I recently upgraded from a 60Hz monitor to a 240Hz one during a Black Friday sale, but I can't seem to notice any difference at all. My advanced display settings confirm it's set to 240Hz, but when I test it on TestUFO, it only shows 90Hz. I'm not sure if I'm missing something or if the monitor is defective. Could my eyes also just not be capable of seeing the difference? This is my first experience with a refresh rate above 60Hz.

Good point about checking graphic acceleration in your browser! It might not be a game-changer, but it's definitely worth a look. Also, remember to only have one browser tab open for testing and try closing any RGB software or mouse applications that might interfere with the display.
After you’ve confirmed the refresh rate in the Advanced Display Settings, ensure that your monitor is the only one connected and powered on during the test. If you see any sync errors, that could indicate an issue affecting detection.
Make sure you've set your monitor to 240Hz in the Advanced Display Settings on Windows. Sometimes, you might have to dig into the Nvidia Control Panel if you're using an Nvidia card, or the AMD settings if you have an AMD graphics card. You need to double-check all those settings to ensure everything is correct.
