Since upgradeing to windows 10 when ever I clone my image over 2 displays either 1 or both goes to 720p. I have a normal 1080p 60hz monitor and a 51 inch samsung TV both are 1080p both 60hz never had an issue with windows 7 and I use the feature alot when viewing pics movies and websites with family. Its annoying and I cant find a fix any help would be awsome
Ok figured it out when I right click then go to display settings on my desktop screen 1 was set to 150% while screen 2 was at 100%. was scratching my head for days even did a complete OS wipe and reinstall seems silly to have that setup on default. At least its all good now
