Re: [DUG] Screen Resolution and WIndows 10 settings and Delphi
Thanks, a lot of useful comments, especially about external monitors. As far a the comment who still develops new applications in Delphi – well most interested to read what is better and your reasons (I may have something to say about a new application shortly – and it is Delphi)___ NZ Borland Developers Group - Delphi mailing list Post: delphi@listserver.123.net.nz Admin: http://delphi.org.nz/mailman/listinfo/delphi Unsubscribe: send an email to delphi-requ...@listserver.123.net.nz with Subject: unsubscribe
Re: [DUG] Screen Resolution and WIndows 10 settings and Delphi
Hi John I no longer have Delphi installed, but I occasionally have to use other older software. Under older versions of Windows I had the same issues with scaling that you describe like text not fitting inside the (fixed size) control, and sometimes that made that particular software difficult if not impossible to use. Under Windows 10 the scaling looks just like somebody zoomed the display in. Modern software looks fine, but with the older software the GUI is fuzzy like you are using the wrong monitor resolution, but as everything is uniformly larger the text still fits the control. Now useable but not pretty. For me monitor choice depends a lot on what I’m doing. I find that developing software in an IDE can work well with multiple monitors as most IDEs have many smaller windows that can be moved to a secondary monitor. I do quite a lot of graphics work where a single large monitor is vastly superior to a collection of smaller monitors. I purchased a large monitor before I got Windows 10. Due to the issues with older software I wanted to stay at 100% scaling. Due to my eyes getting older and using the monitor all day every day I wanted each pixel to be a reasonable size so text was still large enough at 100%, so the pixel density (pixels per inch) was important to me. I also wanted lots of screen real estate, 4K resolution or better. I looked for quite a while before a suitable monitor came onto the market, but now there are quite a few options. A “4K” resolution at close to my desired 109 pixels per inch (diagonal) gave me a 38” 3840 x 1600 wide screen monitor. I’d definitely buy it again, but I wouldn’t want a monitor that had less vertical resolution. A 3840 x 2160 monitor would be great, but for me I’d want that to be in something like a 40” diagonal body to keep the text readable at 100%.

Re: [DUG] Screen Resolution and WIndows 10 settings and Delphi
I just ported my application from xe7 to 10.4 … 10.4 has full support for modern dpi and font-sizes … but 3rd party controls just aren’t there yet with support for it and even very simple things (such as adjusting the x/y/h/w of a control) requires quite a bit of calculation. I found porting an existing large application to be quite challenging and had to give up on supporting dpi-scaling. For a new application it could probably be done – but then, who still uses Delphi to develop new applications?! Kind regards, Stefan Müller, R Manager ORCL Toolbox Ltd.

There are also different levels of support, like dpi aware and also per monitor dpi aware. High DPI support in the IDE is an ongoing issue with the latest releases. It is much much better than what it was. It just scales the control, you can check out the source code for what is happening, just search for the DoAfterMonitorDpiChanged method. Old versions of delphi with a DPI other than 96 will be horrible and inconsistent with the presentation. The per monitor support is interesting. Each control has a current dpi property as you can't rely on Screen.PixelsPerInch anymore.
