10 Best 4 K TV 120 Hz 2026 in the United States

The LG 55-Inch OLED evo AI C5 Series TV is a strong choice for anyone wanting a high-quality 4K TV with a 120 Hz refresh rate. Its OLED panel offers excellent picture quality thanks to over 8 million self-lit pixels that deliver deep blacks and vibrant colors, making movies and sports look stunning even in bright rooms. The TV supports popular HDR formats like Dolby Vision and HDR10, enhancing color and brightness for a more lifelike experience. With the Alpha 9 Gen8 AI Processor, it upscales lower-quality content smartly, so everything looks clearer and more detailed. The 120 Hz refresh rate combined with very fast 0.1 ms response time means motion is smooth, ideal for fast-paced action and gaming.

It also includes advanced gaming features like NVIDIA G-Sync and AMD FreeSync Premium, plus four HDMI 2.1 ports for connecting multiple devices easily. Smart TV functions are solid, with built-in Alexa, Google Cast, and multiple voice assistants making it easy to control the TV and stream content. Connectivity options cover Bluetooth, Wi-Fi, Ethernet, HDMI, and USB, covering most needs well. At 55 inches, it’s a good medium-to-large size for living rooms or gaming setups.

OLED TVs can be more expensive than LED alternatives, and while brightness is improved with the Brightness Booster, some users in extremely bright rooms may still find an LED TV more suitable. Additionally, OLED screens can be susceptible to burn-in with static images over time, so varied viewing habits help avoid this. This LG model delivers exceptional picture and sound quality, excellent gaming support, and user-friendly smart features, making it a great pick for movie lovers, gamers, and anyone wanting a premium 4K TV experience.

The Samsung 65-Inch OLED S90F is a strong choice for anyone looking for a large 4K TV with excellent picture quality. It uses OLED technology, which means deep blacks and vibrant colors, making movies, sports, and games look impressive. The 120 Hz refresh rate helps provide smooth motion, especially useful if you watch fast-paced content or enjoy gaming. This model also features HDR+, which enhances brightness and color contrast, delivering a more dynamic and lifelike picture. Its advanced AI processor uses neural networks to upscale lower resolution content to near 4K quality, so even non-4K shows look sharper. The TV supports HDMI, USB, Bluetooth, Ethernet, and Wi-Fi, offering plenty of options for connecting devices and accessing smart TV features, including built-in Alexa for voice control.

At 65 inches, it’s well-suited for medium to large rooms. One potential downside is that while the refresh rate specs highlight 120 Hz for general use, it mentions VRR gaming at up to 144 Hz, which might be confusing for users expecting consistent 144 Hz across all uses. Also, OLED panels can be pricier and may be less bright than some LCD alternatives in very bright rooms. Nevertheless, this TV balances a great screen size, smart features, and excellent picture quality, making it a solid pick for both everyday viewing and gaming.
