Making sure I understand - Powered USB brick to power DP splitter?  I haven't heard of it, but it doesn't mean it doesn't exist.  Or simply a powered DP splitter. What I did find is powered HDMI splitters.  But I'm not the king of monitors in this forum, so I don't know if you would get 2 separate screens or if they'd just be mirrored. I don't know what's all plugged into your USB's.  But a powered USB hub could help.  Flash drives consume a little power and I think WiFi dongles do to. The 3080 micro comes with 65w PSU brick.  The 5080 comes with 90w brick and optional 130w brick.  Same for the 7080 + optional 180w brick.  If you wanted to use a higher watt brick, I don't know if they'd work on the 3080 micro, but might not take much to research to see if power plugs are the same. Reason I thought of DP not having enough power for a splitter is because a few years ago, I'm at an appt.  Noticed the Dell micro's and asked about them.  Complaint was it seemed like USB's didn't have enough power.  Something like couldn't use more than one USB at a time and there were issues with trying to print that didn't exist with their previous PC's.
Hi. I have a Dell Optiplex Micro 3080 hooked up to a DisplayPort Splitter: [URL] . The hub connects 2 x Samsung C27F396FHN 27" LED LCD Monitor - 16:9 - 4 ms - 1920 x 1080 - 16.7 Million Colors - 250 cd/m² - 3,000:1 - Full HD - HDMI - VGA - 25 W - High Glossy Black  and then I have a TCL monitor plugged into the HDMI port. It works for the most part without issue, but randomly, the computer will crash. All three screens will get a bright color pink, green, blue distorted overlay all over them, if the speakers are on it'll make a loud buzzing noise, and then I'll need to hold the power button to turn it off and reboot. There is no BSOD. Nothing in Windows logs from what I can tell besides a critical shutdown alert after the fact, but no alert prior, and there isn't anything I can do to replicate or find any commonality.  Has anyone had this issue before? All drivers, patches, and BIOS are up to date. It's seemingly random, though thinking about it, it might happen when I'm doing a screen share or remote logged into a PC if that helps give any clues. I've racked my brain and bringing this to the community for some help.
