Buyers can choose from various options when looking for brand-new HD TV sets. As HD TVs can be expensive, it is important to consider multiple aspects before buying one. Also, today's TV sets are equipped with advanced technology and offer many customization options. This makes it important to pick the most suitable television that meets all your requirements. So, here are the 6 things you need to consider when getting a new HD TV: Screen resolution This is definitely one of the top things you need to know when getting a new HD TV. Many manufacturers give buyers the option to choose from the latest configurations, like 4K TVs containing 3840x2160 pixels and 8K TVs with a resolution of 7680x4320 pixels. The ultra HD or 4K option offers great signal, sharp picture quality, and greater clarity for even the most miniature objects on the screen. Many films and other visual content are produced in 4K nowadays, making your viewing experience richer. While 8K TVs provide even better picture and video quality, there are very few 8K movies you can buy. So, while 8K TVs will be a good option in the future, you should consider going for HD, Ultra HD, or 4K sets. Aspect ratio and screen size HD TVs use a widescreen 16:9 aspect ratio (screen width to height). Standard-definition TVs come with a square-like 4:3 aspect ratio. Widescreen HD TVs have a slightly lower diagonal measurement, so a 27-inch HD TV will not seem as tall as a more square-like 27-inch TV. So, standard-definition TV users looking to upgrade to an HD TV with a screen matching the height of their current device should go for larger HD TVs. So, users looking for an HD television with a screen height equivalent to their current 27-inch standard-definition TV can choose 32-inch HD TVs. Refresh rate Refresh rate describes how many times per second a picture is refreshed on the screen. Usually, refresh rates of 60 or 120 Hz are considered reasonable. The 120 Hz option is better as the higher rates provide more fluid picture quality. HDMI and connections HDTVs with at least 4 or more HDMI ports offer better connectivity with other devices. While buying, you need to ensure that the ports come in the newer HDMI 2.1 format. Presets Many HD TVs have preset picture modes to control key settings—contrast, brightness, tint, and more. TVs with several preset options to create custom presets are preferable. Energy consumption Energy consumption is another one of the key things you need to know while buying an HD TV. LCD HDTVs consume less power than plasma sets. However, LED-backlit LCDs are even more energy efficient. So, factor in the energy consumption to save on electricity costs.
