Recommendations for new bigscreen TV

A lot of the times there is enhancement circuitry used to make the picture look brighter and sharper, specially in the stores. A brighter picture will attract your attention. But it is not necessarily a good picture. In most cases, shadow detail and color accuracy are compromised. You don't realize this until you see a properly calibrated set. Look at the Sony WEGA sets for example. My first impression was WOW! But then, upon close inspection, there is so much edge enhancement that the picture looks unnatural to my eyes. This is with their factory settings. Once you adjust the set all the detail you thought you were seeing (read: noise) is gone. This is not to say that the picture is not excellent, it is. It is just not as crisp as you thought it was or expected it to be. One thing they do in Hitachi sets, as they do with other sets to one extent or another, is push blue to get a brighter picture. They then push red at the color decoder level to compensate. Sometimes they do the same with green, but not as often. When you bring the settings back to standard, the errors (push) at the color decoder level are more noticeable. This is what people refer to when they speak of color decoder accuracy. You end up with pinkish reds as opposed to solid reds. This is because the only way to remove some of the red push is to reduce the color adjustment to compensate. This will cause a decrease in overall color purity. The Toshiba TP50H95 & TP50H60 sets are the same accept for the following differences that I have noticed: - TP50H95 has a protective screen (screen saver). These are the only differences I can see from the specs. So, unless you want the screen saver and gold plated component inputs, I would not spend the extra money. Another set I would look at is the Sony KP-53V75. It has a 3D-Y/C digital comb filter that will enhance picture quality with composite sources such as cable. This is a better implementation than the digital comb filter the two Toshiba sets above use. Will the Toshiba look as good as the Hitachi? Well, this depends on what your definition of good is. Right out of the box, it will probably not look as good. After calibration? Absolutely. One thing about Toshiba sets is that they do need some work to get the best results. Optical and Electrical Focus is something that will enhance the picture on most Toshiba RPTV sets. If you are planning to do some of the work yourself, the Toshiba is friendlier to maintain. The Sony set is more difficult to converge as it uses an implementation called Dynamic Convergence. Toshiba sets use Digital Point Convergence at the service level. So, chances are that you'll be able to get better convergence results from the Toshiba than from the Sony. Note that my comments on convergence are considering that you may want to do the work. If you are planning to get the set calibrated by a professional, and have access to a good calibrator that will perform the full work, I would suggest you go with the Sony. Is calibration something you could do yourself? Sure, anyone is able to calibrate a set. Short of the color analyzer-assisted gray scale adjustments, everything else can be done by you with a little patience. If you are not comfortable fiddling around your set, I would recommend you get someone who's already experienced, specially with your particular set. You'll end up with a great picture without the aggravation. Hope this answers all your questions. Regards, Leo
