at the size panels you are looking at, i would only recommend 1080p if you are going to hook up a computer to the TV...

Else for a 32" HD-Ready is plenty enough unless u plan your viewing at <2 foot distances.

Was previously a happy user of a 32" Sony V-Series Bravia (HD Ready)

Am currently using a 37" Sharp Aqous (Full-HD) and have a PS3/PC/DVico/DVD/Astro hooked up (all via an Onkyo Receiver)

FYI my TV is the Sharp Aqous LC37A65M

i believe its the predecessor to the 66...

i got it for <3500 around December if i'm not mistaken...
I'm happy with it...

Congratulations!
Take some pics to show us

yes that is correct

assuming your gfx card has DVI and no HDMI output...
you need to buy a cable that has DVI->HDMI (or a HDMI cable and a HDMI/DVI converter for one end)...

u wont be sorry. VGA images look like ass compared to DVI/HDMI connections

the advantage of having hdmi is that you can stream video and audio as well in one single cable. if u plan to have the hdmi connected to the TV just for display purposes and want to have the sound via something else (speakers or a amp/reciever) then u are fine just using a DVI->HDMI cable.

my current set up:
PC->TV (Graphics Card, DVI-to-HDMI cable)
PC->Receiver (Sound Card, RCA or Optical cable)
