The TV's gaming features, including 144Hz support and VRR, are also a major draw.
“I was on the fence about spending this much on a renewed TV, but honestly, watching Top Gun: Maverick in 4K on this 77-inch OLED blew me away, even my wife noticed the difference, totally worth it.”

Frequently Asked Questions
What does 'Renewed' mean for this TV?
It means the unit is manufacturer-refurbished, fully tested to perform like new, and comes with a 90-day warranty for your peace of mind.
Does this TV support 120Hz for gaming?
Yes, it has a 120Hz native refresh rate and can even go up to 144Hz for PC gaming, with support for VRR, G-SYNC, and FreeSync Premium.

While burn-in is a theoretical concern for OLEDs, many users report it's rare with typical viewing habits, and modern OLEDs have features to mitigate it.
How many HDMI 2.1 ports does it have?
It features four HDMI 2.1 inputs, which is ideal for connecting multiple next-gen consoles or a high-end PC.

Buying Guide
When you're looking at a TV this size, especially an OLED, you're buying into a premium visual experience. The 'Renewed' tag means you're getting a manufacturer-refurbished unit, which usually means a lower price but a shorter warranty. For a 77-inch screen, you need adequate viewing distance to fully appreciate the 4K resolution without individual pixels becoming visible.
OLED Panel
Unlike traditional LED TVs that use a backlight, each pixel in an OLED TV lights itself. This means you get 'perfect blacks' because pixels can turn completely off, leading to infinite contrast and colors that really pop, making movies and games look incredibly realistic.
120 Hz Native Refresh Rate (up to 144 Hz)
This is how many times the screen updates per second. A 120Hz native rate means motion looks incredibly smooth, especially for fast-paced sports or action movies, reducing blur. The 144Hz capability is a bonus for PC gamers with compatible graphics cards, offering an even smoother, tear-free experience.
HDMI 2.1 Inputs
These are crucial for modern gaming and high-bandwidth devices. They allow for 4K resolution at 120Hz (or even 144Hz), Variable Refresh Rate (VRR), and Auto Low Latency Mode (ALLM), ensuring the best possible experience with current-gen consoles and PCs by minimizing input lag and screen tearing.
Alternatives
If this 77-inch size is too large or the renewed status is a concern, consider models with similar OLED panel technology and HDMI 2.1 connectivity in a smaller screen size, or look for brand-new units with longer warranties.
