Hey guys, I got a curveball for you. I have a Dell Optiplex 9020 that I want to have three extended displays on.

I approached it by getting a DisplayPort-to-DVI Dual-Link adapter, the adapter works. Now what I wanna ask you guys is if I get a Y splitter like this one here on Amazon will my displays be able to extend? Or will they just duplicate? The third monitor will be connected using the on-board VGA so no worries there.

The monitors in question are three Dell P2414H displays. If you guys need any more details please ask!

Even if the original port is a DisplayPort 1.2? Sorry if the question is stupid, I'm not very technically keen on how video signals work.

Read the description for the cable you linked, it even states there that the same thing will be displayed on both monitors.
