Unless you have tons of money to spend on a HDTV, buying a HDTV can be a daunting task. There are so many models, so many brands, so many specs, and so many opinions to confuse you. The easy way out of this is to pick up a HDTV from the brand you trust and enjoy it but then you would not know whether you made the best use of the resources available to you. You could have got a better TV for the price you paid for your favorite brand’s TV!
The first question that usually comes up is whether to go for a plasma or a LCD. The answer to this question depends upon what do you watch the most and where do you keep your TV. If you are watching movies and sports a lot then you should go for a plasma. If you are more into playing games [PS3, Xbox, Wii] for long periods and doubling the TV as a PC monitor then LCD is the way to go. Plasmas are said to work better in a darker room environment, while LCDs in brighter but the latest plasmas come with anti-glare screens.
Plasmas are known for producing better blacks and having greater true contrast ratios. There is no or little motion blur when watching fast moving action. On the other hand, plasmas have burn-in issues. Burn in occurs when the logo of a TV channel for example stays on even when you change the channel, which is the reason why gamers go for LCD. The latest models have anti-burn in technology built into the TVs so burn-in is not a factor that it used to be a few years ago. If your budget is decent then you can’t go wrong with picking up a mid-range or up plasma from Panasonic or Pioneer.
LCDs have no burn in issues but suffer from motion blur, which is why LCD manufacturers have come up with 120HZ models which reduce, if not eliminate, the motion blur. If I am no wrong, 120HZ is useful only when images move horizontally and not when images move vertically or diagonally. The LCD technology that various manufacturers use also differs, for example LG uses S-IPS, Samsung/Sony use S-PVA and Sharp uses ASV. Each technology has its own pros and cons, so you may want to pick the one that suits your needs. Since different manufacturers use different technologies, don’t read too much into ‘dynamic contrast ratio’ when comparing models of different brands. Also note that the panels used on screen sizes less than 40 inches may be out sourced from companies in China or Taiwan by the manufacturer. Again any high-end model from any major manufacturer should do the job well.
Other question that comes up is whether to go for a model with 720p or 1080p. Right now the major source of 1080p is the blue-ray, i.e. blue-ray players and Sony PS3. So if you plan on playing a lot of PS3 games and watching a lot of blue-ray discs, 1080p is the way to go. On the other hand, if the majority of your programs are standard definition, DVDs, 720p broadcast from HD TV channels then 720p should be fine. It is said that it is difficult to see the difference between 720p and 1080p on TVs with screen size smaller than 42 inches and you need a 46 inches or more screen size to truly appreciate 1080p. In short, 1080p could just be another specs on screens that are less than 42 inches, so if you are taking anything less than 42 inches, a HDTV with 720p should be fine.
The question of LCD or plasma also depends upon your budget. If your budget is $1000 or less, I would recommend a LCD. Many entry-level plasma models could have a native resolution of less than 720p, which makes them enhanced definition TVs [EDTVs] and not HDTVs. I am not sure about how good the anti-burn in technology is on the entry level plasmas.
Recommended models:
Plasmas: Panasonic plasma Z80 and up, Pioneer plasmas
LCDs: Samsung 6 series and up, Sony W series and up, Sharp Aquos, LG Scarlet, LG 60 series and up
On budget: Sony V series, LG G50 series, LG G30 series
My HDTV: LG 37LG30
Pros : Price [got a good deal on it], S-IPS ‘LG’ panel, 720p [I didn't want to pay for 1080p on a 37 inch model], 3 HDMI ports, 5 ms response time, Sharp picture, lots of calibration options
Cons: Sometimes you hear a humming sound from TV speakers but it is not an issue if you use a home theater system …. I guess that LG’s onboard invisible speaker system is still better than the onboard speakers of some of the other manufacturers
Would I recommend it: Yes …. Highly recommended
Happy HDTV shopping!!
