Our Take

Best for: Budget-conscious viewers wanting QLED color and smart features.

The Samsung QEF1 delivers impressive picture quality for its price. The Q4 AI Processor upscales content to near-4K detail, and Quantum HDR+ enhances brightness and contrast. Motion Xcelerator 144Hz effectively reduces blur during fast action, though the panel is natively 60Hz. Samsung's smart platform offers thousands of free channels via Samsung TV Plus, and the Solar Cell Remote is a nice eco-touch. Color volume is strong thanks to Quantum Dot technology, and the slim design looks modern. Build quality is solid, and gaming features include Auto Low Latency Mode (ALLM) for snappy response. The main tradeoff is the lack of Dolby Vision - HDR10+ is supported instead. 1 bandwidth is limited, so next-gen console users may miss 120Hz gaming. At this all-time low price, it's a fantastic value for viewing and streaming.

Price Analysis

At $359.99, this is the lowest price ever for the QEF1 - a 40% drop from the $599.99 original. The 30-day average matches the sale price, so you're getting the best deal available. Highly recommended to buy now.

Common Questions

Does this TV support Dolby Vision?

No, Samsung uses HDR10+ instead of Dolby Vision. Content mastered in HDR10+ will look excellent, but Dolby Vision sources will fall back to standard HDR.

What is the native refresh rate?

The panel is 60Hz native, but Motion Xcelerator 144Hz uses interpolation to smooth fast-moving scenes, making it suitable for and action movies.

Can I use this TV for gaming?

Yes, it supports Auto Low Latency Mode (ALLM) for low input lag, but it lacks HDMI 2.1 for 4K 120Hz. It's fine for casual and last-gen console gaming.
