I'm running Resolve in dual display mode (Windows 10 - scaled 150% on dual 32" 4K displays). When on the second display, anytime I right-click for a context menu it's opening far right of where I clicked. This happens when clicking scopes menu options also. A bug perhaps and also a continued issue with Resolve and high dpi displays using Windows scaling?

Display Scaling should always be set to 100%. (Things do often go weird when you change that.)

This seems to be true only in Resolve. I should point out when using scaling, that images and videos continue to display at 100% while the UI is what is scaled.

Every other app I use works flawlessly (i.e. Adobe Suite, C4D, Modo, Allegorithmic, Zbrush, Blender, Silhouette, C1Pro, etc.) when used on 4K displays with scaling. Also, for those that use 4K displays (I believe there are many of us) scaling is essential in virtually all apps. If this is yet another buggy UI result of using scaling in Windows 10 then BM would be doing a disservice to a portion of their current and future user base if they continue to ignore the importance of properly supporting 4K displays and scaling. Very frustrating indeed.

I use a 32" UHD display myself. No scaling is necessary.

Are you only working primarily in Resolve / Fusion? For those of us working in many of the other post production apps (i.e. generalists) this is an issue and working on 4K displays at 100% is an issue. Again, stills and video aren't scaled when working on them, just the UI. This makes for the best of both worlds where playback is fantastic since a 1080 video played at full resolution takes up 1/4 of the display and the UI is sized to both see clearly and optimized for usability/space.

I don't understand why there's pushback from others on the BM forums when functionality like this is requested. Working well with Windows scaling is available in virtually every other post production app I can think of and use. A solution is needed within BM Studio asap if you ask me and likely every other customer who works in a 4K display environment.

I have three machines sharing the same monitor with a KVM, so I do all kinds of things on it. My video work, photo work, browsing, email, office, accounting, games, etc.

What other programs are giving you trouble at 100%?

Scaling is absolutely necessary on a 32" UHD display. 150% is the sweet spot. What do Blackmagic give us? 100% or 200%.

This forum is littered with users having exactly the same issue. I reported this as an issue over 5 years ago and nothing has been done. BM employees don't even bother to post on threads about it now, presumably out of embarrassment. It's an absolute piss take.

I suppose I'd be a major rework of how they render the UI in Resolve. Not having multi monitor aware scaling in 2021 is a no go, but I'd assume they solved it if easy. You may well have multiple monitors with different DPI. Supporting scaling on one is just the first step.
