The GBS is suffering from poor upscaling plain and simple. The more expensive units usually don't suffer that moire effect on desktop backgrounds. Heck, the TVs upscaler is doing a better job with the direct SCART RGB input. Amazing considering how cheap the upscalers usually are in TVs. The difference in quality between S-Video and SCART RGB would be more obvious if it was a CRT as it is usually noticeably sharper, with zero color bleed and much purer color rendition. The LCD's scaling is softening the picture quite a bit.
