Matrox Graphics has always been renowned for professional video and graphics applications and even achieved some success in the 3D gaming graphics boards market in the late nineties. Unfortunately for the privately-held Matrox, companies like ATI Technologies and NVIDIA Corp. had much more money and experience to invest into research and development of 3D accelerators, which is why Matrox had to abandon its high-performance 3D graphics projects several years ago. Nevertheless, the company still has quite some potential in the fields of 2D and video editing markets and is capable of producing unique devices, one of which is recently announced DualHead2Go product.

Matrox DualHead2Go Dual Analog Edition is an external adapter that can be plugged to an analogue output of any graphics card and then divide the resolution by the card across two displays which are also connected using D-Sub connectors to the DualHead2Go adapter. The devices supports 2048x768 resolution (at 60Hz, 75Hz, 85Hz) and 2560x1024 (at 60Hz) resolution primarily allowing to connect a couple of 15? 17?and 19?LCD panels.

AnandTech web-site has had an opportunity to review the Matrox DualHead2Go adapter. The authors managed to dissect the part and explain how it works. In addition, the article contains some basic information that will help those who try to set the part up. The article logically claims that while the DualHead2Go has potential for certain customers, it is useless for average users, which once again proves Matrox's business model to create niche products for professionals.

?The bottom line is that there will be some people who absolutely must have this for business or other reasons, and those people will find the DualHead2Go useful. But for the average laptop owner, the price will probably be too high to justify doing whatever he/she would really like to do with it,?the author believes.
