Windows 10: No ultrawide monitor support after upgrading to 20H4

I updated my computer Windows 10 Enterprise 2004 -> 20H4 last week. Ever since then, I can't get my LG 29 UM65-P to display in the correct 2560x1080 resolution. I've reinstalled the LG software SplitScreen and DualController 2.64 and updated the graphics card software to the most current AMD Adrenalin 2020 build. When I attempt to create a custom resolution to fix it in the Adrenalin software, I get an error saying the monitor doesn't support it. Windows 10 only shows up to 1920x1080. The monitor is plugged in with a DP to HDMI cable. Everything was working properly prior to the Windows update so it has to be related to a Windows setting. I'm also going to post this to the AMD support.

Dual monitor or ultrawide?

Hey guys. I am stuck between decisions. I plan on getting the GTX 1180 16gb (planning ahead) and I do alot of gaming. While I do like ultrawide but I don't want to compromise frame rates. I would like to use obs or xsplit for streaming games for fun. Thing is, I would like to do 1440p gaming. I just got myself 8700k with 16gb 3200mhz trident z rgb ram. I have my system oc to 5.0ghz.

So the real concern is, which is more preferably reasonable? A 3440x1440p g sync monitor or 2x 1440p monitors (1x g sync tn for gaming and 1x ips for obs or xsplit and viewing comments). I can always view the comments on my phone so I don't care about viewing just comments on a separate monitor.

And if I do go dual monitor, do I have to get both of the same monitors and samw resolution? Suggestions? Tips?

Thanks again!

Ps- I have windows for gaming and Ubuntu for productivity.

Can't select 2560x1080 resolution for ultrawide monitor with Windows 10 1909 Update

OK. I connected my new LG Ultrawide monitor and still have the same problem, I can only get a max of 1920x1080 resolution. I decided to do the Windows 10 update 1909. After the update, I decided to uninstall the Intel UHD 630 driver, then reboot. When
the computer started back up, the resolution was 2560x1080, perfect; however, even though it was the right resolution, on the display settings, the resolution was grayed out. Within about a minute of the reboot (all the time, the computer wheel is spinning),
the monitor blinked and it was put back to 1920x1080! I think what was happening was the graphics driver was being reinstalled. Anyone have any suggestions on what my next step should be? All your help is greatly appreciated! Thanks.
