Headless Ghost HDMI Display Emulator Looks Useful, At Least For Some


Despite the name, the Headless Ghost HDMI Display Emulator isn’t some kind of Halloween prop. It’s a tiny HDMI dongle that mimics a display and fools a computer into thinking it’s connected to one. This is for people who often remotely connect to display-less machines, and who would benefit from being able to do so at full resolution. You see, many PCs automatically lower the output resolution if they don’t detect a display, some even going as far as disabling the graphics card altogether. But if you’re running software that would benefit from having the GPU chugging along, like cryptocurrency mining software, then the Headless Ghost is especially useful. As a matter of fact, if you have a farm of machines built specifically for that purpose, you’ll be happy to know that you won’t be needing a display for each PC, but that an inexpensive £10 (~$16 USD) dongle will do. It can mimic resolutions ranging from 800×600 to 4096×2160.

Ice Cream Sandwich On A Stick Isn’t What You Think

By David Ponce

If you’ve got a nagging urge to get your Android action on that big fat HDTV you just purchased, a company called Always Innovating might have something for you. It’s an HDMI dongle that is essentially a little PC all on its own. It’s got its own TI Dual Cortex-A9 OMAP 4 (1 to 1.8GHz) processor, 256MB to 1Gb of RAM, WiFi and is capable of 1080p video decoding. Oh, and it’s running Android 4.0, also known as Ice Cream Sandwich. The idea is that you take any ole TV, plug this into the HDMI port and off you go, running Android as if that TV was a mobile device. You can run apps, browse the Internet, watch movies and do whatever else you’d do on an Android device.

Always Innovating isn’t selling these directly to the consumer, instead opting to license them to third party vendors. They expect to see them in shelves come summer 2012, for a price somewhere between $49 and $99.

[CES 2011] Rainbow Fish Fiber Optic HDMI Cables

Your regular copper cable-based HDMI cables are probably more than sufficient for most consumers. But for professional applications, and of course those home-theater video/audiophiles, a Chinese company called the Rainbow Fish Corporation will soon have a fiber optic-based alternative available. The advantages to using fiber optics over copper are of course the lack of any electromagnetic interference which also requires less shielding, hence a thinner cable, and dramatically increased transmission distance. A rep from the company claims you can send an HDMI signal down a 900 foot fiber optic cable without any loss in quality. And without the need for a repeater.

But there’s always a trade-off, though thankfully this time it’s a minor one. Unlike standard copper HDMI cables which you can just plug in and have work, fiber optic-based HDMI cables require a power source, which in this case is pulled from a USB port. You’ll find that most modern hi-def TVs have at least one USB port on the back, but if not you can always add an AC to USB adapter to your TV’s power strip. The Rainbow Fish fiber optic HDMI cables will be available in a few months, with pricing info to be announced later.
