Custom Resolution Utility (CRU)

[anor_wondo]

Hello. I am having trouble with removing a resolution.

My monitor is 3440x1440 144hz native(BenQ MOBIUZ EX3415R). It has a 3840x2160 mode inbuilt that I want to remove.

The issue is that it is only getting removed if I remove the unreadable 'Default Extension Block', but along with it, my native 144hz is also removed.

I've tried manually adding 3440x1440 144hz but the utility doesn't allow it(pixel clock limitations?).
