HDMI vs DVI?

Bear with me, I might not explain this very well

Ive been looking at HD LCD TVs. They come with a HDMI input and a DVI.

However if I plug my cpu into the DVI port the TV has a max res of eg 1300 ish.
If I use the HDMI I can do 1080i, which has a res of 1920x1080

am I understanding this right? Is this the only differnce of using a DVI input?

Apart from the fact that im speaking hyperthetically, Im looking at buying an LCD tv which will be fine near my CPU

Realy, I new I was doing something wrong :eek:

Sorry by CPU I was refering to computer, bad habit.

Can any one confirm the above for me or put me right If im not understanding it

My cards a x1800xt so I have both 2xDVIs and a HDMI. Its more the TV thats my problem. Some say they are HDTVs but dont have a HDMI input. Can I still do 1080i (or P which ever it is) if it only has a DVI input?
Also they state a max res of 1330 ( something like that) however they say they can do 1080i but to my understanding this is 1920 res. Im just a little confused

I dont have an LCD TV at all, Im trying to understand what im buying before I get it. If you look up the spec of HDTV it has a 1920x1080 res. Therefore any TV rated as 1080i can do a res of 1920x1080. My question is can I do 1080i thought a DVI input or do I have to use a HDMI input?

Not to sure exactly what 1:1 VGA mapping is but I will google it and have a read when I get home. Will this give image quality as good as 1080i. Realy this is my only issue as I intend everything to run though my HTPC ( this is already build, just need the TV to go with it : / ) so inputs to the TV aint too important to me at the expense of image quality.
