What is contrast ratio, and how does it affect picture quality?

Contrast ratio measures the difference between the darkest blacks and the brightest whites a TV can display. A higher contrast ratio results in more detailed and vivid images, particularly in scenes with both light and dark elements. OLED TVs offer some of the best contrast ratios due to their ability to turn off individual pixels, resulting in perfect blacks. Meanwhile, LED and QLED TVs with good local dimming can also provide excellent contrast. If you're looking for a more immersive viewing experience, choosing a TV with a high contrast ratio is key.
