AI-generated summary
For £75.54 ex-VAT, this StarTech unit is only “worth it” if you truly need a simple two-source HDMI/VGA-to-HDMI *switch* into one HDMI display. It’s the kind of box that saves hassle in a meeting room or training space where you occasionally plug in an older laptop (VGA) and newer ones (HDMI) and don’t want to keep swapping cables. The automatic and priority behaviour is useful when people are sloppy with handoffs—your display won’t sit blank as long as one source is active.
That said, it’s not the right choice if you’re expecting it to be a modern, bulletproof AV solution for mixed resolutions and picky devices. These converters/switches can be a bit inconsistent with how legacy VGA sources sync and how quickly switching happens, and you may still get occasional “works after a second” moments depending on the laptop and projector/monitor. If you’ve got reliable HDMI-only sources, spend the money elsewhere (or avoid conversion entirely). If you’re dealing with real-world VGA legacy gear and just need dependable input selection, this is a sensible buy—but if your environment is latency-sensitive or has “temperamental” projectors, I’d test before committing.
