i did a little more research and i'll bet that this is the chip....but it's just a guess.
Mstar announces MST5251A UXGA LCD TV controller
Chris Hall, DigiTimes.com, Taipei [Thursday 2 June 2005]
As a number of Taiwan companies have learned, LCD controllers are a brutally competitive segment, subject to extreme downward pressure on pricing. That isn't stopping Mstar Semiconductor from offering advanced designs, and on day one of Computex, Mstar announced its MST5251A UXGA LCD TV controller.
This LCD controller features an integrated HDMI 1.0 receiver at up to UXGA resolution and targets the North American market for digital TV. Mstar's MST5251A controller also incorporates a dual high-performance 3D motion adaptive video de-interlacer. This feature, commented company executive Kakuc Chen, enables the MST5251A to compete directly with Genesys Logic's current HDTV solution.
Cost reduction is always a design imperative for this type of controller, and the MST5251A product integrates the MstarACE-2 advanced picture/color processing engine, enabling TV manufacturers to save on the cost of a separate picture/color processing chip. Other leading features of this controller include enhanced 3D noise reduction, as well as dual high-quality non-linear scaling engines.
The MST5251A UXGA LCD TV controller is in mass production now. "We have the ability to help our customers get their TV products into mass production quickly, enabling fast time to market," emphasized Chen.
Mstar, headquartered in Hsinchu, Taiwan, is a relatively young company. Since it started out in 2002, Mstar has focused on the development of highly integrated flat-panel display ICs and mixed signal ASIC solutions.
