Dual Monitor Y-Cable
I did, some years ago, implement a couple of dual monitor solutions with Dell machines using a Y-Cable provided by Dell (using a DMS59 socket on the computer). I'd like to do that at home now.
I have a Radeon 7850, which has a fully populated DVI-I-plug (i.e. two monitor signals). I want to buy a DVI-Y-cable, connect two monitors to it, and let Windows 10 (1511) create a Desktop which spans these two monitors (monitors have same resolution and frequency).
Now, I read on Amazon a lot of talk that you actually cannot do that with a Y cable, you can only have the same content on both monitors. Which is the opposite of what my own experience tells me, and also seems unlogical, since there are two fully equipped data channels which can provide a horizontal resolution of at least 2560 pixels, and I have done this before, a few years ago, and it worked.
Can anyone please she some light on this for me - am I missing something? Can this be done with my graphics card and a Y-cable, or do I need some sort of active box which splits the signals onto two monitors for me?
Thank in advance for all comments!
