4 x 2 KVM Matrix with Mouse Roaming Function and Full-Frame PBP Function, 4K HDMI KVM Switch allows users to operate 4 computers and select two different PC video sources to display on two monitors or one PBP monitor. The Full-Frame PBP feature means that the video sources can be displayed on the PBP screen in full screen (filling your entire screen) without any distortion and black edges.
When a PBP monitor or two monitors are connected to the KVM switch, the Mouse Roaming feature enables the user to move the cursor across the monitor boundary (one PBP monitor connected) or across the monitor boundary to another monitor (two monitors connected). Users can seamlessly switch between 2/4 computers (depending on model) by moving the mouse cursor and gain control without pressing a button or placing a shortcut command.

PBP KVM switch with EDID parsing and emulation function achieves full-screen PBP demonstration, especially on 16:9/21:9 displays, making full use of every pixel on the screen. Often, many KVM switches have no image scaling feature and cause flickering or image distortion in the PBP. PBP KVM EDID parsing and emulation function supports split screens from two different video sources, enables horizontal and vertical PBP fast switching, produces undistorted image and preserves aspect ratio in multi-screen setups.
