The idea

On a 4K monitor with Windows display scaling at [150%], fullscreen looks noticeably
blurrier than windowed mode — it seems to render below native resolution and get
stretched by Windows. Resolution is set to 100% in the in-game menu.

Workaround: right-click hookshot.exe > Properties > Compatibility > Change high DPI
settings > Override high DPI scaling behavior: Application. After restarting the game,
fullscreen renders at full 4K and looks sharp.

Suggested fix: mark hookshot.exe as per-monitor DPI aware (in its manifest or via
SetProcessDpiAwarenessContext at startup).

System:

GPU: RTX 4070 Ti Super 16 GB
CPU: Ryzen 7 5700X3D
Monitor: 4K, Windows scaling [150%]
Hookshot release: [release name]
Windows [10/11]

Anything else

The same resolution issue here, but the workaround fix doesn't work

Same issue here, DPI settings also don't fix it, it still looks like this (3440x1440p)

Compared to the emulator

Closing: Hookshot sets per-monitor DPI awareness at start (since v2.0.0), and v2.0.6 added Output resolution up to 3840x2160 for full-size 3D at 4K. If fullscreen is still blurry on v2.0.11 with Output resolution 3840x2160 and Resolution 100%, please reopen with a screenshot and log.
