Select the real rate
Open Settings, System, Display, Advanced display, select the correct monitor, and choose its supported refresh rate.
Your 144Hz monitor may still be running at 60Hz.
Buying a high-refresh display does not guarantee that Windows is using its fastest supported mode. Confirm the selected display, resolution, cable path, monitor menu, graphics settings, and an actual refresh-rate reading before replacing hardware.
Check every connection
The GPU port, cable or adapter, monitor input, resolution, and color mode must all support the target combination.
Measure the result
Use Advanced display, the monitor information menu, or a trusted frame-rate test. Do not judge refresh rate from a still desktop.
Step 1: select the correct display in Windows
- Open Advanced display. Go to Start, Settings, System, Display, then Advanced display.
- Choose the gaming monitor. Multi-monitor systems can show a different panel than the one you intend to change.
- Select the target refresh rate. Choose 120Hz, 144Hz, 165Hz, 240Hz, or another mode only when Windows lists it for that display.
- Recheck resolution. Microsoft notes that some rate choices require a different resolution. Keep the monitor's recommended resolution unless its documentation says otherwise.
- Confirm the change. Return to Advanced display and verify that the active mode reports the rate you selected.
Step 2: find why the faster option is missing
- Monitor menu: some displays require a performance, overclock, DisplayPort, or HDMI compatibility mode before the fastest rate appears. Use the manual for the exact model.
- Cable and adapter: connect the display directly to the graphics card when possible. A dock, converter, capture device, older cable, or motherboard port can limit the available signal.
- Resolution and color mode: the maximum rate can change with resolution, bit depth, chroma mode, and HDR. Test the monitor's documented native combination first.
- Graphics driver: use the official driver source for the installed NVIDIA, AMD, or Intel GPU. Restart after a driver or display-path change.
- Duplicate mode: mirroring displays with different capabilities can restrict the shared mode. Test the gaming display by itself or in Extend mode.
- Laptop routing: USB-C, HDMI, and dock outputs may connect through different graphics or bandwidth paths. Check the laptop and dock specifications together.
Step 3: enable variable refresh rate separately
A fixed refresh rate and variable refresh rate are related but separate settings. First confirm the display is running at the intended maximum rate. Then enable Adaptive-Sync or FreeSync in the monitor menu when supported and configure the matching GPU feature. NVIDIA documents G-SYNC under Display, Set up G-SYNC, and provides an on-screen indicator for verification.
Keep the game inside the display's supported range and test one change at a time. Screen tearing, frame-time stutter, network lag, and a 60Hz desktop setting are different symptoms and need different evidence.
