Top 5 Best 4K 120Hz Projector in 2023

Welcome to our guide on the top 5 best 4K 120Hz projector in 2023! A 4K 120Hz projector can display ultra-high definition images at up to 120 frames per second, providing an incredibly smooth and realistic viewing experience.

With 4K resolution and high refresh rates becoming more popular, especially for gaming, there is growing demand for projectors that can keep up. In this guide, we will take a look at the top projector on the market right now that support 4K 120Hz.

What to Look for in a 4K 120Hz Projector

When shopping for a 4K 120Hz projector, there are a few key specifications and features to keep in mind:

  • Resolution and Refresh Rate: Of course, you want to ensure the projector supports true 4K resolution (3840 x 2160 pixels) and a high refresh rate of at least 120Hz. This allows you to view native 4K content at the full 120 frames per second for silky smooth motion.
  • Brightness: Projector brightness is measured in lumens. For decent 4K picture quality, you’ll want a projector rated for at least 3000 lumens. Higher lumens ratings like 4000+ are recommended for better brightness.
  • Contrast Ratio: A high contrast ratio of 50,000:1 or more results in deeper blacks, brighter whites, and sharper detail. Look for projectors with a native contrast ratio of at least 50,000:1.
  • Inputs and Connectivity: Make sure your 4K 120Hz projector has HDMI 2.0 or greater inputs that support 4K at 120Hz signals. Other useful connectivity options include USB, Ethernet, Wi-Fi, and Bluetooth.
  • Low Input Lag: Input lag refers to the delay between an input being initiated and the response showing on screen. For gaming and live sports, low input lag under 50ms is crucial for a responsive experience.

With these factors in mind, let’s look at 5 of the best 4K 120Hz projectors available today!
