How to Avoid 6 Common Mistakes When Setting Up Your New TV

Setting up a new TV is an exciting experience. Whether upgrading from an old model or finally treating yourself to a new one, it’s all about enjoying better visuals and sound while indulging in your favorite movies and shows. However, when you get your new TV home and set it up, it may not look quite as you imagined. Don’t worry, you’re not alone in this! TVs often come with hidden settings that can significantly impact their performance. This issue is not limited to budget models; even high-end TVs come with frustrating default settings. While everyone has their preferences regarding picture quality—some favor brighter, more vivid images, while others prefer a more natural look—there are some settings you should adjust for better viewing. Based on my experience in AV retail, I’ve compiled six common mistakes people make when setting up their new TVs. And don’t worry, I’ll guide you through how to correct them. 1. Disable Eco and Power Saving Modes If your TV looks a little lackluster, it’s likely in Eco mode. Most TVs ship with this mode enabled to save energy, but it can significantly reduce picture quality. Eco mode typically dims the screen, which dulls colors and detail, making your TV shows and movies appear washed out. To turn it off, go to your TV’s Settings > Picture Settings. You'll likely find the Picture Preset set to Eco by default. Switch it to Movie, Filmmaker, or Standard for a more accurate and brighter image. Additionally, check for any hidden power-saving options under System Settings > Power Saving to ensure nothing else is affecting your display. 2. Switch Out of Dynamic or Vivid Mode Dynamic or Vivid modes may seem like a good option for a brighter image, but they tend to oversaturate colors and lack detail. While the brightness might be appealing at first, it creates an unrealistic image. To get a more natural look, switch to modes like Filmmaker or Movie. Top TV brands like Samsung, known for their Dynamic mode, now recommend Filmmaker and Movie modes for better quality, especially in newer models like the Samsung S95D OLED and QN90D mini-LED. 3. Check for Software Updates While many TVs automatically check for updates during the initial setup, it’s always worth manually verifying if the latest software is installed. Updates are essential not only for new features but also for security, especially with smart TVs that are internet-connected. Go to System Settings > Check for Update or Software Update to ensure your TV is up to date. 4. Adjust Motion Smoothing Settings Motion smoothing, or motion interpolation, is a setting that smooths out fast-moving images by adding extra frames to reduce blur. While useful for sports, it can make movies look unnatural, even causing motion sickness for some viewers. To disable or adjust it, go to Picture Settings > Motion and look for Blur Reduction and Judder Reduction options. Depending on whether you're watching sports or a movie, you may want to turn motion smoothing off or reduce its intensity for a more realistic image. 5. Enable Enhanced HDMI Settings for Gaming For gamers, enabling Game Mode is essential, but it’s equally important to check your TV’s HDMI settings to ensure full 4K support. TVs with HDMI 2.1 support 4K at 120Hz, but only if the HDMI setting is set to Enhanced. Navigate to Settings > HDMI Control, and select Enhanced to activate these features, ensuring optimal performance for gaming. 6. Fine-tune Sharpness and Detail Enhancements Many TVs come with additional settings to enhance sharpness, resolution, and color. While some people enjoy these effects, they can often make the image appear artificial or overly sharp. For example, the Super Resolution feature on Hisense TVs can make textures look unnaturally crisp. It's best to use these enhancements sparingly, if at all, and find a picture preset that suits your tastes. For the most accurate viewing, disable features like Noise Reduction and Resolution Remaster, especially when using more precise picture modes like Filmmaker. Remember, the goal is to customize the settings until you find the picture quality that works best for you, balancing personal preferences with the TV’s capabilities.
