TV size TV manufacturers advertise their products in inches rather than centimetres. We provide screen measurements in both so you can decide which figure is more suitable. Medium (121cm - 160cm, 48" - 63") Display type In our latest test, the screens are either LCD or OLED. An LCD (liquid-crystal display) screen needs a light source behind it. OLED or Organic Light Emitting Diode TVs are an array of diodes that deliver both the colour information as well as the illumination. LCD Recommended CHOICE recommends TVs that earn an overall score of more than 75% and at least 70% for standard definition (SD) and high definition (HD) picture quality performance. CHOICE Expert Rating This overall score is made up of high definition picture quality (25%), standard definition picture quality (15%), Filmmaker Mode picture quality (10%), user interface (10%), remote control (10%), smart TV (10%), 4K picture quality (5%), EPG (5%), energy consumption (5%) and sound quality (5%). Voice assistant scores are not included in the CHOICE Expert Rating. High definition picture quality score Online streaming routinely delivers high definition-quality video and most of the free-to-air stations now broadcast HD content on their main channel. HD accounts for 25% of the CHOICE Expert Rating. Standard definition picture quality score Many TVs with very high resolution struggle to upscale standard definition (SD) sources to their native resolution, leading to low scores in our testing for SD. SD accounts for 15% of the CHOICE Expert Rating. 4K video picture quality score Online streaming increasingly delivers 4K-quality video and we look at 4K content to see which TVs deliver the best overall picture. The 4K assessment accounts for 5% of the CHOICE Expert Rating. Filmmaker Mode score Filmmaker Mode disables most of the post-processing on your TV (such as colour adjustments and image smoothing) to deliver a more cinematic picture that's as close to the director's original intentions as possible. If Filmmaker Mode isn't available, we test in the manufacturer's Movie/Cinema mode. This assessment accounts for 10% of the CHOICE Expert Rating. User interface score The on-screen user interface should be easy to read, easy to follow, tell the user what is happening (e.g. tells the user to wait while TV is scanning for DTV broadcasts), and show clear prompts, which button to press, or what to do next. User interface accounts for 10% of the CHOICE Expert Rating. Remote score The tester checks the size and spacing of the buttons, dials or touch pads to make sure they're easy to reach, logically grouped and not too close together. Labels should be big enough to read and of sufficient contrast to be easy to read in low light. The remote's overall size and shape is assessed for how well it fits in the hand and how easy it is to use with one hand. Remote accounts for 10% of the CHOICE Expert Rating. Sound quality score The tester plays a number of high quality voice and music recordings on a DVD player connected to the TV and compares it to a reference system. The assessment is made at a volume that the tester feels is sufficient for listening in a normal room and also at the TV's maximum volume (assuming the latter is louder). Sound quality accounts for 5% of the CHOICE Expert Rating. Energy score We measure standby and in-use energy to determine an annual cost to run the TV, assuming you watch 10 hours of TV a day and leave the TV in standby when not in use. Energy accounts for 5% of the CHOICE Expert Rating. EPG score EPG refers to the electronic program guide. This accounts for 5% of the CHOICE Expert Rating. Smart TV score We have increased our testing in this area as TVs become an intrinsic part of the modern smart home. The smart TV assessment accounts for 10% of the CHOICE Expert Rating. Voice assistant score This is an assessment of the ability of the TV to understand commands and questions from the user with the TV's integrated voice assistant feature and/or the smart assistant such as Google, Siri, Alexa etc. This score doesn't count towards the CHOICE Expert Rating. Shop Ethical rating Shop Ethical rates the environmental and social impact of the company (not the product) using independent sources. This rating is not included in our total score. N/A means there is no rating for that company. D Energy star rating As claimed by the manufacturer. The higher the number, the more energy-efficient the TV. 4 Claimed energy use (kWh/year) Energy use as claimed by the manufacturer. Based on 10 hours in use and 14 hours in standby mode for 365 days. Reliability score A high score means the TV brand (not the model) is less likely to have faults over time, according to CHOICE members. This score does not contribute to the CHOICE Expert Rating. Satisfaction score A high score means CHOICE members are satisfied with the brand (not the model). This score does not contribute to the CHOICE Expert Rating.

Yes High Dynamic Range (HDR) support High Dynamic Range (HDR) TVs deliver greater contrast between dark and bright colours, giving you greater detail in shade areas and more realistic colours in difficult video situations such as overly dark or overly light scenes. However to enjoy HDR, you need a TV to support the format and the content needs to have the information stored in the video to let the TV know how to deal with the picture.
