LG OLED evo C5 review
Overview and generation status
The LG OLED evo C5 is LG's 2025 mainstream premium OLED television and is now previous-generation hardware following the 2026 C6. That does not make it obsolete. The C5 remains one of the most complete discounted televisions for mixed films, streaming, sport and gaming because it combines pixel-level OLED contrast with four high-bandwidth HDMI inputs, broad gaming support and LG's mature webOS platform. Its strongest buying case in 2026 is value: it should be considered when it is meaningfully cheaper than an equivalent C6, not merely because a retailer describes old stock as a special edition.
The range spans compact gaming-friendly sizes through very large screens, but buyers should not assume every size performs identically. Smaller 42-inch and 48-inch versions have less surface area for heat dissipation and generally do not deliver the same HDR impact as larger C-series models. Stands, speaker output and exact UK model suffixes also vary. Compare the precise product code, included stand arrangement and retailer warranty before treating two C5 listings as interchangeable.
Picture quality, HDR and room suitability
OLED's central advantage is that each pixel produces its own light and can switch off independently. Dark films therefore retain convincing black levels without the halos that can surround subtitles or bright objects on locally dimmed LCD televisions. Viewing angles are broad, motion response is fast and the image has excellent depth in controlled lighting. The C5 is particularly well suited to evening film viewing and rooms where people sit across a wide sofa rather than directly in front of the screen.
It supports Dolby Vision, HDR10 and HLG, but not HDR10+. Dolby Vision support is valuable for compatible streaming and discs, while the absence of HDR10+ matters most to viewers with a library or service that uses that format. Peak brightness is stronger than older mid-range OLEDs but remains scene-, mode- and size-dependent. A Mini LED set such as the TCL C8K or Hisense U8Q can sustain a brighter full-screen image in a sunlit room. The C5 can also reflect windows and lamps, so room layout and curtain control matter more than a single laboratory brightness figure.
Picture modes are important. Vivid modes can exaggerate colour and sharpening, while Filmmaker or Cinema-style modes usually provide a more natural starting point. Upscaling cannot restore detail that is absent from heavily compressed standard-definition broadcasts. Sports viewers may prefer modest motion interpolation, but aggressive settings can create artefacts around fast players and make films look unnaturally smooth.
Gaming, HDMI and smart features
All four HDMI inputs support the modern gaming features that make the C5 unusually flexible for households with several consoles, a gaming PC and an eARC sound system. Current consoles target 4K at up to 120Hz; the C5 can also accept up to 144Hz from a compatible PC. Variable refresh rate, Auto Low Latency Mode, Nvidia G-Sync compatibility and AMD FreeSync support help reduce tearing and latency. The headline 144Hz figure does not mean ordinary television programmes become 144 frames per second, and it requires a suitable graphics card, cable, resolution and game.
One HDMI port is used for eARC when sending lossless or high-bandwidth audio to a soundbar or receiver, but three other high-bandwidth inputs remain available. This is a practical advantage over televisions that offer only two HDMI 2.1-capable sockets. Cable quality matters at long runs, and enabling the relevant deep-colour or gaming input setting may be required before a source exposes every format.
webOS provides the major UK streaming applications, voice and smart-home features, profiles and LG's Game Optimiser. Application availability and interface recommendations can change through software updates. Buyers who dislike prominent content suggestions may still prefer an external streamer. The thin chassis also limits bass and scale, so built-in audio is acceptable for everyday viewing rather than a replacement for a well-chosen soundbar.
OLED care, ownership and verdict
OLED panels can develop image retention or uneven ageing when static logos, scoreboards, news tickers or game interfaces are displayed at high brightness for long repeated periods. Modern compensation cycles, logo dimming and screen-shift features reduce risk but do not make burn-in impossible. Leave panel-care systems enabled, avoid unplugging the television immediately after every use and use sensible brightness for repetitive desktop or channel-logo content. Warranty treatment of image retention should be checked with the retailer rather than assumed.
The C5 is a strong 2026 purchase when discounted far enough below the C6. The newer model improves processing, brightness and high-refresh PC support, but the C5 already covers the needs of current consoles and most home-cinema systems. It is best for buyers wanting excellent dark-room picture quality, wide viewing angles and four capable HDMI inputs. Choose Mini LED instead for sustained bright-room impact, and compare the exact screen size because the smallest C5 models do not reproduce the larger versions' full HDR performance.
