Earlier this week, I picked up a new desktop (5820k, 980ti) and a 27" display (Asus PG278Q). It's a nice machine and a beautiful screen, but I'm struggling a little with the 2560x1440 resolution. In some programs, like in Renoise, GUI elements and text are just too small for my less-than-perfect eyesight.
Windows 10 has a setting to scale the screen (curiously, it doesn't have settings to individually scale just text or just icons, which I think previous versions offered), which I set to 125%. This works fine with some software (like Firefox, File Explorer), and not so well with other programs where everything is displayed blurry and fuzzy (like Renoise, Steam client, Device Manager).
In case of Renoise I worked a bit around this by going into the compatibility menu (shortcut) and selecting "disable display scaling on high dpi settings", and going with "huge" fonts in the Renoise preferences. This helps, but the font and elements in the Renoise menu, effects devices, instrument selector, disk browser, channel headers, etc. remain very small (sharp, but tiny). I can read the text, but it causes more strain if I'm a reasonable distance away from the screen, i.e. not three inches in front of it.
Is there anything that I can do to improve this, or is this just how it is? 2560x1440 isn't that obscenely high a resolution, and I'm not sure what I'd do on 4k when that finds its way to me eventually. I hope it's just something I'm overlooking or don't know about. (In comparison, the new vectorial GUI of FL Studio works superbly well in this resolution, but I use Renoise substantially more often.)
