I am a firm believer in the performance enhancement that a correctly installed Lumagen video processor offers to any display.  The Radiance Pro delivers staggering results into any display  but for those systems where the budget doesn’t extend  DVDO have a superb product in the iScan Mini : iScan Details here

We have seen video enhancement boxes before,  I recall the promise the Algolith Mosquito made, and latterly the Darbee Darblet but for a simple plug and play box with modest pricing the DVDO is hard to pass by.
