Since you have not mentioned your exact requirements in terms of size or other features let me point out a few key aspects you need to take care of. Hopefully, it will help you decide on a suitable model -
This Is of utmost concern when buying a television. Please note that there is a particular distance between you and the TV for comfortable viewing experience. Always buy a TV that suits your room. The ideal.distance is 4 to 8 feet for a 32 inch LED while it should be 5 to 10 feet for a 40 inch TV.
Resolution refers to the clarity of the picture on your TV screen. It is measured in pixels. More pixels mean more clarity and more graphical details. In India, we have four kinds of resolutions - Standard definition, HD ready, Full HD and Ultra HD. The pixels increase in that order. However, please note that beyond a certain distance the resolution does not make any difference to a naked eye. The difference goes clear as you move closer to the screen. Well, you don't go so close to your TV, right? So I would recommend to opt for one that really suits you. Do not go buy ads, or the technical jargon.
3. Refresh Rate
As we are aware, a video is a collection of numerous images. They are displayed at a higher rate so that we get a moving visuals. Refresh rate is the speed at which these images are updated on a per second basis. If refresh rate is better, you get better video quality.
It depends on what type of content you are interested in. If you need high action visuals like sports or racing, you should go for a TV with higher refresh rate. If your favourite genre is regular stuff like movies and daily soaps, a standard refresh rate of 50Hz would be enough. Also note that refresh cannot be more than 200 Hz in a practical world, but manufacturers tend to advertise it in a exaggerated manner. It would be advisable not to fall prey for such tactics.
4. Audio quality
The RMS power rating indicates the sound volume of your television. Please note that a high rated RMS may not necessarily mean a better sound quality. Instead of going by the advertised RMS values, it is better to check it personally at different volume levels.
Panels play an important role in deciding the viewing angles. The IPS panels have better viewing angles. It means your viewing is distracted no matter at which angle you are sitting. VA panels have restricted viewing angles. You won't have much freedom. If you have a larger room, I would recommend you to opt for a IPS panel. More over, IPS panel is more stronger and durable than VA panels.
This is a new concept in television technology. When you are watching a low resolution video on a larger screen, the picture engine ensures that the video is not blurred or pixellated.
Live....and Let Live!
