Just upgraded from Vegas pro13 to Vegas pro14 suite but I found that the interface text an menus Looks blurry in 4K monitor(3840x2160) all my other programs looks perfectly not Vegas,I tried many different display settings without satisfactory results, help please
My suspicion is that you will have to await later versions of Vegas. I've experienced the same thing on a UHD laptop--most everything looks blurry compared with other applications such as Photoshop. E.g., toolbar icons using V13 could hardly be seen on my laptop. Now in V14, they can be seen, but are blurry since Vegas still requires each icon to be 16px x 16px and not larger.
This is one of the known issue right now.
I don't have the 4K monitor, so I can't see it by myself how bad the blurry is.
There are many tools - for example also Edius - who are not ready to run on an UHD monitor alone, simply becaue the GUI cannot be scaled up. So for those applications it is still a good idea to run the GUI on a HD-monitor, and use the UHD-monitor for the UHD preview as secondary display mainly.
