There is no universal “4K HDR 120Hz” switch. To get all three features, the television, console, game, HDMI port, cable, firmware, and any equipment between them must support the same signal. The usual setup is to connect the console directly to a full-bandwidth HDMI 2.1 input, select the TV’s enhanced signal format, enable Game Mode and VRR, and then choose the matching output options on the console.
Menu labels differ by TV model and region. A port marked 4K 120Hz, 4K 120Hz/8K, VRR, or a gaming symbol is the best starting point, but the owner’s manual remains the authority for a particular set.
What the HDMI settings actually do
Modern TVs often ship with their HDMI inputs in a compatibility mode intended to work with older devices. That mode may limit bandwidth, disable advanced HDR formats, or hide 4K at 120Hz and variable refresh rate (VRR). An enhanced, high-bandwidth, or HDMI 2.1 mode tells the input to accept the larger signal.
These controls solve different problems:
| TV control | Purpose | What it may unlock |
|---|---|---|
| Enhanced/high-bandwidth HDMI format | Allows the selected input to use the port’s full data rate | 4K at 120Hz, HDR, 10-bit color, and VRR, where the model supports them |
| Game Mode | Uses a lower-latency picture path | Reduced input delay; on some Samsung models, 4K at 120Hz, VRR, and ALLM |
| VRR or FreeSync/G-SYNC control | Matches the panel refresh to changing game frame rates | Smoother motion and fewer tears within the TV’s supported VRR range |
| HDR control | Allows HDR metadata and the appropriate picture mode | HDR output when the TV and source both support it |
Turning on an enhanced input does not create capabilities the hardware lacks. A 60Hz panel cannot become a 120Hz panel through a menu, and a TV with only one full-bandwidth input cannot provide HDMI 2.1 performance on every socket.

Check compatibility before changing menus
Television
Look up the exact model number, not just the series name. Confirm whether it has a 120Hz panel, 4K 120Hz input support, VRR, HDR, and which HDMI sockets carry the highest bandwidth. Some sets provide these features on one or two inputs only. Also check whether a firmware update is required and whether the advertised modes apply to your region or edition.
Console and game
PlayStation states that the PS5 supports the HDMI 2.1 specification and 4K 120Hz video output, but the complete home-entertainment chain still determines what appears on screen. A game must also include a 120Hz mode to render at that rate; the console menu alone cannot make a 30fps or 60fps title run at 120fps. Xbox provides a display diagnostic page that identifies which 4K and high-refresh features the connected TV reports.
Other equipment
An AV receiver, soundbar, capture device, or HDMI switch can restrict the signal even when the TV and console are capable. For the first setup, remove those devices and connect the console straight to the television. Reintroduce them only after the direct connection works, checking each device’s HDMI 2.1 bandwidth specification.

Find the full-bandwidth input
Inspect the labels beside the TV sockets or in its specification sheet. Preferred markings include 4K 120Hz, 4K 120Hz/8K, VRR, HDMI 2.1, or a game-controller icon. Do not assume that the highest-numbered port is the fastest; manufacturers place their capable inputs in different positions.
Choose a suitable cable
Use the cable supplied with the console when it is identified as suitable for 4K 120Hz, or use an Ultra High Speed HDMI cable rated for that signal. A cable that works for 4K at 60Hz may fail when 120Hz, HDR, and VRR are combined. Keep the cable direct during diagnosis and avoid unverified extenders or adapters.

Enable the TV’s enhanced HDMI format
Open the settings for the specific HDMI input used by the console. The path and wording vary, but the control is usually under Inputs, External Inputs, HDMI signal format, or a similar heading. Select the option that indicates enhanced, high bandwidth, 4K 120Hz, or HDMI 2.1 operation.
Common names by manufacturer
| Manufacturer example | Enhanced-input label reported for compatible models |
|---|---|
| Sony | Enhanced format; Enhanced format (VRR); Enhanced format (4K120) |
| LG | HDMI Ultra HD Deep Color |
| Samsung | HDMI UHD Color |
| Panasonic | HDMI HDR Setting |
| Philips | HDMI mode |
| Vizio | HDMI Mode 2.1 |
These are examples, not universal menu paths. A model may expose separate choices for 4K 120Hz and VRR, or combine them in one enhanced setting. If enabling the option causes a blank screen, wait for the input to recover, switch back to the previous mode, and verify the cable and port before trying again.
Turn on Game Mode and VRR
Enable Game Mode for the console input when the TV offers it. This normally bypasses image processing that adds latency. Then enable VRR, or the manufacturer’s FreeSync or G-SYNC option, if the TV and console support it. Some sets enable Auto Low Latency Mode (ALLM) automatically when Game Mode is selected; others expose ALLM as a separate toggle.
VRR is not the same as a fixed 120Hz output. The TV still needs a supported VRR range, and the game’s frame rate must fall inside that range for the feature to operate. Consult the model’s manual for the exact range and supported VRR standards.
Enable HDR on the input when required
Many TVs detect HDR automatically after the source begins sending it. Others have a separate HDR, HDMI HDR, or input-format control. Enable that option for the console input if the picture remains in SDR. Sony notes that not all 4K TVs support HDR, so a 4K resolution label alone is not proof of HDR capability.

PS5 settings for 4K, HDR, VRR, and 120Hz
After connecting the PS5 directly to the capable HDMI input and selecting the TV’s enhanced format, configure the console:
- Open Settings on the PS5.
- Choose Screen and Video, then Video Output.
- Set Resolution to Automatic or 2160p.
- Set 120 Hz Output to Automatic.
- Set VRR to enabled when the TV supports it.
- Enable HDR in the same video-output area, using the available automatic or supported setting.
Return to the PS5 video-output information screen to see what the TV reports. If 120Hz is available only in a particular game, select that game’s performance or 120Hz mode as well. A title that does not offer a high-refresh mode will continue to use its own frame-rate target.
Xbox settings for 4K, HDR, VRR, and 120Hz
- Open Settings on the Xbox.
- Go to General, then TV & display options.
- Choose the highest resolution reported by the television, normally 4K UHD on a compatible set.
- Set the refresh-rate option to 120Hz when it is offered.
- Open 4K TV details to review which 4K, HDR, and 120Hz capabilities the Xbox detects.
- Open Video modes and enable the available HDR and variable-refresh options.
If the 120Hz choice is missing, the Xbox is reporting a limitation somewhere in the chain. Check the input selected on the TV and the cable first, then test the console directly on another labeled high-bandwidth port.
How to verify that each feature is active
Verify 4K resolution
Use the console’s video-output information page and the TV’s on-screen signal display, if available. The reported signal should show 3840×2160 or a 2160p equivalent. A TV showing a 4K picture from its own streaming apps does not prove that the console input accepts 4K 120Hz.
Verify 120Hz
The console menu should offer 120Hz, and a compatible game should expose a 120Hz or performance mode. Some TVs briefly display the incoming refresh rate when a game starts. Check the signal information while the game is running rather than relying only on the TV’s panel specification.

Verify HDR
Start an HDR-enabled game or test clip and confirm that the TV switches to an HDR picture mode or reports HDR in its signal details. Calibrate HDR on the console after the TV recognizes the signal; calibration performed while the input is still SDR will not represent HDR output accurately.
Verify VRR
Use the TV’s VRR status indicator if it has one, or the console’s compatibility information. VRR may engage only while a game is rendering inside the set’s supported range. A static dashboard is not a reliable test because it may run at a fixed refresh rate.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Why a console may show only 4K at 60Hz
The console is on a limited input
Many televisions have mixed HDMI capabilities. Move the cable to the socket specifically marked for 120Hz, 8K, VRR, or HDMI 2.1, then select that input before checking the console menu again.
The enhanced format is disabled
In standard mode, the TV may advertise only 4K at 60Hz. Reopen the signal-format setting for the exact input in use and select the enhanced option. On some models, changing this setting restarts the input or temporarily removes the picture.

Connect the console directly to the TV. If 120Hz and VRR appear in that configuration, the intermediary device is the bottleneck. You may need a compatible HDMI 2.1 receiver or a separate audio connection to retain full video bandwidth.
Best Value

The cable cannot carry the combined signal
Replace an older or unidentified cable with the console’s rated cable or an Ultra High Speed HDMI cable. Keep the replacement as short and direct as practical while testing.
Firmware or model support is missing
Install the TV’s current firmware and restart both devices. If the model’s documentation lists only 4K at 60Hz, no setting can add 120Hz. Firmware can correct negotiation problems, but it cannot add a missing physical input or panel capability.
The game does not offer 120Hz
Even with a successful 120Hz connection, individual games choose their own output modes. Check the game’s graphics settings for a 120Hz, performance, or high-frame-rate option.

Troubleshooting a blank screen, flicker, or unstable VRR
- Blank screen after enabling enhanced mode: Wait for the input timeout, then select the previous HDMI mode and test another certified cable. Re-enable the enhanced option only after confirming the port and source settings.
- HDR works but 120Hz does not: Confirm that the game supports 120Hz and that the console refresh-rate setting is automatic or 120Hz. HDR alone does not indicate full HDMI bandwidth.
- 120Hz works but VRR is unavailable: Turn on the TV’s VRR or compatible adaptive-sync control, enable VRR in the console menu, and check whether the model supports the console’s VRR standard and required range.
- VRR causes flicker: Update the TV firmware, test another VRR-enabled game, and compare behavior with VRR temporarily disabled. Some panels behave differently at the edges of their supported range.
- Picture drops out intermittently: Remove switches and receivers, reseat both HDMI plugs, and test the supplied or certified Ultra High Speed cable on the TV’s designated high-bandwidth port.
How to compare TVs for console HDMI use
When choosing between models, compare the specifications that affect the complete signal path rather than looking only for an “HDMI 2.1” badge.
| Comparison point | Questions to answer |
|---|---|
| Full-bandwidth HDMI ports | How many support the required bandwidth, and where are they located? |
| 4K 120Hz support | Does the input accept 4K at 120Hz, and is that support available on every HDMI socket? |
| VRR | Which standards are supported, what is the operating range, and is a separate toggle required? |
| HDR formats | Which HDR formats does the model accept from an external HDMI source? |
| Game Mode and ALLM | Does Game Mode reduce processing, and can ALLM switch it automatically? |
| Enhanced-input control | Must an enhanced, deep-color, or HDMI 2.1 mode be enabled manually? |
Exact menu names and supported combinations vary by model and region. A specification sheet that lists features separately may not guarantee that every feature operates simultaneously, so check the manual’s supported-signal table.
A reliable setup sequence
- Update the TV and console firmware.
- Identify the TV input labeled for 4K 120Hz, 8K, VRR, or HDMI 2.1.
- Connect the console directly with its supplied or certified Ultra High Speed HDMI cable.
- Select the TV’s enhanced or high-bandwidth input format.
- Enable Game Mode, VRR, and any required HDR input control.
- Set the PS5 or Xbox resolution, refresh rate, HDR, and VRR options.
- Check the console’s capability page and the TV’s signal information.
- Test an actual 120Hz-capable game before reconnecting a receiver, switch, or soundbar.
This order isolates the variables that most often prevent the desired signal. If the direct connection succeeds but the complete setup fails, add intermediary equipment back one device at a time to identify the limiting component.
