Using a KVM switch generally won't affect resolution, as it allows you to control multiple computers from a single monitor. However, if the monitor or switch doesn't support higher resolutions, or if there's a problem with the output interface or cable, a reduced resolution may occur.
Reduced KVM switch resolution usually indicates two situations: First, the KVM itself supports high resolution, but the actual displayed resolution is lower. This could be because the host or server doesn't support high resolution, or the output interface is damaged, or the connection cable doesn't support data transmission. Second, the computer supports high resolution, but the KVM monitor displays a lower resolution. This could be because the KVM resolution is low and doesn't support high-definition output, or the connection cable is damaged, or the host resolution cannot be set.
To resolve the issue of a reduced KVM switch resolution, the following steps can be taken: First, check the product quality, including the host, KVM switch, and connecting cables. Replace any faulty components promptly. Second, if the product itself is not faulty, the KVM resolution may be insufficient. In this case, replace the KVM switch with one that supports high-definition resolution. Finally, it is recommended to choose a KVM switch that supports EDID mode, which allows you to set different resolutions. Restarting the KVM computer will then allow it to recognize the corresponding resolution.
