It appears that the above suggestion, the Matrox MXO should work with most monitors that support a DVI connection, and can support HD resolutions (the product does seem to be Mac only, though). The Apple Cinema Display seems to be recommended because of the 59.94Hz refresh rate provides a better image quality (54.94 / 2 = 29.97). Also, the Cinema Displays are very color accurate, which many inexpensive monitors are not.
