Best Use Cases
First, laptop users who lack video outputs: If your notebook only has USB ports, this adapter lets you connect a DVI monitor without needing a docking station. It's particularly useful for ultrabooks and thin-and-light laptops. However, it is not suitable for gaming or GPU-intensive tasks due to the DisplayLink overhead. Second, business travelers frequently giving presentations: The combination of DVI and VGA support covers most projectors found in conference rooms. The compact size fits easily in a laptop bag. Be aware that if the projector only has HDMI, you'll need an additional adapter. Third, individuals wanting to repurpose old VGA monitors: With the included DVI-VGA adapter, you can use a legacy VGA display as a secondary monitor. This is a cost-effective way to set up a dual-screen workspace. Note that the maximum resolution is 2048x1152, so it may not satisfy high-resolution display needs.
