How to Fix Wo Long Screen resolution bug

Fortunately, there are several solutions to this issue that players can try to fix the Wo Long screen resolution bug. One of the first things to try is disabling any other display driver in Device Manager aside from your GPU. This can help to prevent any conflicts between drivers and may allow you to change the screen resolution as desired.

Adjust DPI Settings

Another solution that has worked for many players is to adjust the high DPI scaling settings for the game. To do this, players should go to the game.exe and right-click, go to properties, and then click on the compatibility tab. Then, at the bottom of the window, select “change high DPI settings” and click “override high DPI scaling behavior.” Set it to application and press OK and then Apply in the previous window. This should help the game to communicate properly with Windows scaling on your desktop and allow you to change the screen resolution.


Another workaround for the Wo Long screen resolution bug is to use DLSS (Deep Learning Super Sampling) quality mode. This mode is essentially the same as rendering at 1440p, but it will still look better than actually changing the internal resolution to 1440p. If you’re determined to make the game run at 1440p, you could try setting your monitor’s resolution to 1440p before you launch the game. This may trick the game into running at 1440p instead of 4k, but the quality may suffer.

Try turning off Control Flow Guard

Try turning off Control Flow Guard for the Hogwarts Legacy.exe file. Control Flow Guard is a security feature in Windows that can sometimes cause issues with games. Disabling it may help to improve the game’s performance and prevent issues like the screen resolution bug.

Turn off Vsync

Another option is to turn off Vsync in the game, but force it on in the GPU control panel instead. This can help to prevent screen tearing and other visual artifacts, while also improving performance.


Use FSR (FidelityFX Super Resolution) instead of DLSS. FSR is another technology that uses advanced algorithms to improve the quality of graphics in games, and it may work better than DLSS in some cases.

Run in Windowed mode

Try running the game in windowed mode instead of full screen. This can sometimes help to prevent issues with screen resolution and other display-related problems.

By trying these solutions, players can get back to enjoying the immersive and exciting world of Wo Long Fallen Dynasty without any pesky screen resolution bugs getting in the way.
