Bought a 144 Hz monitor and it still feels like 60? Check the cable and two settings

This is one of the most common hardware questions there is, and the answer is almost always one of three things. 1. The cable and port can carry less than you think Refresh rate times resolution needs bandwidth, and older HDMI versions cannot carry high refresh rates at high resolutions. - HDMI 1.4: typically 1080p up to about 120 Hz, or 4K at 30 Hz. - HDMI 2.0: 1440p at 144 Hz, or 4K at 60 Hz. - HDMI 2.1: 4K at 120 Hz and beyond. - DisplayPort 1.2: 1440p at 144 Hz and above. - DisplayPort 1.4: 4K at 120 Hz and above, more with Display Stream Compression. Use the cable that came with the monitor, plug into the graphics card, not the motherboard's video output, and use DisplayPort if your card and monitor both have it. 2. Windows is set to 60 Hz Windows does not always pick the highest rate. Settings, System, Display, Advanced display, then choose the refresh rate. On macOS, System Settings, Displays, Refresh rate. 3. The game is capped Many games have their own frame-rate cap or V-Sync setting, and some default to 60. Check the game's video settings. If your frame rate never exceeds 60 regardless of settings, the cap is somewhere in the chain. Checking it worked https://www.testufo.com shows your actual refresh rate and frame rate in the browser. If it says 60, the problem is the cable, the port or the operating-system setting, not the game. Variable refresh G-Sync and FreeSync smooth out frame rates below the maximum. Enable it in the graphics driver's control panel and on the monitor's own menu; it needs to be on in both places. Post your monitor model, graphics card, cable type and what TestUFO reports, and the fix is usually one reply away.
