If you're in the market for a brand new Smart TV and want to learn more about which one to choose, you've come to the right place. Here is where we rank and review 2014's 7 best Smart TV as well as offering our expert buying advice that will arm you with all the knowledge you need, should you want to buy a TV that is not featured in this chart.

The first thing that you need to consider when buying a Smart TV is the screen size. The bigger you go, the more expensive the Smart TV is going to be. Also if you're buying a TV for a living room that is on the small side, the last thing your home - and your bank balance - need is a monstrous screen dominating the room (a huge proportion of TVs are returned because they're too big).
We recommend between 37in and 50in for the average UK living room, although some people would consider 50in to be too large. You will, of course, quickly get used to the size, even if upgrading from a much smaller set.
Next, consider something more technical: what sort of screen technology you want your Smart TV to have. LED is the most common in modern TVs but plasma is the other main option. Take a look at our Plasma vs LED comparison to find out more.
Ports and connections - You'll want as many HDMI inputs as possible, consider three a minimum. If you have older kit, look for Scart and component inputs. If you want to route audio from your TV to a separate amplifier and speakers, a digital connection is best, such as coaxial or optical S/PDIF. Analogue audio outputs such as phono or a headphone jack will give you only stereo - not surround sound.
Smart functions - This is a big part of modern TVs, and includes access to internet video, maybe even a web browser. Don't get carried away by gimmicks such as Facebook and Twitter integration, instead look at which video services are available. You'll usually find BBC iPlayer and YouTube, but there's rarely the full set of UK catch-up channels on offer. For that, you might want to invest in a YouView box (see BT and TalkTalk review).
It's also worth having a look at the new range of media streamers which plug directly into your TV. Google's Chromecast and the Roku Streaming stick are essentially Wi-Fi dongles that connect to your TV via an HDMI port and turn it into a Smart TV, and offer a wealth on Internet TV services. Take a look at our Chromecast vs Roku comparison review, to find out more.
3D - Many but not all TVs support 3D. There are two main types: passive and active. They both have their pros and cons. If 3D is a priority, here's an article explaining the difference between passive and active 3D.
Networking - Integral to a smart TV is a network connection. Wi-Fi is more convenient as it's one less cable to run, but less common than a wired Ethernet port.
4K - The vast majority of TVs have a Full HD resolution (don't accept fewer than 1920x1080 pixels), but the newest models have so-called 4K resolution, which offers 4x the detail of Full HD. These are expensive and there isn't much 4K content. It's also risky buying a 4K TV as it's early days and standards aren't yet finalised. You don't want to be stuck with a BetaMax or a HD DVD in a world of VHS and Blu-rays.
