How to Full Screen on AetherSX2 and Fill Your Entire Phone Display
Playing PS2 games on your phone feels amazing, but those blank screens on the corner of the mobile can ruin the whole gaming experience. You can easily fix this issue in less than a minute. We will go through every step to fix this.
The main problem is the aspect ratio. PS2 was originally built for an old TV screen with a 4:3 aspect ratio. Modern phones use a wider 16:9 or even taller screen. This mismatch is why you see the empty black space while gaming.
Why AetherSX2 Shows Black Bars by Default
When you play the game for the first time in AetherSX2. The screen shows black bars on both sides. This happens because the emulator starts with the original PS2 aspect ratio, 4:3, to keep the game as its original size. Your device screen size is much wider, so the leftover screen becomes black.
This is not a bug issue. It’s the emulator’s default screen size locked in. But if you want to change the screen size. You just need to change the one single setting in the AetherSX2. This is not a bug issue. It’s the emulator’s default screen size locked in, and adjusting a few display options along with the best settings for NetherSX2 can help improve overall gameplay experience.

Which Aspect Ratio Option Should You Pick?
AetherSX2 gives you a few choices to select any aspect ratio you want from the menu. Here is what each aspect ratio means.

16:9
It is the best choice for most modern mobile devices. It fills the screen properly, and most games still look good in this size ratio. A small part of the left and right edges may show black bars, but the gameplay is not affected by it.
Stretch to Fill
This screen size setting forces the game image to cover every pixel of your screen. Some games are a bit wide or distorted. It helps to remove all black space completely.
Fit to Screen
This keeps the game image as large as possible without affecting the gameplay. Some thin black lines may show depending on the screen size. But the image stays undistorted.
How to Enable Widescreen Patches for Better Results
Some PS2 games were not originally designed for widescreen displays. When you stretch them, the game image looks distorted, and in some cases it may even affect performance, which can be improved using these AetherSX2 lag fix tips.
Go to the App Settings, then scroll down to find Enable Widescreen Patches and turn it on. This applies to supported games. This makes the game fill the screen properly. Not every game supports this patch. The most popular games like God of War, Need for Speed, and Tekken support this patch.
If you ever notice that the game is looking good at 16:9, you don’t need to turn on the widescreen patch.
Fixing Full Screen on Phones with a Notch or Punch-Hole Camera
Modern mobiles have a camera cutout at the top of the screen; some have a small camera hole or notch. This can block the game image when switching to the full-screen view.
To fix this issue, go to your mobile’s main settings. Look for the Display or Full Screen Apps option. Find the AetherSX2 in the list and enable the full-screen or cutout display option for it. The name could vary by mobile brands, but it is usually under Display Settings or App Management.
If you have a Samsung phone. Look for a Full Screen App under Display Settings. On a Xiaomi or Redmi phone, check the App Full-Screen option under Display Settings. After enabling this option, launch AetherSX2 again. Now the game will fill the whole screen, even past the camera area.
