There are various categories of HDMI adapters. By connecting your PS2 directly to the TV, some devices enable plug-and-play functionality. Products that cost more and are more specialized, like the Kaico OSSC, have RGB rather than composite inputs (SCART). Don't worry; you can easily purchase a PS2 SCART or component cable. This cable lets you link your PS2 to the scaler, sending HDMI signals to your TV.
