LG C5 OLED evo TV: Features We Love

An All-Rounder That Always Delivers

The C5 continues LG’s winning formula of top-tier OLED picture quality, all the features you could want, and a price that makes it easier to recommend than ever. It’s the sweet spot in LG’s range, outperforming mid-range rivals and getting impressively close to the flagship G-series without the premium price tag.

A Size For Every Setup

The C5 comes in a seriously versatile range of sizes – from a compact 42" perfect for bedrooms and gaming setups, all the way up to a huge 83" for proper home cinema vibes. The stand style varies slightly depending on the size, so it always looks balanced and suits your space.

Great for Gaming

If you’re into gaming, the C5 has you covered. It’s super responsive, supports 4K at 144Hz, and works with all the big features like VRR, G-Sync and FreeSync – so everything feels smooth and looks spot-on. Plus, with 4 full-bandwidth HDMI 2.1 ports, you can hook up your console, sound system easily.

Similar Model Comparison

LG G5

If you love what the C5 offers but want the very best LG has to give, the G5 is a brilliant upgrade. With a brighter Primary RGB Tandem OLED panel, LG’s most advanced processor, and a premium design, its perfect if you want flagship performance for films, sport and gaming.

Sony BRAVIA 8 II

If you’re not set on LG, the Sony BRAVIA 8 II is a serious contender. It steps up to QD-OLED for a picture that’s even better suited to film lovers. It does come in a bit pricier than the C5, but you’re getting a noticeable upgrade in performance which could make it well worth the extra spend.
