I am looking to get a new HDTV and would like to connect my 24" iMac to it because u can never get enough screen space anyways, I was just wondering if I would be able to get that right resolution for the TV, Sony HDTV
Even though the screen is larger, it has less pixels than your 24" iMac.
iMac = 1920x1200 | Sony = 1366 x 768
Try to find an HDTV with Full HD support which 1920x1080. They also make 26" monitors with the 1920x1200 resolution and then get an Elgato EyeTV for the TV tuner. Will usually be cheaper going that way too .
