wide screen monitor can support native 1080i display resultion, many 24 '' LCD monitors are capaple of 1920 by 1200, but it is too expensive for me, I only got a 20'' one, at least can support 720p very well, most HD TV in the market only can support 720p, and transfer 1080i to 720p, any CPU better than P4 2.4 is good enough for decoding the HD signal, and a not too bad video card is also important, at least ati 9200 or above, the last one, a HDTV tuner is needed, there are many choices, ATI HDTV tuner is very famous, but I only plan to get a cheap one on Ebay.
