1 out of 5 eggsDo not buy!!!

Pros: none! It would be great if it worked at all.

Cons: Never worked! I've tried in every possible way following each step in the manual and in the proper order connecting screens and power supply in a very particular order.

Manufacturer Response:

Hello David,

We are sorry that the SP123DP has not worked as desired for you. We would like to help you.

Were you not able to achieve any signal whatsoever? We suggest testing different DisplayPort cables with the SP123DP, just to make sure they are functional. Also, would you be able to let us know if the LED is on when the power adapter is connected?

Please also note that if you are converting from DisplayPort to HDMI or DVI, you will require active adapters to achieve this.

If the unit has no function out of the box, we can easily replace it for you under its two year warranty. Please get in touch with our Technical Advisors and reference case number 303-205109, and they will happy to assist you.

You can also respond here and we will be sure to follow up.
