And also if tv can show 1080i natively it has to have 1920x1080 resolution, eventhough it's showing only 1920x540 at any given moment, So in theory It's should be able to show 1080p also?.
Whether a 1080i60 display can easily also do 1080p30 depends on the display technology. CRTs no. Plasma, LCD, DLPs yes.
Except that my CRT monitor does with a happy face.
You missed the point. Your CRT is designed to do 1080p60 (it won't be able to do 1080p30). Each scan rate your CRT supports involves significant additional cost in circuitry and calibration, especially if it needs to be big and bright for your living room. My 40" CRT at home does 1080i, but will need a redesigned deflection circuit to do 1080p.
OTOH, an LCD, plasma, or DLP display that has the resolution for 1080i can display 1080p practically for free, assuming the rest of the signal chain can accomodate 1080p.
