Custom Resolution Utility (CRU)

I'm trying to use CRU because I can't DSR with an Optimus enabled notebook (my display is attached to my iGPU and I have an RTX 2080 dGPU). I can't view any custom resolution or DSR related settings in the NVCP and I need to make custom resolution to gamestream 4k to my TV's shield.

I have a GE75 Raider MSI notebook with a 1920 x 1080p, 144hz native display.

I have made a 3840 x 2160 @60hz within CRU with no problems. I have done this with standard, native, and even reduced timing. I run the restart tool and reboot my computer where the display option is shown in Windows and my Intel Graphics Command Center where my display settings are. I can set it to my new custom resolution, it's crisp and clear, no flickering, or blackouts, but it's zoomed in and only showing the top left hand quadrant of my display.

It doesn't matter if I set my Intel's scaling settings to stretched, center, maintain aspect ratio, or maintain display ratio. I do not know what the cause of this is. I don't know if back porch, front porch, sync width, etc... could have anything to do with it, but I have tried multiples of x2, x4, and used all the automatic timings. I have also tried 73.XXXhz, 60hz, 30hz, and 15hz If anyone could help me scale to fit, I will be very grateful.

CRU does not create scaled resolutions. You are sending 3840x2160 to a 1920x1080 display, and the display hardware is deciding to show the upper-left portion, not the software. You also don't want 3840x2160 to be the first detailed resolution because that is considered the native resolution, so it's never scaled. If GPU scaling is enabled, other resolutions will be scaled to the first detailed resolution, but I don't know if Intel GPUs will scale down higher resolutions. AMD and NVIDIA GPUs will only scale lower resolutions with GPU scaling enabled.
