CHCI TELEVIZI V AKCI Quick Summary:✅ Makes sense if you want a large 77″ OLED TV for movies, sports, and gaming with perfect blacks and top-notch gaming features.⚠️ Consider if you have a very bright room with direct sunlight or want premium sound without a soundbar.💡 For 39,989 CZK, this is one of the best prices you’ll find for a 77″ OLED C5 this year – you save 50,000 CZK compared to its launch price. Why this TV is interesting The C series has long been LG’s most versatile OLED choice, and reviewers repeatedly call it the best TV for most people. The main advantage of an OLED panel is perfect blacks with infinite contrast – each pixel illuminates itself, so dark scenes look realistic without light bleed. On a 77″ diagonal, this creates a true home cinema experience. When the price dropped to 39,989 CZK, this diagonal in an OLED version becomes accessible within a budget where smaller models or LCD TVs used to be. Key parameters explained in plain language At the heart of the TV is the alpha 9 AI Gen8 processor, which, through AI Picture Pro and 4K upscaling, enhances even lower-quality content and optimizes brightness, colors, and sharpness in real-time. The OLED evo panel with Brightness Booster is significantly brighter than older OLED generations, so it can handle a normally lit living room. In terms of HDR formats, the TV supports Dolby Vision IQ, HDR10 Pro, and HLG Pro. Sound is handled by a 40 W system with Dolby Atmos and virtual surround mode AI Sound Pro. For gamers, the C5 is exceptionally well-equipped: it offers a refresh rate of up to 144 Hz, NVIDIA G-SYNC, AMD FreeSync Premium, VRR, and ALLM, plus a very low response time of 0.1 ms certified by Intertek. Thanks to four HDMI 2.1 ports, you can connect PlayStation 5, Xbox Series, and gaming PCs without compromise, and the gaming portal also offers cloud gaming via GeForce NOW. KOUPIT ZA 39 989 KČ Practical aspects: system, ports, design The software runs on the webOS operating system with the AI Magic Remote controller, which functions as a pointer (air mouse) and handles voice commands. LG also promises 5 years of updates thanks to the webOS Re:New program. Connectivity includes 4× HDMI, 3× USB, LAN, Wi-Fi, Bluetooth, and eARC for soundbar connection, plus AirPlay 2 and Chromecast for phone mirroring. The TV has an ultra-thin design suitable for wall mounting (VESA attachment), but account for space for the 77″ diagonal and a weight of around 27 kg with the stand. What to watch out for Even premium OLED has its compromises. Although the C5 is brighter than earlier OLEDs thanks to Brightness Booster, in an extremely bright room with direct sunlight, Mini-LED or QD-OLED TVs can offer higher peak brightness. Furthermore, LG does not support the HDR10+ format (it relies on Dolby Vision), which might be a factor for some content on Amazon. The built-in 40 W sound is decent for its category, but for a 77″ TV, many will appreciate purchasing a soundbar. And as with all OLED panels, for long-term display of static content, it’s good to consider burn-in prevention, which the TV itself addresses with automatic functions. Verdict: who it’s worth it for If you want a large 77″ OLED TV for movies, sports, and gaming and are looking for a top-notch picture with perfect blacks, the LG OLED77C54LA for 39,989 CZK is one of the most interesting offers of the year – it’s a significant drop compared to its launch price of 89,989 CZK and also compared to 49,989 CZK from the end of last month. Conversely, if you have a very bright room with direct sunlight or want premium sound without a soundbar, it’s worth considering brighter models like the LG G5 or Mini-LED competitors – but they will usually be more expensive at this diagonal.
