Frequently asked questions
What is price per megapixel on a TV?
Price per megapixel divides the TV's price by its total pixel count (width × height). A 4K TV has about 8.3 million pixels, so a £400 set works out to roughly £0.05 per megapixel. It helps compare value across different resolutions and screen sizes.
What resolution TV should I buy in 2026?
Full HD (1080p) is fine for smaller sets under 43 inches. For 50 inches and above, 4K UHD is the standard — most streaming and broadcast content is available in 4K. OLED and QLED 4K sets offer the best picture quality if budget allows.
Is OLED worth the extra cost over LED?
OLED TVs deliver perfect blacks and excellent contrast because each pixel emits its own light. They are ideal for dark rooms and cinematic viewing. QLED and Mini LED sets are brighter and often better value for well-lit living rooms.
What screen size TV do I need?
As a rule of thumb, sit about 1.5× the screen diagonal away for 4K. A 55-inch TV suits most living rooms; 65-inch and above works well in larger spaces. Our comparison table lets you filter by screen size to find the best deals.
Why compare TVs by pixels?
A TV's headline price tells you little about value. A £300 32-inch HD set and a £600 55-inch 4K set have very different pixel counts — comparing by price per megapixel reveals which gives you more screen real estate and sharper picture for your money.
