can 144hz monitor run at 120hz

You plug in a new 144Hz monitor, boot up your game or console, and head to the display settings expecting buttery smooth motion. Only you don't see 120Hz anywhere in the list. Just 144Hz and 60Hz.

Maybe your screen goes black the second you try to switch. It's frustrating, and it makes you wonder: can 144Hz monitor run at 120Hz?

The short answer is yes, absolutely. A 144Hz panel is perfectly capable of running at 120Hz. In fact, every 144Hz monitor we've researched supports lower refresh rates natively, including 120Hz, 60Hz, and often 100Hz.

The panel itself isn't the problem. The blockers almost always come from something else in the chain: your cable, your graphics card, your console, or the resolution you're trying to push. As of 2026, most modern monitors ship with HDMI 2.0 or DisplayPort 1.4, both of which handle 120Hz easily at standard resolutions.

But there are still plenty of edge cases where things go sideways. Let's walk through exactly what's going on and how to fix it.

Quick Answer

Yes, a 144Hz monitor can run at 120Hz. The panel supports it by design. The issue is usually your cable, your device, or your resolution.

HDMI 1.4 tops out at 1080p 120Hz. HDMI 2.0 hits 1440p 120Hz. DisplayPort 1.2 handles 1440p 144Hz easily.

For 4K 120Hz, you need HDMI 2.1 or DisplayPort 1.4 with DSC. Check your cable first. Then check your device's output settings.

Why Can't I Just Select 120Hz on My 144Hz Monitor?

This is the moment where most people start digging through menus and swearing under their breath. You know the monitor can do it. The specs say it can do it.

But the option just isn't there.

The most common reason is the cable. A lot of monitors ship with an HDMI 1.4 cable in the box, even if the monitor itself supports higher standards. HDMI 1.4 maxes out at 1080p 120Hz.

If you're trying to run 1440p or 4K at 120Hz over that cable, the monitor won't even show the option. It's not a compatibility issue. It's a bandwidth issue.

The cable literally cannot carry that much data per second.

Another big culprit is the device on the other end. Older laptops with integrated graphics sometimes lock refresh rate options in the driver. Consoles like the PlayStation 5 and Xbox Series X need specific settings enabled before they'll output 120Hz.

And some monitors have a quirk where they only show 120Hz as an option when connected over DisplayPort, not HDMI. It depends on how the manufacturer programmed the monitor's EDID, which is basically the digital handshake that tells your device what the monitor can do.

If you're stuck at 60Hz and only see 144Hz and 60Hz as options, you're almost certainly dealing with a bandwidth limitation. The monitor knows it can run at 144Hz, but the signal it's receiving doesn't have enough room to run at 120Hz at the current resolution. So it falls back to 60Hz as the next safe option.

How Refresh Rates Work and Why 144Hz Monitors Support 120Hz Natively

Let's clear up a common misunderstanding. A 144Hz monitor doesn't have two separate panels inside it, one for 144Hz and one for 120Hz. It has a single panel that can refresh anywhere from its minimum to its maximum refresh rate.

Refresh rate is measured in hertz, which simply means cycles per second. A 144Hz monitor refreshes the image 144 times per second. A 120Hz signal tells the monitor to refresh 120 times per second.

Since 120 is lower than 144, the monitor simply waits longer between each refresh cycle. It's no different from your car's speedometer showing 55 mph when it can go 120 mph. The hardware has headroom.

Here's what that looks like in practice. If you send a 120Hz signal to a 144Hz monitor, the monitor's scaler chip receives that signal and tells the panel to refresh at 120Hz instead of 144Hz. The panel itself doesn't care.

It just accepts the timing instructions and adjusts. This is why 120Hz, 100Hz, and even 60Hz all work without any special configuration on most monitors.

There is one exception worth knowing about. Some older or budget 144Hz monitors use scalar chips that only support specific refresh rate presets. You might see 60Hz, 120Hz, and 144Hz as discrete options rather than a continuous range.

That's fine. Those presets still work. The monitor just won't let you pick 100Hz or 85Hz if the scalar wasn't programmed for them.

But 120Hz is almost always included because it's such a common standard for console gaming and video content.

The Real Gatekeepers: Cable, Connection, and Device

If the panel can handle 120Hz without breaking a sweat, why does it sometimes refuse to cooperate? Because there are three gatekeepers between your device and the monitor, and any one of them can block 120Hz entirely.

Cable Bandwidth Limits

This is the single most common problem we see in research and user reports. The cable is the bottleneck. Here's what each cable standard can actually handle at 120Hz.

If you're trying to run 1440p at 120Hz over an HDMI 1.4 cable, it won't work. The monitor might show a black screen or default to 60Hz. Same goes for 4K 120Hz over HDMI 2.0.

The cable simply doesn't have the bandwidth.

The Graphics Card or Console

Your GPU or console also has to be capable of outputting 120Hz at your target resolution. Most modern graphics cards from NVIDIA, AMD, and Intel support 120Hz over DisplayPort and HDMI 2.0 or higher. But older cards, especially integrated graphics on laptops, sometimes cap out at 60Hz over HDMI.

For consoles, the situation is slightly different. The PlayStation 5 and Xbox Series X both support 120Hz output, but only over HDMI 2.1 for 4K 120Hz. If you're using an HDMI 2.0 cable or monitor, they'll cap at 1440p 120Hz or 1080p 120Hz depending on the game.

The Nintendo Switch maxes out at 60Hz regardless of the monitor.

The Monitor's Input Ports

Not all ports on your monitor are created equal. Many 144Hz monitors have one DisplayPort input that supports the full 144Hz, and one or two HDMI inputs that support lower refresh rates. Some monitors only support 120Hz over DisplayPort, not HDMI, even though the HDMI port is labeled as 2.0.

This is a manufacturer decision, not a technical limitation. Check your monitor's manual or specs sheet to see which ports support which refresh rates. If you're plugged into HDMI and can't get 120Hz, try switching to DisplayPort.

It solves the problem more often than you'd think.

How to Set Your 144Hz Monitor to 120Hz (PC, Console, and Mac)

Once you've identified the right cable and port, setting the refresh rate is straightforward. The steps vary slightly depending on your device, but the workflow is the same everywhere. Find the display settings, locate refresh rate, and select 120Hz.

On Windows 10 and 11

Right-click on your desktop and select Display settings. Scroll down to Advanced display. Under Choose a refresh rate, you'll see a dropdown with available options.

Select 120Hz. If you don't see it, click Display adapter properties for Display 1, go to the Monitor tab, and check the Screen refresh rate dropdown there.

If 120Hz still isn't showing up, your cable or GPU likely can't handle it at your current resolution. Try lowering your resolution to 1080p and check again. If 120Hz appears at 1080p but not at 1440p or 4K, you've confirmed a bandwidth bottleneck.

On PlayStation 5

Go to Settings > Screen and Video > Video Output. Set Resolution to Automatic. Then scroll down to 120Hz Output and set it to Automatic.

The console will detect your monitor's capabilities and output 120Hz if the game supports it. You can verify by checking the current refresh rate in the same menu under Video Output Information.

One thing to watch for on PS5: some games only run at 120Hz in performance mode. If you're in a resolution or quality mode, the console might drop to 60Hz even though the monitor supports 120Hz. That's game-specific, not a monitor issue.

On Xbox Series X and S

Go to Settings > General > TV & Display Options > Refresh Rate. Select 120Hz. The console will run a compatibility check and confirm whether your monitor supports 120Hz.

If it fails the check, try switching to 1080p or 1440p in the Resolution dropdown before trying again.

Xbox also has a feature called Allow 120Hz that needs to be enabled in the same menu. If it's grayed out, your monitor isn't reporting 120Hz support over the current connection. That usually points to an HDMI cable or port limitation.

On macOS

Go to System Settings > Displays. Hold the Option key while clicking the Scaled button under Resolution. This reveals additional refresh rate options.

Select 120Hz if it appears. If it doesn't, your Mac might be connected via an adapter that doesn't support higher refresh rates.

Apple's documentation confirms that Macs with Apple Silicon support 120Hz over USB-C or Thunderbolt to DisplayPort cables. HDMI connections on Macs are often limited to 60Hz, especially with third-party adapters.
