    The monitor is seems smarter then usual: * High-definition digital imaging.

    This monitor's native resolution is 1600x900, which is not one of the common resolutions for TV. Thus, all content will have to be scaled to the monitor's native resolution. But if the monitor does not have its own scaler, it will NOT work with the HD-DVR, and will only work on a computer, since a computer video card can do its own scaling.

    If the monitor's native resolution was 1920x1080 (or 1280x720), then you could have configured the HD-DVR to use that (and only that) resolution, and it would work, because the HD-DVR can scale all content to that resolution.

    Chances are that this is a budget monitor and has no digital scaler built in, which means it's never going to work in this application.

    I had a 22" Acer monitor with almost the same specs, though native resolution was 1650x1080 (or something like that). I used a simple HDMI-to-DVI cable, and set my HR20-700 to 720p. The monitor scaled it to it's native output. If I tried 1080i, I would get the "No Signal" message.

    Every now and then I'd get handshake issues (due to HDCP). Whenever this happened, I'd leave the HR20 turned on, and had to physically remove the power cable from the display. Wait 10 seconds, plug the power cable back into the display, and it would work again.

    Hope this helps.

    I think if you would read specs of the monitor you wouldn't be so sceptically persistent:

    * Cinematic 16:9 HD format
    * Fully compatible with the latest HD digital content. Perfect for HD game consoles, Blu-ray™ formats, digital broadcasting or online media.



    *
    * Sharp detail
    * With a generous contrast ratio of 10000:1, you’ll view images and data in sharp detail.

    *
    * High-definition digital imaging
    * The DVI interface with HDCP support optimizes your high-definition graphics.

    That is the cable I bought. If what you're saying is true is that cable just a scam? It didnt work with my Hr21 and Westinghouse tv (it has a VGA input) either so I think that is the case.

    Also it was significantly cheaper when I bought it. (something like $8)

    Perhaps, analog signals going thru that [very special] HDMI output somehow.

    But for normal HDMI [TDMI signaling scheme] the simple cable cannot be used.

    That's a crazy elaborate scheme to rip people off. It makes sense when you explain it that way. Also "Resolution: 1080p" is that even possible with vga?

    Just for kicks, I'll hook it up with just those RCAs tomorrow and see if even that works.

    Actually yes, some high end analog monitors ( remember those bulky Sony CRT ?) can handle at 72 Hz higher resolution then the HD 1920x1080x60 Hz.

    Wow! I've never seen such a cable before, and for good reason: there's simply no way that would work.

    HDMI is all digital. The connections on the other end are all analog (VGA, composite video, analog stereo audio). Without some kind of converter box in the middle to handle the conversion, there's simply no way this cable would ever work for anyone. It's about the same as selling special "left-handed" screwdrivers or something.

    Those types of special cables are for special devices. Some projectors and special displays can take odd inputs through normal input methods.

    Sorta like how many projectors can work with a simple component to VGA cable, but very few monitors can handle both formats on a VGA input.

    Just return it as non-working and demand full refund.

    not sure it wouldn't work if you were going from HDMI to VGA or RCA. Definitely not the other direction.

    For such cable direction is irrelevant. Doesn't work. Busted !

    That is a VGA to RCA-style cable, sending RGB+HV. The thing is, both VGA and component are analog. You know this though.

    Just thought I'd follow up with this I ended up getting an HDMI/DVI converter and the monitor works perfectly. It does only work with 480p and 720p tho. 480i and 1080i don't work.

    It's all about the resolutions your monitor supports.
    Glad you got things working :)

    I thought HDMI was digital only. Maybe that cable was designed as a hack to allow people to use cheap HDMI switchers with RGB / sound?

    Odd for sure, the product could use a clearer description.
