This provides higher image quality because it converts from RGB signals, unlike typical composite signal to HDMI converters. Please check the comparison images I've uploaded. For RGB input, please use a SCART cable. *RGB 21-pin to SCART conversion cables are also available. This is an upscan converter device that converts analog RGB to HDMI signals. The RGB terminal supports SCART terminals. SCART RGB cables are cheaper to obtain than RGB 21-pin cables, making them a good value. Wide screen 16:9 and 4:3 square screen switching is possible. You can select 16:9 or 4:3 resolutions from multiple presets using the 720p/1080p button. Instruction manual and AC adapter included.
