Acer XB240HA ULMB Issue not working and gets BRIGHTER

Hi I have really huge problem. I decided to try ulmb is cs go beacuse it wasnt too smooth on gsync. After 30 minutes of playing with ulmb which was awesome I swapped in nvidia drivers to gsync mode. After that when I tried enable ulmb again it immidiatly gets so bright like 300% more than standard mode on gsync. Now even on 10% brightness is bright as hell. First I thought it was driver issue so I reinstalled it without any success. Is there any way to restore all settings factory dafualt settings? Or should I rma it? Please help...

PS. Its the same as here

Gamesiarz,

While I do not see anything on the US posted for your monitor in regards to this issue, contacting the Acer technical support in your area would be the avenue you would need to take (as we discussed in PMs) to see if there is something on their end. I have sent a message on to see if there is anything that we can do to help you out.
