SAPPHIRE Vid-2X Display Expander



The great thing about the VID-2X is that you don’t need any software or drivers to use it. The VID-2X plugs into your dual link DVI port or a DisplayPort and that is it. The VID-2x seeks out maximum resolution of the connected displays, and adds the sum of both of the displays (height is static, but the width is the sum of both displays). The two models of the Vid-2x are Display port or DVI dual link inputs and a micro USB adapter for power which runs off a USB port. If you’re in doubt of which model to purchase (DVI or Display Port) we would suggest the display port if the system you are planning on using has a display port. If the PC does not have a display port and you are looking at the DVI model, be sure your DVI port on the PC is a dual link port and not a single link port. We plugged both models into our workstations video cards and didn’t have a single issue (XP or Windows 7). The one issue we did run into was the one laptop we were tying to use only had a single link DVI port and nothing was displayed on the dual monitors. We also tried to use a HDMI port with a converter to DVI and that didn’t work either, so be warned. WE had one more die sign problem that we found while connected the two DVI cables. We apparently had two different manufacturers’ DVI cables, and one was a little wider than normal and overlapped the second DVI port. This overlap prevented the second DVI cable to be seated square on the plug. We informed Sapphire about this and though it isn’t Sapphire’s responsibility to supply DVI cables we  suggested (if possible) to add a little space between the two DVI outputs to prevent this from being an issue in the future.

The images below show both models of the Vid-2X PSEDP4196 and PSEDV2185. The output side of dual DVIs show nothing in particular. The input side of both models came with a cable for their respected model (DVI dual link cable or a display port cable). These provided cable for the input side are a little on the short side, so if your planning on using the Vid-2x on a workstation which sits on the floor, you will likely not be able to see the readout on the display b/c the vid-2x will be sitting under your desk. NOTE: You do not “need” to see the vid-2x to use it, but if you need to see the readout or change the dip switches after, you may find the short input cable an inconvenience.

Windows XP picked up the Vid-2X without a single issue. Windows 7 also picked up the Vid-2x without a single issue too.
Also not shown here is the ability to place the Vid-2x above or up to the side of the main screen.

The resolution is determined by the Vid-2X and is sent to your GPU. The Vid-2x was detected and worked immediately in both Windows XP and 7. We used 4 screens for this review, two with a resolution of 1024x 768 and the others with 1280×1024, and both sets performed very well. We could not detect any performance degradation.
