Types of televisions

When shopping for a television, one of the first decisions you will have to make is which type of TV you want to buy. OnBuy offers a variety of different types of TVs, including OLED and QLED.

Not sure what the difference is? Check out this post covering the benefits and differences between OLED and QLED TVs.


LED televisions use LED backlights instead of fluorescent backlights. They offer improved picture quality, better energy efficiency and a slimmer profile.


OLED televisions are one of the newer types of televisions and use organic light-emitting diodes to produce images. They offer the best picture quality of any type of television and have excellent viewing angles.

The downside of OLED televisions is that they can be expensive and have shorter lifespans than other types of televisions.


QLED TVs are the latest in television technology. They are made with a quantum dot light emitting diode (QLED) display, which produces brighter and more accurate colours than traditional LCD displays.

These TVs use a combination of advanced algorithms, nanotechnology, and quantum dots to achieve superior picture quality. They're also able to produce a wider colour gamut, allowing for more vivid colours and better contrast.

Features to consider

Once you have decided which type of television is best for you, there are a few features that should be considered before making a purchase.


The size of your TV should be one of the first things you consider when making your purchase. If you’re looking for a smaller TV for a bedroom or office, a 32" screen should suffice.

If you’re looking for a larger screen for your living room, a 55" TV should be more than enough. If you’re looking for an even larger screen for a home theatre, you may want to consider a 65" or larger TV.


The resolution of your TV is also something to consider. Standard definition TVs have a resolution of 720p, which is fine for basic TV viewing. If you’re looking for a higher-quality picture, you’ll want to look for a TV with a 1080p or 4K Ultra HD resolution. HD offers a sharper picture with more detail, while 4K Ultra HD offers four times the resolution of standard HD.

The number of ports and connections your TV has is another important factor to consider. Most TVs have at least three HDMI ports, which allow you to connect devices such as Blu-ray players, game consoles, and streaming devices.

Other connections to look for include component, composite, USB, and ethernet ports. If you plan on connecting multiple devices, make sure the TV has enough ports to accommodate all of them.

Smart features

If you’re looking for a smart TV, there are several features to consider. Most smart TVs come with a range of apps and services such as Netflix, Disney+, and Amazon Prime Video. Some TVs may also come with voice control capabilities, allowing you to search for content using your voice.

Other features to look for include a web browser, the ability to stream content from your mobile device, and the ability to mirror your laptop or tablet screen on the TV. Want to know more before you buy? Check out this essential guide to smart TVs.


Finally, the price of the television should also be taken into consideration. It is important to find a television that fits your budget and offers good value for money.
