Model: TP-122XL
from $308
The Kramer TP-122XL is a compact receiver designed to extend computer video (UXGA) and stereo audio signals over a single twisted pair cable. It accepts input from a 15-pin HD connector and a 3.5mm mini jack, then outputs to an RJ-45 connector, supporting resolutions up to WUXGA and 1080p. With a remarkable range of over 820 feet (250 meters) using CAT 5 UTP or STP cable, this receiver is ideal for applications requiring long-distance transmission of high-quality video and audio signals, such as in classrooms, conference rooms, or digital signage installations.
Matching your monitor's resolution and refresh rate capabilities with the KVM is crucial, as many budget switches cap out at 4K 30Hz or 1080p. Ensure it supports the exact number of monitors and computers you need. Available from $308.
KVM switches require very little electricity and have no consumables. Ownership costs are effectively zero beyond the initial purchase and required cabling.
