do not waste your time or money on a graphics amplifier. It has been the worst experience of any piece of tech i have ever owned. I have spent more time trying to get this thing to work than it is worth. There is little to no support for the device and Dells advice is just to uninstall things and hope that it fixes the issue. It has not. Dell takes responsibility for nothing, and it is near to impossible to receive support as my laptop is out of warranty. However, my laptop is not the issue. It is the additional $800 i spent to upgrade it on the graphics card and amplifier. please do not buy this, it will literally just ruin your day anytime you boot up your computer.
