Dell in dead heat with Asus for "Moronic Button Implementation"
I have previously mentioned that the 4K Display that Apple pushed for awhile, the Asus/Sharp 321 has an insanely inelegant means of switching from SST to MST. (8 buttons pushed in odd order for a total of 10 button pushes to go from one to another)
I was having an issue with my Dell 5K tonight where it would show a boot screen then go to black. I finally found this article online that described my predicament.
You can skip reading the whole page, the gist is this statement from a Dell employee:
"Workaround = Disable monitor Sleep from OSD (On Screen Display) Menu- Energy Settings- Monitor Sleep- Disable). This may help speed up Sleep/Wake cycle by about 1-2 seconds."

Now here is where we get to the Catch-22 Part.
I kept trying to use the buttons on the side of the display to access the OSD. But no matter what button I pushed, all I ever got was the "switch from 4K to 5K" choice. Out of 5 buttons, 4 took me to this function. The last button was the power button, it still did what it normally does. It seemed I was locked out of getting to the OSD to fix my black screen problem.
Then I saw this gem in the manual:
"Activate the computer and wake up the monitor to gain access to the OSD."

It turns out that the only way to use the OSD is to HAVE SOMETHING ON THE SCREEN. As in, you must have a computer outputting an image on the screen to be able to get that Menu button. When nothing is connected it goes into sleep mode and you can't access the OSD to make sure it doesn't go into sleep mode and cause a black screen which means you can't fix it.
I tried to navigate the Dell website to get some help, totally lost cause. If you wanted to make an Opaque website that kept anyone from finding any information whatsoever, Dell would be a good model.
So, I booted another card and in the brief moment that there was something on the screen I hit button 3 and LOW AND BEHOLD THE OSD APPEARED !!!
And I was able to disable "monitor sleep" which will hopefully keep me from getting locked out of changing settings again.
And for anyone using this display with a cMP, I would advise turning off display sleep in the OSD. If you ever get to see it.
