    Awesome for office

    Awesome docking monitor, connects easy, set up is easy, the screen quality for office/productivity is awesome. I am not sure if it would be good for gaming but in the office this is amazing.

    The picture on this is great

    It has plenty of ports and adjustments, it's actually confusing which usb ports to hook up and why to hook up ethernet and the directions don't explain. It may be if you're using a KVM or docking station?But using 5k x 2k resolution, even though I've increased the font size it's nice and clear. A good replacement for my prior 5 yeah old curved monitor which I accidentally broke.

    Able to return, but monitor received broken

    After several delays in shipping, contacted seller and they told me it was going to be sent by fedex instead of ups. Monitor arrived, but did not work. Contacted dell and they said it wasnt working and had to contact seller since monitor was assigned to them. Seller was good in providing shipping label to send back and refunded money.

    Ein Traum, ein wahrer Traum.

    Ich komme von einem Dell/Alienware 38", der eigentlich noch sehr gut ist. Dieser Monitor setzt ab noch einen obendrauf. 5K bei 120Hz ist schon schön. Der Monitor ist ein Schnittstellen-Wunder. Diesmal hat Dell alles geliefert, was man braucht. Meine Dell-Docking Station für meine Laptops konnte ich abbauen, ich verwende nur noch den KVM im Monitor. Die ausfahrbaren USB Ports sind eine gute Idee, wenngleich ich diese eigentlich nicht benötige.Die Qualität ist sehr gut. Es wird hier Geren behauptet, dass die Lochmaske für einen 39,5" Monitor bei 5K zu groß ist. Da kann ich nicht zustimmen. Ich s

    Excellent for Developers, Good at gaming, suprisingly good at movies. Very expensive.

    This is a beautiful monitor. I bought it primarily for coding and some gaming. It fits 3 panes of code in one screen, or 2 panes plus codex. I can feel my brain juggling less between tasks.Gaming is also very immersive, I'm playing older AAA games on my legion because 5k2k is a very high resolution. It also works well with my Mac through thunderbolt and charges it too.Always remember to use thunderbolt on Mac and displayport / usbc displayport on Windows. HDMI is a bit hard if you are pushing 5k2k 120Hz.Very beautiful very capable very expensive monitor.

    Excellent, wish I'd gone down this road much sooner.

    Absolutely worth every penny (and that's a *lot* of pennies). Does everything it says it will. Very high quality build, exceptional clarity and flexibility in scaling (Mac OSX) make this monitor the only one I need now. Wish I hadn't hesitated so long, as I understand it was quite a few quid lower in recent history. The pass-through USB / power ports means it acts like a dock, with all the peripherals connected through it, I just plug my macbook into the thuderbolt cable (supplied) and off we go. The software for monitor settings and window management is surprisingly good too. Putting it toget
