The source and the sink negotiate the resolution based on their abilities. They don't know anything about the cable. So, if both are capable of 1080p, you get 1080p. If you aren't getting sparkles or worse after that, the picture is as good as it gets.
A standard cable isn't necessarily limited to 1080i/720p. 1080p24 (BD) requires less that 1/4 the bandwidth required to certify a cable high speed. A standard cable may well have that much bandwidth or more, just not enough to be certified high speed.
