SDL Trados Studio 2019 supports Windows 8.1 and Windows 10.
As a minimum requirement, we recommend an Intel or compatible CPU-based computer with 4 GB RAM and a screen resolution of 1024x768.
For optimum performance, we recommend a 64-bit operating system, 16 GB RAM, an SSD drive and a recent Intel or compatible CPU. Full support for 4K hi-resolution screens is planned and will be implemented incrementally in future releases. You can find more information on how to deal with display issues in this KB article or by running an application from the SDL AppStore which implements a fix in the aforementioned KB article.
Note: SDL Trados Studio 2019 uses .Net Framework 4.7.1.
