Sorry to burst your bubble but "HD Ready" TV's are not capable of displaying any signal in HD. This "branding" only means that it will accept a HD signal and then render it as SD (or occasionally at a slightly higher resolution that is still less than HD).
The "HD Ready" stickers were another con designed to prevent a drop in the sales of SD sets once the true HD sets started arriving.
Of course I can't sue anyone for misleading me, because I new the full facts before I bought my HD Ready TV.. I just didn't care, all I wanted was a cheap and massive LCD for the bedroom that could accept a signal from a HD tuner set top box (which allows me to use HD features like EPG)
