Thank you tylerSC, Josh128 and KOF for suggestions . It's a big help for me knowing that I have many options to consider.
Today I had an opportunity to demo a 43F4900 in a store. Best thing is, the plasma is facing the wall not windows. I asked the salesman to play the movie on my flash drive via USB. The first is my favorite TV show Amazing Race. Wow, I can see that the colors are close to the real thing and also close to the colors of my CRT. The blues are blues, the reds are reds, and that is simply out of the display unit, which I think the settings are never calibrated. My eyes were hooked on the TV. I was sitting around 4 to 5 feet from the TV. Then, after 10 minutes, I told the salesman to play a cartoon movie called "Up". Up is one my favorites. Wow again! The colors are simply colors. I'm amazed. Take note of my experience is, 20 years of 21" CRT Color TV, which we still use until now. Plus, my favorite IBM 17" CRT monitor which I connect with TV Tuner. This IBM 17" CRT has the most accurate colors of the TVs I've seen. The blues are blues, the greens are greens. I came into conclusion that the bigger screen of my 17" IBM CRT Monitor is the 43" Samsung F4900. It's as if my CRT monitor was made into giant screen. I was really hooked on the picture.
To make simply an analysis in a different level, for me a LED TV says "Hey, I'm here, watch me now!". Plasma TV says to me, "Hey, I'm here, I'll care for you, I'll make a lullaby to you". Plasma is very motherly and sweet while LED is a communist commander. LED has very imposing colors to my eyes while plasma has very gentle, fulfilling colors to my eyes. These statements are my only ideas. I'm sorry if I bit descriptive with my statements. Since I'm a headphile, may I compare the LED TV to a Grado SR60 Headphone, music is a bit shouting and forward on my ears and the Plasma TV is a Sennheiser HD600 which has a laidback sound, sweet and lullaby.
Let's go back.
Our TV consumers here in our place are not plasma buyers, most of them are LED buyers. Even the salesmen here, most of them suggests LED for the reason that it consumes lesser power and its the most hi-tech and latest. The salesman are not concerned about picture quality. However, there are few salesmen which said to me: "That plasma will give you a CRT picture quality", "That plasma sample movie that you have seen here in our store will be the same quality when you bring that TV in your home." I think what is needed by TV appliance stores is a dedicated TV room where lighting can be emulated from a home a lighting, and where lights can be controlled, bright to dark and vice-versa, more like to an audio room in when buying quality speakers for our home.
Guys, I will go for 43F4900. Thanks for your help.
One more please, should I also opt for 51"?
I will first use the TV in my bedroom. The maximum viewing feet is 10 to 12 feet. I think 43" will be more satisfying for me. I have read from CNET, "Get the biggest screen you can afford." Will this work also for my situation? One more help please. I owe a lot to you guys now. Anyways, I am enjoying a lot on this forum because I am learning, I am a student again. Soon, I'll become a videophile.
