TRENDnet KC-302DP-A KVM Switch 3 Computers 2 Monitors 4K 144Hz

Three-computer dual-monitor control

The TRENDnet KC-302DP-A is a DisplayPort KVM switch that lets one keyboard, mouse and two monitors manage three separate computers. It targets professionals who need to operate multiple workstations or gaming rigs from a single desk without swapping cables. Each system connects with two DisplayPort cables and one USB cable, while four USB 3.0 ports share peripherals such as printers, webcams or storage across all three machines. The package includes built-in cables and a 1.5 m wired remote for convenient placement.

Upgrade from single-monitor or two-system switches

Users moving from a single-display KVM or a two-computer model gain a second monitor and a third computer port in one unit, which is valuable when workflows span multiple PCs or when a console and two workstations must share peripherals. The switch supports DP 1.4 signalling, enabling resolutions up to 8K@30Hz, 4K@144Hz, 4K@120Hz and 4K@60Hz, plus 2K@165Hz for high-refresh gaming. The jump is worth it when desk space is limited but multitasking across three systems and two screens is essential.

Plug-and-play setup with external power

Installation requires no drivers on Windows 11, 10, 8, XP, Vista, Chrome OS, Mac OS or Linux; simply connect the cables, attach the supplied DC 12 V power adapter and press the front button or the wired remote to change sources. LED indicators show the active computer. Common issues arise when cables are not rated for 8K bandwidth, causing flicker or blank screens, or when the power adapter is omitted, leaving USB ports underpowered. Using certified 8K DisplayPort cables and keeping the power supply connected resolves most problems.
