If the resolution setting is incorrect when the TV is connected to a PC, it may result in symptoms like screen cut-off and enlarged screen.<br>
In this case, set the optimal resolution by consulting the TV user manual.<br>
Right-click on the Desktop, select Screen resolution, and change the display resolution.

<strong class="tip-tit">Checking the HDMI cable</strong>

<div class="con-view">
It is recommended to use an authentic HDMI cable to connect your TV with a PC.<br>
Using a non-certified HDMI cable may lead to communication errors, resulting in symptoms like a jittery screen and shaking screen.<br>
Authentic HDMI cables are labeled or engraved with the "High-Speed HDMI" mark. Otherwise, the cable is likely not certified.<br>
In this case, replace the HDMI cable with an authentic one.<br>
Check if your HDMI cable has the “High-Speed HDMI” label or engraving (HDMI 2.0 or higher version is recommended).
