Not Recommended For

Watch Out For

- Switching inputs requires holding down a combined input/dashboard button for 3 seconds, which can be slow and sometimes defaults to the home dashboard due to software lag.

- Direct reflections are distracting in bright rooms, making the picture appear washed out.

What Buyers Say
Despite being an 'entry-level' OLED, the LG B5 series is getting a lot of buzz for its gaming performance and picture quality, especially considering its price point. Users on LG's site give it a 4.4 out of 5 stars across 180 reviews, which is pretty solid. The biggest trade-off compared to higher-end models like the C5 is peak brightness, with the B5 hitting around 650 nits HDR in a 10% window, making it less ideal for bright rooms. However, for dark room viewing and gaming, the perfect blacks and 120Hz refresh rate are consistently highlighted as major wins. Some users have pointed out minor annoyances with the AI software's persistent pop-ups and the remote's input switching method.
“Look, if you're not trying to watch TV with the sun blasting through your windows, this B5 OLED is a no-brainer for the price. The picture is insane, especially for gaming, but that AI pop-up every time I turn it on is driving me nuts, and the remote could be better. Still, for movies and games, it's a beast.”
Common Praise
- Perfect black levels and infinite contrast create stunning image depth
- Extremely low input lag (as low as 9ms with Game Optimizer) makes gaming incredibly responsive
- Smooth motion handling with 120Hz refresh rate and 0.1ms response time for fast-paced content

Common Complaints

Ownership Tips

- The 'Game Optimizer' dashboard is genuinely useful for fine-tuning gaming settings quickly.
- While not as bright as the C5, the B5 still offers a significant upgrade in picture quality if you're coming from an older LED TV.

Buying Guide
When you're looking at an OLED TV like this LG B5, you're buying into incredible picture quality where every single pixel lights up independently. This means you get perfect blacks and colors that really pop, making movies and games look amazing. But here's the catch: OLEDs generally aren't as bright as some other TV types, so if your living room is super sunny, you might find yourself battling reflections. Think about where you'll put it and how much light that room gets.
OLED Display
Unlike traditional LED TVs that use a backlight, each of the 8.3 million pixels on an OLED screen lights up on its own. This means when a pixel is black, it's truly off, creating 'perfect black' and infinite contrast, like turning off a light in a dark room versus dimming it.
120Hz Refresh Rate & HDMI 2.1
The 120Hz refresh rate means the screen can update 120 times per second, making fast-moving action look incredibly smooth, especially in sports or video games. HDMI 2.1 ports are essential for this, allowing your gaming console or PC to send those high-frame-rate 4K signals to the TV without bottlenecking, like a super-fast highway for video data.
Alpha 8 AI Processor Gen2
This is the TV's brain. It uses artificial intelligence to analyze what you're watching and listening to, then automatically adjusts the picture and sound settings in real-time. It's like having a smart director and sound engineer tweaking things on the fly to make everything look and sound its best, without you having to dive into menus.
Alternatives
If peak brightness in a very bright room is your top priority, look for TVs with MiniLED backlighting or QD-OLED panels; if you need a lower price point, consider a QLED or high-end LED TV with local dimming.
