I’ve tested every LG OLED TV you can buy today — here’s what I recommend buying in the Prime Day sale, including 4K bargains that are perfect for the launch of GTA 6

Prime Day has arrived, running from June 23-26, and while LG’s 2026 OLEDs are now available, and there may be some offers around on those, there’s no better time to check out its 2025 lineup. All three of the mainstream 2025 models — the LG G5, LG C5 and LG B5 — featured among the best TVs of 2025, and now that their successors have arrived it’s only a matter of time before these TVs disappear. And with GTA 6 pre-orders live at midnight on June 25, there's no better time for an upgrade.

When it comes to picking which 2025 LG OLED is right for you, the first thing you’ll want to consider is your budget. With these TVs nearing the end of their lifespan, and Prime Day bringing around some excellent offers, this is your best chance to get a step-up model for less. LG’s OLEDs are among the best OLED TVs on the market, and while they’re good value at launch, events like Prime Day are where they shine.

You can read my thoughts below but for me, the highlight deal is the LG C5. The 65-inch C5 is available for $1,199 (was $1,399) at Amazon US, while the 55-inch is available for a record-low £899 (was £1,099) at Amazon UK. There's also the 42-inch C5 for £599 (was £849) at Amazon UK, the perfect bedroom-sized TV.

But, which LG OLED is the best option? While the C5 has the best deal, the B5 or G5 may be what you're looking for. I’ve tested and used all three models throughout the past year, as they serve as our reference screens for 4K Blu-ray testing as part of the Blu-ray Bounty, and as a benchmark for comparisons. Here are my thoughts on each TV below.

LG G5

LG’s 2025 flagship is the LG G5. The most feature-packed model of the lineup, the G5 covers all the bases, delivering on all fronts with some of the best gaming features on the market — 4K 165Hz, full VRR support, HGiG, ALLM and Dolby Vision gaming — with the performance to match. With the Alpha 11 Gen 2 AI Processor, general performance is smooth, with excellent response times that mean scrolling through menus is never a chore.

The G5’s picture quality is superb. It delivers rich, accurate colors regardless of what’s on screen. Whether it’s the staggeringly bright and vivid Wicked, or the more natural colors of The Wild Robot, its color reproduction is truly excellent. As an OLED, it delivers powerful contrast with deep, inky blacks and punchy highlights thanks to its new-found brightness, clocking in at 2,268 nits peak HDR brightness in Filmmaker Mode. It’s much brighter than the C5 and B5, so those who watch TV in bright rooms may want to take note. Textures are crisp and after turning on TruMotion, motion is smooth for sports and fast paced movies. This is easily one of the best-looking TVs you can get.

The G5’s built-in audio is solid, and while it still won’t beat a soundbar, it’s got the best built-in sound of the three LG OLEDs. As it is the flagship model, it comes at a price and while there are some good deals around, it's the priciest of the three.

LG C5

The LG C5 serves as the mid-range model in the 2025 lineup, and strikes a nice middle ground between the flagship G5 and the budget B5. It houses the Alpha 9 Gen 8 AI processor, which delivers smooth performance and has plenty of settings options and picture tools should you want to adjust them, although I found it’s pretty accurate out of the box.

Gamers are well covered here, with 4K 144Hz, full VRR, HGiG, ALLM and Dolby Vision gaming all supported. The C5 delivers razor-sharp performance, and sessions playing Battlefield V were not only smooth, but a ton of fun. Arguably just as good performance-wise as the G5, the C5 still holds the title for best gaming TV.

The C5’s picture quality is excellent. It delivers the deep, accurate black tones you want from an OLED, and with a new peak brightness (it hit a measured 1,180 nits HDR peak brightness in Filmmaker Mode) it delivers punchy highlights to create strong contrast that’s great for movies like The Batman. It also delivers dynamic, vibrant colors that pop on screen, making movies such as The Sound of Music look excellent, and textures are crisp and detail is refined with whatever’s on screen. It doesn’t have the brightness of the step-up G5, but it’s brighter than the B5, again hitting a nice midway point between the two, though it does have a somewhat reflective screen, as you’d expect from a glossy OLED.

While the C5’s built-in speakers are decent enough, it does benefit from a soundbar. Really though, this is the C5’s only downside. It ticks enough of the same boxes as the G5 to please OLED fans, and at a fraction of the price.

LG B5

The LG B5 is the most entry-level OLED in LG’s 2025 lineup, and while it may not have all the premium features and performance of the step-up G5 and C5, it still offers everything an OLED should, and is stacked with features.

In terms of picture quality, the B5 still delivers. It has the strong contrast you would want from an OLED, with deep blacks and solid highlights creating a dynamic range that looks fantastic for high-contrast movies like Alien: Romulus and Dark City. Its colors, while not as bold as its step-up siblings, are still rich and deep, meaning colorful movies like Wicked have plenty of pop on screen. Its motion is also excellent, making it a great TV for fast-paced action and sports. The B5 isn’t the brightest (clocking in at 668 nits peak HDR in Filmmaker), so people with bright rooms may want to take note, but really this is the B5’s only picture-related flaw.

The B5 also makes for an excellent gaming display. It doesn’t support higher refresh rates for PC gaming (144Hz, 165Hz and so on) but it does support 4K 120Hz across four HDMI 2.1 ports. There’s also full VRR support, and Dolby Vision gaming, HGiG and ALLM all feature. It has the same super-low 9.2ms input lag time as the more premium LG OLEDs, with performance feeling razor-sharp even when I was playing intense battle sequences in Battlefield V.

The B5’s main advantage, though, is giving access to OLED for a very affordable price. While it didn’t launch for much cheaper than the C5, the B5 has dropped to some seriously low prices, making it excellent value overall.

And the winner is…

All three of LG’s 2025 OLEDs are great in their own way, and while it does come down to budget, my top pick of these three is the LG C5. It hits the sweet spot between the G5 and B5 in terms of picture quality, features and performance, and will tick the boxes for most people. The G5 may be brighter with bolder picture quality, but comes at a higher cost, while the B5 is on the dimmer side, so the C5 naturally slots itself in the middle.

In terms of Prime Day deals, the C5 also has the best offers, dropping to the most competitive prices of the three. While there are some great deals on the other two models to be had, the C5 is the star of Prime Day. If you’re torn between LG’s 2026 and 2025 TVs for Prime Day, I’d recommend the 2025 models all day, because you can get them for a seriously good price.
