SCREEN 📌 Quick Summary: 165Hz is a tricky refresh rate. It is often a "factory overclock" of a 144Hz panel. This means that out of the box, your monitor might be running at 144Hz, and you need to manually enable the extra speed in the monitor's hidden menu. Use the test below to check your current speed.

If you just bought a 165Hz monitor, you might be running at 144Hz without knowing it. Let's check your browser's cadence.
The "OSD Overclock" Secret
Most 165Hz monitors do not ship with 165Hz enabled by default. Why? Because overclocking the panel can slightly reduce its lifespan or color accuracy. The manufacturer leaves it disabled so the monitor is 100% stable out of the box.
To unlock 165Hz, you must use the physical buttons on the monitor (not Windows) to open the OSD (On-Screen Display) menu.
- Press the menu button on your monitor.
- Look for a setting called "Overclocking," "DP Overclock," or "Refresh Rate."
- Turn it ON or set it to 165Hz.
- The monitor will likely reboot or flicker for a second.
Why Doesn't Windows Show 165Hz?
Even after enabling the OSD overclock, Windows might still be stuck at 144Hz. This is usually because the DisplayPort cable is not certified for the higher bandwidth. You must use a DisplayPort 1.4 cable (not 1.2) for 165Hz at 1440p resolution. HDMI will not work.
Is 165Hz Worth the Upgrade from 144Hz?
Honestly? No. The jump from 144Hz to 165Hz is only 21 frames per second. It is virtually imperceptible to the human eye. However, if you are buying a new monitor and the 165Hz version is the same price as the 144Hz version, take the 165Hz. It is free performance.
Frequently Asked Questions (FAQ)
Will overclocking to 165Hz damage my monitor?
No. The manufacturer built the panel to handle it. However, if you notice visual artifacts or flickering, drop it back to 144Hz.
Why is my 165Hz monitor showing 60Hz?
You are using an HDMI cable. Switch to DisplayPort immediately. Read our full guide on Refresh Rates to learn more.
