Hammerhead by Sewell

VGA to HDMI Converter, 1080p

"Very fast shipping. Good job!"


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).

Great Product

Loving it - 6/11/2012 7:17:17 AM

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.

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.

This product is awesome. I have an older laptop that has no HDMI port on it. I searched the net for something that would allow me to go from a VGA port (laptop) to a VGA port (monitor), and then I found Sewell Direct, and found the Hammerhead, which, had the VGA to HDMI, and my monitor has an HDMI port. I was thoroughly impressed with the ease of connecting it, and I was even able to interface with my 55" LED TV. The price was most definitely right, as I had found other solutions but they were 3 to 4 times the price, and looked more crude to interface with. The Hammerhead is a compact, easy to connect wonder. I have been using it for going on 3 years now and it works beautifully. I just want to thank Sewell Direct for providing this easy and affordable solution.

Products was well packed, and shipped fast. I was unable to test unit because of an issue with my older computer. I contacted Customer Service, and received a R/A number for a return.

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.
