While Westinghouse positions itself as a budget brand, it has shown it's also willing to experiment with cutting-edge technology. The 55-inch is the company's first TV to feature a 4k resolution, and is planned to be released in the first quarter of 2013.
The TV features a Quad HD resolution, which is essentially a consumer version of 4K, and measures at 3,840x2,160 pixels (or four times 1080p).
Interestingly, 3M researcher Dave Lamb recently told CNET that 4K would only have benefits in sizes above 55 inches. Based on a brief demo of mainly static images in an unknown resolution it was difficult to see whether the TV was producing additional detail at a normal seating distance.
The company had the prototype on display at CE Week in New York, and while specifications and pricing are not yet finalized, Westinghouse says it's going to be "affordable."
While Toshiba's 55X3 television was due to be the first 4K released in the U.S. market, the company has told CNET the TV will also slip to 2013.
While cinemas routinely screen movies in 4K resolution, the format has yet to hit the consumer market. There are rumors that Sony is planning to release the Spider-Man reboot on a 4K version of Blu-ray.
