Operating Instructions
Aspect Ratio Switching:
The adapter features a switch to toggle between 4:3 and 16:9 aspect ratios. This allows you to choose the display mode that best suits your preference or the original game's intended aspect ratio.
- 4:3 Aspect Ratio: This is the original aspect ratio for most retro consoles. It will display the game with black bars on the sides of a widescreen TV, preserving the original geometry.
- 16:9 Aspect Ratio: This mode stretches the 4:3 image to fill a widescreen TV. While it fills the screen, it may distort the image.
To change the aspect ratio, locate the small switch on the side of the adapter and slide it to your desired setting (4:3 or 16:9). You may need to briefly power cycle your console or switch inputs on your TV for the change to take effect.
