I've attached a quick video of my setup to let you see the end result. I typically require this setup for admin documents and getting live information on the side monitors, but for the purposes of demonstrating the screens I've put 4K video feed on each screen.
I'm not sure how well it will come out on the video as it's compressed, but the displays are excellent, the 4k content comes out very vibrantly and the smoothness is incredible, if there is any lag it will be from my laptop struggling to process 3 x 4k monitors at the same time!
Now for the negatives and the reason it's not getting 5*. The speakers have rubbish volume capabilities and are tinny sounding at high volume, but thats not a consideration for me as I didn't purchase them for the speakers. However the other issue is that I use my setup at night and the monitors lowest brightness setting still feels too bright. More flexibility with the brightness controls would be great, or a mode for using at night.
Overall I highly recommend these monitors!
