I don't know why ella quoted parted of my op and didnt say anything else, then you replied to her lol. Anyway after about 5 resets it worked. No issues since.  I have a Dell dock (not sure which version, but it looks like a wd19) at work and it is super loud, one reason why I've not considered one at home.            
Yesterday I got my new Alienware monitor hooked up, no issues with the monitor. The laptop screen, when plugged into the Logi Dock, did a quick screen shift like it acknowledged the dock. Shortly after, the monitor got the hdmi signal and I could see the desktop in ultra wide mode. Everything worked perfectly through the morning. I get home today, hook up my laptop to the dock and my monitor is now showing black bars on the side like it's outputting the standard aspect ratio or resolution to my monitor. I check the display settings, I see the resolution appears different. I'm pretty sure it was showing 3440x1440 (recommended) yesterday, but today is showing 3456x2160 (recommended). It's odd how the recommended res changes. Today, under advanced display it shows display 1 internal display instead of Dell AW3423DW. I can click on display 2 to show the monitor but yesterday it was defaulting to the external. HDR is now showing not supported, yesterday both HDR capabilities were supported. I've restarted the computer 3 times now and there have been no changes in the issues today. I can click on the 3440x1440 but something is not right because the HDR issues still exist, when I close the laptop lid the monitor blacks out (which it didn't yesterday), and the recommended res does not match yesterday either. Other than keep restarting and hoping it works what could be causing this issue? Thanks
