Smart TVs offer much more than just a good screen and display resolution
Buying a television is like welcoming a brand new member to the house. Over the years, the beloved enter tainment box has evolved to actually become connected and smart. Keeping that in mind, we look into the essential features to help you choose the best TV within ₹30,000.
Essential features
We all are familiar with TV jargon like display, audio and ports. Added to them now are ‘smart’ features like connectivity and Internet access. Rohan Agarwal, vice president-consumer electronics business, Micromax Informatics, comments, “Technical parameters that speak about the quality of a smart TV are mainly its panel and internal components. The processing setup of the television should be stable and not crash while installing apps.”
Arjuun Bajaj, director, Daiwa TV, explains, “Key technical specifications worth paying attention to include screen size, RAM and ROM, panel grade and brightness, speakers (to give the surround sound) and, most importantly, connectivity. These are the prerequisites to a smart TV experience.”
Let us now explore these features for a smart TV in detail.
Refresh rate, contrast ratio and resolution. Simply put, refresh rate is the pace at which the TV screen changes images without any motion blur. Technically, it is the number of frames the TV can display every second and is represented in Hertz (Hz). A refresh rate of 120Hz or higher is the optimal specification. A 120Hz refresh rate means the TV can show 120 images per second.
Contrast of the TV is the ratio of the brightest (white) image produced to the darkest (black) image. There is no proper standard for comparison of contrast ratio as the ratio evaluation process differs from manufacturer to manufacturer. However, a contrast ratio of 3000:1 is advised. Lower contrast ratio results in lower colour clarity or whitewash effect.
