While it is not a new concept, I just had the pleasure of setting up 3 monitors via DisplayPort daisy chaining. Using a Lenovo ThinkCentre M92g and two HP z24frg3 monitors plus another HP monitor, I was able to connect DP out from desktop to 1st monitor, DP out from that to 2nd monitor, DP out to a 3rd monitor. Windows 10 automatically handled the screen extension just fine and dandy. We did try a 4th monitor but the video card wouldn’t pick it up. STILL 3 monitors using daisy chaining is a HUGE benefit for cable management and port savings. You can see on this picture below the DP in and DP out. This monitor is about $250 each.
