Depends

Should I use Gefen?

Professional AV over IP, HDMI, DVI & KVM solutions. Quality video distribution, matrix switches & extenders. Trusted AV technology experts. - gefen.com

· 1 month ago

Buy if you're an AV integrator or enterprise deploying video walls, extension, or KVM at scale. Skip it for simple home or small-office HDMI needs, and patch firmware fast if you deploy.

Confidence

Medium. Based on ~60 public sources; many 'Gefen' results refer to an unrelated kosher food brand, so AV-product evidence is thinner than it appears.

Full analysis

Based on ~60 public sources; many 'Gefen' results refer to an unrelated kosher food brand, so AV-product evidence is thinner than it appears.

Legacy pro-AV brand (now Nice-owned); strong for integrators, overkill for basic HDMI, mind the 2025 RCE CVE.

Methodology

Based on ~60 public sources; many 'Gefen' results refer to an unrelated kosher food brand, so AV-product evidence is thinner than it appears.
