U2414H - Power Saving Mode FIX (HDMI)

Hello guys! 

I bought 3 of the most beautiful monitors I could find, the U2414H..
But the experience as many other was horrible, because Displayport wouldn't work decently.
The same goes for HDMI. When using the HDMI cable, I often recieve "Power saving mode", where i have to turn off the monitor, and on again for it to work.

But as a twitch livestreamer, I use a HDMI capture card, so I decided to go that way.
So my setup looked like this:

PC->HDMI_SPLITTER->Main screen
The rest of the screens were connected without HDMI splitter.

The main screen was the ONLY one that did not enter Power saving mode.
So I bought 2 more of the same splitters, and connected between the monitors - and it worked!
Since then I haven't seen the Power Saving Mode.

The HDMI splitter i used had a EDID duration of 4 seconds and was HDCP compatible.

A total of 200$ for 3 screens, but it works.

Unfortunately I do not have a fix for the DP, but this post might help.
