Samsung OLED TV under 20 thousand! It has 120 Hz, Dolby Atmos, and an AI processor

A Samsung OLED TV for the price at which cheap Mini LED models are usually sold. The Samsung QE55S84F currently costs 19,990 CZK on Alza – a nearly half-price drop from the original 37,990 CZK. For this price, you get all the advantages of an OLED panel: perfect black, pixel dimming, and wide viewing angles. You can find the current price and availability in the product detail on Alza.

Quick summary:
✅ Makes sense if you want a 55″ OLED with gaming features on all HDMI ports and don’t want to pay over 25 thousand for it.
⚠️ Consider if Dolby Vision is important to you – Samsung traditionally doesn’t support it. If Dolby Vision is crucial for you, the LG B5 is an alternative.
💡 For 19,990 CZK you get an OLED with 120 Hz, HDR10+, Dolby Atmos, an AI processor, and 7 years of updates

Why OLED and why the S84F specifically

The Samsung QE55S84F is Samsung’s entry-level OLED for 2025, but “entry-level” doesn’t mean stripped down. Self-illuminating pixels ensure perfect black without blooming, contrast is virtually infinite, and viewing angles are significantly better than any LED/Mini LED panel. The NQ4 Gen2 AI processor with 20 neural networks optimizes the image in real-time – including upscaling older content to near-4K quality.

For gamers, it’s crucial: 4K at 120 Hz on all four HDMI ports, FreeSync Premium, ALLM (Auto Low Latency Mode), and a gaming bar with support for ultrawide aspect ratios of 21:9 and 32:9. This is equipment that you won’t always find on all ports of competing OLEDs at this price. The anti-reflective surface helps in brighter rooms.

Sound, smart features, and what’s missing

The speakers have a power output of 20 W with support for Dolby Atmos, Object Tracking Sound Lite, and Q-Symphony (synchronization with a Samsung soundbar). For casual viewing, this is sufficient; for a cinematic experience, we recommend a soundbar. The Smart TV runs on Tizen with access to Oneplay, Netflix, Disney+, YouTube, and more. Samsung guarantees 7 years of updates. The SmartThings hub allows you to control your smart home directly from the TV. The SolarCell remote control charges with light.

What’s missing: Dolby Vision – Samsung doesn’t support it and instead relies on HDR10+. If you frequently watch content on Apple TV+ or other platforms with Dolby Vision, this is a relevant compromise. The LG B5 offers Dolby Vision at a similar price, but it lacks an anti-reflective surface and some gaming features on all ports.

Verdict

A 55″ Samsung OLED for 19,990 CZK is a price at which decent Mini LED TVs were sold not long ago. Perfect black, 120 Hz, gaming features on all HDMI, Dolby Atmos, AI upscaling, and 7 years of support – if you don’t need Dolby Vision, it’s currently one of the best buys in the OLED TV category. You can find other discounted TVs in the current Alza Days.

Have you switched to OLED, or is LED/Mini LED enough for you? Can you tell the difference in practice?
