Yes, I believe that's what we're talking about. I suspect this same installer has been modified and upgraded for a decade without changing that background. I do not have the script, but I am trying to figure out how to resolve these DPI issues using my own test scripts so that I can provide a solution to the author of the script. If I should have the installer author remove the background in order to resolve this, I can work on that.

For all screenshots, note that this is a windows VM at 3840x2160 running on my macbook pro and the screenshot is taken from my macbook pro.

Could you please send a screenshot from the dialog on your 4K monitor (not from the "blue" background because this is only there for backward compatibility and should not be used in modern installers).

BTW, and could you please launch this Microsoft MSI setup and post a screenshot from the MSI dialog on your 4K dialog.

So that you have a full spectrum answer:

Here's a screenshot of the VM with the display settings next to the dialog:

Here are a couple of photos of my 4K monitor, with the windows VM running in it at a resolution of 3840x2160 and the MSI dialog on the screen:

Here's a screenshot of the MBP monitor setup for the 4K monitor:

I hope this conveys what we're trying to resolve and gives you the info you need. BTW, the end user who brought this to our attention was at 250% magnification on Win10 on a 4K monitor, with no VM or other complicating factors.
