SS51G V2.0 barebone features SiS301MV chipset based TV-Out/DVI add-on card as an optional upgrade kit. The maximum input active resolution at PAL and NTSC system is 800x600. Because of the flexible scaling hardware, the over/under-scan (Active TV lines) modes supported by SiS301 are far beyond of these listed data below.
