Product Overview
AI-generated summary
If you’ve got older VGA sources you can’t easily replace—think legacy CCTV monitors, old training PCs, or industrial kit with VGA out—this StarTech VGA-over-Cat extender kit is a pretty pragmatic fix. For the money (about £118 ex-VAT for an 80m class run) it’s the kind of “keep the client running” solution that beats rewiring whole sites. The key win is reach without needing an expensive active matrix setup, and StarTech generally doesn’t cut corners on the boring stuff like connectors and build quality.
That said, I wouldn’t buy it if you’re trying to do high-end gaming/graphics work, or if your signal environment is noisy—VGA is more forgiving than digital in some ways, but it can still show softness, flicker, or colour/contrast quirks over long distances. Also, make sure your Cat5/Cat5e cabling is solid and properly terminated; bad patching will hurt these extenders more than you’d expect. Overall: buy it if you need a straightforward legacy VGA extension over structured cabling and you can trust the cabling; skip it if you can move to HDMI/DisplayPort or if the visuals need to be razor-sharp for lots of motion or fine UI detail.
