Gianluca Sartori (@spaghettidba) blogged about the issues you may have noticed with older versions of Management Studio on HiDPI, UQHD, or 4K/5K screens in his post, “SSMS in High-DPI Displays: How to Stop the Madness.” Essentially, Windows tries to scale things for your DPI settings and, depending on the technology used to render your fonts and dialogs, this can end up with ugly and sometimes unusable screens. Gianluca’s fix is to make a registry change and add a manifest file to the SSMS directory so that SSMS no longer tries to render Windows’ scaling changes. In the latest builds of SQL Server 2016, SSMS now acts as if the manifest file were in place. Take a look at the following image:
That’s music to my ears; I use a high-resolution laptop and before Gianluca’s solution, it was impossible to use SSMS. I’m looking forward to SSMS 2016, but probably won’t move until the add-ons I use are supported; I’ve grown to like them too much to make the jump, even on a trial basis.
