If you play Persona 5: The Phantom X on an ultrawide monitor, you might have noticed annoying black bars, a squished HUD, or resolutions the game just won’t show. Although the title sort-of works at 21:9, larger panels like 32:9 are still an afterthought—and even plain ultrawide support feels unfinished. The good news is that there are easy tweaks, from lightweight tools to deeper mods, which can clean up the picture.

Confirmed Fix for Ultrawide Issue in Persona 5 Phantom X

While there are many things you can try, just like with previous Persona games. There is a confirmed fix for the Ultrawide issue for Persona 5 Phantom X. What you need is the Borderless Gaming Tool. It is available to download from GITHUB.

Here is a step by step:

  • From the Github page download the BorderlessGaming9.5.6_admin_setup.exe.
  • Install the Borderless Gaming Tool.
  • Launch Persona 5 Phantom X and from the Display Settings switch to Windowed Mode.
  • Minimize the game and open Borderless Gaming Tool from the taskbar.
  • Select Persona 5 Phantom X in the Borderless Gaming Tool and add it to your favorites too.
  • Right-click on the game and check “Full-screen” and “Auto-Maximize.”

If you followed the steps correctly, the Borderless Gaming Tool will adjust the game to your Ultrawide screen. This trick shines on 21:9 screens and avoids any mods or file changes. That said, it won’t fix scaling issues or stretch the UI across 32:9 displays.

Alternate Fix

If you don’t want to download any software to fix your problems, then you need to tweak the game’s config files. Adjusting the config lets Persona 5: The Phantom X run at setups like 3440×1440 or 5120×1440.

How to Do It:

  1. Find the config file. Its is usually in the game folder or under AppData and Saved Games.
  2. Open it with a simple editor like Notepad.
  3. Scan for lines named ResolutionX, ResolutionY, or AspectRatio.
  4. Change them to your screen’s numbers (for a 32:9 set 5120×1440).
  5. Save the file and restart the game.

This works for many, yet some say their settings vanish or black bars linger, especially on 32:9 screens.
