How to setup a virtual super resolution - Ilyaki/SplitScreen GitHub Wiki

On the multiplayer beta, resizing windows smaller than 1280x720 seems to completely glitch out (Unless you install https://www.nexusmods.com/stardewvalley/mods/2266 (Window Resize mod)). On a 1920x1080 monitor like mine, this means the windows won’t fit on the screen without overlapping. A workaround is to use a fake higher resolution scaled down. Most applications may look slightly blurry, but Stardew Valley looks sharp once you have set zoom in-game correctly

On AMD GPUs

  1. AMD settings -> Display -> check Virtual Super Resolution and GPU scaling. Then set the resolution to something like 2560x1440 in Windows display settings

On NVIDIA GPUs

  1. Right click desktop -> NVIDIA Control Panel
  2. Open Display -> Change Resolution -> click Customize -> click Create custom resolution
  3. To set resolution to X by Y, set Horizontal Pixels to X and Vertical lines to Y (I would recommend either 2560 by 1440 or 3840 by 2160)
  4. Click Test -> Yes to changes -> Ok
  5. In the list of resolutions, select your new custom resolution, click Apply -> Yes to changes
  6. Done. If you want to quickly switch between resolutions now, you can go to Windows settings -> Display -> Resolution

On Intel GPUs

  1. Right-click desktop -> Graphics Properties -> Display
  2. Open Custom Resolutions -> Add
  3. Set Width to new width in pixels and Height to new height in pixels. (I would recommend either 2560 by 1440 or 3840 by 2160). Set Refresh Rate to 60
  4. Open General Settings and select your new custom resolution in the Resolution menu
  5. If you get an error 'This resolution exceeds the maximum bandwidth capacity', try updating your display drivers. If this does not fix it, try plugging in your laptop/computer into a secondary monitor, then use the AMD/NVIDIA instructions depending on which discrete GPU you have
