This is an old article which is even more valid, as higher resolution screens are more frequent nowadays – but our eyes are still the same… However, the moral may be extended: either the screen must be readable in its native resolution or in a quarter of it, or buy this type of device:



Recently I have bought an expensive personal computer, because the others are rather used ones and have more and more problems. (And I should not hide one of the most important factors; my son has also bought a new notebook, however, his motivation was a little simpler: his old machine has just stopped, like a nail…) Of course the poor old Full HD resolution is not cool anymore and touch screen is a must, not to speak about the WWAN network (mobile net with SIM card). So finally I’ve essentially bought a gigantic, 14″ mobile phone with 2560×1440 pixels screen resolution, quite a good computing capability (i7 processor, 16 GB RAM) and a Windows 10 operating system. It _is_ a good buy (to avoid cognitive dissonance I’ve thousands of arguments to validate my decision anytime)!

Today Microsoft has asked me via the Feedback app the probability whether I would propose my new Windows 10 PC to the other fellow humans. Here is what I’ve answered:

„- It is a couple of weeks old only, has all the patches, however, it had stop once and it did not shut down (I had to switch it off by the power switch) 3-4 times.
– The 2560×1440 resolution is just awkward. It cannot be used natively on a 14″ screen, and using it at the proposed 200% scale produces small resolution. And there are programs which just do not recognize the scaling (especially the Java-based ones).”


The most important moral: the screen must be readable in its native resolution or in a quarter of it. For me and for a 14″ screen it is the Full HD (1920×1050). The native resolution of the notebook is 2560×1440 pixels, that screen is just not readable – at least not for me. If you don’t want to see a distorted picture the next usable resolution is the half for each direction – i.e. the quarter of the original screen. This is just 1280×720 pixels in my case – horribly small (yes, I know, I have started with 320×200 on 12″ monitor…).


So I use the screen in the native resolution and a 150% screen scaling to make the letters readable. However, there are programs (especially the Java 8-based ones) which just do not recognize this setting and still appear non-scaled – consequently unreadable.

Also a good 27″ Full-HD monitor is connected to the notebook, so I can utilize that one to view those mighty programs. But not. This second monitor has a scale of 100%, of course.

And when I move the window from Screen 1 to Screen 2, Windows reduces its scaling from 150% to 100%, meaning to distort the window remarkably. An example:

There is a window of 100×100 pixels. When it is displayed on Screen 1, it is scaled up to 150%. When it is moved to Screen 2, it is scaled back to 100%. That is the theory – and as we all know, practice matches theory – at least theoretically…

In practice, windows of programs running on Java 8 do not scale up on Screen 1, however, they are do scale down to 75% when they moved to Screen 2.
