I have a suggestion that might improve your experience with Studio 2022 on a 4K display. Below are the settings that I used for my end for a 4k screen. This is not perfect, but for now it seems to be working rather fine.

You need to right click your Trados icon, choose Properties and then go straight to the Compatibility tab. There select the following setting (sorry, my Windows is in Polish, but you should be able to find the corresponding option in your system as well):

AND also select the "Change high resolution DPI settings" (or something similar in English) to look like that (Replace high resolution DPI scaling and choose System).

Then apply changes, do not change anything in the last setting "for all users". Just accept and restart your system (this step is important; without restarting my Studio began doing weird things scaling-wise). Now my Studio looks like that with proper scaling and no blurring. I really hope this helps

I started to suppose, that possibly using Studio on localised Windows versions other than English or German in my case might be a cause for problems. None of the problems you describe appear here. And I do work and prepare projects at the same time. Currently I work on a project with two memoQ files of over 65k words in total. No crashes at all.

And I never changed any such settings which you show here.

That is an interesting point. If that were the case, that would be... concerning. I do hope, however, that this is SDL/RWS-related problem, not a Microsoft one ;).

This is not the first time, that someone with Polish Windows is reporting massive problems with various versions of Studio. I have seen many such claims on Facebook before I left the corresponding groups. As a really heavy user of Studio I nearly never could reproduce such behavior on my various machines over the years. And I use German Windows since ever... Same for the Studio 2022 now. Even the betas do behave, although these do crash more often than production versions (as they are beta and I am testing them to help make them more robust). Of course Studio produces more error messages than for example Word. But the TO3000 version 11 (not 3D) crashes more frequently here (sometimes several times per day), so following the usual trend I'd suppose this software is worse than Studio. There are also other programs crashing, but TBH I do not experience big problems with any software used here.

Wow—this works! I changed my Windows settings as you described and disabled the third-party "Change Scaling Behaviour" add-in, and the effect is the same: proper 4k scaling! Mateusz, you should be working for Trados Support, since you're smarter than anyone I've ever encountered there!

I'll try once again to upgrade (finally) to 2022 with the hopes that this will work there as well.

For anyone else following this thread, here are the English-language Windows dialog boxes. Right-click on Studio/MultiTerm icon, select Properties, then configure as follows:

Then click the Change high DPI settings box near the bottom and configure as follows:

Confirm and reboot.

Just for my understanding: you use high-resolution screens in Windows, but the Windows scaling is NOT set to 100%? Just to understand what is happening here.

For my built-in 13" laptop monitor, my scaling is set to 250% with a resolution of 3840x2400 (=4k).

For my external 27" monitor, my scaling is 125% with a resolution of 2560x1440.

For each display, these are the Windows-recommended resolutions, though I have personalized the scaling, (Windows recommends 300% and 100%, respectively.)

And it's important to note that I tried all manner of settings, but Trados always scaled wrong. It's the ONLY program that has this problem. All Microsoft programs and all other third-party programs were fine.

Thanks. Now I understand where your problem is coming from. I do not use scaling. I buy a 4k monitor and like to use every pixel. Using scaling does not make any sense for me. If you scale 4k to 200%, you can as well buy a full HD screen to have the same effect.

Just my personal view, no offence.

Thanks! I was happy to help. I don't remember where I picked this solution, but I am glad it helped you as well. Perhaps sometime in the future Studio will utilize this solution (somehow) out-of-the-box as well. Until that time comes, however, we've got a workaround. Have a nice evening!

I now also see where you are coming from - my computer uses 200% scaling too (its a 15" laptop) for interfaces, so without it reading anything from Trados menus would be difficult. It seems that Windows scaling does not work properly with Studio for some reason, and only using Trados in compatibility mode manages to overcome this issue. Perhaps this is something that RWS support could take a look at? Maybe the solution (for future reference) is simpler than one would think? I hope this thread helps everyone with their scaling issues.
