I was wondering if anyone has heard anything about this device, or used it. http://www.ati.com/shopati/promotions/hdtv.html My question is...my TV supports either 480p, or 1080i. What monitor resolution would this be comparable to? I would love to have my computer running off my HDTV, but if is not going to look as good as it would on a monitor it may not be worth it. Thanks in advance for any advice.
