Community Reviews

This 48 inch LG B5 OLED stands out as a strong gaming and bedroom or desk display, with 120 hertz support, four HDMI 2.1 ports, Dolby Vision, and clear text for PC use. The OLED picture gets praised for its big jump in image quality, and the set is described as bright enough for dark rooms with excellent response time and no burn in concerns. Bright living rooms are the main weak spot, since brightness and reflection handling trail Samsung's S90F. Promo codes are limited, though the price has already dipped to about $500 and open box units have shown up near $450.

  • Shoppers prioritizing picture quality over brightness, because the OLED image is a huge upgrade and Dolby Vision content looks strong.

  • Console players who want a responsive OLED for fast games, because response time is perfect and the panel works well with Xbox and PlayStation at 120Hz.

  • PC gamers using a 48-inch screen as a desk replacement, because 4K text stays clear, 120Hz HDMI 2.1 ports support consoles, and dark-room brightness is sufficient.

  • Bedroom viewers with blinds or drapes, because the panel handles controlled light well and includes Dolby Vision for streaming and discs.

  • Bright living rooms with lots of reflections, because the panel is noticeably dimmer than a Samsung and handles glare less well.

  • Shoppers expecting to use a Best Buy promo code, because this TV is not eligible for that coupon.

  • Main TV buyers who want a large living-room centerpiece, because the 48-inch size works better as a bedroom or desk display.

I bought a Samsung S90F, but it's a bit too big for my room. I think 48" would be better, but how big of a downgrade would this B5 be?

Went to BB yesterday and they had a bunch of these TVs for sale. But I didn't see any in the display area. I think I'll get a 55" TV instead for around the same price like a hisense qd7 the next time it's on sale.

Bought it last month at the same price. Used the pay in 4 PayPal promo for another $110 off. Supposed to get another 10% off from a link through site, time will tell on that one.

In a Bright room the S90f is significantly better due to being able to get brighter / better reflection handling.

I suspect a bedroom has blinds / drapes to control how much light can get in the room. If so, the B5 will do very well and has Dolby vision unlike the Samsung. LG doesnt have HDR10+ but it isn't implemented nearly as much as Dolby vision.

Dolby Vision is prevalent on Netflix, Disney+, Apple TV+, and 4K Blu-rays. HDR10+ is adopted by Amazon prime.

It's not as bright as the Samsung, and it has Dolby Vision, which the Samsung does not - that's the main difference. It'll be like 20% less bright.

It's been as low as $500 this year. I bet by this time this year you will see a few $400 ones on sale. Somehow TVs are the one thing that manage to get cheaper and cheaper.
