Predator XB271HK Unable to get full resolution on monitor after update How can i roll back firmware?

Martymoo

 I have an Acer Predator XB271HK 4k Monitor, recently after the latest nvidia driver+app update, i have had a black border/frame around my screen. I have tried numerous things problem solving the issue(listed below). I “think” firmware got installed to the monitor during the update, somehow reducing its max resolution. To back that up, when i turn on the monitor before any PC connection, the boot-up screen is also not max resolution. I am not entirely sure, but i am currently unable to find any firmware online for my monitor. Best i could find was drivers for it, which didnt fix anything. I could be wrong, but am deffinetly in need of some help!

What i have tried so far:

Replugging it in :D

Monitor Factory Reset

Reinstall Monitor Driver

Disable/enable GPU

Uninstalled nvidia drivers+app. reinstalled to previous driver i had before the issue, no fix Resolution Settings are correct, checked scaling options, all are fine.

I use multiple monitors, so have tried just booting with the problem one. And reinstalling the above a 2nd time.

Tried on both inputs Display Port+HDMI.

Nvidia has a screen rescaling option, but will not extend anymore. Adjust Size/Position(currently maxed

Hi, you can't roll back firmware, you can try to roll back a driver version but if that option is greyed out that is not possible either (see red box on picture)

What you can try is Restore the system to an earlier point (before the update), type Restore in Search and click on "Create a restore point" and "System Restore" with a date:
