It’s hard to argue with “bigger is better.” In fact, for most of us, this will always hold true when choosing a new HDTV, but there are things to consider before hauling home a monster-sized set. Most importantly, you’ll want to make certain you have enough physical space to accommodate your set, which is particularly important if your new HDTV is going to be placed inside of an existing entertainment center or over a mantle or fireplace.
Check the manufacturer’s specifications for the physical dimensions of the set itself, not just the screen size. And if you plan on using the included TV stand, be sure you have space to accommodate the extra size it will add.
There is nothing more frustrating than lifting a nice beautiful HDTV up to its new home, only to have it bang against the ceiling when you try to get it high enough to rest it on the mounting hardware. If you plan on wall mounting, make sure you have plenty of clearance from the ceiling, since most wall mounts require you to lift the TV a couple of inches over the crossbar before placing it back down to rest.
