Scale up from 1080 to 1440p?

[SπdR]

I'm using this to scale up a full screen OBS streaming Nintendo Switch. How do I upscale to 1440p?

You set the display to 1440p, the game to 1080p windowed or non-fullscreen borderless and use scaling type LS1, SGSR, FS1 to bring it to 1440p fullscreen.

Can't really offer help but I'm wondering:
Why not emulate, if you're looking to play a Switch game at a higher resolution?

- Put game in windowed 1080p mode
- Tab to the scaling application, press scale, tab back to the game within 5 seconds
- It will automatically scale to your monitors current resolution, which should be 1440p
- If you want to increase the max fps then enable frame generation at x2 or x3, not sure whether it works with streamed games but I ♥♥♥♥ you not I'm playing Skyrim with 3500 mods right now and sitting at 120fps in places where I was sitting at 60 without it. You still get stutters but you can iron those out by capping your max fps to a lower value, and it will still be doubled or tripled.
