Screen size: OLEDs are available in sizes from 40 inches to 97 inches, and there are probably even bigger TVs coming in the future. One of the best pieces of advice we can give is, if you can afford it, always buy a TV one size bigger than you think you need. While 65 inches is the norm right now, TVs will keep getting bigger year after year, and you might consider buying a 77-inch to prevent an upgrade in the near future. However, if you’re buying for a bedroom or a games room, then you could look at TVs 55 inches or under.

Consider older models: At the affordable end of OLED, the yearly model updates aren’t as dramatic when compared with the flagships. For TVs like the LG B4 or even C4, for instance, it makes sense to compare prices on last year’s model and get whichever is cheapest. In the meantime, 2025 models have just started appearing in stores and so you should expect to see 2024 prices to start falling as well.

HDR formats: While it’s not completely necessary, compatibility with Dolby Vision is a plus. Of course, Samsung doesn’t support the Dolby format and instead offers its own version it calls HDR10 plus, and this is gaining in popularity. In the end, though, almost every 4K TV supports HDR 10, and this will work just fine.

Gaming: If you’re a gamer then having gaming-enhancing features is a bonus, and these includes a dedicated gaming mode (for turning off processing and reducing lag), 120Hz or higher support and even gaming apps such as Xbox Game Pass, Amazon Luna and Steam Link.

Operating system: With the introduction of the Philips Roku TV most types of smart TV interfaces are now available on OLED televisions. Whether its Google TV, Roku or one of the manufacturer-specific systems opting for a popular smart TV interface gives you the most choice when it comes to apps and on-demand content.
