A PS2 to HDMI converter is a device that allows you to connect your PlayStation 2 console to a modern TV or monitor that only has HDMI inputs. PS2 to HDMI converters are relatively inexpensive and easy to use, and they can significantly improve the quality of your PS2 games.
PS2 to HDMI converters work by converting the analog video and audio signals from your PS2 console into digital signals that can be sent over an HDMI cable. This allows you to connect your PS2 to a TV or monitor that does not have any analog inputs, such as a newer HDTV or 4K TV. PS2 to HDMI converters also typically include a scaling feature that can improve the image quality of your PS2 games, making them look sharper and more detailed.
