"Ordering process was easy and product arrived faster than I had expected. Thanks."


Convert any VGA signal with audio to HDMI with the Sewell Hammerhead (HDMI cable sold separately). This innovative new product is the smallest VGA to HDMI converter on the market. Don’t be fooled by the small size of the Sewell Hammerhead. This product packs a heavy punch, converting VGA to full 1080p resolution. The Hammerhead requires no additional power for standard definition displays and includes an optional power supply for high definition. The Hammerhead allows users to connect any computer that outputs VGA to any HDMI TV or display. With so much free content online to watch these days, you can now get it from your computer to your big screen HDMI TV with this simple converter.

Minimum Lag For Gaming

The Sewell Hammerhead is also a preferred adapter for those needing to connect gaming rigs to their HDTVs. With a 43 millisecond lag, this adapter is a great choice (anything under 50 milliseconds is undetectable by the human eye and inconsequential).

Pros: This is a great product everything about it is great. From the ease of installation to the quality of the output performace. It truley converts VGA to HDMI and the digital sound quality is outstanding. IF You want to convert your old VGA signal to HDMI this is the way to go. In most cases it's cheaper than replaceing your PC PCI video card witch can be difficult to find and can be more expensive then this item, and much much more easier to install. Check this item out and I am sure you too will be just as pleased as I am.

Cons: What? Cons

Other: For those of you who thinks this item dosen't allows you to go full screen, you have to ajust your resolution on your computer display.

Works as Intended

Pros: I am seriously happy with my purchase. This device worked perfectly for my wife and myself right out of the box. The only issue I had was due to user error (Switched TV to wrong HDMI input channel during installation *facepalm*).


Other: I would definitely recommend this item.

It does exactly what it was advertised to do. I purchased a Dell M6500 laptop which does not have an HDMI port; only VGA. I needed something just like the Hammerhead! Thanks, Sewell!

Good Product

What is the amperage needed to externally power the Hammerhead? Can I connect it to an external usb AC charger?


That should work fine. It will need to be DC power (not AC), 5V and 500 mA.
