I would doubt that is the cause of the problem. USB provides limited power. The device can't suck out anything else. But if it did then it would more likely be a problem with the computer (poor design) and now the computer has a problem. You didn't mention how old the computer/monitor is. They do fail. I have a failed monitor sitting on the floor next to my desk. That specific brand fries capacitors every couple of years. So I just need to break out the soldering iron open it up and replace them.

Thank you for your kind and informative reply. The monitor is an ONN brand. The computer is a refurbished DELL OptiPlex 7040. Each are approximately 2y old as best as I recall. Oddly enough after turning the computer open side down to shake out any roaches which may have made a home inside the problem has not reappeared for several hours now. This also coincided w/ reading of the fix to the CrowdStrike outage which I assume does not affect me though it seems to have affected my doctors' office as they canceled my appointment for today for that stated reason. Thank You Again Most Kindly

The OptiPlex 7040 was introduced in 2015, so you are talking about a 9 year old computer, not a 2 year old. If the problem manifests as the screen blanking out, and this disappeared after "shaking" the computer, I would suspect a soldering that has gone bad after nine years - not so bad that there is no connection ever, but vibrations can make it crack up, breaking contact, another shaking might bring the pieces together again. (Isn't that Gyro Gearloose who fixes cars by giving them a proper kick in the right place? :-)) I agree with jschell: This probably has nothing to do with your USB Power Delivery. Even in USB 2.x, there was a negotiation between the consumer and the USB controller, the consumer asking for so-and-so many units. If this is within the capacity of the USB Host, there is no problem. If the request exceeds what is available, the host says: Sorry Dave, I'm afraid I can't do that, and it simply won't deliver what it can't deliver. In any case, a USB interface has so little to do with your display interface that there is little probability that a problem with one would affect the other. I can imagine a poorly designed USB circuit not handling overload properly, causing other USB devices to fail - but not the display interface.

Not to be picky, but maybe he bought it after 2015? Is it possible that they made that model for a few years?
The difficult we do right away... ...the impossible takes slightly longer.
