Custom Resolution Utility (CRU)

In fact, there's a registry value for scaling in HKLM/System/CurrentControlSet/Control/GraphicsDrivers/Configuration/(monitor name)/00/00 (2 = centre image, 3 = scale full screen and 4 = maintain aspect ratio). How is downsampling being or not a feature determined? Would a custom .inf file with a higher height/weight (or both) than the native resolution work (e.g. replacing 1366x768 with 1367x800 or something like that)? Or creating a custom EDID with width and height values as 1367 and 800? (There's a tool to create/edit custom edids called AW Edid Editor) If it matters, I do know about a registry key for downsampling in lower resolution monitors (and even 1280x800 and 1366x768 ones) that adds 1152x864 and only works with intel gpus. If you don't know (most likely) how is that possible I'll ask how in the Intel Community and how is VSR limited in AMD's counterpart. I'm lazy to test stuff.

The GPU has a scaler. The laptop screen does not. CRU is already an EDID editor. Changing the EDID doesn't change what the hardware can do. The laptop screen can only accept the native resolution, so you can only scale with the GPU. The GPU's driver has to offer a way to scale down a higher resolution. How would you do it with an Intel GPU?
