Just sharing a post I made about choosing a TV:
1 - have a budget, and use this link to see what are the actual prices others have paid:
Then see the stickies in Hardwarezone, on LCD vs Plasma Vs LED for the pros and cons of each technology.
Places to buy:
Other useful info are kept here:
Remember, you need to filter through all the marketing noise and the sales talk, then understand what type of stuff you watch:
SD = standard definition like free to air TV, or DVDs
HD = high definition, like Blu Ray
Then see which are the popular models and choose from there based on your budget.
I personally prefer plasmas for their picture quality and energy consumption is secondary to PQ.
I seldom watch TV, and the lowest quality I go is for DVDs for old movies, but Blu Ray discs form the majority of my viewing diet.
I have no financial interest or other interests in any of the items / events I write about.
