I previously posted a review saying it failed after 2 months. Fortunately, I received a replacement shortly thereafter. Unfortunately, 3 months later I am back there again. It failed exactly in the same way - blank screen (audio/usb/power keeps working). It seems to have something to do with using HDMI and USBC at the same time, because both this and last time it happened when I had both ports in use. Buyer beware - don't waste your money on this monitor.
I got a pair of these for Christmas, the KVM is a lifesaver and easily lets me dock my laptop (XPS15) for when I need productivity. Attached to my desktop these things are good for gaming and great for general usage and productivity.
