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).

Customer Reviews

Part Number: SW-29831

Pros: 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.Cons: I have not encountered any problems with this product.Other: Thanks again for hooking me up with such an easy solution.
