I suggested earlier that maybe he meant HiDPI (the 2013 Windows standard) but there was no response. He was saying HDPI, which is an existing standard, but it’s not HiDPI. You may be right that he was misspelling HiDPI but since I’m new to Cubase I would have no way to make that presumption.
How are we getting off topic? I’m trying to understand the nature of Alexander’s technical problem to see if I can reproduce it, and the nature of his (lack of-) support from Cubase problem so I can anticipate whether I might face similar problems if I buy the product. Both of those seem completely on-topic.
