All LCDs are TFT... In the old days, there were different kinds of Color LCDs - forgot what the other one was called - but it was horrible! Mice pointers needed tails so you could find it since the refresh-rate was soooo slow. TFT added another $1000~2000 to a notebook.
Now, there are different types of LCDs today... cheap ones, good ones and professional ones. Some costs over $10,000 (USD) to properly display x-ray images for the medical field.
If you are a professional graphic artist, a cheap display will give you poor results - not enough contrast, etc... but get what you can afford. Stick to higher rated monitors. Example, Samsung sells for both home, business and professional markets... the monitor bezel may look the same - but the screen quality is different. So what looks the same at first glance costs $400, $550 and $1200 USD.
