Q. Help, she's an accountant and I have big big problems!
Answer
You do it like this: "Dear, I was all set to buy a TV with a 240 hz refresh rate and a 4 meg dynamic contrast ratio for $3000, but then one of those experts on Yahoo Answers explained that the human eye can't tell the difference between 120 hz and 240 hz. Also, he said that advertised dynamic contrast ratios are mostly marketing exaggerations that have little meaning. So instead, I've decided to buy this much cheaper 120 hz set but with an even bigger 52 inch screen for only $2000. Since I've saved us a thousand bucks, here's your half. Have fun shopping, and I'll meet you at Costco."

Is an LED screen better than an LCD screen if the tvs have the same contrast ratio?
Q. Is an LED screen still better than an LCD screen in terms of colour contrast if the tvs have the same contrast ratio? Or does it make little difference, as I suspect? :) This would be really helpful as I am thinking of buying a new tv, thanks.
Answer
"LCD" and "LED" sets have the same screen, an array of liquid crystals. The difference between the two is the backlight, not the screen. Old LCD sets use a fluorescent lamp. Newer "LED" sets use a bank of light emitting diodes.
Forget contrast ratio in TV advertising claims. It's impossible to measure dynamic contrast ratio, so manufacturers can claim anything they want. The best way to judge contrast is to look at different sets operating as demonstrators in a TV store. Being "LED" doesn't automatically guarantee better contrast. You have to evaluate specific models, and there are some conventional LCDs that do better in professional lab testing than several "LED" sets.
