what about the inf? i think it won't affect anything because "maxresolution" is 1600,1200?

The laptop panel can only display the native resolution no matter what, and a monitor .inf file does not affect GPU scaling. GPU scaling is controlled by the graphics driver.

There is no scaler other than the GPU scaler which is built into the GPU. External monitors usually have a separate scaler chip on the board with the inputs, but not all of them will accept higher resolutions either.

That's weird because Intel's official stance is they don't support downscaling resolutions. That value is specific to Intel's driver, and I don't know anything equivalent for AMD.

The GPU could theoretically do it, but you'd need some way to make the GPU's driver do it, and the only official way I know with AMD GPUs is using VSR, which AMD intentionally limited for some reason. There was another method that involved creating a custom resolution in AMD's control panel (if it even lets you with a laptop) and then finding the custom resolution in the registry, which is in binary format, and then hex editing the resolution values while leaving the active pixels alone, but AMD's registry keys have changed over the years, and the paths are specific to the monitor, so you'll have to figure that out yourself, if it's even possible anymore.

I don't have AMD's control panel but I know that in Adrenalin it's not possible to create a custom resolution in it.
On Intel and downscaling, it's only possible in the registry, but not the control panel. The registry key just adds 1152x864 and 1024x768 in 1024x600 monitors. I'll try things tomorrow. I won't ask the amd/intel communities though.

On your answer to "4", AMD's equivalent is the aforementioned DALNonStandardModesBCD1/2/3/4/5 in the same location as Display1_DownScalingSupported. In my laptop though it only adds 16:9 resolutions (I recently tried it with 1184x666. 1280x960 (the default mode) is 4:3 and it's not even there but the height isn't to blame), similar to your SRE utility. 1184x666 is the only resolution I tried and added via this method though and 1366x768 is close to 16:9.

UPDATE: I asked the original question to the Guru3D forum and if it's DEFINITELY impossible then I won't test anything.
