ShadowPlay desktop capture resolution failure

monitorrecordingshadowplay

I have a nice pair of 4k resolution monitors, but I prefer playing my games in Borderless Windowed mode due to multitasking and frequent need to Alt+Tab.

So I have ShadowPlay recording the desktop, which is fine. The problem is, it's only recording at 1980×1080, shrinking down the 4k image in a way that loses a fair amount of detail (especially in-game text)

Does anyone know how to make ShadowPlay record the actual screen at full resolution, or will I need to use Fullscreen mode in-game to get that result?

It turns out that - due to the 200% scaling in Windows settings - the desktop resolution wasn't being reported correctly to ShadowPlay, causing it to record at what it thought was "in-game resolution" but in fact was only a fraction of that.

Changing the recording settings to "custom" and specifying 4k explicitly has resolved the issue, and I now get full-resolution recordings.

Thanks to @MadMrCrazy for pointing me in the right direction with what settings to look at!
