For years, Nintendo 3DS owners have debated the differences between TN and IPS screens. Many users prefer the enhanced colors and viewing angles of an IPS screen, while others find TN screens sufficient for their gaming needs. Until now, determining which type your device has required specific conditions or even partial disassembly. However, with 3DSident, a simple and effective homebrew application, you can now check your screen type quickly and accurately.
Why Screen Type Matters
The Nintendo 3DS comes with either TN (Twisted Nematic) or IPS (In-Plane Switching) screens. Each has its advantages and disadvantages:
- IPS Screens: Better color accuracy, wider viewing angles, and improved contrast.
- TN Screens: Faster response times but inferior color reproduction and viewing angles.
Understanding your screen type can help you determine the best viewing angles for gaming, make informed purchase decisions, or confirm if your device meets your expectations after buying it second-hand.
What is 3DSident?
3DSident is a homebrew application designed to provide detailed system information about your Nintendo 3DS. It allows users to check various hardware details, including system model, battery health, and, most importantly, screen type. With its latest updates, 3DSident now includes a dedicated function to identify whether your device uses TN or IPS screens.

How to Use 3DSident to Check Your Screen Type
The process of determining your screen type using 3DSident is straightforward. Follow these steps to get accurate results:
Step 1: Install 3DSident
- Ensure you have a homebrew-enabled 3DS system.
- Download the latest version of 3DSident from a reputable source, such as GitHub or a trusted homebrew repository.
- Copy the application files to your SD card, inside the “3ds” folder.
Step 2: Run 3DSident
- Launch the Homebrew Menu on your 3DS.
- Select 3DSident from the menu and wait for the application to load.
Step 3: Check Your Screen Type
- Navigate through 3DSident’s system information until you find the screen type data.
- The application will display whether your top and bottom screens are IPS or TN.
Advantages of Using 3DSident
Before 3DSident supported screen detection, users had to rely on visual tests, which could be subjective and unreliable. Some even resorted to opening their devices to inspect the screen hardware directly. 3DSident eliminates this guesswork by providing an objective method for checking screen types.
Here are the key advantages of using 3DSident:
- Accuracy: The application retrieves screen type data directly from the system firmware.
- Ease of Use: No technical knowledge or manual color comparison tests required.
- Non-Invasive: No need to disassemble your console or risk damaging it.

What to Do Once You Know Your Screen Type
After identifying your screen type, you can make more informed decisions about how to use and maintain your 3DS:
- If you have IPS screens: You may want to take advantage of the enhanced colors and brightness by adjusting your settings for optimal display.
- If you have TN screens: Consider using straight-on viewing angles for the best visual clarity.
- Buying a second-hand 3DS? Sellers can now verify screen types using 3DSident, ensuring buyers know exactly what they’re getting.
Conclusion
The ability to check your Nintendo 3DS’s screen type with 3DSident is a major breakthrough for gamers and collectors alike. This tool not only provides an easy and non-invasive method to determine whether your system has TN or IPS displays but also helps make informed purchasing and gaming decisions. If you own a homebrew-enabled 3DS, installing 3DSident is a simple yet valuable step towards better understanding your handheld device.
