<p class="info-desc">
Higher refresh rates (such as 120Hz, 144Hz, 165Hz, 240Hz, 350Hz, 480Hz, etc.) may or may not be supported depending on the cable connection (a DP 1.4 or HDMI 2.0 or higher cable is required),<br/>
the performance of the PC (including CPU specifications and graphics card capabilities), and the user environment.
</p><p>※ The refresh rate of the monitor may vary depending on the performance of the user's graphics card.</p>
<h2 class="tit">Try this</h2>
<p class="info-desc">If the refresh rate is not displayed correctly on the monitor, check the refresh rate from the PC display settings and ensure that a DP 1.4 or HDMI 2.0 (or higher) cable is connected.</p>
<h3 class="sub-tit">  Checking the Input Refresh Rate (120Hz and Above) </h3>
