On the 29UM69G, the split-screen is software-based, not hardware. I use the LG 49WL95C-W and the split screen software 'OnScreen Control'. Here, the software windows automatically adjust to the preset width of the individual segments - only with Sandboxie-Plus this automatic adjustment of the size does not work. Hi guys, For those with any of the LG Ultrawide screens - is the screen split feature software based only? I was looking at buying one of these for gaming and work, but can't install software on my work laptop so would need it to be possible to activate via hardware buttons on screen too.
There are ways to work around UAC without disabling it in this case. I know, because I wrote MaxTo [maxto.net], which does much the same things, and works with software running under UAC.

If you want MaxTo to work with UAC, you'll need to run MaxTo elevated. If you say deny elevation, it simply won't work with elevated software.

I'm pretty sure LG just took the 'easy way' out (or they may have nefarious purposes, but I won't speculate), instead of figuring out how to communicate between elevated and non-elevated processes.
To do this sort of thing, you'll need to divide your software into a few parts. First and foremost, you'll need to install a global system hook. That hook has to be written in unmanaged code (meaning C/C++). You'll need software that controls the hook (but it can be written in a managed language). Now, both the controlling software and the hook has to be compiled as both x64 and x86 code. They will probably also have to communicate with eachother across the x86/x64 platform boundary. This war of mine: the little ones.
Now, to get the software to communicate (using window messages) across the UAC boundary, you have to specifically let Windows know which window messages your app will accept from the other side. This is probably the step they missed. You do this by using ChangeWindowMessageFilter [microsoft.com] or ChangeWindowMessageFilterEx [microsoft.com].
