TV Buying Guide: Everything You Need to Look for In Your Next TV 

TV Types and Display Technologies 

Confused between Q LED vs OLED or unsure between 4K vs QLED TVs? You won’t be for long. Before we dive into this TV buying guide, let’s first explore the most common TV types and display technologies to help you navigate the diverse TV market. 

Determine the Purpose of Getting the TV  

Next, it’s important to assess your needs and determine how to choose a TV that best suits your lifestyle, whether it’s for entertainment, sports, or gaming. Understanding your primary use will help you choose a TV with the right features while ensuring you get the best value for your budget. 

Here’s what to look for when choosing a TV for your specific purpose

10 Essential Things to Check/Look for When Buying a TV 

You’ve figured out what you’ll be using your TV for, and you know the difference between OLED and QLED. Now it’s time to dig into the details that will truly make or break your viewing experience. This section of our TV buying guide/TV purchase guide will walk you through the essential things to check before buying a TV, ensuring you get the best performance and value for your money, whether you're eyeing the best 4K TVs or the top rated smart TVs. 

Screen Size 

When buying a TV, screen size is one of the most crucial factors to consider. Take the screen size as the perfect pair of shoes, they have to fit just right! Too big, and you’ll feel overwhelmed; too small, and you’ll miss the detail.

No matter if you’re looking for the best budget TVs or the best TVs to buy overall, selecting the right size ensures an immersive viewing experience without straining your eyes.

Many people prefer 65” to 77” TVs for a great movie experience at home. On the other hand, gamers often choose 42” to 48” TVs to reduce eye strain, though larger sizes are still popular for console gaming. For those on a budget, the best budget TVs in the 50-55 inch range offer excellent value with 4K resolution and HDR support. If you're looking for the best TVs to buy, upgrading to a 65-inch or larger OLED or QLED model can provide a more cinematic experience with superior contrast and colour accuracy. 

How to Measure a TV and Determine the Right Size 

TVs are measured diagonally from corner to corner. However, bigger isn’t always better—you should also consider how far you’ll be sitting to get the best mix of screen size and comfort.

Display Technology 

We’ve already touched on TV types and display technologies in the earlier sections of our TV buying guide. 

Understanding TV types, such as OLED TVs, QLED TVs, energy efficient TVs, smart TVs, and display technologies is critical to choosing the right TV for your home.

For your convenience, here’s a quick breakdown. 

• LED (Light Emitting Diode): Budget-friendly, widely available. 
• QLED (Quantum Dot LED): Brighter colours, better HDR, good for bright rooms. 
• OLED (Organic LED): Deep blacks, superior contrast, best for cinematic experience. 
• Mini-LED & Micro-LED: More dimming zones, higher brightness, improving LED performance. 

Resolution: 4K, 8K, 1080P: What It Means for Your TV 

Resolution means the number of pixels on your screen. The more the pixels, the sharper the picture. 

Modern TVs typically have the following resolutions: 

1080p Full HD (1920 x 1080 pixels) - The classic but ageing option 

4K Ultra HD (UHD) (3840 x 2160 pixels) - Offer the best balance of price and picture quality. 

8K Ultra HD (7680 x 4320 pixels) - Amazing detail but requires a premium investment. 

 
Full HD screens are now somewhat ageing tech and outdated, mainly reserved for the smallest and most affordable models. 4K Ultra HD offers the ideal balance of price and picture quality, making it the best option for most users. 8K resolution offers mind blowing detail, but it’s currently available on expensive, big-screen TVs with little native content available. That means most of what you watch will be upscaled rather than true 8K. 

If you’re investing in an 8K TV, go for a more premium model from a trusted brand, like the Samsung 85” QN900D 8K UHD Neo QLED Smart TV. Samsung has consistently listed among the best TV brands and ranked as one of the top rated TV brands, standing out for its innovative features and wide range of options. 

Refresh Rate & Motion Handling 

Refresh rate and motion handling are essential for gaming and sports fans.  

The refresh rate in TVs, measured in Hertz (Hz), indicates how many times per second the screen updates its image.

In TV refresh rates, the common debate is 60Hz vs. 120Hz vs. 144Hz- which delivers the most fluid motion. As with TV resolution, a higher refresh rate in TVs results in more seamless movement, enhancing fast-paced action and gaming. 

60Hz- Standard for budget and mid-range TVs. Ideal for movies and casual viewing. 

120Hz+ - Great for sports and gaming. 

144Hz- Found in high-end gaming TVs and monitors, offering ultra-smooth gameplay. 

 
As a next-gen gamer, you must also look for VRR (Variable Refresh Rate), HDMI 2.1, low input lag, and fast response time in your TV.  

HDR (High Dynamic Range) 

If you’ve ever explored TVs, you must have come across the term HDR.  

HDR (High Dynamic Range) is a key factor that determines picture quality. It enhances the contrast and colour range of a TV, providing a more realistic and vibrant picture.

Essentially, HDR allows for brighter highlights and deeper blacks, revealing more detail in both bright and dark scenes. This results in a more immersive viewing experience, particularly noticeable on the best 4K TVs. 

Different HDR Formats and Their Meaning 

HDR10 (Standard HDR)- Most common HDR format, used in most TVs, streaming platforms, and gaming. 

HDR10+ and Dolby Vision- Best for movies, featuring dynamic metadata to adjust HDR effect scene-by-scene for enhanced accuracy. 

HLG (Hybrid Log-Gamma)- Designed for live TV and broadcast content, ensuring compatibility with both SDR and HDR displays. 

When selecting a TV, consider which HDR format it supports. Dolby Vision and HDR10+ often provide the most visually compelling experience. 

Smart TV Features & Operating Systems 

You've considered picture and motion, but what about the 'smart' side of your TV?  

In this part of our TV buying guide, we will break down popular smart TV platforms, streaming app options, and the difference between ad-supported vs premium smart TVs, helping you pick the best one for your needs.  

If you’re choosing a Smart TV, consider the following factors: 

Operating System 

• Look for Android TV / Google TV if you need versatility, access to a wide range of apps, and Google Assistant integration. 
• Go for webOS (LG) if you prefer a user-friendly interface, smooth performance, and strong app support. 
• Opt for Tizen (Samsung) if you want a fast, intuitive OS with a clean layout but are okay with fewer apps than Google TV. 
• Roku TV / Fire TV / Apple TV integration if you love streaming, want a simple interface, and prefer a budget-friendly option. 

Streaming App Compatibility 
 

Make sure the TV supports your favourite streaming apps like Netflix, Disney+, Prime Video, and YouTube.  

Voice Assistants & Smart Home Integration 

If you use Alexa or Google Assistant, check if the TV supports them for smart home integration and hands-free control. 

Ad-Supported vs. Premium Smart TVs 

Ad-supported Smart TVs- Have lower upfront costs but display ads. 

Premium Smart TVs- Have a higher cost but offer ad-free navigation and sometimes extra features. 

Connectivity – Ports and Wireless Features 

When getting into TV buying, don't just get caught up in the screen size and fancy picture tech – you've got to think about Connectivity (Ports and Wireless Features). Trust me, you'll thank yourself later when you're not scrambling for an extra HDMI port or dealing with spotty Wi-Fi during movie night! 

• Essential Ports to Look For: HDMI 2.1 (crucial for next-gen gaming and future-proofing), USB (handy for external storage and media playback), Optical Audio, Ethernet, ARC/eARC for seamless soundbar integration. 
• Key Wireless Features: Wi-Fi 6, Bluetooth, Chromecast and AirPlay compatibility. 

Audio Quality & Sound Systems 

Though it's always convenient to have a TV with built-in speakers, they are not always sufficient. This is because they typically lack depth and power. For an immersive sound experience, external audio is recommended.

In 2025, we have exceptional audio-quality TVs and sound systems, including soundbars for TVs such as the Sony BRAVIA Theatre Bar 9, Samsung HW-Q930D, and Sony BRAVIA Theatre Bar 8. 

If you’re looking for the best audio equipment for TVs, consider one with Dolby Atmos & DTS:X support. Soundbars that support both Dolby Atmos & DTS: X are LG US70TY Dolby Atmos Sound Bar for TV, Sony Bravia Theatre Bar 8 HTA8000 Soundbar, and Sony HT-S2000 Dolby Atmos Soundbar.  

For external audio, one of the best ways to go is a sound bar but the option of home theatre is also there. Ultimately, soundbar vs. home theatre comes down to your budget.  

If you’re on a budget: Soundbars significantly enhance audio quality and are often included in smart TV deals. 

If you’re not on a budget: Home theatre systems deliver the most immersive experience, but at a higher cost. 

AI Processing: Smart Optimisation for Stunning Results 

Viewers with large libraries of older content, those seeking the best possible picture quality, regardless of the source, and gamers wanting smoother upscaling can benefit from AI processing in modern TVs.  

With AI processing, the TV intelligently adapts to every scene, transforming standard content into near-4K quality, making it a key factor in selecting the right TV. AI processing also optimises sound quality, complementing the best soundbars for TV and future-proof your TV against evolving content standards. Few top TVs with AI processing are the LG OLED Evo C4 Smart TV, Samsung QN90D, and Samsung S90D. 

Dimming 

Dimming enhances contrast for lifelike images, specifically in dark scenes. It can be specifically valuable for movie lovers.

Wall Mounting 
 

Try getting a TV that supports wall mounting, as wall mounting frees up space and adds a clean aesthetic. Prioritise VESA support for easy setup.  

Budget Considerations and Value 

No TV buying guide is complete without considering your budget and identifying the best value options. Here’s what you can expect from different price ranges in 2025. 
 

Budget (<£500):  
 

• Expect basic LED TVs, often with 1080p resolution or entry-level 4K models. Good for casual viewing.

TVs Under 500

Mid-Range (£500-£1500):  
 

• Offers QLED and OLED options, 4K HDR, and improved processing. These TVs balance features and price, making them ideal for most users. 

TVs 500-1500

Premium (£1500+):  
 

• Features high-end TVs with OLED or QLED technology, 8K resolution, and advanced AI processing. Best for the ultimate viewing experience.

TVs 1500+ 

Best Value for Money

To get the best value for your money, carefully weigh a TV’s features against your budget. Mid-range TVs often provide the best balance of quality and affordability, making them a great choice for the average user. 

To maximise your investment, don't get distracted by every bell and whistle. Ask yourself, 'will I actually use this?' and let that guide your decision. 

Best TV Brands

While many TV brands are available, only the best TV brands offer top-tier quality and performance. Choosing the right one depends on your needs—whether you're looking for the best budget TVs, top rated smart TVs, or energy efficient models. 

That said, here’s a look at the top TV brands in 2025.
