Use MulDiv(some_value_when_on_96, Screen.PixelsPerInch, 96) when needed (setting sizes and coordinates from code for example).

Make sure all forms have their Scaled property set to true.

High-DPI enable the application using a manifest.

To conclude, this is what I did for my Delphi application (and that actually, and as I said, didnвЂ™t take too long): I guess you will end up reading more high-dpi articles than those listed above вЂ“ but this gives you a nice вЂњwhere to start fromвЂќ guide.

How do I make my GUI behave well when Windows font scaling is greater than 100%ДЄ great discussion on StackOverflow talking about high-DPI enabling Delphi application before Delphi 10.Seattle. RAD Studio 10 Seattle is the first RAD Studio to easily let you say your application IS DPI aware. New per-DPI awareness in VCL applications Also repeat what is stated in the first article but from the perspective of a Delphi developer. How-To Guide: Upgrading Your Delphi VCL Applications To Support 4K Displays This is not directly Delphi related вЂ“ rather Windows related вЂ“ but this is where you start. Differences between non-DPI aware application, DPI aware applications and per monitor-DPI aware applications. This is where you start to get the idea whatвЂ™s happening.

Writing DPI-Aware Desktop and Win32 Applications So, hereвЂ™s the list of must-reads you want to go through to understand why your super nice Delphi application appears so ugly or so small on your friends laptop: As when I started I really had to read a lot and make sure I understand whatвЂ™s happening and what should be best done. Now, I want this post to be more of a collection of guidelines for (myself and) those just starting to fight the high DPI battle. Not to mention you can have more screens attached to your computer and each screen having different resolution and more importantly different scaling factor.

And this is where the problems start! Your Delphi applications will probably look super (small or stretched) ugly if the application is not DPI aware or will look messed up if the controls you use do not know how to scale themselves (and the application is DPI aware). ThatвЂ™s supper small and not usable! This is the reason why Windows turns on DPI scaling by default so stuff on such screens becomes bigger (except your 16Г—16 px glyph on that button which remains 16Г—16 px and is barely visible, ha!). Just imagine a standard glyph of 16Г—16 pixels on your standard TBitBtn.

If you think Full HD (1920 x 1080) is big, what do you then think of 3480 x 2160 pixels? WhatвЂ™s worst is that those high resolutions tend to be used on small laptops (e.g. The thing is that todayвЂ™s laptops and desktops come standardly with (very) high resolution screens. If you do not know what IвЂ™m talking about then you are kind of blessed.Д«ut, sooner or later you will find yourself searching the Internet for keywords including: Delphi, 4K displays, high DPI, form / control scaling / sizing, DPI awareness, PixelsPerInch, DPI virtualization in Windows and alike. Alas, what takes time are those few (third party AND VCL) controls that refused to be properly scaled so you really have to test on various screen sizes and various DPI levels. There are really just a few things that need to be done in your Delphi application to make it properly DPI aware. It was not a too hard job вЂ“ it just took a lot of time and experimenting (read: fixing) how the UI of the application appears on various 4K displays having various settings for вЂњ Make text and other items larger or smallerвЂќ (Windows Vista/7/8), which is the same as вЂњ Set a custom scaling levelвЂќ (Windows 10).ДЄctually, saying that вЂњhigh-dpi enablingвЂќ took a few weeks is wrong.

Woohoo! After a few weeks of struggle IвЂ™ve finally high-dpi enabled my used-across-the-globe Delphi application.
