4K monitor & Wacom Cintiq / Illustrator Bounding Box Issue
I'm working with a 4K monitor & a 22HD Wacom Cintiq (1920 x 1080) on a PC with Windows 10.
I use Adobe CC 2015 latest update, applications, haven't upgraded yet.
The 4K monitor is a recent addition and am noticing problems moving across monitors in Illustrator.
I've scaled up Windows Display settings 200% so the UI isn't ridiculously small on the monitor, keeping the Cintiq settings at 100%.
This was a suggested way of working with a higher res display, so the UI is correctly scaled.
When I pull the Illustrator window across to the Cintiq the UI looks fine on Illustrator at 1920 x 1080, as it scales back to 100%.
When I draw a square it draws correctly however the bounding box is not the correct size or position (see image), which is weird, it's as if only the bounding box is picking up the 200% scaling of the 4K monitor on the Cintiq.
Working with the Wacom Cintiq on my Macbook Pro is fine, and the resolution of the Macbook Pro is higher, 2880 x 1800.
So I only assume this is a Windows issue, are there any known ways to resolve this?
Photoshop does not scale correctly at all, it displays on the monitor at 200% and is too big to even work with.
Wacom don't offer a 4K model as far as I know, so an upgrade isn't possible, I can set my 4k monitor to 1920 x 1080 and it works fine, but I need the 4k monitor to work with video, so not a useful workaround, plus I feel it should display correctly.
