This 55″ LG OLED TV on Alza has never been cheaper! Users love it

LG OLED TVs have long been among the highest-rated models on the market, but the premium C-series has never been a cheap affair. However, the LG OLED55C54 model has now dropped from the usual 25,490 CZK to 21,667 CZK with AlzaPlus+ membership, which represents the lowest price it has ever been available for on Alza. It boasts smart features and a high refresh rate in gaming mode.

Quick summary:
✅ Makes sense if you’re looking for a 55″ 4K OLED TV for movies, sports, and modern gaming consoles, and you want to get an LG C-series at the historically best price.
⚠️ Consider if you have a very bright room and expect maximum SDR brightness, or if you prefer a TV with Ambilight or with built-in speakers without the need for a soundbar.
💡 At 21,667 CZK, this is the most affordable price for this LG C5 on Alza ever – comparable OLED TVs usually cost significantly more.

Why this OLED TV is interesting

LG OLED55C54 belongs to the popular C-series for 2025, which foreign reviews have long described as one of the most balanced OLED models on the market. From its original 44,990 CZK upon launch in May 2025, the price gradually decreased, and in the current promotion, with AlzaPlus+ membership, it reaches 21,667 CZK. This is the absolute lowest this TV has ever cost on Alza – a drop of almost half since its premiere.

At this price point, you usually encounter better QLED or Mini LED models, but for a true OLED with perfect black, you have to reach higher. The C5, however, adds the alpha 9 AI Gen8 processor, which handles upscaling, image and sound optimization, and complete gaming features including NVIDIA G-SYNC and AMD FreeSync Premium. For someone who was considering a cheaper LCD, this is a specific opportunity to move into the OLED category without a premium surcharge.

Most important TV parameters

At the heart of the TV is an OLED panel with a resolution of 3840 × 2160 pixels and a diagonal of 139 cm. Unlike LCDs, individual pixels here light up on their own – the result is perfect black without light bleed, high contrast, and very fast response. The panel natively operates at 100/120 Hz and in gaming mode handles 144 Hz at 4K, which will be especially appreciated by owners of more powerful PCs and PlayStation 5 or Xbox Series X consoles.

The image quality is enhanced by Perfect Black technology with UL certification and support for a wide range of HDR formats – specifically HDR10 Pro, HLG Pro, and Dolby Vision IQ. For filmmakers and cinema fans, there’s FILMMAKER MODE, which keeps the image closer to the director’s intent and compensates for ambient light. The anti-reflective surface suppresses glare, although for OLEDs, it generally holds that in brightly lit rooms, viewers will appreciate QLED or Mini LED more due to their higher maximum brightness.

Sound is handled by 40W speakers with Dolby Atmos support and algorithms that create virtual 11.1.2 surround sound. For casual TV and series viewing, this is decent equipment, but for a true cinema experience, it’s worth buying a soundbar – after all, this applies to practically every modern TV with a slim profile.

Practical aspects: ports, control, and AlzaPlus+ membership

In terms of connectivity, you get 4× HDMI 2.1, 3× USB, Bluetooth, Wi-Fi, and support for Apple AirPlay 2 and Chromecast. Four full-fledged HDMI 2.1 ports are a big advantage in this category – you can connect PlayStation 5, Xbox Series X, and a gaming PC simultaneously without compromise. However, one specific criticism emerges from reviews: the LAN port is only 100Mb, so for extreme 4K HDR streams over a wired network, 5GHz Wi-Fi or network storage via USB is more advisable.

The WebOS 25 operating system is among the fastest on TVs, and LG also guarantees 4 major updates over 5 years as part of the Re:New program. Control is handled by the Magic Remote, which functions as a motion pointer – some users love it, others can’t get used to it (more on this in the reviews section).

The price of 21,667 CZK is valid only for members of the AlzaPlus+ program. Membership costs 299 CZK annually (i.e., 25 CZK per month) or 59 CZK per month without commitment. In addition to this discount, you get free delivery to all pick-up points without a minimum order value – AlzaBoxes, Zásilkovna, PPL ParcelShop, and Czech Post.

What users say

On Alza, the TV has a rating of 4.9 out of 5 (64 ratings) and 97% of customers recommend it. The complaint rate is low (0.48%), and over 1,000 units of the TV have already been sold. Users most often highlight the quality of the OLED panel, black color reproduction, and fast response – exactly what you expect from the OLED category. Praise for WebOS and gaming mode with ALLM/VRR in conjunction with consoles appears repeatedly.

Critical voices mainly appear regarding details: The Magic Remote with its scroll wheel doesn’t suit everyone (“motion control sometimes slightly drifts”), there are pre-installed ads in the menu (can be blocked at the DNS level), the speaker sound is “better than before, but for a large room, a soundbar will help.” A few users mention that the TV does not support all video formats from external USB drives (typically less common containers), which might bother people with an extensive movie library on disk.

If this particular model didn’t appeal to you, but you’re looking for a premium TV on sale, you can also check out the current Alza Days, where other discounted OLED and Mini LED TVs regularly appear. However, the offer changes continuously according to stock levels.

When it doesn’t make sense

The discount is significant, but this TV is not for everyone. If you have a very bright room with large windows and mostly watch during the day, you’ll appreciate TVs with higher maximum SDR brightness more – typically QLED or Mini LED. While OLED panels have excellent color reproduction in ideal conditions, they lose their appeal in full sunlight.

A second reason to consider a different model: if you’re a fan of Philips Ambilight or want a TV as a purely plug-and-play solution without any tweaking, the LG C-series requires a bit of attention during initial setup – especially for HDR and gaming mode. And thirdly: if you don’t want to pay for AlzaPlus+, you must account for the regular price of 25,490 CZK, so the 3,823 CZK bonus is lost. For people who rarely shop on Alza, the membership will pay off more slowly.

Verdict: who it’s worth it for

If you want a 55″ premium OLED TV for a modern living room, for a console or movies, and you catch the price of 21,667 CZK with AlzaPlus+, this promotion is one of the best in terms of price/performance ratio that Alza has had this year. The LG C-series has a long-standing reputation as the most balanced OLED series on the market, and here you’re getting it at a price this model hasn’t seen on Alza before. Conversely, if you don’t want to pay for AlzaPlus+ or need a TV for a very bright room, it’s worth considering other panel categories – usually at a similar or higher price.
