I'm trying to buy a LCD TV and I am confused with the different technologies advertised by the various brands which are supposed to improve the picture quality. Sony talks about their Bravia engine, Philips their Pixel Plus HD engine, etc. Do these work? Are they necessary?
Audio is my hobby and I am new to the video world. In the audio world I like to keep it simple, no processing if possible. So I am hesitant to accept a processing engine. Are TVs that do not advertise such engines worse or better?
Is it safe to buy an unknown brand like this

They don't talk about any processing engines but the specs seem to be OK and the price very good.
Thanks
Follow Ups:
LCD technology patents are largely held by Sharp and they have been one of the leaders in the flat screen technology. Sony unfortunately elected to stick with the CRT technology for a long time and were rather confident since they held 25% of the world market at one time. Their attitude is similar to Microsoft, whereby they are unwilling to pay royalties to others in order to use other patents and technologies developed elsewhere.
Sony has rushed in, and developed some key patents in LCOS technology, but Hitachi, IIRC, also has patents there also. It may interest you to know that Hitachi actually OEMed about 90% of the Japanese production of picture tubes and has recently bought out a major LCD or plasma factory.
Panasonic and Pioneer seem to have placed their R & D into the plasma technologies. Panasonic, Fujitsu, and NEC were the earliest of the plasma producers and have a significant manufacturing experience with that technology. However, while early production was somewhat limited by the military uses and their restrictions, the manufacturers producing high def sets have grown significantly. Virtually every major CRT manufacturer has dropped their models. Vizio, once primarily a computer monitor specialist is determined to claim a significant niche in the flat screen market. Sam Sung of Korea, has won a $2 billion contract from Sony to OEM Sony's LCD sets.
These days every unit is computer controlled. however, much like DD and DTS many employ identical chipsets. You will see this in the kind of optional features each set offers. Typically a lot is revealed in the number of screen size options. Typical sets offer only four options, but to have more options and the capability of zoom features require significantly more computer power.
Always check true native pixel resolution, and also double check the pixel turn on/off times or refresh rates. The highest number of pixels and the quickest times usually yield a superior picture. Also cosider service records. Philips recently had a 100% recall on every plasma set they made.
Good luck,
Stu
Akai isa well-known and much loved brand name for those who bought stereo equipment in the 70s and the 80s. Whether the Akai TV sets have any real connection to the old brand name is unclear as Akai stopped selling stereo components in the US the mid 80s until the brand resurfaced recently on TV sets.
In the great consumer magazine whose name I dare not utter, the Sony sets generally come out at the top of the heap in tests, but they are also generally more expensive too. I have a 46" Sony CRT RPTV that I think is wonderful, and I had space for the extra depth, about 24 inches.
Thanks. I believe the Akai brand has been bought. So no real connection to the old company.
Oh, and you want an engine...
