The TV is well appointed on the feature front, starting with a four-pack of high-bandwidth HDMI 2.1 inputs. Each port supports advanced features for next-gen gaming consoles and PCs, including VRR (Variable Refresh Rate) and Freesync Pro to sync the display’s frame rate with your source device, 4K video support at 120 Hz (144 Hz for the smaller models), and ALLM (Auto Low Latency Mode) to engage Samsung’s Gaming Hub when you fire up your console.
Samsung’s gaming interface is among the best available, complete with a separate home screen to adjust settings and engage in console-free cloud gaming from services like Amazon Luna, Nvidia GeForce Now, and Xbox Game Pass. Like most competitors, the TV features an available gaming bar for adjustments on the fly, including the ability to choose from a variety of optimized picture modes. I found the default picture too vivid (or “garish,” as my wife put it), but you can adjust settings within the hub or tinker further from the TV’s main interface.
I’ve had my issues with Samsung’s Tizen OS in the past, although I’ve gotten used to it over time. It’s not as easy to set up as Roku or Google TV, and some settings are oddly organized. For example, there are two different adaptive brightness features engaged by default, in the Intelligent and Eco panes, which might confuse you if you don’t realize they’re changing the TV’s backlight. The picture settings are also inexplicably spread out between multiple panels across the main settings bar, though you can (and should) rearrange them.
Another drawback of all Samsung TVs is their lack of support for Dolby Vision, the most prevalent “dynamic” HDR (High Dynamic Range) format. While nearly all rivals support it, Samsung has stubbornly stuck with its own HDR10+ format, which offers frame-by-frame adjustment for HDR content like Dolby Vision. That said, the TV will default to the best HDR mode supported, so you may not notice much difference.
The QN90C’s onboard sound quality better matches its premium aesthetic, rising above the majority of TVs I’ve tested. While it can get a little sharp in the upper midrange, it’s got surprisingly hefty bass response and adept object tracking for a relatively immersive soundstage. I’m pretty picky about sound, so the fact that the TV speakers sufficed for the majority of my testing, even with multiple action flicks, was impressive.
I also adore Samsung’s teensy, solar-powered remote. It’s not backlit, but it's designed to be navigated by touch, with pop-up volume and channel keys, and other controls intuitively arranged. A responsive control ring resides at the center, while a microphone key at the top calls up Alexa or Samsung’s Bixby voice assistant for smart home controls and search.
(Mostly) Posh Picture
Right out of the box, the QN90C revealed superb image quality marked by excellent contrast and punchy brightness, rich and natural colors, and vivid detail that pops across both 4K and HD content, thanks to Samsung’s fantastic picture processing.
I did the majority of my viewing in the Filmmaker Mode, with only minor adjustments. The Movie mode is also a solid choice that provides more brightness, though to my eyes it looks less natural. You can rev up HDR brightness significantly by changing HDR Tone Mapping from Static to Active under the Picture’s Expert settings, which also enhances shadow detail for better clarity in particularly dark scenes.
