Xbox Series X FPS settings for smoother 120Hz gameplay start with the display, not a hidden console “turbo” switch. Set a supported resolution, choose 120 Hz in Settings > General > TV & display options, enable VRR when your screen supports it, and let ALLM select the display’s low-latency mode. The console can output up to 120 FPS, but only games with a 120-FPS mode can render at that rate. Your TV or monitor, its exact HDMI port, firmware, and any AV receiver in the signal path determine which combinations are actually available.
What are the best Xbox Series X FPS settings for 120Hz play?
Use the highest resolution and refresh-rate combination your display explicitly supports, then select 120 Hz on the Xbox. For a compatible TV or monitor, the practical baseline is:
As an Amazon Associate I earn from qualifying purchases.
| Setting | Recommended choice | Why it matters |
|---|---|---|
| Resolution | The display’s supported target, such as 4K when 4K/120 Hz is confirmed | The screen determines which resolution and refresh-rate combinations are offered. |
| Refresh rate | 120 Hz, when available at the selected resolution | Allows compatible games to present frames at up to 120 FPS. |
| Variable refresh rate | Allow Variable Refresh Rate: On, if supported | Matches refresh timing to changing game frame rates and can reduce tearing. |
| ALLM or Game Mode | Automatic on a compatible display; otherwise enable the display’s gaming mode | Reduces display processing that can add latency. |
| HDR and 4K troubleshooting options | Leave enabled unless they cause a specific signal problem | Disabling them is a fallback diagnostic step, not a preferred permanent setup. |
These are capability-dependent settings rather than universal values. Microsoft’s current Series X specification lists support for 120 FPS, ALLM, HDMI VRR, AMD FreeSync and HDMI 2.1, while the Xbox TV guidance stresses that the connected display controls the available modes. Check the exact model manual before assuming that a “120Hz” label means 4K at 120 Hz.
How do I turn on 120Hz on Xbox Series X?
Connect the console directly to a compatible HDMI input, then select 120 Hz in the Xbox display menu. If 120 Hz does not appear, the console is not currently recognizing a supported combination of port, cable path, resolution and display settings.

- Update the display chain. Install current firmware for the TV or monitor and any AV receiver. Xbox has noted that manufacturers have added gaming capabilities through firmware updates.
- Use the correct HDMI port. Some televisions reserve their advanced bandwidth or gaming features for one or two numbered inputs. Read the display manual and connect the Series X to the port specified for 4K/120 Hz or HDMI 2.1.
- Bypass or verify an AV receiver. If the console runs through a receiver or soundbar, both the console-to-receiver and receiver-to-display links must pass the desired resolution and refresh rate. Connect directly to the TV temporarily if you are diagnosing a missing option.
- Open the Xbox display menu. Go to Settings > General > TV & display options. Choose a supported resolution, then open Refresh rate and select 120 Hz if it is offered.
- Inspect 4K TV details. Select 4K TV details on that screen. The page shows which capabilities Xbox recognizes from the current connection.
- Confirm in the game. Open the game’s graphics or video options and select its performance, high-frame-rate or 120-FPS mode when provided. A 120-Hz console output does not force a game that is capped at 30 or 60 FPS to render more frames.
Xbox’s published menu labels date from earlier console software and may move slightly after updates. If a label differs, look for the same controls under the TV and display section rather than treating a changed wording as a hardware fault.
Does setting Xbox to 120Hz make every game run at 120 FPS?
No. The Series X specification says “up to 120 FPS”; the game determines its frame-rate target and whether it offers a 120-FPS mode. The 120-Hz setting tells the output link and display to operate at that refresh rate, but it cannot add a performance mode that the game does not include.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Many games expose a choice between a visual-quality mode and a performance or high-frame-rate mode. Use the in-game description to understand the trade-off: a performance mode may reduce resolution, effects or other visual settings to maintain a higher frame rate. Do not infer a game’s actual FPS from the console menu alone; consult the title’s own video options and developer documentation when available.
A 120-Hz display can still be useful for a 60-FPS game because each frame can be presented on a regular, evenly timed schedule, but the game remains a 60-FPS title. It also leaves the display configured for games that do support 120 FPS without repeatedly changing the console setting.
What is the difference between 120Hz and 120 FPS?
Hertz (Hz) is the display’s refresh rate: how often it can refresh each second. Frames per second (FPS) is the rate at which the game produces new images. A 120-Hz screen can refresh 120 times per second, but a game rendering 60 FPS still supplies only 60 new frames.
The two rates must also be supported together at the chosen resolution. A display may advertise 120 Hz at 1080p or 1440p while limiting HDMI input to 60 Hz at 4K. That is why the HDMI port specification and the Xbox 4K TV details page matter more than a generic product headline.
Do these 3 things before closing this tab:
1Repair Windows errors before they cause bigger problems2Scan for outdated or missing drivers - takes under a minute3Clear out junk files and repair common Windows errorsHow do ALLM and Game Mode reduce input lag?
ALLM (Automatic Low Latency Mode) lets the console request the display’s low-latency preset. Xbox describes the behavior this way: “Xbox Series X invokes Automatic Low Latency Mode (ALLM) on capable TVs to automatically enable Game Mode, removing any work previously required of gamers.” The display must support ALLM, and its HDMI or gaming settings may need the feature enabled.

On a compatible TV, look for a status message such as Game Mode, Instant Game Response or Low Latency when a game starts. Names vary by manufacturer, so use the display’s manual rather than assuming that ALLM is active because the console is set to 120 Hz. If the screen lacks ALLM, select its gaming or low-latency picture mode manually. That mode can reduce image-processing delay, but it may change picture quality, motion processing or brightness.
Xbox’s latency explanation also discusses HDMI 2.1 reducing the cited transmission time from 16.6 ms to 8.3 ms for the relevant signal interval. Those are Xbox-published transmission figures, not a guarantee of total controller-to-screen input lag. Controller processing, game engine timing, display processing and any receiver remain part of the complete path.
Should I enable VRR on Xbox Series X?
Enable Allow Variable Refresh Rate when the display supports Xbox-compatible VRR. VRR lets the screen adjust its refresh timing to the game’s changing frame rate, which can reduce tearing and make uneven performance look smoother.
Crashes, No Sound, or Screen Glitches?

The option may be unavailable when the display, HDMI port or receiver does not report compatible support.
VRR is not a substitute for a game’s performance mode and does not turn a 30-FPS game into a 120-FPS game. It is most useful when frame rate moves within the display’s supported VRR range. Because compatibility is model-specific, treat the display manual and Xbox’s recognized-capabilities screen as the authority.
What should I do if VRR causes flicker or visual corruption?
Disable Allow Variable Refresh Rate temporarily and check whether the artifact disappears. Xbox’s troubleshooting guidance specifically recommends turning VRR off when it causes visual corruption; this is a problem-specific fallback, not a universal recommendation.
If you prefer VRR over a 120-Hz output mode and encounter a conflict, Xbox also notes that switching the refresh rate to 60 Hz can address certain cases. Test one change at a time, restart the game, and record which combination is stable. A different HDMI port, display firmware update or receiver bypass may resolve the issue without permanently abandoning VRR.

Why can’t I select 120Hz on Xbox Series X?
The usual cause is that one part of the signal chain does not support 120 Hz at the selected resolution. Work through these checks in order:
- Check the port, not just the TV model. Advanced HDMI features may be limited to a particular input. Confirm that the exact port used by Xbox supports the desired mode.
- Try a lower resolution as a diagnostic. If 120 Hz appears at 1080p or 1440p but not 4K, the display’s bandwidth or mode table may limit 4K to 60 Hz.
- Update firmware. Update the TV or monitor and receiver before drawing conclusions from an older compatibility table.
- Remove the receiver from the path. A receiver can limit passthrough even when both the console and TV independently support 4K/120 Hz.
- Inspect 4K TV details. The Xbox page reports what the current connection actually negotiates, which is more useful than a retailer’s broad “120Hz” description.
- Check the cable path. Series X includes an Ultra High Speed HDMI cable. Replace it only if it is missing or damaged, or if you need an additional cable for a receiver setup; a new cable cannot make a non-compatible HDMI port support 120 Hz.
Some monitors provide the desired resolution and refresh rate through DisplayPort but not through HDMI. Xbox Series X outputs over HDMI, so the monitor’s HDMI input—not its DisplayPort specification—must support the mode.
Which HDMI cable and receiver setup should I use?
Use the included Ultra High Speed HDMI cable for a direct console-to-display connection unless it is missing or damaged. Xbox states that one is included with every Series X. If your receiver sits between the console and screen, use cables and receiver inputs/outputs rated for the same resolution and refresh-rate combination, then verify passthrough in the receiver documentation.
A receiver can be the limiting component even when the TV and console both support HDMI 2.1. For the clearest diagnosis, connect Xbox directly to the display, confirm 120 Hz, then reintroduce the receiver and check whether the option remains. If it disappears, the receiver’s passthrough specification or firmware is the likely constraint.

How should I configure HDR, 4K and other video modes?
Leave 4K, HDR10 and Auto HDR enabled when the complete chain handles them correctly. Disable them only as temporary troubleshooting steps when you see blank screens, 4K errors or HDR color problems.
Xbox guidance recommends temporarily disabling Allow 4K for certain blank-screen or 4K-error cases. For HDR color issues, disable HDR10 and/or Auto HDR, then restore the features one at a time after identifying the failing link. These changes can reduce image quality or remove HDR, so they are diagnostic actions rather than “best FPS settings.”
When testing, change one variable at a time: first the cable or port, then receiver bypass, then resolution, refresh rate and video-mode toggles. This preserves a clear cause-and-effect trail and prevents a temporary workaround from becoming a permanent compromise.

How do I minimize input lag beyond the Xbox menu?
Use the display’s low-latency or Game Mode preset, keep ALLM enabled when supported, and avoid unnecessary processing features such as motion interpolation if the display manual says they add delay. Connect Xbox directly to the display while diagnosing latency, and ensure the game itself is in its performance or high-frame-rate mode when that option exists.

Outbyte PC Repair FREERepair Windows errors before they cause bigger problemsFix Now →Outbyte Driver Updater FREEScan for outdated or missing drivers - takes under a minuteDriver Scan →Remember that “lower input lag” is a system outcome, not a single Xbox number. The Xbox settings can request a faster display path, but total latency also depends on the game’s frame time, controller-to-console communication, display processing, receiver passthrough and the display’s own response behavior. The Xbox HDMI figures describe signal transmission intervals, not an end-to-end measurement for every setup.
What is the best setup for a 4K/120Hz television?
For 4K/120Hz, use a television input explicitly documented for 4K at 120 Hz, current TV firmware, the included Ultra High Speed HDMI cable and a direct connection or fully compatible receiver path. Set the Xbox resolution to 4K, select 120 Hz, confirm the capability in 4K TV details, and enable VRR and ALLM when the television supports them.
If the TV offers 120 Hz only at a lower resolution, choose between sharper 4K at 60 Hz and the higher-refresh mode according to the game and your priorities. The correct choice is the one the display documents and the Xbox recognizes; forcing an unsupported combination can produce a blank screen or repeated signal dropouts.
What is the best setup for a 120Hz gaming monitor?
Verify that the monitor’s HDMI input supports the desired refresh rate and resolution. A monitor’s DisplayPort capability does not transfer to Xbox, which uses HDMI. After connecting, select the supported resolution and 120 Hz in Xbox settings, then check whether VRR is exposed under Video modes.
Monitors often label inputs and refresh modes more precisely than televisions, but the same rule applies: 120 Hz at 1080p or 1440p does not prove 4K/120 Hz support. If the monitor has multiple HDMI inputs, consult its manual for the one with the required bandwidth.

What should I remember about Xbox Series X FPS settings?
The highest-value setting is the one your entire chain can sustain: a compatible game, display port, resolution, refresh rate, firmware and receiver path. Set 120 Hz when the option is genuinely supported, enable VRR and ALLM where available, and treat 60-Hz, HDR or VRR changes as targeted troubleshooting rather than universal “optimal” values.
For the technical background, see Xbox’s latency explanation, the current Series X specifications, and Xbox’s technology glossary. These sources describe the console’s capabilities; your display’s manual determines which of them are usable in your particular setup.
Frequently Asked Questions
Will a 120Hz TV make 60-FPS games look like 120 FPS?
No. The TV can refresh at 120Hz, but a 60-FPS game still generates 60 new frames per second. The higher refresh setting mainly prepares the display for titles that include a 120-FPS mode and can provide consistent timing for lower frame rates.
Do I need to buy a new HDMI cable for Xbox Series X 120Hz?
Usually not: Xbox includes an Ultra High Speed HDMI cable with Series X. Consider a replacement only when the supplied cable is missing or damaged, or when an additional cable is required for a compatible receiver path.
Can Xbox Series X use a monitor’s DisplayPort 120Hz mode?
The console outputs through HDMI, so the monitor’s HDMI input must support the required resolution and refresh rate. A DisplayPort-only 120Hz specification does not establish Xbox compatibility.
Why does my TV leave Game Mode off even though Xbox supports ALLM?
ALLM requires support from the TV and the specific HDMI input, and some displays require a gaming or HDMI control option to be enabled. Check the TV’s status indicator and manual, then enable Game Mode manually if ALLM is unavailable.
What should I do if 4K/120Hz works directly but not through my receiver?
The receiver or one of its HDMI links may not support the required passthrough mode. Verify the receiver’s input and output specifications and firmware, or keep the console connected directly to the TV while routing audio separately if your equipment allows it.
