Review on Enhance Productivity with Dell U3419W Ultrasharp 34 Inch 🖥️ Ultrawide Screen - 3440X1440, 60Hz, USB Hub, Wall Mountable, Height Adjustment by John Tarnowski

I really like the monitor apart from a very annoying firmware bug (mentioned by at least 1 other reviewer). If you have two or more different computers connected to the monitor, the computer on the unselected input is allowed to turn off the monitor (put it to sleep, the screen goes black or blank). Suppose Computer 1 is connected to DisplayPort and the operating system is configured to turn off the monitor after 15 minutes of inactivity. Work on this computer and then switch the monitor to computer 2. Exactly 15 minutes later, Computer 1 tells the monitor to turn off, and it turns off even if you're working on Computer 2. If I enter the Monitor menu and select With an input already selected, the screen reappears as if nothing happened. This problem occurs at least on the DisplayPort and USB-C ports. Later I will try to use the HDMI ports with another computer. I suspect it's not that hard for Dell to fix this in firmware, but trying to convince them of the problem through their support lines is a nightmare. Their only suggestion is to replace the monitor, although all evidence indicates that a replacement will have the same problem. I would appreciate if someone else could duplicate and report this issue via a 1 star rating. I don't know how else to motivate them to tackle this problem. I suspect they won't waste engineering time looking for a solution if only one person complains.
