TRENDnet TK-400K

The TRENDnet TK-400K is a 4-port PS/2 KVM switch kit that has VGA and PS/2 connections between computers, and supports most operating systems.

The TK-400K comes with a high-quality 1920 x 1440 resolution, giving it a crisp and clear display for all operations.

This kit comes with device monitoring with auto-scan and audible feedback, making it an ideal system for operating multiple PCs. This system has a beeping sound to confirm when ports have been switched properly, and an LED display for easy monitor switching. It also comes with the 'Hot Plug' feature which allows you to add a PC or remove the connected PC for easy maintenance without powering down the KVM switch or the other PCs.
This model is related to the TRENDnet TK-408K, which is also a 4-port PS/2 KVM switch, but it comes with an audio kit and has a 2048 x 1536 high-quality resolution.
