This 55″ LG OLED TV keeps getting cheaper! On Alza, it costs almost half its original price, has 120 Hz and great features

The LG C-series OLED has long been among the best-selling OLED TVs on the market, and the C54 model continues this trend. You can now get the 55″ LG OLED55C54 for 22 941 Kč by entering discount code AUDIOVIDEOTYDNY10. For comparison — when launched last June, it started at 44 990 Kč. The current price is thus almost half of the launch price, making it one of the most interesting 55″ OLED offers on the Czech market.

Quick summary:
✅ Makes sense if you’re looking for a 55″ 4K OLED for movies, series, and games and don’t want to spend over 30 thousand.
⚠️ Consider if you need top-notch sound without a soundbar or have a very bright room with direct sunlight.
💡 For 22 941 Kč, you get an OLED panel with an alpha 9 AI Gen8 processor, 144Hz gaming mode, and G-SYNC compatibility — a combination that cost double just a year ago.

Why this TV is interesting

The LG C-series has been a “gold standard” among OLED TVs for years — offering premium picture quality without the need to pay for the absolute top-tier G-series. The OLED55C54 model targets those who want perfect blacks, high contrast, and excellent viewing angles, but at the same time don’t want to exceed the 25 thousand mark. And at the current price of 22 941 Kč, you’re well below that threshold.

Compared to cheaper LCD/LED TVs, the difference is immediately noticeable — especially in night scenes of movies or in games with dark environments. Each pixel lights up independently, so black is truly black, not dark gray. You’ll appreciate this when watching Netflix, HBO Max, and when gaming on a console.

Picture and processing: what do you get for 23 thousand?

The resolution of 3840 × 2160 px (4K Ultra HD) on a 55″ diagonal means a fine and sharp picture, whether you’re watching 4K content or letting the TV upscale lower resolutions. This is handled by the alpha 9 AI Gen8 processor, which uses artificial intelligence algorithms to optimize the picture in real-time — it recognizes the type of content (movie, sport, game) and adjusts parameters accordingly.

The panel supports HDR10, HLG, and Dolby Vision IQ, which in practice means a wider dynamic range and more accurate colors for compatible content. Perfect Black technology with UL certification ensures true black reproduction even in various lighting conditions — although it’s fair to say that in very bright rooms with direct sunlight, you’ll perceive reflections more than with some competing LCDs with higher brightness.

Gaming on this TV: PS5, Xbox, and PC

For gamers, the C54 is one of the best choices in this price category. It offers a 144Hz refresh rate in gaming mode (at 4K resolution), support for both NVIDIA G-SYNC and AMD FreeSync Premium, automatic low latency mode (ALLM), and VRR to eliminate screen tearing. All four HDMI ports are version 2.1, so you can utilize the full potential of both PS5 and Xbox Series X.

Thanks to OLED technology, the response time is practically instantaneous — the manufacturer states 0.1 ms (grey-to-grey) with Intertek certification. In practice, this means you won’t see motion blur even in fast-paced FPS titles or racing games.

Practical aspects: system, control, connectivity

The TV runs on webOS with a guarantee of 4 major updates over 5 years, which is above standard in the TV world. All common streaming applications (Netflix, HBO Max, Disney+, Apple TV+, Prime Video), Chromecast, and AirPlay 2 are available. The package includes a Magic Remote — a controller that functions as an “air mouse” and allows you to control the cursor with hand movements.

Physical ports include 4× HDMI 2.1, 3× USB, an optical audio output, and a CI+ slot. Wall mounting is possible thanks to VESA 300×200, and the TV’s weight without the stand is 14.1 kg. The built-in speakers have a power output of 40 W with support for Dolby Atmos and virtual 11.1.2 channel surround sound.

What do users say?

On Alza, the OLED55C54 has a rating of 4.9 out of 5 from 61 customers, with 98% of them recommending the TV. Over 1,000 units have already been sold, and the return rate is very low (0.38%). Users most frequently praise the picture quality, perfect blacks, fast response time, and price/performance ratio. Praise for the Magic Remote and the overall responsiveness of the webOS system appears repeatedly.

Critical voices are mainly directed at the sound — although it’s decent for TV standards, more demanding users recommend a soundbar. Several reviews mention ads in the webOS menu, which can be turned off in the settings. Occasionally, there are complaints about the Magic Remote (the “mouse” mode requires getting used to) and that the TV does not play all video formats from external drives. One user also points out reflections in a bright room — but this is a general characteristic of OLED panels.

When it doesn’t make sense

If you have a very bright room with direct sunlight hitting the screen, OLED might not be the ideal choice — the maximum SDR brightness is lower than that of premium LCD/Mini LED TVs. Similarly, if you expect top-notch sound without additional accessories, you’ll need to consider purchasing a soundbar. And if you play a lot of videos from external drives in less common formats, verify compatibility beforehand.

Verdict: who it’s worth it for

The LG OLED55C54 is a great choice for those who want premium OLED picture quality for movies, series, and games, but don’t want to pay 30+ thousand. For the current 22 941 Kč (with code AUDIOVIDEOTYDNY10), you get a TV that cost almost double a year ago — and the specifications remain the same. If you’ve been waiting for the right moment to upgrade, this price is very compelling.
