution. In the windows display settings I have the option to select 1360x768 which is the correct resolution, but I can very clearly see that it is not displaying in the correct resolution. It doesn't look right at all. Is this a driver issue or a conflict with windows 10 perhaps? I have already manually selected my drivers multiple times and used multiple different versions. Nothing seems to be working unfortunately... I'll attatch a DxDiag here. Thanks in advance for any help!
I downloaded the Manual for your Motherboard and upload the Graphics part of the BIOS. It may not be the same since you updated the BIOS your computer. But should have something similar.
Is it possible when you have the AMD GPU card as default (PCIe 1 Slot) that the Intel integrated Graphics is disabled? Which might explain why you can't install the Intel Graphic drivers. That why you need to check to see if "DEVICE MANAGER" shows your Intel HD 630 active.
AS A LAST RESORTS ONLY: You can repair your Windows 10 by running a Ingrade Repair. Download Windows Media Creation Tool and use it to either create a .ISO file (to burn to a USB or DVD) or burn it onto a USB Flash driver (8 gigabyte or bigger) or DVD disk.
Install the USB Flash or DVD with the Windows 10 (version 1803) installation while on your Windows Desktop. Run the installation. Make sure to check the box that says to keep all personal information and apps. Once it finishes reinstalling WIndows 10 see if the Intel Graphics is installed and showing in Device Manager and AMD GPU card also.
Note: I did this same Ingrade Repair on my computer a couple of weeks ago and Windows has been running great since then. I was having a huge amount of DCOM permission errors (Windows Event Viewer) that was causing my Windows to freeze intermittently every few seconds. Re-installed Windows and all my errors pretty much disappeared.
You mentioned that you installed the latest Intel CHIPSET from Gigabyte Support, Correct? Then your motherboard CHIPSET should be up to date.
You can run Windows Cleanup to delete Windows.old to clear space on your hard drive. But I believe after 7 or 10 days it will automatically be deleted.
