Quick Answer

If your monitor is stuck below 1440p 60Hz, the most common causes are an HDMI 1.4 cable or port (which limits 1440p to 30Hz), incorrect Windows display settings, or a GPU that is not outputting at the correct resolution. Switching to DisplayPort or HDMI 2.0+ and setting the resolution manually in Windows Display Settings resolves the issue in most cases.

Reaching 1440p at 60Hz or higher should be straightforward once you have a compatible monitor and GPU, but several easy-to-miss configuration issues can leave you stuck at a lower resolution or refresh rate. Work through the steps below in order to diagnose and fix the problem without guessing.

Check Your Cable and Port First

The cable between your GPU and monitor is the most frequently overlooked bottleneck. HDMI 1.4, which ships in the box with many older monitors and budget TVs, supports 1440p only at 30Hz - not 60Hz. If you are connected via HDMI and your refresh rate is capped at 30Hz despite having a 1440p capable monitor, replacing the cable with an HDMI 2.0 or HDMI 2.1 cable will immediately resolve the issue.

DisplayPort is the safer choice for high-resolution and high-refresh-rate setups. DisplayPort 1.2 supports 1440p at up to 165Hz, while DisplayPort 1.4 handles 1440p at 240Hz and 4K at 144Hz. If your GPU and monitor both have DisplayPort connectors, use DisplayPort - it avoids the bandwidth limitations that HDMI versions introduce and is the standard recommendation for gaming monitors.

Also verify which physical port on your GPU you are using. On Nvidia GPUs, all DisplayPort and HDMI outputs are active simultaneously, but on some AMD cards older than the RX 7000 series, specific ports may share bandwidth. Refer to your GPU''s manual if you are using multiple monitors and experiencing issues on a specific output.

Windows Display Settings Configuration

Even with the correct cable, Windows sometimes defaults to a lower resolution or refresh rate. Right-click the desktop and select Display Settings. Scroll to Resolution and set it to 2560x1440. Then click Advanced Display Settings and verify the Refresh Rate dropdown shows 60Hz or higher - select the correct value if it does not match your monitor''s rated refresh rate.

If 1440p does not appear in the resolution dropdown at all, Windows may not have correctly identified your monitor. Check that your monitor drivers are installed - most modern monitors are plug-and-play, but some require drivers from the manufacturer''s support page, particularly ultrawide or high-refresh-rate panels. Open Device Manager and look under ''Monitors'' to verify the monitor is identified by name rather than showing as a generic display.

GPU driver settings can also override Windows resolution choices. Open NVIDIA Control Panel or AMD Software and navigate to Display > Change Resolution. Ensure 2560x1440 at your target refresh rate is selected here as well - sometimes the display driver and Windows settings conflict.

Monitor OSD and Input Settings

Your monitor''s on-screen display (OSD) menu contains settings that can independently limit resolution or refresh rate. Check the Input Source selection - ensure the monitor is set to the correct physical input (DisplayPort vs HDMI) that matches your cable. Some monitors have separate HDMI ports rated for different bandwidth; HDMI 2.0 and HDMI 2.1 ports may be marked separately on the rear of the panel.

Check the monitor''s refresh rate setting in its OSD if one exists. Some budget 1440p monitors ship with their maximum refresh rate locked in the OSD and require a manual change to enable 144Hz or 165Hz modes.

Frequently Asked Questions

Q: My GPU is brand new - why can''t I get 1440p 60Hz? A: Even with a new GPU, if the cable is HDMI 1.4 or the monitor is connected to a TV''s HDMI 1.4 port, 1440p 60Hz will not be possible. Use DisplayPort or replace with an HDMI 2.0+ cable.

Q: Can I get 1440p 60Hz from a laptop HDMI port? A: Most laptop HDMI ports are HDMI 1.4 or 2.0. Check your laptop''s specifications - HDMI 2.0 supports 1440p 60Hz, while HDMI 1.4 is limited to 1440p 30Hz. USB-C to DisplayPort adapters are a reliable alternative if your laptop has a USB-C port with DisplayPort Alt Mode support.

Q: Why does my 1440p monitor only show 2560x1440 at 30Hz in Windows even with DisplayPort? A: This usually means Windows has defaulted to a conservative refresh rate. Open NVIDIA Control Panel or AMD Software, navigate to Display > Change Resolution, select 2560x1440, and manually set the refresh rate to 60Hz or higher from the dropdown.
