I have an issue such that when I place my application (which is based on a RadRibbonForm) on to my right hand 4K monitor and then maximise it I get a small amount of "bleed" of my application on to the right hand side of my left monitor.

On inspecting the forms desktop bounds property it see X = 1908, Y = -12, width = 3864, height = 2114. I was expecting X = 1920, Y = 0, width = 3840, height = 2090 which is what is being reported in Screen.AllScreens.

I'm using the latest version of WinForms and have done what is suggested in this link.

I can reproduce the same behaviour when I run "Demo Application - Telerik UI for WinForms R2 2022 SP1", move it to my large right hand monitor then maximise it.

Kind regards
Toby
