Yes, but usually not natively. Xbox Series S can output a 4K signal to a 4K television by upscaling game frames rendered at lower resolutions. Microsoft designed the console primarily for 1440p gaming, with a target of up to 120 frames per second when a game and display support that mode.
Native 4K gaming means the game itself renders gameplay at 3840 × 2160 pixels. That is the graphics target associated with Xbox Series X, not the standard Series S target. A Series S can still look very good on a 4K TV, but the TV’s 4K panel does not change the resolution at which the console renders each game.
What “4K” means on Xbox Series S
There are two different resolutions involved: the resolution produced by the game engine and the resolution sent to your television.

Native 4K rendering
Native 4K gameplay is rendered at 3840 × 2160 pixels. Microsoft’s publishing guidance uses “Available in 4K” only when a reasonable amount of gameplay is rendered at that resolution. A 4K menu, video, or cutscene by itself does not qualify a game for that label.

Upscaled 4K output
With upscaling, the console first renders a frame at a lower resolution—often 1440p or 1080p, with the exact behavior set by the game—and then converts that frame into a 4K output signal. Your television receives a 3840 × 2160 signal, but the original game image contained fewer rendered pixels. Upscaling can make that image look cleaner on a 4K screen, but it is not the same as native 4K detail.
Microsoft describes the Series S in exactly those terms: it is designed for 1440p gaming “with the ability to upscale to 4K.” The wording identifies 1440p as the design target and 4K upscaling as an output capability.
Series S resolution and frame-rate targets
Microsoft’s current Series S specification lists 1440p gaming and performance of up to 120 FPS. The 120-FPS figure is a ceiling for supported content, not a guarantee that every game reaches it. The title must include a 120-FPS mode, and the display must accept the required refresh rate.
A September 2020 Xbox Series X|S fact sheet described the Series S target as 1440p at 60 frames per second, with support for higher frame rates. That target is useful for understanding the product’s position: Series S prioritizes a balance of sharpness and smooth performance at 1440p rather than making native 4K the default.
Why one game can look different from another
Resolution and frame rate are decisions made per game. Developers allocate the console’s performance budget among resolution, frame rate, lighting, shadows, texture quality, ray tracing, and other effects. A title may offer separate quality and performance modes, use dynamic resolution, or change its behavior after an update.

Microsoft treats native 4K, designed-for-60-plus-FPS, and designed-for-120-FPS as separate capability labels. A game can therefore prioritize a high frame rate at a lower resolution, prioritize image detail at a higher resolution, or switch between modes in its settings. There is no single native-resolution number that describes every Series S game.
Xbox Series S versus Xbox Series X for 4K gaming
The consoles share the Xbox Series generation’s game library, but their graphics targets and physical-media options differ.

Choose Series S when digital ownership, a lower-cost entry point, and 1440p-class gaming fit your priorities. Series X is the more appropriate choice when native 4K rendering, physical discs, or the higher-end graphics target is central to the purchase. Prices and availability vary by retailer and market, so compare the current local listings rather than relying on an old launch price.
How Series S looks on a 4K television
A 4K TV can display the Series S’s upscaled output without any special conversion box. The console sends a compatible 4K signal, and the television displays it at the panel’s native 3840 × 2160 resolution. Whether the picture looks crisp depends on the game’s internal resolution, its reconstruction or upscaling method, anti-aliasing, texture quality, viewing distance, and the TV itself.
At normal sofa distance, a well-tuned 1440p image upscaled to 4K can look sharp. You should not expect the same fine detail, distant-object clarity, or texture definition as a native-4K render from Series X in a comparable quality mode. The difference is easiest to see on a large screen at close viewing distances or in games with highly detailed scenery and text.

What the display and connection can and cannot do
- The Series S specification includes an HDMI 2.1 port, Auto Low Latency Mode, HDMI Variable Refresh Rate, and AMD FreeSync support.
- A 4K television can show the console’s upscaled 4K signal and may enable 4K resolution, HDR, or high-refresh modes supported by both devices.
- A 120-Hz television is required to view 120-FPS output, but the game must also provide a 120-FPS mode.
- An Ultra High Speed HDMI cable can provide the bandwidth required by supported high-resolution and high-refresh signals; it cannot make a lower-resolution game render natively at 4K.
- Buying a more expensive cable or replacing a 1440p game with a 4K TV changes signal delivery or display quality, not the game engine’s internal render resolution.
Setting up Series S with a 4K TV
- Connect the console directly to a compatible HDMI input on the television. Use the cable supplied with the console or an Ultra High Speed HDMI cable when you need the bandwidth for high-refresh features.
- On the Xbox, open Settings, choose General, then open TV & display options. Select the highest resolution and refresh-rate combination that both the console and television report as supported. Menu labels can change slightly with system updates.
- Check the television’s input settings. Some sets reserve their full HDMI bandwidth for a specific input mode, such as Enhanced, Input Signal Plus, or a similarly named setting.
- Enable the display’s game or low-latency mode if you want faster response. Auto Low Latency Mode can switch a compatible television automatically, but the TV must support the feature.
- For smoother motion, enable variable refresh rate on the Xbox and television when both support it. VRR helps the display follow a game’s changing frame rate; it does not raise the game’s resolution.
- Open the individual game’s video settings and select its quality, performance, or 120-FPS mode when available. The console’s global output setting cannot force a title to render at native 4K or 120 FPS.
4K video streaming is not 4K game rendering
Series S can stream 4K video from listed entertainment services, including Disney+, Netflix, Amazon, Hulu, and Microsoft Film & TV, when the service, subscription, title, network connection, and television support the required format. Video playback is a separate workload from real-time game rendering.

The console can decode and output high-resolution video while a demanding game uses a lower internal resolution to maintain its chosen frame rate and effects.
How to tell what a game actually supports
Look for the game’s official Xbox feature labels and in-game graphics options rather than assuming that a 4K television or a 4K output setting means native 4K. Microsoft’s “Available in 4K” designation is intended to mean that gameplay—not merely menus or cinematics—is rendered at 3840 × 2160 for a reasonable portion of the experience.
Useful questions to ask for a specific title
- Does the listing explicitly say “Available in 4K,” or does it only mention 4K video, HDR, or a 4K cinematic?
- Does the game offer separate quality and performance modes?
- Is the 4K claim native, reconstructed, or an output-resolution statement?
- Does a 120-FPS mode reduce resolution or disable ray tracing?
- Has a later patch changed the resolution, frame-rate cap, or graphics options?
These questions matter because two Series S games can use the same console and deliver very different combinations of sharpness, smoothness, and visual effects.

“My TV says 4K, so the game must be native 4K.”
The TV reports the signal it receives, not the resolution at which the game engine created the frame. A Series S can send an upscaled 4K signal from a 1440p or 1080p render.

“The HDMI 2.1 port makes Series S a 4K console.”
HDMI 2.1 provides connection features and bandwidth, including support for compatible high-refresh and variable-refresh signals. It does not increase the console’s graphics-processing budget or alter a game’s internal resolution.
“Every Series S game runs at 1440p and 60 FPS.”
Those figures describe Microsoft’s design target, not a fixed result for every title. Developers may use dynamic resolution, a lower resolution for a performance mode, a higher resolution for a quality mode, or a frame-rate cap below 60 FPS.
“A 120-Hz TV guarantees 120 FPS.”
The display can refresh at 120 Hz, but the game must contain a 120-FPS mode and the console must be configured for a compatible output. Some modes trade resolution or visual effects for speed.
“A Series S can play physical 4K discs.”
Series S is all-digital and has no disc drive. It cannot play physical game discs or UHD Blu-ray discs. Games must be obtained digitally through supported Xbox purchasing and subscription options.
Is Series S the right choice for a 4K setup?
Series S makes sense when the television is already available, the priority is digital gaming, and 1440p-class rendering with occasional 4K upscaling is acceptable. It can use modern display features such as VRR and 120-Hz output when the game and television support them.
Series X is the better fit if your purchase decision depends on native 4K game rendering, physical-disc support, or the greatest graphics headroom in the Xbox Series family. Even then, check the individual game’s modes: native-4K capability is a console target, not a promise that every title always renders at 3840 × 2160.
