Owners keep the QN90D as a big-screen Mini LED set for well lit living rooms, and most who wrote in are happy with it, though a few who also own OLED prefer OLED.
Most owners who gave an overall verdict are happy with it. That includes people who bought it at 75 and 86 inches, and one who moved up from a Sony that was a few years old.
Too few owners have commented on picture quality to call it either way. The one negative account came from an owner who switched to an OLED and found it clearly better, though they couldn't say exactly what they disliked about the QN90D.
The Samsung QN90D is a 4K TV from Samsung's 2024 Neo QLED range. It uses a Mini LED backlight and quantum dot color. It suits people who want a bright TV for a sunny living room, and it also works well for console and PC gaming.

From the maker's spec page, checked October 8, 2026. A blank row means the maker does not state it.
4K means the picture is sharp even on the 85-inch and 98-inch sizes. The 144Hz support means a PC or gaming console can show very smooth motion. All four HDMI ports handle this, so you don't have to pick a special port. eARC lets you send full-quality sound to a soundbar. The anti-reflection screen helps in bright rooms. HDR10+ is supported, but Samsung does not list Dolby Vision.
Newer model
QN90F replaces this one. The 2025 QN90F uses Samsung's newer NQ4 AI Gen3 processor. It adds a "Glare-Free" screen, which cuts reflections more than the QN90D's anti-reflection screen. Its Motion Xcelerator goes up to 165Hz, compared with 144Hz, and the size range now runs from 43 to 115 inches.
Pick up to three. You get a page with just those, side by side, on the subjects owners raised.
The owners who are happy with it mostly bought big screens, at 75, 85 and 86 inches, and one says it suits a well lit living room. An owner who has just bought one says the higher-end Mini LED sets like this one give very good picture quality and fairly deep blacks.
The main adjustment is brightness. When someone found the set too harsh, an owner pointed them to Eye Comfort mode and the brightness setting and said the fix lies in the settings. The unhappy owners both measure it against OLED: one says an older LG CX beats it, and another left it for a Samsung S90F and is much happier.
One owner points out that Mini LED carries very little risk of burn-in, which is the usual long-term worry with OLED. None of the comments here describe anything failing or needing repair.
The long-term accounts are thin. Several of these owners say they only just bought the set, and nobody describes years of use, so this page can't yet say how the QN90D holds up over time.
From 0 owner accounts that said how long they have had it. Own one? Add how long yours has lasted.
Nothing has a clear majority against it yet. Counted from the owners who raised each subject, not from everyone. A subject is judged once at least 4 owners raise it.
20 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.

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.
