Review on 🔌 StarTech.com VGA Video Extender over Cat 5 with Audio - Up to 500ft (150m) - VGA over Cat5 Extender - 1 Local and 1 Remote (ST122UTPA) - Black - Enhanced SEO by Bryan Moon

I needed to run a second security VGA monitor about 75 feet from the main monitor. This extender uses standard CAT5 unshielded twisted pair network cable (should be a direct connection between two devices, not a connection to your LAN). I can't tell the difference between a local image and a remote image, so I'm very satisfied. The only odd thing is the manual appendix, which warns the user that both devices must be grounded to avoid static electricity build-up. I didn't have an easy way to ground the boxes, so I didn't (hope they're grounded via the VGA cables). I haven't seen any problems so far (active for 2 weeks). I am very happy with my purchase. I think StarTech makes wonderful and very useful products.
