TVs and monitors · LG
Owners keep the B4 in game rooms and bedrooms for its picture quality and deep blacks, and several bought it at a price they considered a real bargain.
Picture quality gets clear praise. One owner who moved from an IPS gaming monitor to the B4 for a PS5 called the image and the blacks excellent, and said games felt smoother than before.
Burn-in is a clear concern. One owner showed retention after eight months of use without the OLED care features, though they said it looks milder in person. Another said worry about burn-in, plus the refresh routines, took the shine off long sessions.
The LG B4 is LG's lowest-priced OLED TV line from 2024. It is a 4K smart TV for people who want deep blacks and smooth motion for films and games without paying for LG's higher OLED lines.

From the maker's spec page, checked October 5, 2026. A blank row means the maker does not state it.
OLED means each pixel makes its own light, so black areas are truly black. 120Hz with four HDMI 2.1 ports means a PS5, Xbox Series X or gaming PC can run at up to 120 frames per second, and all four ports support it. Dolby Vision makes films and shows that support it look brighter and more detailed. The 48-inch size can work as a large desk monitor.
Pick up to three. You get a page with just those, side by side, on the subjects owners raised.
The picture is still what people talk about months in. Owners point to the black levels, and those who game on it are positive about how it plays. One owner runs it at half brightness in a dark game room and rates it above the more expensive C1 in their living room. The price also keeps coming up as a reason they are pleased: owners describe deep discounts, and one liked their deal enough to buy a second set for a parent.
Brightness is where owners are divided. Some find it more than bright enough with the right content. Others note that the B4's strengths shrink as the room gets brighter, and HDR brightness draws mixed views too. Owners mostly sort out cleaning without trouble: one cleared a stubborn smear with a fresh microfiber cloth and distilled water. On motion, one owner found it choppy next to a mini LED set, but too few owners raised motion to call it either way.
Day to day, most owners describe a set that keeps doing its job, and overall satisfaction is positive. The problems that do come up involve the panel. Faulty panels are a clear concern, and so is LG's support when that happens. One owner who bought direct from LG with a five-year warranty did get a C5 as a replacement for a faulty B4, but only after more than a month of back and forth. Others in the support theme were less happy with how LG handled them.
Long-term accounts are thin. This is a recent model, and most comments come from people in their first year or so with it. The burn-in reports so far are early ones, and there is not yet enough multi-year ownership to say how the panel holds up over time.
From 2 owner accounts that said how long they have had it. Own one? Add how long yours has lasted.
Counted from the owners who raised each subject, not from everyone. A subject is judged once at least 4 owners raise it.
90 more subjects came up from fewer than 4 owners each, which is not enough for a fair reading. To see how it stacks up, compare it with another machine.
The same owner, asked again at each point. Fills in as owners answer.
Two questions: how long you have had it, and anything you would like to say about it. Then we ask again as it ages. This helps our mission.

Among the 2 owner accounts here that gave a duration, 1 described a failure. Parts named most: panel.
Before you buy one used, ask the seller: how old it is, whether it was ever repaired and by whom, and whether any of the parts above have been replaced. Ask to see it run. A receipt tells you the warranty start date; most makers honour the term only for the first owner.
Counted from public accounts by people who said they own it, and summarised by Still Kicks in its own words. Not a manufacturer claim, a lab test or an estimate.
