i wanna go ahead n get 50000:1 n i prefer if i get 2ms response time as compared to 5ms.... also i prefer 23" to a 21.5"

now what i am asking is if this 50000:1 n 2ms makes a lot of difference as compared to the other .... and what about the size difference ? does that also make a high difference ?

the other main thing is the hdmi... 2buy or not 2buy is the question..
i dont even know whats the main purpose of it ...
i dont have a ps. i have xboz n wii at home but they are not mine.

my purpose of getting monitor is for my new pc... so is hdmi necessary cuz as far as i know pc connects to the normal old fashion slot.
unless ofcourse i can connect to pc using an hdmi cable and it really makes a diference to the video quality

also which company... aoc, acer, lg, samsung..... if there is one that i should not buy cuz its a bad company then let me know

thanks
