144Hz monitor stuck at 60Hz? What to check first

A 144Hz label tells you what a monitor supports under the right conditions. It does not confirm which mode your PC is using. Start by checking the selected refresh rate in Windows. If 144Hz is missing from the available choices, check the monitor's exact model, the input you are using and the connection from the PC.

Also check where the number came from. A game's FPS counter and a display's refresh rate measure different parts of the system. You can have a correctly configured monitor and a game running at 60 FPS, or a fast-running game sent to a display set to 60Hz. NVIDIA's explanation of FPS and Hz makes that distinction.

This guide covers Windows 10 and Windows 11. The monitor examples come from their manufacturers' published manuals.

1. Check the selected refresh rate in Windows

Open Windows display settings and make sure you are inspecting the gaming monitor. With a laptop and an external screen, it is easy to read the settings for the laptop panel instead. Note the resolution and refresh rate before changing either.

On Windows 10, version 20H2 or later, open Settings → System → Display → Advanced display settings. Select the relevant display, then check the refresh-rate choice. Microsoft added this direct control in the October 2020 Update .

On Windows 11, open Settings → System → Display → Advanced display. Select the monitor you want to adjust and look for Choose a refresh rate. Intel documents this route in its 2022 display troubleshooting instructions .

If 144Hz is offered at the resolution you intend to use, select it and check that the picture remains stable. Confirm the change only if the image looks correct. If Windows offers to keep or revert the setting, choose the previous setting if the new one is unusable. ASUS's Windows setup guide describes this confirmation step.

Do not type an unsupported value into a custom-resolution tool just because the box says 144Hz. First establish which resolution and input support that rate.

2. Separate the monitor's Hz from the game's FPS

Refresh rate, in hertz, describes how often the display refreshes. Frame rate, in frames per second, describes how quickly the PC produces frames. ASUS's refresh-rate guide explains why the two rates can differ. Raising the selected refresh rate does not make a demanding game generate 144 frames every second.

For a fixed refresh rate, the interval between refreshes is calculated as 1,000 divided by the rate in hertz:

• 60Hz: about 16.67 milliseconds per refresh.
• 144Hz: about 6.94 milliseconds per refresh.

These are calculated intervals, not measured input lag or a monitor's advertised pixel-response time. They explain the timing difference without promising a particular improvement in a game.

FPS and Hz describe different parts of the process. Refresh intervals are calculated as 1000 divided by Hz; they are not benchmark results. Original Jitsumi diagram.

Use the Windows setting to establish the selected display mode, then check the game's frame-rate counter separately. If Windows already offers and uses 144Hz while the game stays at 60 FPS, skip to the game-settings checks below. Replacing a display cable is a poor first experiment for a frame-rate cap.

3. Read the exact model's supported modes

Find the full model number on the monitor's label or its information menu, then open that model's official manual. Look for a section called Supported operating modes, Preset display modes or Timing table. Match the resolution, refresh rate and input together.

An older ASUS monitor provides a useful example. The VG248QE manual , section 3.4, lists these modes at 1920 × 1080:

For that monitor, a working 1080p HDMI connection at 60Hz fits the documented modes. Buying a more expensive HDMI cable does not add a 144Hz HDMI mode to the monitor's specification. The useful next check is whether the PC can supply one of the supported 144Hz connections.

The similarly named VG248QG is different: its August 2018 manual , section 3.5, explicitly lists 1920 × 1080 at 144Hz over HDMI, subject to compatible graphics hardware. The model suffix matters.

This is why “HDMI only does 60Hz” is unreliable advice. Check the actual devices and supported mode. DisplayPort is not an automatic guarantee either: the PC output and the rest of the connection still need to support what you are asking the monitor to display.

Treat resolution and refresh rate as a pair. “Supports 144Hz” on its own is incomplete information; find the resolution at which it is supported.

4. Try one direct connection before replacing hardware

If the manual lists the mode but Windows does not offer it, simplify the setup. A dock, adapter, switch or converter adds another device whose specifications you must check. Start with a connection you can describe precisely.

The following is an isolation method: it helps narrow the search, but it cannot identify every fault from one result.

1. Record the starting setup. Write down the PC or graphics-card model, output socket, cable, any intermediate device, monitor input, resolution and available refresh rates. Take a photo of the connections if that will help you restore them.
2. Save your work and close the game. Changing display connections can move windows or interrupt a session. Power equipment down before moving or reconnecting it where its manual requires that.
3. Test the monitor directly. If your PC and monitor have compatible ports for the desired mode, connect them with a suitable cable, temporarily bypassing the dock or adapter. Use one external monitor for this check. Do not force a connector or assume a simple plug adapter provides the required signal conversion.
4. Select that input and check Windows again. Use the same intended resolution, then inspect the available refresh rates for that monitor.
5. Compare with the starting setup. Restore the original arrangement when you have recorded the result, or keep the direct connection if it suits your setup and works correctly.

A direct connection removes variables from the test. Each remaining part still has to support the requested display mode. Original Jitsumi diagram.

If 144Hz appears with the direct connection, you have evidence that the simpler route can provide the mode. Check the removed device's specifications, its settings and any cable that changed. The result does not prove that the dock itself is defective, especially if you changed several parts at once.

If 144Hz is still missing, revisit the exact PC output and monitor input. Check whether the monitor manual requires an input setting for the desired mode. Once the hardware specifications agree, check the PC or graphics vendor's driver guidance for your hardware and Windows version. Avoid downloading a driver from a random search result.

If your PC lacks a compatible direct output, skip that experiment. Give the manufacturer or adapter vendor the exact required mode, such as 1920 × 1080 at 144Hz, and ask whether the complete connection supports it. That is a more useful question than asking for a “gaming cable”.

5. If Windows uses 144Hz but the game shows 60 FPS

At this point, inspect the game rather than repeating cable changes. Look for an in-game frame limiter, a refresh-rate option where available, and the selected display. Check whether the game has retained an old setting after you changed Windows.

V-Sync also affects how frame delivery relates to display refresh. NVIDIA's FrameView 1.1 guide , under troubleshooting, identifies both frame caps and V-Sync as reasons a game's FPS may stop at a particular value. Changing those settings is a separate decision from selecting 144Hz in Windows.

Note the existing values, change one setting and compare the same scene. Restore the setting if it does not help. Turning V-Sync off can introduce tearing, so a larger FPS number alone does not settle which setting you will prefer.

There is another wrinkle with variable refresh rate, used by compatible adaptive-sync displays. The display can adjust its refresh timing to the game's frame delivery, within its supported operating range. A changing live refresh reading is therefore different from Windows offering only a fixed 60Hz mode. VESA's explanation of Adaptive-Sync describes how the two rates can be coordinated.

Setting a higher display mode also cannot remove every cause of stutter. If the supported mode is selected and stable, but a game still performs poorly, the remaining investigation concerns the game's performance or settings. Keep that investigation separate so you can tell which change actually helps.

Verify the result before calling it fixed

Return to Windows display settings and confirm the intended monitor, resolution and refresh rate. Where the monitor provides an input-information readout, compare that too, taking variable refresh behaviour into account. Then reopen the game and inspect its own settings and FPS separately.

If you still need help, send the support team your exact model numbers, connection route, selected resolution, available refresh rates and the direct-connection result. Those details make the problem reproducible enough to discuss; “my 144Hz monitor feels slow” leaves too many possibilities open.

The useful finish is a supported display mode that remains stable in your actual setup. Establish that first. You can then judge the game on its own frame rate, without buying hardware to fix the wrong number.
