HDMI to VGA conversion -

Using the basic cox box HDA250 DT - Trying to use an HDMI out to VGA converter but doesn't work. Anyone know why? The HDMI / VGA converter works fine connected from a HDMI laptop port to a VGA in montior. But NOT on the cox box to VGA port on monitor. The monitor I want to use only supports VGA or DVI input only.

HDA works fine when connected via HDMI to HDMI to a different monitor. I suspect cox isn't following standard HDMI protocols? Any ideas?

Hello, have you tried using this VGA converter with other receivers in the home? I only mention this because you mentioned that it works with a laptop HDMI. Digital media connections, like HDMI and DVI, are required to be HDCP-compliant. High-bandwidth Digital Copy Protection (HDCP) is an industry-standard security system designed to prevent the unauthorized copying of digital content. -Kevin M. Cox Support Forum Moderator

I agree with Kevin on the copy-right protection. HDMI was fundamentally created to prevent recording. If your device is just a TV or monitor...fine...HDMI will toss keys back-and-forth to enable viewing. I'll assume your convertor...the HDMI endpoint...just isn't responding to protection negotiations.

A computer by nature is a recording device because it has storage; therefore, there may be no copy-right protection on its hardware but instead its software. For example, if you wanted to watch Cox programming via a computer, you're probably limited to watching via Cox software...which has no recording ability.

I don't know much about HDCP but I'd assume your cable box just doesn't like the convertor.
