One more bonus, for anyone who yet comes upon this. I bought a monitor, once upon a time, a Dell UP2414Q, as I recall. It was a nice monitor, when it worked. Unfortunately, there's a terrible secret in high-framerate high-resolution stream transport - for at least some protocols (hello DisplayPort), they do this by sending two video streams for halves of the screen and the monitor muxes them. Unfortunately, on this monitor, it would go...wrong, sometimes. Sometimes, it would think that the picture on the "right" half should be stretched to fit the entire width, and then the left side displayed over that on the left (or vice-versa). Sometimes, it would just display nothing for one side. Most excitingly, sometimes it would just do what I would describe as "crash" - if the monitor was allowed to go to sleep, it would sometimes just...stop responding to any inputs on the physical buttons or commands from the computer, and require a hard power removal and reinsertion of the power cable before behaving again. So you got to leave this monitor non-asleep the entire time or endure suffering. You can see a fun comparison of what a screenshot thinks is onscreen versus a photo of it in [1][2]. And all of those things could all happen any time the resolution shifted - switching to/from fullscreen in something, for example. If you look, you can find references to a revision of the monitor which ships with a firmware that lacks these problems, but there exists no documented path to update from one to the other. I could not, when I looked, find someone who had the access and desire to try and extract the firmware from the board without any sort of provided tooling to do it, and I was not going to buy monitors with that model and hope I found one of the right rev. Dell support might have been willing to replace it under warranty, but I had bought it refurbished, so "ha ha". Ultimately, I gave the monitor to someone as a gift when theirs was woefully insufficient (with complete disclosure of the flaws in it) before I tried flashing any exciting payloads. Probably the least satisfying story ending of these, but true.
