I've seen a few people with this issue a while ago but it doesn't appear to be fixed. I have a Vaio Canvas Z (windows 10). I hook it up to a dell monitor via the hdmi cable.
the UI scaling just doesn't adapt to the extended monitor. Even when I change it to 100% scaling, the menu headers are fine but as soon as you click file or edit, the drop down content is giant.
Can you guys please fix this? it's ridiculous when every other app can adapt to different display settings.
