![]() Users who need more USB ports were given an cheapy external powered USB 3.0 hub and I convinced their management to crack down on them using rando peripherals.Īll of that said, I found this thread today looking into the input lag issue. That solved the issue and has been good for a couple of months now. Simply removing the K&M in this scenario solved the issue.įor this user I gave him an external powered USB 3.0 hub. Initial trouble unit had a wired K&M (some random brand gaming RGB stuff), external USB disc drive, printer, headphone dongle and an iPhone charging cable plugged in shared between displays. Too many USB devices or too thirsty of a USB device plugged into the displays and they simply shut off the ethernet port first. It wasn't until I started underthinking it and started working backward that I identified that it was a physical power issue. Some of the power options suggested here and elsewhere on the web aren't even available on older drivers.It was repeatable with every single HE model we tried.Ethernet was flickering itself on and off repeatedly. Didn't matter if we imaged the machines with the newest driver injected or rolled back to an even older driver. NONE of the driver updates or tweaks solved the initial ethernet drop issue.Some things I have identified in our usage scenario: U2422HE using MST/daisychained to a U2422H via DP cable with a USB A/C cable between them. So sad we bought those monitors, too much problems with them.īeen having the same issues with the U2422HE via USB-C. If someone had solved thoses issues, share pls ) We tried everything, FW updated (which takes like 60-75 minutes), disabled always charging mode, sacrificing a chicken. When people come back at the office, and plugged the laptop to the USB-C connector, sometimes the monitor seems to stay in standby mode (no led on the monitor), the only way to get the display of the laptop back is to unplug/replug electrically the monitor :(.When users type with an external keyboard, sometimes, some letters are wrote multiple times (like if the keyboard letter is stuck), example: for "hello", it can write "hellllllllllllllllooooooooooooo".We updated the Realtek USB GbE Ethernet driver to the 10.49 version (i think :p), and in the advanced properties of the driver, we disabled the following options :īut we have others problems with those models :/ We had the sames issues with the LAN with our U2422HE, Is anyone else seeing issues with this model? There was a firmware update for the monitors released a few days ago that supposedly fixed the issue with frequent LAN disconnects but it does not seem to help. All machines are using the same build of Windows 10 and drivers have been updated with Dell Command Update. We use a mix of 7410 and the newer 7420/7320 machines and the issue does not seem to affect the older 7410. Another big issue that I have is frequent wired LAN disconnects and reconnects when the user is using a Dell Latitude 7320/7420 machine. When the problem persists I will plug the wireless adapter into the laptop itself and mouse/keyboard functionality is restored. Sometimes moving the wireless adapter to a different USB port helps and other times I need to reboot the monitor. ![]() There seems to be random USB lag with the Logitech keyboard/mice that we use. ![]() We recently upgraded our entire office to the U2422HE monitor with built in dock and have noticed a few issues.
