Shopping for a new 4K smart TV can be overwhelming, given the variety of options available. Whether upgrading your current model or buying your first 4K television, understanding the key features that affect performance is essential for making the best choice. From display quality to smart features, here are the factors to keep in mind when purchasing a 4K smart TV.

QLED, known for vibrant colours and high brightness, works well in bright rooms and is typically more affordable. Mini LED offers improved brightness control and deeper blacks, making it a great middle-ground option. Standard LED models, though cheaper, offer less precise contrast.

Many modern 4K TVs come with features like Variable Refresh Rate (VRR) and Auto Low Latency Mode (ALLM), ensuring an optimal gaming experience by minimising lag and screen tearing.
