Glad someone posted to this thread recently, because I had pretty much decided the font appearance in Roon, after the 1.7 upgrade, although not perfect, was acceptable. Right after the 1.7 upgrade, I realized that others were complaining about certain display issues, but they didn’t seem to necessarily match what I was seeing. I couldn’t figure out what was going on with my setup, but overall, it was not that disturbing.
I have a Dell XPS 8910SE PC running Windows 10 Pro in my bedroom and use it in conjunction with a Topping DX3 Pro DAC when listening at my bedroom desk to headphones and alternatively to an active PC-type speaker/subwoofer sound system. I’ve got a NUC Roon core delivering files to multiple endpoints/AV systems throughout the house, but it has been the appearance of Roon on my bedroom desktop display that has been a little disconcerting.
Anywhose, my bedroom PC monitor is a Hewlitt-Packard HP27q with resolution capability up to to 2560 X 1440, but it’s run at 1920 X 1080. Because I’m an old fart and like my desktop icons and fonts a little larger, I run the display settings set to Medium-size icons, which puts the scaling of the screen @ 125%. So, long-story-short, that made all the print graphics in Roon look like they were hand-set on an old type-setting machine (not aligned linearly – like you see in some of the above graphics postings). For a while, I thought that might have been a Roon-choice to make things look a little old-fashioned or nostalgic, but the type in the Roon Settings headings, etc, often looked double-imaged, with individual letters distorted or partially obscured – so I knew something wasn’t quite right, but they were still readable, so I just let it go. However when I came upon this thread, with posters suggesting alternate custom display scalings, I tried setting the HP with several custom scalings other than, but very close to 125%. For me, I found that 123% rendered the best type-faces throughout Roon without noticeably altering my desktop icons/font-size appearances. So, everything in Roon looks totally normal and great right now, and I guess I’m a happy camper keeping the display scaling set @ 123% (unless there is a long-term problem with that I don’t realize – as stated previously, I’ve had it set at 125% for a long-time). Apparently, the new 1.7 fonts in ROON have an issue with the previous setting I was using (125%) on my system (as well as in others’ as indicated by several of the preceding posts in this thread). So, thanking all previous posters for their input.
Just posting this as a “FYI” for others that might be encountering similar issues to what I have had – now resolved and gone
